nervous Flashcards
regulate the body’s responses to internal
and external stimuli
nervous system
to connect all your body parts and transmit signals
from one another
nervous system
to send and receive messages between you and the outside world, and within
your own body.
nervous system
physical movement
nervous system
the senses
nervous system
intelligence, learning, and memory, your thoughts and feelings
nervous system
basic body functions
nervous system
efferent/motor signals target the
muscles, glands, organs
afferent / sensory signals
go from external to the brain
main processing center for the entire nervous system -consist of two mainly components:
BRAIN and the SPINAL CORD
central nervous system
to organized and distribute information
brain
activty and thoughts
cerebrum
posture, balance and coordination
cerebellum
part that connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate, and blood pressure
brain stem
moves information to and from the lobes, and controls movements and memory.
thalamus
controls appetite, thirst and body temperature. It also produces hormones that control the release of other hormones in the pituitary gland.
hypothalamus
control movement, speech and some of the functions of the mind such as behavior, mood, memory and organization
frontal lobes
play an important role in memory, hearing, speech and language
temporal lobes
play an important role in sensation and in an understanding of numbers, awareness of the body and feeling of space.
parietal lobe
process visual information from the eyes.
occipital lobe
channel for signals between the brain and the rest of the body, it can control simple musculoskeletal reflexes without input from the brain
spinal cord
are automatic responses of the body that help maintain posture and protect against injury.
simple musculoskeletal reflexes
basic unit of the Nervous System.
neuron
Central Nervous System is connected to the organs and limbs of your body through the—-
peripheral nervous system
small branch- like extensions (their name comes from a Latin word that means “tree-like”) on the cell body.
receiving point
dendrites
main part of the cell.
cell body
a long, arm-like part that extends outward from the cell body.
axon
composed of fatty chemical compounds
-surrounds the axon of many neurons and acts as a protective covering
myelin
the area where one neuron communicates with the next neuron
synapse
voluntary control
somatic
involuntary control
autonomic
fight or flight
sympatheti
rest and digest
parasympathetic
