Study Notes
Purpose of the Nervous System
- Coordinates all body activities.
- Enables response and adaptation to internal and external changes.
Types of Nervous System
- Comprises Central Nervous System (CNS) and Peripheral Nervous System (PNS).
Central Nervous System (CNS)
- Major structures include the Brain and Spinal Cord.
Brain Lobes and Functions
- Frontal Lobe: Responsible for reasoning and thought processes.
- Parietal Lobe: Integrates sensory information from the body.
- Temporal Lobe: Processes auditory information received from the ears.
- Occipital Lobe: Handles visual information from the eyes.
Spinal Cord
- Acts as a link between the brain and peripheral nerves.
- Sensory neurons relay impulses to the spinal cord, which then forwards signals to the brain.
Afferent vs Efferent
- Afferent Neurons: Carry sensory signals to the CNS.
- Efferent Neurons: Transmit motor commands from the CNS to the body.
Peripheral Nervous System (PNS)
- Comprises all nerves branching from the brain and spinal cord.
- Divided into two main divisions: Somatic and Autonomic.
Somatic Peripheral Nervous System
- Connects to skin, sensory organs, and skeletal muscles.
- Manages all voluntary muscle movements and processes external stimuli.
Autonomic Peripheral Nervous System
- Oversees involuntary bodily functions.
- Further divided into:
- Sympathetic Division: Activates the "fight or flight" response.
- Parasympathetic Division: Promotes "rest and digest" functions.
