Study Notes
Sensory Neuron Characteristics
- Cell bodies of sensory neurons are located outside the spinal cord in clusters called Dorsal Root Ganglia (DRG).
- Sensory neurons have a single axon with two branches.
- One branch of the axon extends to sensory endings in the skin.
- The other branch of the axon enters the Central Nervous System (CNS) and synapses with neurons in the dorsal horn of the spinal cord.
- Sensory neurons have different receptors that allow them to sense various stimuli, including:
- Touch
- Pressure
- Vibration
- Limb position
- Heat
- Cold
- Pain
