Question

3. Describe the structure and functions of following
tissues :
(a) Epithelial tissue
(b) Muscular tissue
(c) Nervous tissue
(d) Connective tissue​

Answer 1

Answer:

Epithelial tissue:

• It is the covering or protective tissues in the animal body.
• It forms a barrier to keep different body systems separate.

• The skin, the lining of the mouth, the lining of blood vessels, lung alveoli, and kidney tubules are made up of this type of tissue.

Muscular tissue:  

• It is a soft tissue that composes muscles in animal bodies and gives rise to muscles' ability to contract.

Nervous tissue:

• It is the main component of the two parts of the nervous system; the brain and spinal cord of the central nervous system (CNS), and the branching peripheral nerves of the peripheral nervous system (PNS), which regulates and controls bodily functions and activity.

Connective tissue:

• Tissue that connects, supports, binds or separates other tissues or organs, typically having relatively few cells embedded in an amorphous matrix, often with collagen or other fibers and including cartilaginous, fatty and elastic tissues.
