Which layer is the outermost layer of the epidermis?
Stratum corneum
Stratum basale
Stratum granulosum
Stratum spinosum
The stratum corneum is the outermost layer of the epidermis, consisting of dead, flattened keratinocytes that form a protective barrier against pathogens and water loss. It is continuously shed and replaced by cells from deeper layers. This layer is essential for skin’s barrier function. NCBI
Which cell type produces the pigment melanin?
Melanocyte
Keratinocyte
Fibroblast
Langerhans cell
Melanocytes are specialized cells in the stratum basale that synthesize melanin, the pigment responsible for skin and hair color. They transfer melanin granules to keratinocytes to protect nuclei from UV damage. Their activity determines individual pigmentation and response to sunlight. Britannica
The dermis is primarily composed of which type of tissue?
Dense irregular connective tissue
Adipose tissue
Epithelial tissue
Smooth muscle
The dermis is mainly made of dense irregular connective tissue containing collagen and elastin fibers, which provide strength and elasticity. It houses blood vessels, nerves, hair follicles, and glands. This arrangement allows the skin to withstand stretching in multiple directions. NCBI
The primary function of sebaceous glands is to secrete:
Sebum
Sweat
Cerumen
Saliva
Sebaceous glands secrete sebum, an oily substance that lubricates hair and skin, preventing dryness and providing a barrier against microbes. Sebum is produced via holocrine secretion when entire cells disintegrate to release lipids. Overactivity can lead to acne formation. DermNet NZ
The hypodermis primarily stores:
Fat
Collagen
Keratin
Melanin
The hypodermis, or subcutaneous layer, is rich in adipose tissue that stores fat for energy, insulation, and cushioning. It anchors the skin to underlying structures and helps regulate body temperature. Its thickness varies by body region and individual. NCBI
Which receptor in the skin is most sensitive to light touch?
Meissner's corpuscle
Pacinian corpuscle
Ruffini ending
Free nerve ending
Meissner's corpuscles are rapidly adapting mechanoreceptors located in dermal papillae, best suited for detecting light touch and low-frequency vibrations. They are especially concentrated in fingertips and lips. Their structure allows for sensitivity to fine tactile stimuli. NCBI
Which layer of the epidermis is found only in thick skin?
Stratum lucidum
Stratum corneum
Stratum granulosum
Stratum basale
The stratum lucidum is a clear, thin layer of dead keratinocytes found only in thick skin areas such as the palms and soles. It lies between the stratum corneum and stratum granulosum and provides extra protection. This layer is absent in thin skin. Britannica
What is the main role of keratin in the skin?
Provide strength and water resistance
Produce pigment
Mediate immune response
Generate heat
Keratin is a fibrous protein produced by keratinocytes that provides mechanical strength and waterproofing to the skin. It forms intermediate filaments within cells, contributing to barrier function. Disorders of keratin can lead to skin fragility. NCBI
Eccrine sweat glands differ from apocrine sweat glands in that eccrine glands:
Secrete via merocrine secretion
Open into hair follicles
Begin functioning at puberty
Produce odorous secretions
Eccrine sweat glands release their watery secretions directly onto the skin surface via merocrine secretion without shedding cellular material. They play a key role in thermoregulation and are active from birth. Apocrine glands, in contrast, open into hair follicles and activate at puberty. NCBI
Which phase of wound healing is characterized by collagen deposition and scar formation?
Remodeling phase
Inflammatory phase
Proliferation phase
Hemostasis
The remodeling phase follows proliferation and involves collagen maturation and reorganization, leading to scar tissue formation. Type III collagen is replaced by stronger type I collagen, and the wound gains tensile strength. This phase can last for months. NCBI
Which cells in the epidermis act as antigen-presenting cells?
Langerhans cells
Melanocytes
Keratinocytes
Merkel cells
Langerhans cells are specialized dendritic cells in the stratum spinosum that capture and process antigens, then migrate to lymph nodes to initiate immune responses. They play a crucial role in skin immunosurveillance. Damage to these cells can impair cutaneous immunity. NCBI
Thick skin is found in all of the following areas except:
Forehead
Palms of hands
Soles of feet
Fingertips
Thick skin, characterized by a stratum lucidum and a very thick stratum corneum, is restricted to the palms, soles, and fingertips. Most other body regions, including the forehead, have thin skin without a stratum lucidum. Britannica
Which protein is primarily responsible for skin elasticity?
Elastin
Collagen type I
Keratin
Fibrillin
Elastin is an elastic protein in the dermal extracellular matrix that allows skin to resume its shape after stretching or contracting. Collagen provides tensile strength, while elastin provides elasticity. Loss of elastin fibers contributes to skin aging and wrinkling. NCBI
Where are Pacinian corpuscles primarily located in the skin?
Hypodermis
Epidermis
Dermal papillae
Basement membrane
Pacinian corpuscles are large, onion-like mechanoreceptors located deep in the hypodermis and some other tissues, where they detect deep pressure and high-frequency vibration. They adapt rapidly to stimuli. NCBI
Melanogenesis occurs in which organelle within melanocytes?
Melanosome
Nucleus
Mitochondrion
Golgi apparatus
Melanosomes are specialized organelles in melanocytes where tyrosinase converts tyrosine into melanin. These melanin-containing vesicles are transferred to keratinocytes. Dysfunction of melanosomes can lead to pigmentation disorders. NCBI
Which vitamin is synthesized by the skin upon exposure to UVB radiation?
Vitamin D
Vitamin A
Vitamin C
Vitamin K
UVB radiation converts 7-dehydrocholesterol in the skin to pre-vitamin D3, which is then transformed into vitamin D3. Vitamin D is essential for calcium homeostasis and bone health. Insufficient UV exposure can lead to deficiency. NCBI
Holocrine secretion is characteristic of which gland type?
Sebaceous gland
Eccrine sweat gland
Apocrine sweat gland
Ceruminous gland
Holocrine secretion involves the release of entire cells that disintegrate to secrete their contents. Sebaceous glands use this method to deliver sebum to hair follicles and skin surface. In contrast, eccrine glands use merocrine secretion. NCBI
Which layer of the dermis is responsible for cleavage (tension) lines in the skin?
Reticular layer
Papillary layer
Hypodermis
Stratum basale
The reticular layer, the deeper portion of the dermis, contains dense bundles of collagen and elastin fibers arranged in parallel, forming cleavage lines. Surgeons use these lines to minimize scarring. The papillary layer is more superficial. NCBI
In psoriasis, which epidermal layer shows the most marked hyperproliferation?
Stratum spinosum
Stratum basale
Stratum corneum
Stratum lucidum
Psoriasis is characterized by rapid keratinocyte proliferation, especially within the stratum spinosum, leading to epidermal thickening and parakeratosis. This hyperproliferation results in scaling plaques. The stratum basale is also active but less so. NCBI
Which of the following is NOT a function of Langerhans cells?
Melanin production
Antigen presentation
Phagocytosis
Initiation of immune response
Langerhans cells are dendritic antigen-presenting cells in the epidermis; they phagocytose pathogens and present antigens to T cells. They do not produce melanin—that function belongs to melanocytes. Disruption leads to immune disorders. NCBI
What type of collagen is most abundant in the dermis?
Type I collagen
Type II collagen
Type III collagen
Type IV collagen
Type I collagen is the predominant collagen in the dermal extracellular matrix, providing tensile strength to skin. Type III collagen is also present but in smaller amounts. Type IV forms the basement membrane. NCBI
Which skin condition results from autoimmune destruction of melanocytes?
Vitiligo
Albinism
Psoriasis
Eczema
Vitiligo is an autoimmune disorder where melanocytes are destroyed, leading to depigmented patches of skin. It differs from albinism, which is a genetic enzyme deficiency. Management focuses on repigmentation therapies. NCBI
Which basement membrane protein anchors basal keratinocytes to the basement membrane?
Laminin
Collagen type IV
Integrin
Fibronectin
Laminin is a key glycoprotein in the basement membrane that binds to integrins on basal keratinocytes and to type IV collagen in the lamina densa, securing the epidermis to the dermis. Mutations can lead to epidermolysis bullosa. NCBI
The conversion of 7-dehydrocholesterol to pre-vitamin D3 occurs primarily in which layer of the skin?
Stratum spinosum
Stratum basale
Stratum corneum
Dermal papillae
UVB radiation penetrates into the epidermis reaching the stratum spinosum and stratum basale, where 7-dehydrocholesterol is converted into pre-vitamin D3. This isomerizes into vitamin D3 before liver and kidney activation. NCBI
Langerhans cells in the epidermis are derived from which precursor?
Monocytes
Fibroblasts
Keratinocytes
Mesenchymal cells
Langerhans cells originate from bone marrow–derived monocytes that migrate into the epidermis and differentiate into antigen-presenting dendritic cells. They play a crucial role in skin immune surveillance. NCBI

