Hint: The nerve cell neurons have to perform a very important function of transferring instructions generated by the brain in the form of nerve impulses, according to which different functions of our body take place.
Complete answer:
-Nerve cells receive messages from different parts of the body and transfer the messages to the brain. The brain sends commands for the functioning of different organs of the body via nerves.
-Whenever a sensory receptor receives information from the environment, the end of the dendrite tip sets of a chemical reaction to create an electrical impulse. This impulse travels from the dendrite to the cyton and then through the axon reaches the axon ends.
-As the message gets transferred from one neuron to another, it finally reaches the muscle cells or glands (effector organ) based on which the impulses will be converted into action.
-Neuron comprises a cyton or cell body which consists of a nucleus, mitochondria, Golgi body, and endoplasmic reticulum. The axon is an extension of the dendrites and it consists of axolemma, myelin sheath, and neurilemma. The small branching of the cyton is the dendrites.
So, the correct answer is “all of the above”
Note: -The mitochondria in the muscle cells are comparatively larger in number to produce energy for muscular action.
-At the end of the axon, the electrical impulse releases some chemicals, these chemicals cross a gap or synapse by creating a potential difference through the accumulation of ions.
-The human body contains about 100 billion neurons in the brain and 13.5 million neurons in the spinal cord.
-Depending upon the location and functions to be performed neurons have different shapes and sizes.
