Study Notes
Neuron Classification
-
Neurons are classified based on the number of processes extending from the cell body.
-
Multipolar neurons have one axon and two or more dendrites. Most neurons are multipolar.
-
Bipolar neurons have one dendrite and one axon. Bipolar neurons are found in the retina, olfactory mucosa, and the cochlear and vestibular ganglia, serving the senses of sight, smell, and balance, respectively.
Neuron Function
-
Sensory neurons are afferent and receive stimuli from receptors throughout the body.
-
Motor neurons are efferent, sending impulses to effector organs such as muscle or glands.
-
Interneurons establish relationships among other neurons, forming complex functional networks or circuits in the CNS and retina.
Synapses
-
Axosomatic synapses form between an axon and a cell body.
-
Axodendritic synapses form between an axon and a dendrite.
-
Axoaxonic synapses occur when an axon forms a synapse with another axon. These synapses modulate the activity of the other two types.
