Study Notes
Nervous System
- Central Nervous System (CNS): Composed of the brain and spinal cord. It acts as the body's control center, coordinating bodily activities and receiving and transmitting impulses.
- Peripheral Nervous System (PNS): A network of nerves carrying messages to and from the CNS; enabling rapid bodily responses.
- Brain:
- Cerebrum: Divided into two hemispheres; controlling memory, intelligence, muscle control.
- Cerebellum: Controls balance, posture, and coordination.
- Brainstem: Regulates involuntary functions like breathing and heartbeat.
- Spinal Cord: Crucial for communication between the brain and the rest of the body.
- Nerves: Carry sensory information and motor commands.
- Right Hemisphere Control: Controls the left side of the body.
- Peripheral Nerves: Carry messages to and from the central nervous system.
- Lobes of the Cerebrum:
- Frontal Lobe: Involved in decision-making, problem-solving, and planning.
- Temporal Lobe: Processes sensory information, including hearing, memory, and language.
- Parietal Lobe: Handles sensory information processing, including touch.
- Occipital Lobe: Responsible for processing visual information.
