1
The basic building blocks of the nervous system are
.
2
brief electrical charge that travels down the axon
3
junction between the axon tip of the sending neuron & the
dendrite or cell body of the receiving neuron is
.
4
natural, opiate-like neurotransmitters linked to pain control
& to pleasure.
5
The peripheral nervous system is connect to your brain and
your brainstem, which is also known as
.
6
When excitatory signals minus inhibitory signals exceed a
minimum intensity, called the
, they trigger an action
potential.
7
the sensory & motor neurons that
connect the central nervous
system to the rest of the body
8
division of the peripheral nervous
system that controls the body’s
skeletal muscles
9
part of the peripheral nervous
system that controls the glands
& muscles of the internal
organs
10
division of the autonomic
nervous system that arouses
the body, mobilizing its energy
in stressful situations
11
simple, automatic, inborn response
to a sensory stimulus, such as the
knee-jerk response
12
What’s this?
The
is a extension of a neuron, ending in
branching terminal fibers, through which
messages pass to other neurons or to muscles or
glands
?????????
13
What are the bushy,
branching extensions of a
neuron that receive
messages & conduct
impulses toward the cell
body?
14
What are the chemical
messengers that traverse
the synaptic gaps between
neurons. (Don’t be
specific.)
15
The neurotransmitter that enables learning & memory & also
triggers muscle contraction. (Be specific.)
16
neural “cables”
containing many axons
17
body’s speedy,
electrochemical
communication network,
consisting of all the
nerves of the peripheral &
central nervous system
Hint: its about the big
picture.
18
Cortex at the front of the parietal lobes that registers & processes
body touch & movement sensations
19
area at rear of frontal lobes that controls voluntary movements
20
areas of the cerebral cortex that are not involved in primary motor or
sensory functions; rather, they are in higher mental functions such as
learning, remembering, thinking, & speaking
21
controls’ language
expression—an area
of the frontal lobe,
usually in the left
hemisphere, that
directs the muscle
movements involved
in speech.
22
portion of cerebral cortex lying roughly above the ears;
includes auditory areas, each of which receives auditory
info primarily from the opposite ear
23
What’s this?
portion of cerebral cortex lying at back of head; includes the
visual areas, which receive visual info from the opposite visual
field
24
What is the
orange lobe?
portion of cerebral cortex
lying at the top of the head
& toward the rear;
receives sensory input for
touch & body position
25
What’s
this?
portion of the cerebral
cortex lying just behind
the forehead; involved in
speaking & muscle
movements, & in making
plans & judgments
26
What’s this?
brain’s sensory
switchboard, located on
top of the brainstem;
directs messages to the
sensory receiving areas in
the cortex & transmits
replies to the cerebellum &
medulla
What’s this?
27
neural structure lying
below the thalamus; it
directs several
maintenance activities
(eating, drinking, body
temp), helps govern the
endocrine system via the
pituitary gland, & is linked
to emotion
28
2 lima bean-sized neural
clusters that are
components of the limbic
system & are linked w/
emotion
What is this?
29
This thingy…
the large band of neural fibers connecting the 2 brain
hemispheres & carrying messages between them
30
What is this?
oldest part & central core of the brain, beginning where the spinal
cord swells as it enters the skull; the
is for
automatic survival functions
31
intricate fabric of interconnected
neural cells that covers the
cerebral hemispheres; the
body’s ultimate control and infoprocessing center
32
“little brain” attached to
the rear of the brainstem;
its functions include
processing sensory input
& coordinating
movement output &
balance
What is this?
Not this!!
