Nervous tissue
Epithelial tissue forms protective layers that line body cavities and cover organs. It consists of closely packed cells with minimal extracellular matrix. This tissue also functions in absorption, secretion, and sensation. For more detail, see Britannica: Epithelial Tissue.
Which tissue provides support and binds other tissues together?
Connective tissue
Epithelial tissue
Muscle tissue
Nervous tissue
Connective tissue supports and binds other tissues by producing an extensive extracellular matrix. It contains cells like fibroblasts, adipocytes, and immune cells embedded in fibers and ground substance. This matrix provides mechanical strength and cushioning. See Britannica: Connective Tissue for more information.
Which tissue type conducts electrical impulses throughout the body?
Nervous tissue
Epithelial tissue
Muscle tissue
Connective tissue
Nervous tissue is specialized for the conduction of electrical impulses via neurons and supporting glial cells. It enables rapid communication between different body regions. This tissue underlies all neural functions including sensation, thought, and motor control. For further reading, visit Britannica: Nervous Tissue.
Cardiac muscle tissue is characterized by which special structure?
Intercalated discs connecting adjacent cells
Voluntary control of contraction
Multiple peripheral nuclei
Unbranched long fibers
Intercalated discs are unique to cardiac muscle and contain gap junctions and desmosomes that allow synchronized contraction. These discs connect individual cardiomyocytes end to end. They support rapid electrical and mechanical coupling. More details at Britannica: Intercalated Disc.
Simple squamous epithelium is typically found in which location?
Alveoli of the lungs
Skin epidermis
Ducts of glands
Urinary bladder
Simple squamous epithelium forms thin, flat layers ideal for diffusion and filtration, such as in the alveoli where gas exchange occurs. Its single-cell thickness minimizes diffusion distance. It lines blood vessels and body cavities as well. Learn more at Britannica: Simple Squamous Epithelium.
What is the primary function of adipose tissue?
Store energy in the form of fat
Conduct electrical impulses
Provide structural cartilage
Line body surfaces
Adipose tissue stores triglycerides in adipocytes to serve as a long-term energy reserve. It also cushions organs and insulates the body against heat loss. Adipose tissue secretes hormones like leptin that regulate metabolism. For further reading, see Britannica: Adipose Tissue.
Hyaline cartilage is found in which part of the body?
Tracheal rings
Auricle of the ear
Intervertebral discs
Epiglottis
Hyaline cartilage contains type II collagen in a firm matrix, providing support with some flexibility. It forms the supportive rings of the trachea and bronchi. It also covers articular surfaces of bones. Additional details at Britannica: Hyaline Cartilage.
The main cell type found in mature bone tissue is called a what?
Osteocyte
Osteoblast
Chondrocyte
Fibroblast
Osteocytes are mature bone cells embedded within the mineralized matrix, maintaining bone tissue. Osteoblasts build new bone matrix and become osteocytes. Chondrocytes are cartilage cells, and fibroblasts produce connective tissue fibers. See Britannica: Osteocyte for more.
Pseudostratified ciliated columnar epithelium is typically located in the:
Respiratory tract
Small intestine
Urinary bladder
Skin epidermis
Pseudostratified ciliated columnar epithelium lines most of the respiratory tract, trapping and moving particles out of the airway. All cells contact the basement membrane but nuclei appear at different levels. Goblet cells within this epithelium secrete mucus. Learn more at Britannica: Pseudostratified Columnar Epithelium.
Dense regular connective tissue forms which structure?
Tendon
Dermis of skin
Hyaline cartilage
Loose areolar tissue
Dense regular connective tissue contains parallel collagen fibers providing tensile strength in one direction. It forms tendons connecting muscle to bone and ligaments connecting bone to bone. The parallel fiber orientation resists unidirectional stress. More detail at Britannica: Dense Connective Tissue.
Goblet cells are specialized epithelial cells that secrete:
Mucus
Enzymes
Hormones
Sweat
Goblet cells produce and secrete mucus to trap particles and lubricate surfaces, especially in the respiratory and digestive tracts. They appear as clear, goblet-shaped cells among other epithelial cells. Mucus secretion protects underlying tissues. For more, see Britannica: Goblet Cell.
Transitional epithelium is unique to which organ?
Urinary bladder
Stomach
Liver
Small intestine
Transitional epithelium, or urothelium, tolerates stretching as the bladder fills and empties. Cells appear dome-shaped when relaxed and flattened when distended. This specialization is unique to the urinary tract. Further reading at Britannica: Urothelium.
Smooth muscle tissue can be distinguished microscopically by the absence of what?
Striations
Central nuclei
Intercalated discs
Multiple nuclei per cell
Smooth muscle lacks the striations seen in skeletal and cardiac muscle because its actin and myosin filaments are not arranged in sarcomeres. It has spindle-shaped cells with a single central nucleus. This allows involuntary contractions in organs like the intestines and blood vessels. See Britannica: Smooth Muscle.
Elastic cartilage can be identified by the presence of which fiber type in its matrix?
Elastic fibers
Type I collagen
Type II collagen
Reticular fibers
Elastic cartilage contains abundant elastic fibers allowing flexible support, such as in the ear and epiglottis. Type II collagen is also present, but elastic fibers are the defining feature. The fibers appear dark in special stains like Verhoeff’s. More at Britannica: Elastic Cartilage.
The ground substance of connective tissue is primarily composed of glycosaminoglycans and what?
Proteoglycans
Lipids
Actin filaments
Keratin
Proteoglycans are core proteins with glycosaminoglycan side chains that trap water and resist compression. They, together with glycosaminoglycans, form the hydrated gel of ground substance. This matrix provides cushioning and support in connective tissues. For more, see Wikipedia: Proteoglycan.
