Q

what is the outer surface of bone covered in

A

periosteum

17
Q

what is the periosteum

A

it isolates the bone from surrounding tissues and plays a role in the growth n repair of bones

18
Q

what is the inner surface of bone called

A

endosteum

19
Q

what are the 2 types of bone tissue

A
  1. compact bone tissue
  2. spongy bone tissue
20
Q

what is compact bone tissue (characteristics and function)

A

is hard and dense bc it has few spaces within its components
forms the outer layer of all bones + constitutes the bulk of the diaphysis of long bones

21
Q

what is compact bone tissue organised into

A

many cylinderal units called osteons

22
Q

what runs through the haversian canal

A

blood vessels, nerves, lymphatic vessels
