Q

Where does the seratis anterior originate?

A

upper 8 or 9 ribs

24
Q

Where does the seratus anterior insert?

A

the medial border of the scapula

25
Q

What 2 movements does the seratus anterior do?

A
  • rotates the scapula upwards allowing the arm to be raised over 90 degrees
  • protracts the scapula (boxing muscle)
26
Q

How does the seratus anterior stabilise the shoulder?

A

3rd to 5th ribs

28
Q

Where does pectoralis minor insert?

A

the coracoid process of the scapula

29
Q

How does the pectoralis minor stabilse the scapula?

A

by pulling it downward and anteriorly against the thoracic

30

A

smallest
scapula
abduction

33
Q

How does the supraspinatus help stabilise the shoulder?

A

By keeping the head of the humerus firmly against the glenoid cavity

internal rotation
humerus
stabiliser

Teres Major
adduct
medially
glenohumeral
humerus

A

crutches
transferring

44
Q

How does Teres Major move the upper limb? (3)

A

it works with Latissumus Dorsi to extend, adduct and internally rotate the shoulder.

45
Q

Teres major is also known as little _______. It helps with rowing, swimming and tennis.

A

lats

46
Q

Where does the Coracobrachialis extend from?

A

the coracoid process of the scapula to the shaft of the humerus

47
Q

How does the coracobrachialis move the upper limb? (2)

A

it flexes and adducts the shoulder (glenohumeral joint)

48
Q

The coracobrachialis is the antagonist to which muscle? why?
