parts of long bone

Question 1

what is the diaphysis

Answer 1

this is the shaft of the long bone with ecloses the medullary cavity

Question 2

what is the epiphysis

Answer 2

this is the ends of long bone formed out of cancellous bone covered in a thin layer of compact bone
it articulates other bones to form joints and it is covered in a layer of cartilage to absorb shock and reduce friction

Question 3

what is the distal and proximal epiphysis

Answer 3

the proximal epiphysis is the end of the bone closest to the body and the distal epiphysis is the end of the bone which is furthest away from the body

Question 4

what is the epiphysal plate

Answer 4

this separates the diaphysis and the epiphysis
it is a layer of cartilage which is where the diaphysis lengthens during bone growth

thisn is also where bone growth in childrern begins

Question 5

what is the endosteum/medullary cavity

Answer 5

the central cavity of a long bone which is com posed of blood cells and tissue

Question 6

what is the periosteum

Answer 6

a sheath of connective tissue covering the bone surface

it contains osteoblasts to help the bone grow in diameter and not length

Question 7

what is articular cartilage

Answer 7

it covers the epiphysis and is made of cartilager which reduces friction and absorbs shock
