teres major and minor

19
Q

What are the two glenoid attachments?

A

supraglengoid tubercle and infraglenoid tubercle. They are the long heads of the biceps brachii and tricepts brachii. They are found attached to the scapula.

20
Q

The rotator cuff of the scapula contains what regions?

A

subscapular fossa (anterior), supraspinatus, infraspinatus, teres minor (lateral/axillary)

21
Q

Where is the surgical neck located?

A

Near the head of the humerus

22
Q

Where is the trochlea located?

A

On the inferior end of the humerus.

23
Q

What three regions are found on the superior & anterior side of the humerus?

A

greater tubercle, lesser tubercle and inter-tubercular groove. PIC

24
Q

What two regions are found on the anterior inferior side of the humerus?

A

capitulum and trochlea. PIC

25
Q

What does the head of the humerus articulate with?

A

glenoid of the scapula.

26
Q

What part of the scapula contains a hole in which the humerus attaches to?

A

glenoid cavity

27
Q

What attches to the lesser tubercle?

A

subscapularis
