Study Notes
Nervous System Overview
- The central nervous system (CNS) is responsible for coordinating actions and sensory information.
Peripheral Nervous System (PNS)
- The main function of the PNS is to connect the CNS to the rest of the body, transmitting and receiving information.
- The PNS has two main parts: the somatic nervous system (SNS) and the autonomic nervous system (ANS).
Composition of Nerves in PNS
- Nerves in the PNS are mainly composed of axons, which are long, slender extensions of neurons.
Function of Sensory Nerves
- Sensory nerves in the nervous system are responsible for transmitting information from sensory receptors to the CNS, allowing us to perceive and respond to the world around us.
