Question

The human skeleton is mainly composed of
A. Bones
B. Cartilage
C. Ligaments
D. All the above

Answer 1

Hint: The human skeleton serves as the body's internal structure. It is made up of about \[270\] bones at birth, but by adulthood, this number has dropped to around \[206\] bones as some bones have fused together. About the age of \[21\], the skeleton's bone mass reaches its highest density.

Complete answer:
Option A: Bones are made up of connective tissue that is calcium-reinforced, as well as specialized bone cells.
So, option A is incorrect.
Option B: Cartilage is tough tissue, but it's softer and more malleable than bone.
So, option B is incorrect.
Option C: Ligaments are the connection between bones to bones.
Hence, option C is incorrect.
Option D: The human skeleton is the body's internal structure. Ligaments, tendons, muscles, and cartilage sustain the human body, which is made up of both fused and individual bones. The axial skeleton, which contains the vertebral column, and the appendicular skeleton are two separate divisions of the skeleton. Help, movement, defence, blood cell formation, mineral storage, and endocrine regulation are the six main functions of the human skeleton. As a result, Bones, Cartilage, and Ligaments make up most of the human skeleton. As a result, the correct response is 'all of the above’.
So, Option D is correct.

Hence, Option D is the correct answer.

Note:
There are \[206\] bones in the adult human skeleton. The skull, spine (vertebrae), ribs, arms, and legs are among them. Bones are made up of connective tissue that is calcium-reinforced, as well as specialized bone cells. Bone marrow, which produces blood cells, is found in almost all bones. The body's cartilage is an essential structural part. It's a tough tissue, but it's softer and more malleable than bone. Cartilage is a connective tissue that can be found in various parts of the body, including the elbows, knees, and ankles. The ribs' ends.
