Study Notes
Bipolar Neurons
- Structure: Two processes; one axon and one dendrite
- Function: Specialized for sensory processing
Functional Classification
-
Sensory Neurons (Afferent Neurons):
- Function: Transmit sensory information from receptors to the central nervous system (CNS)
- Location: Cell bodies in sensory ganglia (e.g., dorsal root ganglia); axons extend to the CNS
-
Motor Neurons (Efferent Neurons):
- Function: Transmit signals from the CNS to muscles and glands
- Location: Cell bodies in the CNS (e.g., anterior horn of the spinal cord for somatic motor neurons); axons extend to effector organs (e.g., skeletal muscle)
-
Interneurons (Association Neurons):
- Function: Integrate sensory and motor information within the CNS
- Location: Found entirely within the CNS, such as the spinal cord and brain (e.g., in the cerebral cortex)
