Some cells of the central nervous system are located in the
- a. spinal cord.
- b. muscles
- c. glands.
- d. Both a and c are correct.
Introduction:
Nervous system controls and coordinates the functions of body. It communicates through the network of cells and the nerve impulses sent by the neuron cells. The nervous system in the vertebrates is divided into two main divisions, central nervous system and peripheral nervous system.
Answer to Problem 1MCQ
Correct answer:
Some cells that belong to central nervous system are located in the spinal cord. Therefore, option (a) is correct.
Explanation of Solution
Reason for the correct statement:
The central nervous system consists of spinal cord and brain. The cells of central nervous system would belong to these organs only. The main function of these organs is to combine the sensory information and coordinate the responses of the body.
Option (a) is given as “spinal cord”.
As, “some cells of the central nervous system are located in the spinal cord”, is the right answer.
Hence, option (a) is correct.
Reasons for the incorrect statements:
Option (b) is given as “muscles”.
Muscles are the part of the peripheral nervous system. Hence, it is a wrong answer.
Option (c) is given as “glands”.
Glands receive nerve impulses from the central nervous system carried by the peripheral nervous system. Hence, it is a wrong answer.
Option (d) is given as “Both a and c are correct”.
Spinal cord is the part of central nervous system whereas glands are the part of peripheral nervous system. Hence, it is a wrong answer.
Hence, options (b), (c) and (d) are incorrect.
Spinal cord is the part of the central nervous system. Thus some cells of this nervous system are located in the spinal cord.
