Name the 2 bones of the shoulder girdle
Scapula and Clavicle
Describe the acromioclavicular joint
Where the coracoid process and posterior acromion form a joint with the clavicle
Name the 4 regions of the upper limb
Arm, forearm, wrist, and hand
of bones in the arm
1, the humerus
of bones in the forearm
2, lateral radius and medial ulna
Glenoid Cavity
a lateral depression that forms the shoulder joint with the humerus, two projections that form the AC joint
Lateral forearm bone
Radius
Medial forearm bone
Ulna
Proximal radioulnar joint
a radial head articulates with the ulna
Distal radioulnar joint
the radius and ulna articulate at their distal ends, both bones have a styloid process
of wrist bones
8 short bones
Metacarpals
5 long bones in the hand that articulate distally with the fingers
Phalanges
14 long bones that form the fingers
Numbering system of bones
numbering starts with the thumb being #1
Names of phalanges
- tip: distal
- intermediate: middle
- proximal: bottom
Digit with 2 phalanges
thumb, proximal and distal phalanx
Digits with 3 phalanges
second-fifth digits,
- proximal
- intermediate
- distal
Shapes of the bones of the upper limb
long bones
3 functions of the pelvic girdle
- connects lower limbs to the trunk
- supports the pelvic organs
- transmits the weight of the trunk to the legs
of coxal (hip) bones that make up the pelvic girdle
2, hemipelvis bones
3 fused bones that make up each coxal bone
- ilium
- ischium
- pubis
Pubis Symphysis
the fibrocartilage pad where the two pubic bones meet
Male pelvis
- narrower, heart shaped
- narrow angle
- closer together
- inverted
- curved anteriorly, less movable
Female Pelvis
- wider and oval shaped
- wide angle
- farther apart
- everted
- straighter, more movable
