What is it?
Nerve cell in the body.
Neuron.
Fatty tissue that surrounds and protects the axon.
Myelin Sheath
Central Nervous System is composed of?
Brain, Spinal Cord
The principle stating that neuron either completely fires or doesnt at all.
All or nothing
The lobe of the brain that is involved in processing auditory information is the ____________ lobe.
Temporal Lobe
The cell body of a neuron is called the ___________
Soma
Small gaps between the cells of the myelin sheath.
Nodes of Ranvier
This neuron fires after watching someone perform a movement.
Mirror
When neuron sends a brief electrical impulse down the axon.
Action Potential
The lobe of the brain that is involved in processing is the _________________ lobe.
Occipital
Extensions of a neuron that retrieves information and messages from other neurons is called the __________
Dendrites.
Holds neurotransmitters until they are ready to be used, look like little sacs.
These neurons carry information from the sensory receptors (Nose, eyes, skin, etc.)
Sensory
Reuptake.
The lobe of the brain that is responsible for registering the sensations of touch, pressure, temperature and pain and spatial orientation and mathematical reasoning.
Parietal Lobe
The long arm of a neuron that extends toward other neurons, where electrical impulses travel to carry messages to other neurons is called the _________.
Axon
The area on a dendrite where neurotransmitters attach and transmit message.
Receptors
Neurons that carry info from brain and spinal cord telling your muscles to move.
Motor
Happens when a neuron has already fired and has to recover in order to be able to fire again.
Refractory Period
Frontal
___________________ is a chemical messenger that carries signals between neurons.
Neurotransmitter
"Little Brain" Helps with balance and coordination.
Cerebellum
When a neuron is polarized, and can fire, but is not yet firing.
Resting Potential.
Regulates the body and tries to keep you in a state of homeostasis.
Hypothalamus
The part of the brain that connects each hemisphere is called the __________.
Corpus Callosum
