Hint: Cells within the nervous system , called neurons, interact in unusual ways with each other.

Complete Answer:
- The majority of neurons have a body of cells, an axon , and dendrites. The cell body comprises the cytoplasm and the nucleus. The axon spreads from the body of the cell and, before terminating at nerve terminals, sometimes gives rise to several smaller branches.
- Dendrites stretch from the body of the neuron cell and get signals from other neurons. The contact points where one neuron interacts with another are synapses. With synapses produced by the ends of axons from other neurons, the dendrites are shielded.
- Because of the structural and functional properties of interconnected neurons, the brain is what it is. The mammalian brain comprises between 100 million and 100 billion neurons, depending on the species. A cell body, dendrites, and an axon form each mammalian neuron.
- By having data that came from the stimulus, neurons play a receptive role. This receptive role of the neurons ensures that information is efficiently transmitted and, therefore, the appropriate response to stimuli is ensured.
- In the dendrites (receptive components) as well as the cell body of the neuron, integrative function occurs.it requires the summing up of excitatory and inhibitory responses (this is synthesis of incoming signals) in order to decide if such information should be transmitted.
Transmission is either electrical or chemical, from one neuron to another.
- In electrical transmission, by passive electrical means, a neuron is affected by another. It is the potential shift in one of the neurons in chemical transmission that results in the release of a chemical neurotransmitter that diffuses another neuron in turn.
Schwann cells are responsible for the formation of myelin sheath.

The correct answer is option(C) Forms the myelin sheath.

Note: The neuron is the brain 's fundamental working organ, a specialised cell designed to pass on information to other cells of the nerve , muscle, or gland.
