Study Notes
The Nervous System
- The nervous system is the body's communication network, controlling and coordinating all activities.
- It transmits signals between different parts of the body and the brain.
- It enables functions like sensation, movement, thought, and emotion.
Central Nervous System (CNS)
- The CNS processes sensory information, controls motor functions, and regulates vital functions like breathing and heartbeat.
- The brain is the control center for processing information.
- The spinal cord transmits signals between the brain and the body.
Peripheral Nervous System (PNS)
- The PNS connects the brain and spinal cord to the rest of the body for communication and coordination.
- It transmits sensory information from the body to the CNS.
- It sends motor commands from the CNS to muscles and glands.
- It regulates involuntary functions like heartbeat and digestion via the autonomic nervous system.
Autonomic Nervous System
- Regulates involuntary functions like heartbeat and digestion.
- The sympathetic nervous system activates the "fight-or-flight" response.
- The parasympathetic nervous system promotes relaxation and recovery.
Brain Regions
- The cerebrum is the largest part of the brain and is involved in higher functions like thinking, memory, and decision-making,
- The cerebellum is involved in motor coordination, balance, and cognitive functions.
- The brain stem connects the brain to the spinal cord and regulates basic physiological functions.
- The frontal lobe is responsible for decision-making, problem-solving, conscious thought, attention, emotional and behavioral control, speech production, personality, and intellect.
- The occipital lobe is responsible for visual processing and interpretation, visual data collection regarding color, motion and orientation, object and facial recognition, depth and distance perception, and visual world mapping.
- The parietal lobe is responsible for sensory information processing (touch, pressure, pain, position, vibration, temperature). It also processes spatial processing and spatial manipulation (navigating).
- The temporal lobe is responsible for language, speech formation, learning, memory, comprehension, hearing, and sound-to-visual image conversion.
Neurotransmitters
- Dopamine: Involved in reward, motivation, and movement.
- Serotonin: Regulates mood, appetite, and sleep.
- Acetylcholine: Involved in muscle movement and memory.
- GABA: Inhibitory neurotransmitter, helping calm the brain.
- Glutamate: Excitatory neurotransmitter, involved in learning and memory.
- Endorphins: The body's natural painkillers and mood enhancers, released during exercise or stress.
- Melatonin: Regulates the sleep-wake cycle.
