shaft of long bone

18
Q

epiphysis

A

wide end of bone. covered with cartilage. proximal and distal

19
Q

foramen

A

opening in bone for blood vessels, nerves, and ligaments to pass

20
Q

process

A

normal projection on surface of bone that serves as attachment point for muscles and tendons

21

inflexible layers of dense connective tissue. hold bones tightly together. not movable. only movable in infants.

22
Q

fontanelles

A

soft spots. on skull of newborn. help with birth

23
Q

cartilagious joints

A

allow slight movement. bones connected entirely by cartilage. (where ribs connect to sternum)

24
Q

Q

synovial capsule

A

outermost layer of strong fibrous tissue

27
Q

synovial membrane

A

lines capsule and secretes synovial fluid

28
Q

synovial fluid

A

flows in synovial cavity. lubricant to make movements smooth.

29
Q

ligaments

A

bands of fibrous tissue that form joints. bone to bone or bone to cartilage

30
Q

bursa

A

fibrous sac that acts as cushion to ease movement in friction areas

31
Q

axial skeleton

A

protects major organs of nervous, resp., and circulatory systems (spine, ribs)

32
Q

Appendicular skeleton
