What is the name of the long bone in the upper arm?
Radius
Humerus
Scapula
Ulna
The humerus is the long bone in the upper arm that connects the shoulder to the elbow. This makes it the correct answer.
Which joint is primarily involved in elbow flexion and extension?
Knee joint
Hip joint
Shoulder joint
Humeroulnar joint
The elbow joint complex mainly involves the humeroulnar joint, which functions as a hinge facilitating flexion and extension. Therefore, it is the correct choice.
Which bone is located on the forearm that forms part of the elbow joint?
Patella
Clavicle
Fibula
Ulna
The ulna is the medial bone of the forearm and articulates with the humerus at the elbow. This makes it the correct option.
Which structure connects muscle to bone?
Tendon
Bursa
Cartilage
Ligament
Tendons attach muscles to bones, enabling the transfer of force during movement. This is why 'Tendon' is the correct answer.
Which part of the humerus is commonly referenced when naming a fracture near the upper part of the bone?
Greater tubercle
Capitulum
Surgical neck
Olecranon
The surgical neck of the humerus is a well-known site for fractures, particularly in older individuals. This makes it the correct answer to the question.
Which two joints make up the elbow complex?
Radioulnar and hip
Acromioclavicular and sternoclavicular
Humeroulnar and humeroradial
Shoulder and wrist
The elbow joint complex is composed of both the humeroulnar and humeroradial joints, which allow for flexion and extension. This dual structure is why the correct answer is as stated.
What is the function of the olecranon process?
It serves as the lever for the triceps muscle
It articulates with the scapula
It provides attachment for biceps
It protects the radial nerve
The olecranon process, located on the ulna, acts as a lever for the triceps muscle during elbow extension. Its role in facilitating forceful extension is why it is the correct answer.
What is the anatomical term for the bony prominence on the lateral side of the elbow seen on the distal humerus?
Trochlea
Lateral epicondyle
Intercondylar notch
Medial epicondyle
The lateral epicondyle is the bony prominence on the outer portion of the distal humerus, serving as an important muscle attachment site. This makes it the correct option.
Which muscle's tendon attaches to the medial epicondyle of the humerus?
Triceps brachii
Flexor carpi radialis
Deltoid
Biceps brachii
The flexor carpi radialis originates from the medial epicondyle and is involved in wrist flexion. Its anatomical attachment confirms it as the correct answer.
The head of the humerus articulates with which structure?
Radial notch
Olecranon
Ulnar notch
Glenoid cavity
The head of the humerus fits into the glenoid cavity of the scapula to form the shoulder joint. This ball-and-socket mechanism is why the glenoid cavity is the correct answer.
Which nerve is most commonly at risk of injury around the surgical neck of the humerus?
Ulnar nerve
Axillary nerve
Median nerve
Radial nerve
The axillary nerve courses near the surgical neck of the humerus and is susceptible to damage if a fracture occurs in this region. This makes it the anatomically correct answer.
Which ligament is primarily responsible for stabilizing the radial head during forearm rotation?
Interosseous membrane
Radial collateral ligament
Ulnar collateral ligament
Annular ligament
The annular ligament encircles the head of the radius, keeping it in alignment with the ulna during pronation and supination. Its stabilizing role makes it the correct answer.
What type of joint is found between the humerus and ulna at the elbow?
Ball and socket joint
Pivot joint
Saddle joint
Hinge joint
The humeroulnar joint, a major component of the elbow, is a hinge joint allowing primarily for flexion and extension. This description confirms it as the correct answer.
Which bone of the forearm forms the primary articulation with the capitulum of the humerus?
Scapula
Radius
Ulna
Humerus
The capitulum of the humerus articulates mainly with the head of the radius, facilitating elbow motion. Therefore, the radius is the correct choice.
Which muscle is primarily responsible for elbow flexion?
Triceps brachii
Deltoid
Latissimus dorsi
Biceps brachii
The biceps brachii is the main muscle involved in elbow flexion, playing a key role in bending the arm. This function makes it the correct answer.
During a complex elbow fracture involving the distal humerus, which muscle's attachment might be most compromised due to its origin at the lateral epicondyle?
Brachialis
Pectoralis major
Extensor carpi radialis brevis
Serratus anterior
The extensor carpi radialis brevis originates from the lateral epicondyle of the humerus. A fracture in this area can interfere with its attachment and function, making it the correct answer.
