Study Notes
Nervous System Overview
- Composed of the brain, spinal cord, and nerves.
- Two main divisions:
- Central Nervous System (CNS): Brain and spinal cord.
- Peripheral Nervous System (PNS): Nerves connecting the CNS to the rest of the body.
Brain
- Control center of the body.
- Regulates: thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger, and other bodily processes.
- Complex organ.
Spinal Cord
- Cylindrical structure running through the spine, from brainstem to lower back.
- Major communication pathway between brain and body.
Nerves
- Bundles of fibers connecting brain and spinal cord to body parts.
- Different types:
- Sensory nerves: Carry signals from body to brain.
- Motor nerves: Carry signals from brain to muscles.
- Mixed nerves: Carry both sensory and motor signals.
Nervous System Diseases
- Alzheimer's disease: Progressive brain disorder affecting memory, thinking, and basic tasks.
- Parkinson's disease: Movement disorder worsening over time, affecting nervous system control of movement.
- Multiple Sclerosis (MS): Immune system attacks brain and spinal cord, causing diverse symptoms like vision problems, movement difficulties, and cognitive changes.
- Epilepsy: Characterized by recurrent seizures, abnormal electrical activity in neurons.
- Amyotrophic Lateral Sclerosis (ALS): Progressive disorder damaging nerve cells in brain and spinal cord (Lou Gehrig's disease).
