Nervous System
This division of the nervous system contains all of the nerves that lie outside of the spinal cord/brain; it extends to the outside of the body
This division of the nervous system includes the brain and spinal cord
Central Nervous System
This structure connects the brain to the rest of the body through the peripheral nervous system; it relays sensations from the periphery of the body to the brain AND carries brain’s commands to peripheral nerves
Spinal cord
The cerebellum, the medulla, and the pons make up this brain region
The hindbrain
These sections on the motor homunculus homunculus are the largest, proportional to how much cortex area is dedicated them
Hands + Face
Branch of the nervous system that regulates involuntary and unconscious actions; comprised of nerves that connect to the heart, blood vessels, smooth muscles, and glands
Autonomic Nervous System
The two subdivisions of the Autonomic Nervous System
Sympathetic & Parasympathetic Nervous Systems
In the occipital lobe, this structure is the main cortical region of the brain that receives, integrates, and processes visual information relayed from the retinas
Primary visual cortex
The lobe whose main functions are sensory perception and integration, including the management of taste, hearing, sight, touch, and smell.
Parietal Lobe
This lobe is responsible for motor function and higher cognitive functions (such as memory, emotions, impulse control, problem solving, social interaction)
Frontal Lobe
This branch of the nervous system involves nerves that connect to skeletal muscles and to sensory receptors & allow voluntary movement
Somatic Nervous System
The two subdivisions of the Peripheral Nervous System
Somatic & Autonomic Nervous Systems
Main cortical region of the temporal lobe that is dedicated to the processing and comprehension of what you are hearing
Primary auditory cortex
The visual processing lobe. Main functions are visuospatial processing, distance and depth perception, color determination
Occipital Lobe
This lobe's main functions are processing auditory information, language comprehension, and storage/retrieval of memories
Temporal Lobe
This branch of the nervous system is the emergency response system; mobilizes the body's resources for emergencies. "Fight, flight, or freeze" system
Sympathetic Nervous System
This type of nerve fiber carries information inward to the central nervous system from the periphery of the body
Afferent (or sensory) nerve fibers
The cortical region of the frontal lobe that plays a crucial role in the execution and control of voluntary movements
The primary motor cortex
The structure which all sensory info except smell must pass through to get to the cerebral cortex. Also regulates alertness
Thalamus
Responsible for emotional processing + regulation, and the activation of the "fight, flight, freeze" response
Amygdala
Branch of the nervous system that functions to calm an individual and conserve bodily resources; "Rest & Digest"
Parasympathetic Nervous System
Axons that carry information outward from the Central Nervous System to the periphery
Efferent (motor) nerve fibers
The cortical area of the parietal lobe which receives sensory information from the skin and body parts
Primary somatosensory cortex
Structure involved in memory processes like the consolidation of memories and learning
Hippocampus
Hypothalamus
