In this video Paul Andersen explains the basic anatomy of a neuron; including the dendrites, cell body, axon hillock, axon, and axon terminal. He also descr Upper and lower motor neurons control the voluntary movements. Upper motor neurons are located mainly in the primary motor and premotor areas of cerebrum. Lower motor neurons are located in the motor nuclei of the cranial nerves in the brainstem and anterior horn of spinal cord.

The latter localize both in the brainstem and the spinal cord and are the mediators Neurons can generally be anatomically characterized as unipolar, bipolar, or multipolar. A number of anatomically distinct neuron types, such as sensory, motor, and interneurons, have evolved to participate in different organismal functions.

•Sensory neurons pick up and transmit information from sensors that detect external stimuli (light, heat, touch) and internal conditions (blood pressure, muscle tension). •Interneurons, in the CNS, integrate the sensory input •Motor output leaves the CNS via motor neurons, which communicate with effector cells (muscle or endocrine cells).
