Nervous System
The Nervous System works to maintain homeostasis by responding to stimuli, simulating muscles and simulating glands. The nervous system consists of a mass of neurons, which are supported by neuroglial cells. Neurons have specific classification due to their structure. There are multipolar neurons, bipolar neurons, and unipolar neurons.
Multipolar Neuron
Multipolar neurons have many processes arising from the cell body. They have one axon and many dendrites, and are found within the brain and spinal cord |
Bipolar Neuron
Bipolar neurons only have 2 processes arising from each ed of the cell body. They have one axon and one dendrite and are found in the eyes, ears, and nose. |
Unipolar Neurons
Unipolar neurons have a single process arising form the cell body. The process divides into 2 branches. |
