Q

What are synovial joints?

A

fluid-filled joint cavity, results in increased flexibility between hyaline covered articular surfaces. All synovial joints are diarthroses.

28
Q

Articular cartilage is mostly __ cartilage

29
Q

An outer layer of fibrous tissue that is continuous with the periosteum of the related bones and an inner synovial membrane which covers all except the articular cartilage is called what?

A

articular capsule

30
Q

Fribrocartilaginous ___ ___ can be found within the cavity or between two cavities to improve the surface interactions or absorb forces

A

articular discs

31
Q

Give an example for each mechanical classification of a synovial joint:
uniaxial
biaxial
multiaxial

A

uniaxial: elbow
biaxial: knuckles
multiaxial: glenohumeral joint

32
Q

The following describes what type of shape classification of synovial joints:
two flat surfaces, allowing gliding/sliding movements

33
Q

The following describes what type of shape classification of synovial joints:
cylindrical end fits into a trough end, allowing uniaxial movements (ex: elbow)

34
Q

The following describes what type of shape classification of synovial joints:
cylindrical end fits into a ring of bone with fibrous support tissue, allowing rotation (atlantoaxial joint for shaking head side to side)

35
Q

The following describes what type of shape classification of synovial joints:
egg-shaped surface with a concave surface, allowing biaxial movements of flexion/extension and abduction/adduction

36
Q

The following describes what type of shape classification of synovial joints:
saddle-shaped convex and concave surfaces yielding biaxial movements, as condyloid joints (ex: carpometacarpal joint at base of thumb).

37
Q

The following describes what type of shape classification of synovial joints:
a sphere in a concave socket yielding multiaxial movements (ex: shoulder and hip)

A

ball and socket

38
Q

Define Hilton’s Law

A

a joint is innervated by branches of the nerves that innervate the muscles which move the joint. These articular nerves are used in transmitting pain, proprioceptive (joint position) information, and for innervating adjacent vasculature (vasomotor function)

39
Q

40
Q

Why type of epithelium makes up the epidermis?

A

keratinized, stratified squamous

The dermis is the vascular, deeper layer of the skin and is formed by what?

A

dense connective tissue

Where are high densities of skin ligaments found?

A

in the palms of hands, soles of feet

43

44
Q

Deep fascia has thickenings near joints called ____, which act as pulleys for tendons running deeply

A

Q

True or false?

muscles shorten to produce force

54
Q

Describe iostonic contractions

A

muscle tension is greater or lesser than external forces resulting in an associated movement

55
Q

____ contractions exist when the muscle tension is greater than the opposing forces, resulting in overall muscle shortening and subsequent skeletal movement

A

concentric

56
Q

____ contractions exist when the muscle tension is less than the opposing forces, resulting in overall muscle lengthening and subsequent skeletal movement

Q

A muscle which isometrically contracts to stabilize the origin of the prime mover is a ____

58
Q

Arteries branch while veins converge, forming ____

A

tributaries

59
