There are three main types of neurons in the nervous system:
1. Sensory neurons: These neurons are responsible for transmitting sensory information from the body to the central nervous system. They are specialized to detect stimuli such as light, sound, touch, taste, and smell, and convert these stimuli into electrical signals that can be transmitted to the brain.
2. Motor neurons: These neurons are responsible for transmitting signals from the central nervous system to muscles and glands, allowing for movement and bodily functions. Motor neurons receive signals from other neurons and transmit them to muscles to initiate movement or to glands to release hormones.
3. Interneurons: These neurons act as a bridge between sensory and motor neurons, relaying signals between them. Interneurons are found in the central nervous system and are involved in processing and integrating information from sensory neurons before transmitting signals to motor neurons. They play a crucial role in coordinating complex movements and behaviors.

Sensory Neurons (Afferent Neurons)
- Receive sensory information from the environment or within the body
- Transmit signals towards the central nervous system (CNS)
Motor Neurons (Efferent Neurons)
- Transmit signals from the CNS to muscles, glands, or other organs
- Control movement, secretion, and other effector functions
Interneurons (Central Neurons)
- Found within the CNS
- Connect sensory and motor neurons, forming complex neural circuits
- Process and integrate signals
Based on their morphology and function, neurons can be further classified into various subtypes:
Unipolar Neurons:
- Have a single process that extends from the cell body
- Common in sensory neurons that receive stimuli from the periphery
Bipolar Neurons:
- Have two processes extending from the cell body
- Found in specialized structures such as the retina and olfactory epithelium
Pseudounipolar Neurons:
- Have a single axon that divides into central and peripheral branches
- Most common type of sensory neuron in the peripheral nervous system
Multipolar Neurons:
- Have multiple dendrites and a single axon
- Common in interneurons and motor neurons in the CNS and PNS
Specific Types of Neurons with Distinct Functions:
- Pyramidal Neurons: Primary neurons in the cerebral cortex involved in higher cognitive functions
- Purkinje Cells: Neurons in the cerebellum responsible for motor coordination
- Dopaminergic Neurons: Neurons that release dopamine, a neurotransmitter involved in reward, motivation, and movement
- Serotonergic Neurons: Neurons that release serotonin, a neurotransmitter involved in mood regulation, sleep, and appetite
- GABAergic Neurons: Neurons that release GABA, an inhibitory neurotransmitter involved in controlling neural activity
- Receive sensory information from the environment or within the body
- Transmit signals towards the central nervous system (CNS)