Which connective tissue type is poorly vascularized and typically heals by fibrosis?
Cartilage
Bone
Adipose tissue
Blood
Cartilage is avascular, so it has limited capacity for repair. Injuries often lead to fibrous scar tissue rather than regeneration of hyaline cartilage. Chondrocytes receive nutrients by diffusion, slowing healing. More details at Britannica: Cartilage.
Reticular connective tissue primarily supports cells in which organ?
Lymph nodes
Kidney
Brain
Liver
Reticular connective tissue is rich in reticular fibers (type III collagen) that form a supportive mesh for lymphoid organs. It supports lymphocytes in lymph nodes and the spleen. The loose network facilitates cell migration and filtration. See Britannica: Reticular Tissue.
Which glial cell type produces myelin in the peripheral nervous system?
Schwann cell
Oligodendrocyte
Astrocyte
Microglia
Schwann cells wrap around axons in the peripheral nervous system to form the myelin sheath. Oligodendrocytes perform this role in the central nervous system. Astrocytes support neurons metabolically but do not myelinate. Learn more at Britannica: Schwann Cell.
Which type of cell junction creates a seal to prevent passage of molecules between adjacent cells?
Tight junction
Desmosome
Gap junction
Adherens junction
Tight junctions (zonula occludens) are comprised of claudins and occludins that seal the intercellular space. They prevent paracellular diffusion of solutes between epithelial cells. This maintains distinct compartments and barrier functions. More information at Britannica: Tight Junction.
The lamina lucida and lamina densa are components of which structure?
Basement membrane
Plasma membrane
Perichondrium
Perimysium
The basement membrane underlies epithelial cells and consists of the lamina lucida and lamina densa layers. These layers anchor epithelium to underlying connective tissue. The lamina lucida contains glycoproteins, while the lamina densa is rich in type IV collagen. For more, see Britannica: Basement Membrane.
Intercalated discs in cardiac muscle contain which junction type that allows rapid electrical conduction?
Gap junctions
Tight junctions
Adherens junctions only
Desmosomes only
Gap junctions are clusters of connexin proteins forming channels for ions and small molecules between cardiomyocytes. They enable rapid spread of action potentials across the heart muscle. Intercalated discs also contain desmosomes and adherens junctions for mechanical stability. Details at Britannica: Gap Junction.
Osteoclasts are derived from which cell lineage?
Monocyte-macrophage lineage
Fibroblast lineage
Chondroblast lineage
Osteoblast lineage
Osteoclasts differentiate from hematopoietic monocyte-macrophage precursors. They resorb bone by secreting acid and proteases onto the bone surface. Osteoblasts, in contrast, arise from mesenchymal stem cells and build bone. More at Britannica: Osteoclast.
Fibrocartilage is characterized by abundant collagen type I fibers and is found in which location?
Intervertebral discs
Auricle of the ear
Tracheal rings
Nasal septum
Fibrocartilage combines dense collagen type I fibers with cartilage cells, forming a tough, shock-absorbing tissue. It is found in intervertebral discs and pubic symphysis. This tissue resists compression and tensile forces. See Britannica: Fibrocartilage.
Desmosomes connect adjacent cells by linking to which cytoskeletal element?
Intermediate filaments
Microtubules
Microfilaments (actin)
Myosin filaments
Desmosomes are cell–cell adhesion structures anchored to intermediate filaments (keratin in epithelial cells). They provide mechanical strength and resist shearing forces. Desmosomal cadherins and plaque proteins mediate this link. More information at Britannica: Desmosome.
Which histochemical stain is commonly used to highlight glycoproteins in the basement membrane?
Periodic acid–Schiff (PAS)
Masson's trichrome
Hematoxylin and eosin
Oil Red O
The PAS stain oxidizes carbohydrates in glycoproteins to aldehydes that react with Schiff reagent, yielding a magenta color. It is widely used to visualize basement membranes and glycogen. Masson’s trichrome highlights collagen, H&E is general, and Oil Red O stains lipids. Read more at Wikipedia: PAS Stain.

Cheat Sheet
Epithelial Tissue Patterns -
Epithelia form continuous sheets with varying layers and shapes, from simple squamous to stratified columnar. Use the mnemonic "S.S.C.S." (Simple, Stratified, Cuboidal, Columnar, Squamous) to recall key types. Spotting these patterns quickly is vital for acing a tissue identification quiz when you review histology slides.
Connective Tissue Matrix Components -
Connective tissues rely on a robust extracellular matrix composed of fibers (collagen, elastin) and ground substance (glycosaminoglycans). Remember that bones, cartilage, and adipose all share resident cells - osteocytes, chondrocytes, and adipocytes - embedded in their niche matrix. Mastering these components will boost your confidence in any identifying tissues quiz.
Muscle Tissue Types and Features -
There are three muscle types: skeletal (striated, voluntary), cardiac (branched striations, intercalated discs), and smooth (spindle-shaped, involuntary). Visual cues like banding patterns and nucleus location help you distinguish them quickly. Practicing these distinctions is a proven prep for a biology tissue quiz.
Nervous Tissue Structure -
Nervous tissue contains neurons (with dendrites, axons, and soma) and glial cells supporting nutrient supply and insulation. In histology, look for dark Nissl bodies in soma and clear axonal tracts to spot neurons. This clarity in tissue recognition will make the tissue types quiz feel like a snap.
Histological Staining Techniques -
Common stains like Hematoxylin & Eosin (H&E) color nuclei blue-purple and cytoplasm pink, while Masson's Trichrome highlights collagen in blue-green. Periodic Acid - Schiff (PAS) stains glycogen and mucins magenta, helping you identify basement membranes. Familiarity with these stains elevates your performance on any tissue identification quiz.
