What term refers to the nerve cell body including all of its processes and coverings?

The term that refers to the nerve cell body, including all of its processes and coverings, is the neuron. A neuron is the basic structural and functional unit of the nervous system. It consists of a cell body, also known as the soma, which contains the nucleus and other essential organelles. From the cell body extend several processes called dendrites, which receive signals from other neurons, and an axon, which transmits signals to other neurons. The neuron, along with all its processes and coverings, forms a complex communication network that allows for the processing, transmission, and integration of information within the nervous system.
