The cell body of a neuron contains the
a. nucleus.
b. dendrites.
c. axon.
d. neuroglia.
Introduction:
Nerve cells also known as neurons make up the nervous system along with neuroglia. Together these cells help to control the body functions, process emotions and decode information. Neurons conduct the signals and neuroglia has supporting cells which protect and support the nervous system. A neuron is made of cell body, axon and dendrites.
Answer to Problem 1PL
Correct answer:
The correct answer is option (a) nucleus.
Explanation of Solution
Explanation/justification for the correct answer:
Option (a) nucleus. A neuron consists of a cell body or soma which has all the important organelles required for its functioning. Some of these organelles are the nucleus, mitochondria and endoplasmic reticulum. The nucleus contains DNA and is responsible for regulating all the processes within the neuron. So, the correct answer is option (a).
Explanation for incorrect answer:
Option (b) dendrites. Dendrites are part of the neuron and receive signals or information from another neuron. They are connected to the cell body but are not a part of it. So, this is an incorrect option.
Option (c) axon. Axon is part of the neuron and transmits signals to other neurons. It is also connected to the cell body but is not a part of it. So, this is an incorrect option.
Option (d) neuroglia. Neuroglia consists of cells of the nervous system which are not neurons. These cells protect and support the nervous system by forming the myelin sheath, destroying pathogens, etc. So, this is an incorrect option.