A fracture of the surgical neck of the humerus may lead to weakness in which movement due to nerve injury?
Wrist flexion
Forearm pronation
Elbow extension
Shoulder abduction
Injury to the axillary nerve at the surgical neck affects the deltoid muscle, which is crucial for shoulder abduction. This is why shoulder abduction weakness is the correct outcome.
Which anatomical structure contributes significantly to the stability of the elbow by preventing posterior displacement of the ulna?
Lateral epicondyle
Olecranon
Radial head
Coronoid process
The coronoid process of the ulna acts as a bony block that prevents the ulna from displacing posteriorly relative to the humerus. This key stabilizing role makes it the correct answer.
In the context of elbow injuries, which ligament injury is most commonly associated with posterolateral rotatory instability?
Anterior cruciate ligament
Deltoid ligament
Medial collateral ligament
Lateral collateral ligament
Damage to the lateral collateral ligament complex can lead to posterolateral rotatory instability of the elbow. Its critical role in joint stability confirms it as the correct option.
Which of the following best describes the role of the interosseous membrane in the forearm?
It primarily facilitates independent movement of the two bones
It stabilizes the radius and ulna allowing force transmission during grip
It protects the brachial artery
It directly forms the elbow joint
The interosseous membrane serves as a fibrous connection between the radius and ulna, stabilizing them and assisting in force transmission during gripping activities. This makes it the best description among the options.

Humerus & Elbow Anatomy Cheat Sheet

  1. Longest Upper Limb Bone - The humerus is the superstar bone of your arm, spanning from shoulder to elbow and giving you that swing power. At its top, you'll find the head, anatomical neck, and two tubercles - greater and lesser - each busy hosting muscle attachments to help you flex and lift. kenhub.com Anatomy of the Humerus
  2. Greater Tubercle Hosts Rotator Cuff Friends - Think of the greater tubercle as a cozy apartment block for three rotator cuff tenants: supraspinatus, infraspinatus, and teres minor. Remember "Sally and Ingrid Teach Maths" to keep them in check and ace your muscle mapping. kenhub.com Greater Tubercle Details
  3. Lesser Tubercle's Solo Star - The lesser tubercle is home to the subscapularis muscle, completing the rotator cuff quartet and powering internal rotation of your shoulder. Its prime location ensures stability when you throw, push, or even scratch your back! kenhub.com Lesser Tubercle Insights
  4. Bicipital Groove Groove - Nestled between the two tubercles, the intertubercular sulcus (aka bicipital groove) acts like a snug tunnel for the long head of your biceps tendon. Think of it as the VIP track guiding that tendon smoothly from shoulder to forearm. kenhub.com Bicipital Groove Explained
  5. Elbow Articulations - Down at the distal end, the trochlea partners with the ulna, and the capitulum buddies up with the radius, forming your elbow joint's dynamic duo. Together, they let you flex, extend, and flex again - perfect for high-fives and arm wrestling! teachmeanatomy.info Distal Humerus Anatomy
  6. Olecranon Fossa Fit - Flip the humerus around and you'll find the olecranon fossa, a deep notch that welcomes the olecranon process of your ulna every time you straighten your arm. Without this groove, elbow extension would be a clunky affair. Wikipedia Olecranon Fossa
  7. Tri-Joint Elbow System - Your elbow is actually three joints in one: ulnohumeral (hinge), radiohumeral (pivot), and proximal radioulnar (twist). This triple-threat combo lets you flex, extend, pronate, and supinate - fancy words for turning your palm up or down. Orthobullets Elbow Biomechanics
  8. Ligament Landmarks - Medially, the ulnar collateral ligament stops you from flapping outward; laterally, the radial collateral ligament keeps you from bowing inward. These elastic bands are your elbow's security guards, maintaining stability whether you're throwing a curveball or lifting groceries. Orthobullets Ligament Breakdown
  9. Carrying Angle Quirk - When you extend your arm and supinate your palm, a small angle appears between arm and forearm - 5 - 10° in dudes, 10 - 15° in ladies. This "carrying angle" helps you carry objects without bumping your hips and gives your arms a natural flare. Orthobullets Carrying Angle
  10. Axillary Nerve's Roundabout - Wrapping around the surgical neck of the humerus, the axillary nerve is the VIP cable powering your deltoid and teres minor. If it gets nicked, shoulder abduction takes a hit - so keep that nerve happy and protected! NCBI Axillary Nerve Anatomy
