Study Notes
Somatic Nervous System
- Controls voluntary movements
- Composed of motor neurons that connect the central nervous system to skeletal muscles
- Enables conscious actions like walking, talking, and writing
Autonomic Nervous System
- Controls involuntary functions
- Regulates internal organs and glands
- Divided into two branches: sympathetic and parasympathetic
Autonomic Nervous System Components
- Sympathetic nervous system
- Parasympathetic nervous system
Sympathetic Nervous System Roles
- "Fight or flight" response
- Prepares the body for stressful situations
- Increases heart rate, blood pressure, and breathing rate
- Dilates pupils and airways
- Inhibits digestion
Parasympathetic Nervous System Functions
- "Rest and digest" response
- Calms the body down after stressful situations
- Decreases heart rate, blood pressure, and breathing rate
- Constricts pupils and airways
- Stimulates digestion
Neurotransmitters in the Nervous System
- Chemical messengers that transmit signals between neurons
- Play crucial roles in the functions of both somatic and autonomic nervous systems
- Examples include acetylcholine, norepinephrine, and dopamine
