nervous system
continuously sends and receives messages from your body in order to manage critical functions
brain, spinal cord, nerves
three parts of the nervous system
brain
receives sensory input from spinal cord and nerve cells, controls functions
spinal cord
provides sensory information to the brain
nerves
bundles of nerve cells, or neurons that transmit impulses (messages) from your body to brain and from your brain to cells of body
brain
organizes and processes information for your body
brain
The ______ is responsible for memory and coordination.
cerebrum, cerebellum, brain stem
three parts of the brain
cerebrum
What is the largest part of the brain?
cerebrum
The _______ allows memory, comprehension, and emotion.
right, left
In the cerebrum, the left side of the brain controls the ______ side of the body, right controls the ______.
frontal, parietal, temporal, occipital
What are the four lobes of the brain?
frontal lobe
controls motor and high order functions
parietal lobe
visual perception, comprehension (pain, touch, temperature)
temporal lobe
emotion, speech, hearing
occipital lobe
vision, colors
cerebellum
moves muscles, receives info from cerebrum
muscle memory
What term is associated with the cerebellum?
brain stem
controls breathing, digesting food, circulating blood, and involuntary muscles
four
How many regions of the brain stem?
between brain hemispheres
Where are the diencephalons?
thalamus, thalamus
The diencephalons contain both the hypo______ and ______.
below
hypo=
thalamus
relay center for sensory impulse (excluding smell)
hypothalamus
regulates sleep, hunger, thirst, body temperature, pressure, homeostasis
midbrain
located below diencephalons, joins cerebrum and spinal cord, relays signals between spinal cord and cerebrum and cerebrum and cerebellum
pons
below midbrain, joins cerebellum with cerebrum and left and right hemispheres, sends info between hemispheres and between cerebrum and cerebellum
medulla oblongata
SPINAL CORD!, controls heartbeat, breathing, and blood pressure
below
The pituitary gland is located ______ the hypothalamus.
spinal cord
The ______ ______ connects the brain and PNS.
31
How many pairs of spinal nerves are there?
Ascending Nerve Tract
carries information from body's muscles to the brain
Descending Nerve Tract
carries information from the brain to the body's muscles
spinal cord
What does cerebrospinal fluid bathe?
fibers, neurons
Nerves are made up of nerve ______ and bundles of ______.
neurons
specialized cells that send and receive messages (nerve impulses)
nucleus
controls cell and produces messages sent to the CNS
dendrites
receives impulses and sends them to cell body
axons
transmit impulses away from cell body
synaptic terminal
transmits impulses other neurons or muscle glands
synapse
between two neurons, between neuron and muscle
axon
tail=
terminal
end of tail=
motor neuron
activates muscles and glands
sensory neuron
detects environment
interneuron
connects everything
NO
Does the brain ever rest?
7
How many discrete items can the average brain hold at once?
nerves
What is included in the peripheral nervous system (PNS)?
brain, spinal cord
What is included in the central nervous system (CNS)
sensory impulses
messages taken in by the body that inform the nervous system about what's going on both inside and outside the body
motor impulses
messages sent to your body to control activities like walking, breathing, digestion, and talking
somatic, autonomic
What are the two parts of the PNS?
12, 31
The somatic system includes __ pairs of cranial nerves and __ pairs of spinal nerves.
internal
The autonomic system regulates the body's ______ environment.
senses
What do the CNS and PNS work together to receive (you have 5 of them)?
above kidneys
Where is the adrenal gland located?
fight, flight, or freeze
What is the adrenaline response called?
optic nerve
What connects the eye to the nervous system?
occipital lobe
What lobe of the brain does the optic nerve connect to?
vestibulocochlear
What is the ear connected to?
temporal lobe
What part of the brain is the vestibulocochlear connected to?
olfactory
What connects the nose to the nervous system?
glossopharyngeal
What connects taste to the nervous system?
touch neurons
What gives us a sense of touch?
parietal lobe
What part of the brain senses touch?
temperature, pain, pressure
What does your sense of touch detect?
True
True or false; we don't know a majority of information about the brain?
auntonomic nervous system
nerves that carry involuntary impulses to smooth muscle, cardiac muscle, and various glands
central nervous system
the portion of the vertebrate nervous system consisting of the brain and spinal cord
axon
long fiber that carries impulses away from the cell body of a neuron
cerebrospinal fluid
a solution that fills the hollow cavities of the brain and circulates around the brain and spinal cord. Provides nourishment, cushions, and removes wastes
dendrites
branching extensions of neuron that receives messages from neighboring neurons
electroencephalogram (EEG)
a graphical record of electrical activity of the brain
interneurons
neurons that carry outgoing information from the central nervous system to the muscles and glands
neuron
a nerve cell; the basic building block of the nervous system
peripheral nervous system
the sensory and motor neurons that connect the central nervous system to the rest of the body
sensory neurons
neurons that carry incoming information from the sense receptors to the central nervous system
synapse
the junction between two neurons (axon-to-dendrite) or between a neuron and a muscle
