A

subscapularis

27
Q

What does the Intertubercular Sulcus contain?

A

long head of biceps brachii

28
Q

This is located in the middle of the humeral shaft and serves as an attachment of the deltoid muscle?

A

Deltiod tuberosity

29
Q

On the distal end of the humerus, the anterior surface is known as (?) on the shaft and ends in the (?)

Sharp lateral supracondylar ridge

lateral epicondyle

30
Q

The medial supracondylar ridge terminates where?

A

@ the medial epicondyle

31
Q

this has an indentation and it is medial to the capitulum (spindal shaped)

A

Trochlea

33
Q

This lies above the capitulum & contains part of radius during flexion?

A

radial fossa

34
Q

this lies above the trochlea & recieves the ulnar coronoid process during flexion?

A

35
Q

this is a large depression on the posterior distal end of the humerus that recieves the olecranon process of ulna when forearm extends?

A

Olecranon fossa

36
Q

Which forearm bone forms the medial and lateral borders of the forearm?

A

Medial= Ulna

Lateral= Radius

37
Q

What forms the prominence of the elbow and which bone of the forearm is it on?

A

Olecranon process

on the proximal portion of the Ulna

38
Q

This is an anterior projection @ the proximal end of the Ulna

A

Coronoid process

39
Q

this is a large curved area that forms the elbow joint, its formation is due to the olecron & coronoid process recieving the trochlea of the humerus
