Study Notes
Nervous System Overview
- The nervous system is essential for processing information and responding to stimuli.
- Divided into two primary divisions: Central Nervous System (CNS) and Peripheral Nervous System (PNS).
Central Nervous System (CNS)
- Comprised of the brain and spinal cord.
- Receives sensory information through afferent nerves.
- Initiates responses and actions via efferent nerves.
Peripheral Nervous System (PNS)
- Functions as a communication network between the CNS and the rest of the body.
- Divided into two main divisions: Somatic and Autonomic.
Somatic Nervous System
- Responsible for voluntary control of skeletal muscles.
- Allows for conscious movement and coordination.
Autonomic Nervous System (ANS)
- Regulates involuntary functions such as heartbeat and digestion.
- Divided into two subdivisions:
- Sympathetic Division: Prepares the body for "fight or flight" responses, increasing heart rate and energy mobilization.
- Parasympathetic Division: Promotes "rest and digest" functions, conserving energy and enhancing digestion.
