Kinesiology unit 3 wrist and bones

How many bones in wrist and hand including radius and ulna

29

how many carpal bones in each hand

8

How many metacarpal bones are there?

5 in each hand

How many phalanxes are there

14, 3 for each phalange except thumb has 2

Connects phalanxes together

Interphalegal joints

sesamoid bones are capsulated by a

Tendon

Sesamoid changes what

Angle pull

Which carpal bones articulate with the distal radius

Scaphoid and lunate

Most often fractured carpal bone

Scaphoid

most often dislocated carpal bone

Lunate

Thenar muscle

Fatty area by thumb

Hypothenar

Fatty area by pinky

Retinaculum

Tissue that holds other tissue in place

Which bones are articulated the most

Scaphoid lunate and radius

Wrist has more adduction than abduction because of

Stylioid process

Wrist Flexion/Extension

65-90

wrist abduction

15-25

wrist adduction

25 to 45 degrees

what type of joint is the elbow joint?

Ginglymus or hingetype joint

elbow joint only allows for

flextion and exetntion

the two interrelated joints of the elbow

Humeroulnar (more stable) and Radio humeral

Collateral ligaments reduce or prevent

frontal plane motion
