Question

Cells present in nervous tissue that protect neurons are

• A. Axons
• B. Neuroglial cells
• C. Osteocytes
• D. Chondrocytes

Answer 1

The correct option is B

Neuroglial cells

The correct option is B.
Explanation of the correct option:

1. Neurons are the basic unit of nervous tissue and are made up of three major parts: cell body, dendrites and axons.
2. Neurons are protected by a type of cell called neuroglial cell.
3. The neuroglial cells produce a covering called myelin sheath around nerve fibres which increases the speed of the nerve impulse conduction.

Explanation of the incorrect option:
Option A:
The longest part of neurons that arises from cell body is called axon and it carries impulses away from the cell body of the neuron.
Option C:
The cells constituting the bone are called osteocytes.:
Option D:
The cells constituting the cartilage are called chondrocytes.

Final answer:
Cells present in nervous tissue that protect neurons are neuroglial cells.
