Study Notes
Types of Neurons
- Sensory neurons carry electrical signals from receptors to the CNS.
Structure of Neurons
- Cell bodies of sensory neurons are located in dorsal root ganglia or in ganglia associated with cranial nerves.
- The axon carries impulses away from the cell body.
Cell Body
- The cell body (soma) contains the nucleus and most of the cytoplasm.
Interneurons
- Interneurons integrate and process information within the CNS.
- The main function of interneurons is to integrate and process information within the CNS.
Axons
- Each neuron typically has only one axon.
Synapses
- Axon terminals contain vesicles with neurotransmitters at a synapse.
- Synapses play a crucial role in neural transmission as they allow neurons to communicate with each other.
Peripheral Nervous System
- Schwann cells provide myelination and support to axons in the peripheral nervous system.
Receptors and Effectors
- Receptors detect stimuli, while effectors respond to stimuli in the context of neurons.
