Question

Which of the following is not a part of nervous tissue?

• A. Cyton
• B. Axon
• C. Myelinated
• D. Nephron

Answer 1

The correct option is D

Nephron

The correct option is D.

Explanation of the correct option :

1. Nerve tissue is made up of nerve cells, which are highly specialized unit cells.
2. Neurons play an important role in the transmission of nerve impulses from one cell to another.
3. The main function of these cells is to receive impulses from perceptions.
4. These cells are generally found in the brain and spinal cord.
5. The three parts of a neuron are as follows:
   • Cyton, or cell body, has a central nucleus and cytoplasm containing Nissl's granules, which are strongly pigmented particles.
   • Dendrons, also known as dendrites, are small processes that emerge from the Cyton and branch out into dendrites.
     The axon, also known as a nerve fiber, is a long cylindrical structure with a uniform diameter. It produces delicate branches at the end of its stem.
   • Synaptic knobs are bulb-like structures on these branches.
6. The structure that produces urine in the process of eliminating waste and excess chemicals from the blood is known as a nephron.

Final answer: Nephron is not a part of nervous tissue.
