Q

bone functions:

A

1, movement levers
2, primary storage site for minerals (Ca, P)
3, location for blood cell info
4, serve to protect internal organs

2
Q

typical person has … bones

A

206

3
Q
axial skeleton - 
function -
A

skull, vertebral column, sternum, ribs;

- protect important internal organs (brain, heart, lungs) and offer sites for the skeletal muscle attachments

4
Q
appendicular skeleton - 
function -
A
  • upper and lower limbs;
  • rotation of these bones around joints responsible for the movements associated with the exercise (lifting, running, throwing, kicking, striking)
5
Q

general bone characteristics :

A
  • complex, living dynamic tissue
6
Q

2 types of bones

A

1) cortical/ compact

2) cancellous/trabecular

7
Q

cortical bone -

A

hard, dense found in outer layer of long bones in arms and legs

8
Q

cancellous bone/spongy -

A
  • less dense found in the interior area of the long bone (vertebrae and head of the femur)
  • site of the hematopoiesis (blood cell formation)
9
Q

2 minerals that help form the body’s bones

A

calcium and phosphorus

10
Q

osteoporosis

A

‘porous bones’, condition when bones are weak and brittle; susceptible to breaking especially in spine and hip

11
Q

Wolff’s law

A

‘bone adapts to exercise by increasing in mass and strength. response to stresses placed on it’

12
Q

exercise to increase bone mineral density

A

weight-bearing running, walking, resistance training especially eccentric loading.

13
Q

tendons are formed from..

A

inelastic protein collagen

14
Q

ligaments are formed from..

A

collagen and elastic protein elastin which allows bones to stretch and stabilise the joint why giving it some mobility.
