Question

Perichondrium is
A. Adipose tissue
B. White fibrous connective tissue
C. Yellow elastic tissue
D. Adipose connective tissue

Answer 1

Hint: The main function of this tissue to support and protect the surrounding structure. This tissue is silvery white in colour.

Complete Answer:
- Perichondrium is a sheet of thick, irregular connective tissue that covers the bone cartilage. It consists of two different membranes, the outer fibrous layer and the inner chondrogenic layer. The fibrous layer includes fibroblasts that develop collagen fibres.
- Connective tissue is a tissue that maintains, defends and gives shape to other tissues and organs in the body. Connective tissue also retains fat, helps to transfer nutrients and other substances between tissues and organs, and helps to restore weakened tissue.
- Connective tissue consists of cells, fibres and a gel-like material. Forms of connective tissue include bone, cartilage, fat, blood, and lymph tissue. Adipose tissue, or fat, is an anatomical term for loose connective tissue made up of adipocytes. Its key function is to store energy in the form of fat, though it also cushions and insulates the body.
- Perichondrium is a white fibrous connective tissue. White fibrous tissue is thick, normal connective tissue that has a silvery white appearance. This tissue is physically durable yet foldable. It consists of fibroblasts interspersed between several collagen fibres, which are very oriented in the same direction, creating a mechanically solid structure.

Thus, the correct answer is option B i.e., White fibrous connective tissue.

Note: Perichondrium acts in the growth and regeneration of cartilage. It resists external expansion when the cartilage is under pressure. The fibrous quality of perichondrium tissue makes it possible for blood to flow through your body. This constant flow of blood helps to deliver the nutrients required to reinforce and nourish the cartilage.
