Parts of the brain
Largest part of the brain which controls voluntary complex behavior such as reading, movement and speech.
What is the cerebrum
Receives impulses from other neurons or sense organ
What are dendrites
Receives sensory information and initiates motor control. Composed of the brain and spinal cord.
What is the central nervous system
Affects the sensation of pleasure, such as eating.
What is dopamine
Controls voluntary and some involuntary movement such as muscle coordination and balance
What is the cerebellum
Takes impulses away from the cell body and brings them to the muscles, glands or another neuron.
What is the axon
Nerves leading to and from sensory structures and muscles. Controls voluntary actions.
What is the somatic nervous system
Regulates temperature, sensory perception and mood control
What is serotonin
Controls involuntary activities such as breathing, heartbeat, blood flow, coughing, vomiting, swallowing, hiccupping, digestion, etc.
What is the Medulla Oblongata
Contains the nucleus and other organelles and controls metabolic activities of the neuron
What is the cell body
Controls involuntary actions
What is the autonomic nervous system
Acts as natural painkillers as well as regulates some emotions
What are endorphins
Relays information to the appropriate part of the cerebrum.
What is the Thalamus
Cells that compose the external covering on the axon
What are Schwann cells
Helps the body respond to danger (fight or flight). Increases heart rate, breathing rate, etc.
What is the sympathetic nervous system
Readies the body to respond to danger or other stressful situations
What is norepinephrine
Three protective membranes that surround the brain and spinal cord.
What are the meninges
The gaps between Schwann cells in the myelin sheath.
What are the Nodes of Ranvier
Returns the body to normal after the fight or flight response (homeostasis).
What is the parasympathetic nervous system
Neurotransmitters pass through here
What is the synapse