Cheat Sheet

  1. Master the Epidermal Strata -

    Understand the five layers of the epidermis - stratum corneum, lucidum, granulosum, spinosum, and basale - using the mnemonic "Come, Let's Get Sun Burned." According to Gray's Anatomy, memorizing this hierarchy is a staple for any integumentary quiz or integumentary system exam question. Regularly test yourself with sample integumentary practice test items to reinforce these layers in a questions about the integumentary system format.

  2. Differentiating Sweat Gland Types -

    Eccrine glands regulate body temperature through watery secretion while apocrine glands, found in axillae and groin, release lipid-rich sweat tied to emotional stimuli. The American Academy of Dermatology notes that eccrine activity peaks in palms and soles, a fact often quizzed on integumentary system quizzes. Try drawing a simple diagram labeling each gland's location to cement this concept for your next integumentary quiz.

  3. Melanin Synthesis Pathway -

    Melanocytes in the stratum basale convert tyrosine to DOPA via tyrosinase, ultimately producing melanin that shields DNA from UV damage. This enzyme-driven reaction, detailed in peer-reviewed dermatology journals, is central for understanding skin pigmentation questions about the integumentary system. A quick tip: remember "Tyrosinase Tackles Tyrosine" to recall the enzyme's role on your integumentary practice test.

  4. Barrier Function of the Stratum Corneum -

    The "brick-and-mortar" model describes corneocytes as bricks and intercellular lipids as mortar, forming a waterproof barrier that prevents transepidermal water loss. Studies from the National Institute of Arthritis and Musculoskeletal and Skin Diseases emphasize ceramides' role in maintaining this barrier, a high-yield topic on any integumentary system exam. Sketching this model helps you visualize and ace those integumentary system quizzes.

  5. Phases of Wound Healing -

    Wound repair occurs in four phases - Hemostasis, Inflammation, Proliferation, and Remodeling - often recalled by the acronym "H I P R." The Journal of Dermatological Science highlights growth factors like PDGF in the proliferation phase, a concept that frequently appears in integumentary quiz questions. Create flashcards for each phase to boost confidence and accuracy on your next practice test.
