Study Notes
Central Nervous System
- Composed of two main parts: central nervous system (CNS) and peripheral nervous system (PNS).
Peripheral Nervous System
- Divided into two branches: autonomic nervous system (ANS) and somatic nervous system (SNS).
Autonomic Nervous System
- Controls involuntary functions such as heart rate and digestion.
- Manages organs including the heart and intestines.
Somatic Nervous System
- Responsible for voluntary movements and muscle contractions.
- Neurons in this system enable actions like writing by contracting muscle fibers.
Sensory Signals
- Neurons in the peripheral nervous system carry sensory information, such as tickling sensations, to the brain for processing.
