Detailed explanation-1: -Also known as a soma, the cell body is the core section of the neuron. The cell body contains genetic information, maintains the neuron’s structure, and provides energy to drive activities. Like other cell bodies, a neuron’s soma contains a nucleus and specialized organelles.
Detailed explanation-2: -Astrocytes provide nutrients to neurons, maintain their extracellular environment, and provide structural support. Microglia scavenge pathogens and dead cells. Ependymal cells produce cerebrospinal fluid that cushions the neurons.
Detailed explanation-3: -They are the structural and functional elements that help in the coordination of the body activities. They are specialized to perform conduction and respond to stimuli. They function by transmitting nerve impulses among themselves. They have three distinct parts, including a cell body, axon, and dendrites.
Detailed explanation-4: -The region of the neuron containing the nucleus is known as the cell body, soma, or perikaryon (Figure 8.2).
