Science 3rd Quarter Flashcards
dendrites
picks-up messages from the environment and carry them towards the cell body
nucleus
is the control center of the cell, it maintains the cell and keeps the neuron functioning
axon
function is to carry signals away from the cell body to the terminals buttons to transmit electric signals to other neurons
myelin sheath
increases the speed of the signal
cell membrane
protects the cell
axon hillock
generates impulse in the neuron
axon terminal
transmits messages to other cells
node of ranvier
allows diffusion of ions
schwann cell
protects the myelin sheath
cell body
organizes and keep the cell functional
hypothalamus
maintains homeostasis, regulates body temperature, thirst, hunger, appetite and emotions
thalamus
above the brain stem, relay station for sensory and motor signals
cerebrum
is the largest part of the brain that controls memory, planning, reasoning, intelligence, verbal ability and mathematical ability.
cerebellum
connects the medulla oblongata to the cerebrum, also controls the rate of breathing
brainstem
controls the breathing, digestion, circulation
parietal lobe
sensory information
temporal lobe
controls our sense of smell, speech, rhythm and our short term memory
frontal lobe
controls our personality, decision-making, physical movements
occipital lobe
located at the back of the brain, involved with our vision
spinal cord
connected to the brain stem, it sends messages from and to our body and brain
medulla oblongata
regulates breathing, heart rhythms, blood pressure, and swallowing
pons
coordinates facial movements, hearing, and balance
midbrain
regulating eye movements
