consists of R & L clavicles and R & L scapulae, supports the upper appendages
consists of R&L coxal bones and the sacrum, supports the lower appendages
2 irregular, triangular bones in the dorsal thorax
"shoulderblade" a long, sharp process, easily palpated
"point of the shoulder" the acromial ends of the clavicles articulates here
helps anchor the bicep muscle, anterior, superior process
shallow depression, articulates with humerus, the shallowness of this cavity makes this an easily dislocated joint
S - shaped slender, articulate with the acromion process of the scapulae and with the sternum. S shape makes it vulnerable to compression from both ends
arm, typical long bone
rounded process at proximal end which artics. with the glenoid cavity of the scapula.
GREATER & LESSER TUBERCLES
near the head are attachment points for several muscles. A large tendon runs along a groove between them.
region where proximal epiphysis joins diaphysis. This is the most commonly fractured area.
elevated area on lateral shaft. Site of attachment for the deltoid muscle.
CAPITULUM & TROCHLEA
on anterior, distal end surface, serve as articulating surfaces for the radius and ulna.
on posterior surface marks the pathof the large radial nerve.
on posterior surface, distal end artics. with ulna.
radius and ulna are held together lengthwise by a flexible...
longer than the radius
posterior surface of proximal end. Forms the point of the elbow.
on the anterior surface of the proximal end, inside the olecranon process, this deep depression fits over the trochlea of the humerus.
at the distal end, unlike other long bones
near the thumb
proximal end, spool shaped articulates with humerus in such a way that it can rotate around it without getting disconneted.
distal to head, anchors the bicep muscle
8 bones that glide over each other.
5 bones form palm of hand
all the bones of the fingers
bones slide across each other, carpals
bending parts to decrease the joint angle
straightening parts to increase the joint angle
lifiting foot toward shin
pointing the toes
movement of a limb away from the midline
movement of a limb toward the midline
turning movement of a bone around its long axis
moving a part so its end follows a circular path
turning hand so palm faces forward
turning hand so palm faces backward
sole of foot turns inward
sole of foot turns outward
thrusting of chin forward
pulling chin in toward chest.
lifting a part, ex. shrugging shoulders
lowering a part, ex. bringing shoulders back down
touching thumb to other fingers
BALL AND SOCKET
ball shaped head of one bone fits into a cup shaped socket on another, ex. shoulder - hip
gliding joints ex. carpals
motion is along a single plane, permits extension and flexion only. ex. elbow, knee, finger joints
joint between C-1 & C-2, also radio-ulnar joint
all articulating surfaces are oval. ex. wrist joints, knuckle joints
