Question

In the matrix, lies the bone cells called-
A.Chondroclast
B.Osteoclast
C.Osteoblast
D.Osteocyte

Answer 1

Hint:Bones are considered to be the stronger part of the human body. The smallest bone in the human body is the stapes in-ear while the longest bone is the femur in the thigh region.

Complete answer:Bones are considered to form the major framework of the body and provide shape and size to the body. Along with forming the framework of the body, it contributes to red blood cell formation, providing protection to the various organs.
Let’s see the options-
Option A- chondroclast- are described to be cells in the bone which help in absorption or dissolution of cartilages. They are also called perichondrial cells.
Option B- osteoclast- leads to absorption or dissolution of the bone.
Option C- osteoblast- helps in the mineralization of bones and repairing of bones while the formation of bones.
Option D- osteocyte- a cell that lies within the fully formed bone. This is generally derived from osteoblast or bone-forming cells.
It is the bone cell that is found in the matrix. The bone matrix has three types of bone cells which are generally known as bone-forming cells, bone mineralizing cells, and bone dissolution or absorbing cells.
So, option D, Osteocyte is the correct answer.

Note:Bones have collagen protein which provides softness to them and calcium phosphate present provides stiffness to the framework which together provides strength to the bone and helps them to resist stress. Mineralization of bone leads to attain strength and gain stability.
Types of skeleton differentiated in the human body-
Appendicular skeleton- consists of 80 bones which include the skull, hyoid bone, ear ossicles, sternum, ribs, vertebrae.
Axial skeleton- consists of 126 bones which include pectoral girdle, pelvic girdle, forelimbs, hind limbs.
