Shoulder Bone Anatomy Quiz

The prominent bony projection on the scapula that forms the highest point of the shoulder

The posterior view shows the back side of the scapula, with the spine and acromion visible.

The coracoid process is a hook-like projection located at the top and front of the scapula.

The scapula articulates with the humerus (arm bone) at the glenohumeral joint, and with the clavicle (collarbone) at the acromioclavicular joint.

There may be a misinterpretation or missing information about the muscle insertion. The exact muscle needs to be identified for a complete answer.

The humerus, the bone of the upper arm, has a diaphysis (shaft) with three faces (posterior, anterior, and medial), and a groove on the anterior face. It also has three protrusions on the upper extremity, and two fossae (depressions) on the lower extremity.

The muscles that DO insert on the medial epicondyle of the humerus are: the pronator teres (round pronator), flexor carpi radialis (radial flexor muscle of the wrist), flexor carpi ulnaris (ulnar flexor muscle of the wrist), and palmaris longus (long palmaris).

The ulnar extensor muscle of the wrist allows for adduction (movement towards the midline), and terminates at the distal end of the dorsal side of the 5th metacarpal bone.

The coronoid fossa is a depression located on the anterior surface of the humerus, the bone in the upper arm.

The point of the instrument articulates with the humerus and the radius.

The trochlear notch is a part of the ulna bone, it is the part that fits into the trochlea of the humerus, creating a hinge joint, allowing for flexion and extension of the elbow.

The supinator muscle inserts on the lateral side of the radius.

External Rotation

The shoulder and elbow joints are involved in this movement. They are both synovial joints. The shoulder is a ball-and-socket (glenohumeral) joint, and the elbow is primarily a hinge joint formed by the humerus, ulna, and radius.

The bony projection on the lower end of the radius, which forms the outer part of the wrist joint.

A view of the body or a bone from the side.

The deep notch in the upper part of the ulna, where the humerus (upper arm bone) fits.

The process of determining the orientation of a bone or body part by its anatomical features.

The process of labeling specific anatomical features on a bone.

The radial tuberosity is a bony prominence found on the upper end of the radius bone. It serves as an attachment point for the biceps brachii muscle, responsible for flexing the elbow.

The anconeus muscle is a small triangular muscle located on the posterior aspect of the elbow joint. It assists in extending the elbow and stabilizing the elbow joint.

The infraspinatus muscle originates on the infraspinous fossa of the scapula and inserts on the greater tubercle of the humerus. It is responsible for external rotation of the shoulder joint.

The point § represents the glenohumeral joint, the articulation point between the head of the humerus (arm bone) and the glenoid fossa of the scapula (shoulder blade). This joint allows for a wide range of movement in the shoulder.

The movement of the forearm that rotates the hand so that the palm faces downwards.

The radio-ulnar joint is formed by the articulation between the radius and ulna bones in the forearm. It allows for pronation and supination movements, rotating the hand from palm up to palm down and vice versa.

The trochlear joint is a type of hinge joint. It allows for movement in one plane, like a door hinge. In the upper limb, the trochlear joint is found between the humerus (upper arm bone) and the ulna (bone on the pinky side of forearm). It allows for flexion and extension of the elbow.

The forearm is the region of the upper limb located between the elbow and wrist. It contains the radius and ulna bones, responsible for movements like pronation and supination.

The petit rond muscle is a small, round muscle located in the shoulder region. It assists in external rotation and adduction of the arm.

A posterior view of the arm shows the back side of the arm, with the muscles on the back of the arm visible.

The medial side of the arm is closer to the midline of the body, while the lateral side is farther away.

The huméro-postérieur muscle is located on the back of the arm, and its name indicates its position.

Muscle '2' inserts on the upper arm bone (humerus) and is located on the back of the arm.

Muscle '3' originates from the head of the humerus, the top part of the upper arm bone.

The movement of the forearm, rotating the hand so that the palm faces downwards.

The joint between the radius and ulna, allowing rotation of the forearm for pronation and supination.

The medial side of the body is closer to the midline, while the lateral side is further away.

Muscle 2 originates from the humerus and inserts on the humerus.

The action of the bicep muscle, bending the arm at the elbow.

The bony projection on the lower end of the radius, forming part of the wrist joint.

Muscle 3 originates from the head of the humerus.

The movement of the forearm, rotating the hand so that the palm faces upwards.

Muscle 1 is located on the posterior side of the humerus.

The teres major, supraspinatus, and subscapularis muscles all insert on the greater tubercle of the humerus. The teres minor does not.

The infraspinatus and teres minor muscles cause lateral rotation of the shoulder.

The conoid tubercle is attached to the clavicle, which connects the shoulder blade to the sternum.

The trochlear notch is located on the ulna, which forms part of the elbow joint with the humerus.
