Study Notes
Nervous System Overview
- The nervous system acts as the body's control center, regulating both voluntary and involuntary actions.
- It enables the organism to adapt to its surroundings through its inherent properties: sensitivity, conductivity, and responsiveness.
- Neural pathways, formed by nerve cell extensions, act like electrical wires, allowing impulses to travel.
- Sensory impulses travel from peripheral sources (skin, membranes, muscles, etc.) to the central nervous system (CNS) via afferent nerves.
- Motor impulses travel from the CNS to muscles and glands via efferent nerves.
- The CNS receives continuous sensory input from the environment, enabling it to adjust bodily functions and send motor commands to muscles, blood vessels, and internal organs.
- The nervous system plays a critical role in survival.
Parts of the Nervous System
- The nervous system is divided into the central nervous system (CNS) and the peripheral nervous system (PNS).
