I:Basihyoid

22
Q

Sternothyroideus

A

O:manubrium
I: thyroid cartilage

23
Q

Sternohyoideus and sternothyroideus action

A

pull tongue and larnyx caudally

24
Q

Whats in the carotid sheath?

A

Common carotid artery, vagosympathetic trunk, internal jugular, and tracheal lymphatic trunk

25
Q

2 parts of deltoideus

A

scapular part and acromial part

26
Q

Supraspinatus O and I

A

O: supraspinous fossa
I: greater tubercle of the humerus

27
Q

Supraspinatus action

A

Extend and stabilize shoulder

28
Q

Teres major O&I

A

O: caudal border of scapula
I:teres major tuberostiy

29
Q

Teres major action

A

Flex shoulder, rotate should medially. Prevent lateral rotation of shoulder when weightbearing

30
Q

Triceps Long head O&I

A

O:Caudal border of scapula
I: olecranon tuber

31
Q

Triceps lateral head O&I

A

o: Tricipital line
I: olecranon tuber

32
Q

Triceps accessory head O&I

A

O: neck of the humerus
I: olecranon tuber

33
Q

Triceps medial head O& I

A

O: crest of lesser tubercle of the humerus (near the teres major)
I: olecranon tuber

34
Q

Triceps brachii action

A

to extend the elbow. Long head also flexes shoulder joint

35
Q

Biceps brachii O&I

A

O: supraglenoid tubercle of the scapula
I: ulnar and radial tuberosities

36
Q

Biceps brachii action

A

Flex elbow

37
Q

Where is the transverse humeral retinaculum?

A

goes between greater and lesser tubercle-right across tendon of bicep brachii

38
Q

Flexors of the shoulders

A

Latissmus dorsi, deltoideus, teres major, teres minor, long head of the triceps brachii

DTT is innervated by the axillary nerve-if damage occurs the thoracolumbar nerve that innervates the latissmus dorsi can take over

39
Q

Extensors of the shoulder

A

Supraspinatus, brachiocephalicus

40

biceps brachii, brachialis (musculocutaneous nerve)

41
Q

Extensors of the elbox

A

Triceps, anconeus (Radial nerve)

42
Q

Extensors of the carpus

43
Q

Flexors of the carpus

A

Flexor carpii ulnaris, SDF, DDF, flexor carpii radialis

44
Q

Suprascapular nerve innervates…

A

supraspinatus and infraspinatus. damage causes sweeney

45
Q

Axilllary nerve innervates

A

Deltoideus, teres major, teres minor

46
Q

Musculocutaneous nerve innervates

A

Biceps brachii, brachialis, coracobrachialis

47
Q

Radial nerve innervates

A

Triceps brachii, anconeus, tensor fasciae antebrachii and ECLU
Splits up into 2: superficial and deep branch
Superficial branch: sensory
Deep branch: motor

48
Q

Ulnar and median nerve innervates…

A

Flexors of the carpus,
