The primary purpose of neurons is to fire , to receive input from one. All neurons have a cell body (known as the soma)- the part of a neuron. Psychologists are most interested in neurons, one of the major types (cid:1) Dendrites- small branches radiating from the cell body that receive (cid:1) messages from other cells and transmit those messages toward the rest of the cell (cid:1) from the cell body to the end of the neuron. Although neurons are essential for our ability to sense, move, and. A critical functions served by certain glial cells is to insulate the axon. These glial cells form a white substance called myelin- a fatty sheath. Sensory neutrons receive information from the bodily senses and bring. Motor neutrons carry messages away from the brain and spinal cord. Axon- transports information in the form of electrochemical reactions. Glial cells- are specialized cells of the nervous system that are.
