Hello students, in this question first we need to describe the structures of femur diaphysis and epiphyseal ends and in the next part we need to explain how these structures contribute to the normal functioning of the body.
00:17
The femur also known as thigh bone is indeed a classic example of long bone.
00:23
Long bones such as femur consists of a tubular shaft called as diaphysis and two extended ends called as epiphysis.
00:32
First diaphysis.
00:34
Diaphysis of femur is long cylindrical shaft located between two epiphysis.
00:41
It consists of a compact bone tissue which forms a sturdy and rigid structure.
00:47
The outer surface of diaphysis is covered by fibrous sheath called as periosteum which provides support and attachment for muscles, tendons and ligaments.
01:00
Within the diaphysis is the medullary cavity which is a hollow space filled with yellow bone marrow which stores adipose tissue.
01:11
The structural sense behind the diaphysis construction is primarily related to providing support and strength to the bone.
01:20
The compact bone tissue in the diaphysis allows it to withstand mechanical stresses.
01:26
The hollow medullary cavity reduces the weight of the bone while providing space for the storage of adipose tissue...
