Q

What is referred to as the “vertebral border?”

A

the medial border of the scapula that runs parallel to the spinous processes of the thoracic vertebra.

17
Q

Which border of the scapula is the thinnest and shortest?

A

the superior border

18
Q

What structure is referred to as the “anatomical neck” of the humerus?

A

the groove circumscribing the head which separates it from the greater and lesser tubercles.

19
Q

The greater/lesser tubercle is at the lateral margin of the humerus?

A

greater

20
Q

The greater/lesser tubercle is at the anterior portion of the bone in relation to the other tubercle.

A

lesser

21
Q

What two bones in the lower arm allow for supination by means of pivoting around each other?

A

radius and ulna

22
Q

The _______ is the stabilizing and longer of the two bones of the forearm.

A

ulna

23
Q

The _____ process and _______ form the walls of the trochlear notch?

A

coronoid process and olecranon

24
Q

The fibers running from the radius run inferiorly and obliquely towards the ulna for what purpose? (what purpose does this serve in relation to forces placed on the wrist?

A

allows for transfer of forces from radius to ulna, and consequently to the humerus.

25
Q

Which two bones of the hand appear first during postnatal ossification?

A

the capitate and hamate

26
Q

The superior angle of the scapula lies at the level of the __ vertebra.

A

T2

27
Q

The inferior angle of the scapula lies at the level of the ___ vertebra.

A

T7

28
Q

More ulnar/radial deviation is possible because of the radius having a longer extension of its styloid process.

A

ulnar. (radius extends out more, allowing more room for ulnar movement.)

29
Q

The weakest part of the clavicle is where?

A

the junction between the medial and lateral thirds

30
Q

A ______ fracture is one where one side of the bone is broken and the other is bent.

A

greenstick

31
Q

The _______ is first long bone to ossify and the last one to be fully formed.

A

clavicle

32
Q

The middle aged and elderly are more susceptible to _______ (what type) fractures of the humerus.

A

avulsion

33
Q

An ________ fracture is the result of one fragment being driven into the spongy bone of the other fragment.

A

impacted fracture

34
Q

A colles fracture occurs by what mechanism?

A

A complete transverse fracture on the distal edge of the radius.

35
Q

The ______ is the most commonly fractured carpal bone?

A

scaphoid

36
Q

Boxer’s fracture occurs where in the hand?

A

the 5th metacarpal

37
Q

subcutaneous tissue contains F_ _?

A

fat

38
Q

deep fascia contains and compartmentalizes what?

A

muscle

39
Q

The fascia of the pectoral region is attached at the ______ and sternum.
