Down Flashcards
The stage of action potential where sodium ions begin to move into cell
Depolarization
A neurotransmitter released by the sympathetic nervous system to induce the fight or flight response
Noradrenalin
WHAT carry nerve impulses away from CNS
Motor/efferent
A type of neuron found only in the CNS
Interneuron
The portion of the cerebrum responsible for understanding speech
Parietal lobe
The portion of the nervous system which puts you into a lore relaxed state
Parasympathetic
The stage of action potential where potassium ions begin to move out of cell
Repolarization
The name given to the “nerve impulse” that passes along a neuron
Action potential
WHAT contains all the nerves that effect the skeletal muscles and sensory organs
The somatic nervous system
Portion of the nervous system that is not the CNS
Peripheral
The portion of the brain that receives all information from the senses (except smell)
Thalamus (decides where to send it)
An involuntary response which bypasses the brain
Reflex
A substance which costs the axons of nerve cells
Myelin
The part of the brain responsible for conscious thought
Cerebrum lobe
The “master gland”
Pituitary
WHAT occurs because of the myelinated nature of the axon
Saltatory transmission
These substances break down neurotransmitters in the synaptic cleft after their release
Enzymes
The part of the brain responsible for balance
Cerebellum
A horizontal section that connects the right and left hemispheres of the brain
Corpus Callosum
WHAT make the post synaptic membrane less permeable to sodium and therefore less likely to produce action potential
Inhibitory transmitter
The live of the cerebrum responsible for hearing and smelling
Temporal lobe
WHAT in the spinal cord contains bundles of myelinated axons
White matter
How many pairs of spinal nerves do we have
31
WHAT in the spinal cord contains mostly cell bodies
Grey matter
The sodium/potassium pump requires the energy molecule
ATP
