Final answer:
A network of neurons that perform a common function is a neuronal pool, while a bundle of axons in the peripheral nervous system is called a nerve. The soma is the part of the neuron with the nucleus, and the axon transmits electrical signals to target cells.
Step-by-step explanation:
A network of neurons that perform a common function is referred to as a neuronal pool. In the peripheral nervous system, a bundle of axons is known as a nerve. Neurons are specialized cells capable of transmitting chemical or electrical signals, while the glia provide support and are essential for the maintenance and functionality of neurons.
The part of the neuron containing the nucleus is the soma or cell body, and the part that transmits the electrical signal to a target cell is the axon. A neuron's main function is to conduct nerve impulses which are facilitated by structures such as the myelin sheath and neurotransmitters.
