scapula exam 2 review

What is the subscapular fossa?

It is a concavity on the scapula that matches the curvature of the thoracic spine.

What does the supraspinatus fossa accommodate?

The supraspinatus muscle, located above the spine of the scapula.

What is the infraspinatus fossa?

It is an area below the spine of the scapula that houses the infraspinatus muscle.

What is the glenoid cavity?

It is where the humerus articulates with the scapula, forming the glenohumeral joint.

What does the term 'acromion process' refer to?

It is the larger posterior process of the scapula, also known as the shoulder blade.

What is the meaning of 'coracoid process'?

It refers to a structure on the scapula resembling a crow's beak.

What is the axillary border of the scapula?

It is the lateral aspect along which the armpit is located.

What makes up the trochlea on the humerus?

It is a pulley-like structure that fits into the u-shaped notch of the ulna.

What is the capitulum?

It is a rounded structure on the distal end of the humerus that articulates with the radial head.

What articulates with the coronoid fossa?

The coronoid process of the ulna fits into the coronoid fossa of the humerus.

What is located in the olecranon fossa?

The olecranon process of the ulna fits into this area when the arm is extended.

What are epicondyles?

Small bony projections adjacent to the major articular surfaces on the humerus for ligament attachment.

What does the radial notch accommodate?

It is a notch on the ulna that allows the radial head to sit and move.

What attaches to the radial tuberosity?

The biceps brachii muscle, helping with arm flexion.

How many carpal bones are there?

There are eight carpal bones in total.

What are the primary bones of the shoulder girdle?

The scapula and humerus.

What movement does the deltoid muscle assist with?

It aids in the abduction of the humerus.

What is the primary function of the biceps brachii muscle?

Flexion of the elbow and supination of the forearm.

What anatomical structure serves as the attachment for arm muscles to the humerus?

The deltoid tubercle.

Why is the humerus described as having a 'trochlear' structure?

Because it operates like a pulley for the ulna during elbow movement.

What is notable about the medial and lateral epicondyles of the humerus?

They are bony landmarks for ligament attachment on either side of the humeral joints.
