A

provides basic shape
provides support for the body
allows the muscular system to produce movement-locomotion
protection of vital organs

A
axial skeleton:
head
neck
trunk
appendicular skeleton:
limbs
pectoral & pelvic girdle
3
Q

describe cartilage

A

resilient, semirigid CT
in areas for flexibility
articular cartilage reduces friction
avascular

4
Q

A
support 
protection
mechanical basis (leverage/locomotion)
storage
new cells
5

A

compact
spongy
amount of solid matter and size of space

where tendons, ligaments or fascia is attached

where arteries lie adjacent

9
Q

what are bone formations?

A

passage of a tendon to improve leverage

hip & knee joints most stable
ankle unstable
tendency for body to fall forward

11
