Figure 35.3 Which of the following statements is
false?
- The soma is the cell body of a nerve cell.
Introduction:
Nerve cells or neurons are the cells of nervous tissue which are specialized to receive the signals of the body and transfer that signals to the other parts of the body. A neuron is composed of soma cells (cell bodies), dendrites and axons.
Answer to Problem 1VCQ
Correct answer:
The correct answer is option (c) axons carry signals from the soma to the target.
Explanation of Solution
Explanation for the correct answer:
Axons are the long tubular structure of the neuron cells. These help to conduct electrical impulses and then the information is received by another neuron and transferred to glands. Axons do not carry signals from soma cells to the target. Thus, option (c) is the correct answer.
Explanation for the incorrect answer:
Option (a) is given: The soma is the cell body of a nerve cell. Soma cell forms the cell body of neurons. It contains nucleus many organelles such as mitochondria. It functions like other cells. This is a true statement. Hence, it is an incorrect answer.
Option (b) is given Myelin sheath provides an insulating layer to the dendrites. The myelin sheath fatty substance that surrounds the axon of the nerve cell and acts as an insulating layer. This is a true statement. Hence, it is an incorrect answer.
Option (d) is given: Dendrites carry the signal to the soma. The dendrites arise from soma cell and receive signals from other cells and transmit to the soma cells. Hence, it is an incorrect answer.
Axons do not carry signals from the soma cells to the target. It only helps in conducting electric impulses which is far away from the soma cells.
