Nervous System - Basics
The 3 major components (anatomical structures) of the nervous system.
What is the brain, spinal cord, and nerves.
Center of the neuron, contains the nucleus.
What is the cell body?
The largest and most superior part of the brain.
What is the cerebrum?
What is the frontal lobe?
A mild form of traumatic brain injury.
What is a concussion?
This part of the nervous system includes the brain and spinal cord.
What is the central nervous system?
Fibers that conduct impulses away from the cell body.
What is the axon?
The 4 lobes of the cerebrum.
What is the frontal, parietal, temporal, occipital?
Responsible for all things vision.
What is the occipital lobe?
Acute inflammation of the meninges. Most often caused by viral or bacterial infection.
What is meningitis?
This part of the nervous system includes the nerves.
What is the peripheral nervous system?
Fibers that receive & carry messages toward the cell body.
What are dendrites?
Responsible for balance & equilibrium. Coordinates skeletal muscle.
What is the cerebellum?
Responsible for auditory and olfactory perception.
What is the temporal lobe?
The two divisions of the autonomic nervous system.
What is parasympathetic and sympathetic?
What is sensory?
Insulates fibers and increases the rate of transmission of the nerve impulse.
What is myelin sheath?
Responsible for blood pressure, breathing, and heart rate.
What is the brain stem?
Responsible for processing sensory information such as touch, temperature, and taste.
What is the parietal lobe?
This part of the nervous system prepares the body to either fight or run from a threat.
What is the sympathetic nervous system?
Nerves that information FROM the CNS
What are motor neurons?
Gaps between Schwann cells, allow impulse to jump from node to node.
What are Nodes of Ranvier?
Large fiber tract that connects the two cerebral hemispheres.
What is the corpus callosum?
This structure is deep within the cerebrum, housing multiple glands.
What is the diencephalon?
The function of the autonomic nervous system.
What is maintain homeostasis and control involuntary body activities?
