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
what is the pneumonic to remember the function of the cerebellum
My Boy Moves
what is the function of the Pons
Control breathing, hearing, taste, balance
what is the pneumonic to remember the function of the pons
Come Brad, The Beers Here
what does the forebrain consist of
Cerebrum, thalamus, hypothalamus
cerebrum functions
initiate movmeent, temperature, touch, vision, hearing, judgement, reasoning, problem solving
what is the pneumonic to remember the cerebrum functions
Really, The Very Movment That Happens Just, Physically Troubling
what is the function of the Thalamus
Relay message from LOWER BRAIN and CEREBRAL CORTEX
what is the function of the Hypothalamus
Emotion/reward, Endocrine, eating
what is the pneumonic to remember the functions of the hypothalamus
Really, Even Evan Eats
what are the 4 lobes of the brain
Frontal, Parietal, Occipital, Temporal
what is the front lobe responsible for
short term/working memory, information processing, decision making, planning, judgement
what is the parietal lobe responsible for
sensory input, spatial positioning
what is the occipital lobe responsible for
visual input
what is the temporal lobe responsible for
auditory input
what does the cerebellum do
coordinate movement, support memories
what is the function of the brainstem
regulate respirtaory, digestive, circulatory function
what does the brainstem include
midbrain, medulla oblongota, pons
what are the 3 parts of the midbrain
tectum, tegmentum, ventral tegmentum
what is the function of the midbrain
hearing, vision
what is the function of the pons
respirtatory control, hearing, taste, smell
what is the pneumonic to remember the function of the pons
Here’s The Real Cool Surfers
What is the function of the autonomic nervous system
Maintain homeostasis of the body: control internal organs, blood vessels, smooth muscle tissue, glands
what controls the Autonomic Nervous System through the brainstem
hypothalamus
function of the sympathetic nervous system
Fight or flight!!!
function of the parasympathetic nervous system
rest and digest!!!
what does efferent mean
motor neuron (controls functions)
what does afferent mean
sensory neuron
efferent nerves
bring signals from central nervous system to sensory organs/muscles
afferent nerves
bring signal from organs and muscle to central nervous system
what does the somatic nervous system do
controls 5 senses// voluntary movement of skeletal muscle
