temperature, and thirst, and creates feelings of pleasure. Links the nervous system to the
endocrine system via pituitary gland.
What do epinephrine and norepinephrine stimulate and what is the result? - ✔✔Simulate
the sympathetic division of ANS causing increased heart and lung activity, dilation of pupils, and
increase in blood sugar. Gives body a surge of energy to respond to a threat.
What is a reflex? How is it triggered and where is it processed? - ✔✔An involuntary and
nearly instant movement in response to a stimulus. Triggered one sensory information is
powerful enough to reach a given threshold and interneurons in the spinal cord act to send a
message through the motor neurons without relating to the brain. Processed within the spinal
column.
What is the spinal cord what is its purpose and what is contained within it? - ✔✔Long, thin,
tubular, bundle of nerves and supporting cells, extending from the brain. Central pathway of
information for the body. Contains ascending tracts of sensory neurons and descending tracts
of motor neurons.
What is an interneuron and what is its function? - ✔✔Most common type of neuron located
primarily within the CNS. Allows the brain to combine multiple sources of available information
to create a coherent picture of sensory information. Responsible for communicating among
neurons.
,What is a motor neuron and what is its function? - ✔✔A type of nerve in the central nervous
system, also called efferent neuron. Transmits information to the muscles and glands.
What is a sensory neuron and what is its function? - ✔✔Type of nerve in the central nervous
system, also called afferent neuron. Carries information from sensory receptors.
What is the amygdala? What is its primary function and what bodily system is it connected to? -
✔✔Two almond shaped clusters in the limbic system, responsible for our perceptions of an
reactions to fear. Has connections to the sympathetic nervous system..
Where are the adrenal glands located? And what are their primary functions? - ✔✔Two
triangular glands, one atop each kidney. Regulate salt and water balance in the body and
involved in metabolism, immune system, sexual development and sexual function. Secrete
epinephrine and norepinephrine.
What is the limbic system's primary purpose? Where is it located and what structures does it
contain? - ✔✔Responsible for memory, emotion, and responses to reward and punishment.
Located between the brainstem and the two cerebral hemispheres. Contains amygdala,
hypothalamus and hippocampus.
What is the responsibility of the thyroid and parathyroid glands? - ✔✔Responsible for
determining, how quickly the body uses energy and hormones, as well as controlling the
amount of calcium in the blood and bones
How are nerves differentiated ? - ✔✔According to their function.
What is the central nervous system and what is its primary function and what are its two main
components? - ✔✔Two main components are the brain and spinal cord. Interprets
information coming in from the senses, formulates an appropriate reaction and sends
responses to the appropriate system.
,Where is the pineal gland located and what does it do? - ✔✔Located in the middle of the
brain and secretes a hormone (melatonin) that helps regulate the sleep wake cycle
What is transcranial magnetic stimulation and what is its primary advantage? - ✔✔A
procedure in which magnetic pulses are applied to the brain of a living person to safely and
temporary deactivate a small brain region. Electrical stimulation is provided to the brain before
or while a participant is working on a cognitive task and effect of the stimulation on
performance is assessed. Advantage is it allows researchers to draw a causal conclusions about
the influence of brain structures on behaviour
What is functional magnetic resonance imaging and what does it produce and what are its
advantages? - ✔✔fMRI is a brain scan that uses a magnetic field to create images of brain
activity in each brain area, and to text the amount of blood flow in each brain region to indicate
neural activity. Generates clear and detailed pictures of brain structures in the form of cross-
sectional slices, and is non-invasive and area specific.
What is magnetic resonance imaging and what are its advantages? - ✔✔Procedure, that
employs magnets to change the alignment of atoms within the brain which are than energized
by a pulse of radio waves return to alignment is detected and 3-D images are created by a
computer program. Provides detailed images of brain structure.
What is computerized tomography scan and what does it produce? - ✔✔Essentially x-rays
taken around the head, that could be a combine to produce 3-D images of the brain. Least
expensive brain imaging.
Evolutionary psychology focuses primarily on ____ which are _____. These are in contrast with
____ which occur _____. - ✔✔Psychological adaptations.
Mechanisms of the mind that have evolved to solve specific problems of survival or
reproduction.

amygdala. Important in storing information in long term memory
The brain is divided, into blank, blank, and blank structures that must work together. -
✔✔Hindbrain, midbrain, and forebrain
What is the cerebral cortex and what does it allow us to do? - ✔✔-Outer bark-like layer of
our brain that is wrinkled & Folded to create a larger surface area
- Allows us to use language, acquire complex skills, create tools and live
in social groups
