Study Notes
Neurons
- Individual nerve cells that receive, process, and relay information
- Found throughout the nervous system
- Three types of neurons:
Sensory (afferent) neurons
- Located in the peripheral nervous system (PNS)
- Transmit sensory information to the central nervous system (CNS)
Interneurons
- Located in the central nervous system (CNS)
- Communicate between sensory and motor neurons
- Receive information from both sensory and motor neurons
Motor (efferent) neurons
- Located in the central nervous system (CNS)
- Transmit motor messages away from the CNS to muscles and glands
Neurons
- Neurons are nerve cells responsible for receiving, processing, and transmitting information throughout the body.
- There are three types of neurons: sensory, interneurons, and motor neurons.
- Sensory neurons (afferent) transmit sensory information from the peripheral nervous system (PNS) to the central nervous system (CNS).
- Interneurons are located within the CNS and act as intermediaries, communicating signals between sensory and motor neurons.
- Motor neurons (efferent) transmit motor signals from the CNS to muscles and glands, initiating movement and glandular activity.
- The flow of information within the nervous system follows this pattern: sensory neurons bring information to the CNS, interneurons process and relay information within the CNS, and motor neurons convey information from the CNS to effectors (muscles or glands).
