Typically has dendrites, a cell body, and a long axon that forms synapses with other neurons: made up of: Cell body (soma)- the part of a neuron that contains the nucleus; where incoming signals are integrated. Dendrites- a short extension from a neuron"s cell body that receives signals from other neurons. In vertebrates the cns consists of the brain and the spinal cord: sensory neurons - a nerve cell that carries sensory signals to the central nervous system. Occurs in cells, such as neurons and muscle cells, that have an excitable membrane: three phases:
