Study Notes
Structural Classification of Neurons
- Refers to the physical appearance of a neuron.
- Three main types: multipolar, bipolar, and unipolar.
Multipolar Neurons
- Characterized by multiple processes extending from the cell body.
- Most common type of neuron in the nervous system.
Bipolar Neurons
- Composed of one axon and one dendrite.
- Primarily found in special sensory organs, such as the retina of the eye.
Unipolar Neurons
- Have a single process that branches out from the cell body.
- Commonly found in sensory neurons that transmit information to the CNS.
Functional Classification of Neurons
- Focuses on the role of the neuron in the nervous system.
- Main classifications include sensory, motor, and interneurons.
Sensory Neurons
- Also known as afferent neurons.
- Responsible for transmitting sensory information toward the central nervous system.
Motor Neurons
- Referred to as efferent neurons.
- Carry signals away from the central nervous system to execute actions based on sensory input.
Interneurons
- Located between sensory and motor divisions.
- Found exclusively in the central nervous system and make up about 99% of all neurons.
