Science - Nervous System Flashcards
neurons
cells that carry electrical impulse and COMMUNICATE to other ORGANS
action potential
neuron reaching a point that CREATES STIMULATION
chemical synapse
stimulate/inhibit action of another cell
sensory neurons
transmit signals to central nervous system (CNS) from sensory receptors
what are sensory neurons responsible for
touch, pain, temperature, hearing, sight, smell, taste
what is the pneumonic to remember sensory neuron responsibilities
The Take Home iS, See Trees: Touch Taste Hearing Smell Sight Temperature
what do MOTOR NEURONS do
transmit signals from central nervous system to the whole body:Signals muscles and glands
interneurons
transmit signals between neurons
dendrites
RECEIVE impulse from sensory receptors or interneurons// transmit toward cell body
where is the nucleus contained in a neuron
cell body
what does an AXON do
transmit impulse away from cell body
oligodendrocytes
insulates myelin sheath
nodes of ranvier
gaps in myelin sheath
what are the 3 parts of the brain
hindbrain, midbrain, forebrain
what does the midbrain consist of
medulla oblingota, cerebellum, pons
what is the pneumonic to remember what the midbrain consists of
Com Please Me
what is the function of the medulla oblingota
regulates breathing, heart function
what is the pneumonic to remember the function of the medulla oblingota
He Really Breathes
what is the function of the cerebellum
voluntary movement, balance, memories
