Study Notes
Nervous System Overview
- The nervous system is a complex communication network in the body, allowing for rapid responses and coordination of activities.
- It comprises all nerve cells within both the peripheral and central systems.
Peripheral Nervous System (PNS)
- The PNS consists of sensory and motor neurons, linking the central nervous system to the body's extremities and organs.
- It facilitates communication between the brain/spinal cord and the rest of the body.
Central Nervous System (CNS)
- The CNS is made up solely of the brain and spinal cord, serving as the main processing center for information and decision-making.
Autonomic Nervous System (ANS)
- Part of the PNS, the ANS regulates involuntary functions such as digestion and heart rate, influencing internal organ activities.
Somatic Nervous System
- The somatic nervous system is a division of the PNS responsible for voluntary muscle movements, overseeing the body's skeletal muscles.
- Referred to as the skeletal nervous system, it enables conscious control of movement.
Sympathetic Nervous System
- This division of the ANS prepares the body for high-energy activities, triggering the fight-or-flight response.
- It mobilizes energy reserves to face perceived threats or stressors.
Parasympathetic Nervous System
- Opposite to the sympathetic system, the parasympathetic division promotes relaxation and restorative processes within the body.
- It conserves energy by slowing heart rate, enhancing digestion, and supporting other functions essential for recovery.
