Lights, Camera, Action
The rapid temporary change in voltage across a cell's membrane that allows neurons and muscle cells to transmit signals
Action Potential
Control center of the cell, encased in a double membrane envelope
Nucleus
We estimate this many synapses in the human brain
100,000,000,000,000 (100 trillion)
The nervous system is made up of this many parts
2 (central/peripheral)
Most known for its function to create NEW memories
Hippocampus
The action potential travels through this part of the neuron
Axon
Branches connected to the main part of the cell
Dendrite
This is the specific term for the neuron that sends a signal across a synaptic cleft to its neighbor
Presynaptic neuron
Nerves in your left hand belong to this nervous system
Peripheral
The brain region that is responsible for movement and reflexes
Midbrain
Myelin sheath
At the tail of the neuron, releases neurotransmitters
Axon terminal
This microscopic gap between two neurons is where neurotransmitters like serotonin cross over to pass along a signal
Synaptic gap
The semantic functions of your nervous system include
Voluntary movements, carry sensory information, control skeletal muscles
If there is a patient in a case study who struggles with their ability to process emotions they likely are having issues with their what
Hypothalamus
The recovery portion of the action potential
Repolarization
Forms the myelin sheath to insulate axons and speed up nerve impulses (rhymes with bombshell)
Schwann cell
Known as the 'receiver' of the nerve impulse
Neurotransmitter receptor
This part of your nervous system is known for carrying out daily actions 'unconsciously'
Autonomic nervous system
This lobe of the brain is close to the ear and holds a large responsibility for healing, language, and memory
Temporal lobe
The typical amount of mV needed to cause the action potential
-70
Named after a French pathologist, these microscopic gaps in the myelin sheath of a nerve cell help speed up the transmission of electrical impulses
Node of Ranvier
Drugs do this to the neurotransmitters in your brain
Overstimulate, overproduce signals, block receptors, etc.
A quadriplegic has had damage done to this crucial part of the nervous system
Spinal cord
This SYSTEM is held inside of the outer lobes
Limbic System
