Nervous System - Coggle Diagram
Nervous System
Central Nervous System, brain and spinal cord. Brain receives and processes sensory information, spinal cord conducts signals to and from brain, controls reflexes
Spinal Cord controls reflexes, sends information to and from the brain
-
Cerebellum coordinates movement; controls posture & balance. Receives sensory input about body position from spinal cord & motor input from brain, stores as muscle memory
Peripheral Nervous System, anything that comes out of the brain and spinal cord. afferent division brings sensory info to the CNS, efferent division sends motor info from the CNS
Somatic, controls skeletal muscles, made of both sensory and motor neurons
Autonomic, regulates bodily functions NOT under conscious control, made only of motor neurons
Parasympathetic, rest or digest, increased digestion and excretion; decreased heart rate
Sympathetic, fight or flight, increased mental alertness, heart rate, blood pressure, reduced digestion
-
Spinal Nerves carries sensory, motor, and autonomic signals between spinal cord and the body
Neurons, send and receive signals, basic units of the nervous system
Sensory Neurons monitor external and internal environments, relay information to CNS neurons
-
Interneuron located only in the CNS, distributes sensory info and coordinates motor activity
-
-
-
Cerebral Cortex
Parietal Lobe
Somatosensory cortex processing sensory info such as touch, temperature, pain
-
Frontal Lobe
-
Pre-frontal cortex personality traits, thinking, reasoning
-
-
Cerebrum Largest part of the brain, the grey matter
