Q

What must happen in order for the shoulder to abduct fully and what helps accomplish this?

A

rotation of the glenoid fossa; the serratus anterior helps accomplish this by abducting the scapula, rotating the inferior angle of the scapula such that the glenoid fossa rotates and allows for full abduction of the shoulder

Four key attachment sites = greater tubercle, lesser tubercle, intertubercle sulcus, deltoid tuberosity

Greater tubercle = supraspinatus, infraspinatus, teres minor

Lesser tubercle = subscapularis

Intertubercle sulcus = teres major, latissimus dorsi

Deltoid tuberosity = deltoid

only bony attachment of the upper limib with the axial skeleton

24
Q

what innervates posteiror belly of digastric?

A

facial nerve (VII)

25
Q

1

A

corpus cavernosa

26
Q

pterygomaxillary fissure

A

space between pterygoid plates and maxilla anteirorly

communication between the infratemporal fossa and the pterygopalatine fossa

27
Q

what inserts on the coronoid process of the ulna?

A

bracialis

28
Q
A
  1. Thenar compartment
  2. Central compartment
  3. Hyothenar compartment
29
Q
A
30
Q

What is the only muscle that inserts on the lesser trochanter of the femur?

A

Iliopsoas

31
Q

why would pathology of pancreatic neck cause enlarged spleen?

A

compression of splenic vein

32
Q

acromion process

A

extension of the lateral part of scapular spine

33
Q

Identify

A

mandible

34
Q

Which muscles abduct the shoulder and in what order do they take action?

A

Supraspinatus initiates the movement Deltoid continues the movement The serratus anterior and trapezius allow for glenoid rotation that completes the abduction of the shoulder

35
Q

What are the three things that insert on the coracoid?

A

coracobrachialis, pec minor, short arm of the bicep

36
Q

what innervates anterior belly of digastric?

A

V3- mandibular division of trigeminal nerve

(specifically, the infeiror alveolar branch which gives off its own branch called the nerve to the mylohyoid)

37
Q

fxn of lumbricals

A

simulataneous mp flexion ip extention; innervated by median nerve

38
Q

direct visceral branches

A

postganglionic sympathetic fibers that descend through the cardiac plexus to distribute along coronary arteries

39
Q

what is in medial umbilical folds

A

obliterated uterine artery

40
Q

List the boundaries of the quadrangular space and name two things that pass through???

A

Boundaries

  • subscapularis
  • teres major
  • surgical neck of humerus
  • long head of triceps

Structures that pass through

  • axillary nerve
  • posteiror humeral cirucmflex
41
Q

Interossi of the hand

A

Palmar interossi = ADduct (#1,3,4)

Dorsal interossi = ABduct (#1,2,2,3)

42
Q

what is in the pterygopalatine fossa

A

the pterygopalatine ganglion; this is important because the greater petrosal goes through this after traveling through the pterygoid canal, to get to the lacrimal gland for secretomotor fxn

medial to infratemporal fossa

43
Q

List the 8 Thumb Muscles and the corresponding nerve that innervates them

A
  1. Abductor pollicis brevis = recurrent motor branch of the median nerve
  2. Opponens pollicis = recurrent motor branch of the median nerve
  3. Flexor pollicis brevis = recurrent motor branch of the median nerve
  4. Extensor pollicis longus = radial nerve
  5. Extensor pollicis brevis = radial nerve
  6. Abductor pollicis longus = radial nerve
  7. Flexor pollicis longus = median nerve
  8. Adductor pollicis = ulnar
44
Q

Does scapula have a bony attachment to axial skeleton?

A

No!

45
Q

Name the parts of this bone

A
  1. greater tuberosity
  2. anatomical neck
  3. deltoid tuberosity
  4. lateral
  5. medial
  6. trochlea
  7. radial tuberosity = this is where the radial nerve and brachial artery pass next to the bone; this is why a middle fracture of the humerus can injure the radial nerve and brachial artery
  8. olecronon process
46
Q

A

The cricothyroid is innervated by the external branch of the superior laryngeal nerve, which is a branch of the vagus nerve

median umbilical folds

lateral umbilical folds

48
Q

What comes out of the suprascapular notch

50
Q

whats in the round ligament of the liver

A
