Question

The outer covering of cartilage is called?
A) Peritoneum
B) Periosteum
C) Endosteum
D) Perichondrium

Answer 1

Hint: Our skeleton system is composed of several different bones that help in providing strength and structure to the body. Its bones are involved in the protection and movement of the body parts.

Complete answer:
To solve this question, we have to know about cartilage. Cartilage is the smooth tissue that has elasticity or we can say a rubber like padding that is found at the end of every long bone to protect the bone in joining with the nerves. It is found in the nose, ears, rib cage, bronchial tubes, and intervertebral discs. Cartilage has the ability to withstand the compression forces and it can bend, it is formed from chondroblasts cell, Chondrocytes cell, extracellular matrix, and a mixture of collagen fibers. There are three types of cartilage; hyaline that has a glassy appearance, fibrocartilage that are intervertebral disc along with bundle of collagen fibres arranged parallel, and the elastic cartilage that are found in the epiglottis and external ear, it consists of elastic fibres and collagen fibres as well.
Now, the surface of the cartilage is covered by a dense irregular layer of connective tissue that is named as perichondrium in which peri means around. The outer layer of this cell consists of fibroblast produced by collagen and the inner layer consists of chondroblasts.

Thus, the correct option is ‘D’. Perichondrium.

Note: The peritoneum is the outer covering of the pelvic and the abdominal cavity, it consists of a mesothelium layer that gets support from the thin layer of connective tissue. Periosteum is a vascular connective tissue layer that covers the bones except the joint surface.
