Fully Solved 100%; Simon Fraser University 2025-2026
The brain and spinal cord lie within the region of the
CNS
nervous system, referred to as the that is
responsible for signal integration
The action potential from pain receptors can be
Local Anesthesia suppressed by chemicals injected near a sensory
receptor or nerve. This results in a reduction in pain
sensation and is an example of _.
The rods and cones are sensory retina that respond to
Photoreceptors
light; these type of receptors are known as _.
The lens of the eye is supported by attached to suspensory
Cillary Muscles ligaments. When
these smooth muscles are contracted, the lens relaxes
to focus the light from close objects on the retina.
When focusing on a close object, the ciliary muscles
Accommodation
contract resulting in a relaxation of the lens and
greater light refraction. This process is known as
______________________________________________.
When you rub your elbow after banging it against a wall, the
Gate-control Theory stimulation of the
sensation of touch reduces the pain sensation. This is
due to an inhibition of the pain signal and is
described as the _____of pain.
Blood vessels enter and exit the eye at the optic disk;
Blind Spot this is also where the optic nerve forms and exits the
eye. As there are no photoreceptors in this region it
is called a __ _.
The tips of the cochlear hair cells are imbedded in the rigid
Tectorial non-moving _____________ membrane. The contrasting
movement of the other end of the hair cells that are
attached to the basilar membrane results in
stimulation.
, Lipid derived hormones such as steroid hormones bind to
Nuclear
__________________________________________ receptors
located inside the cell.
The adrenal cortex releases the mineralocorticoid that stimulates
Aldosterone
the
kidneys to retain sodium and excrete potassium.
Releasing and inhibiting hormones from the
Portal System hypothalamus are transported in the hypothalamic-
pituitary____________ , a series of capillary beds that
then bathe the
anterior pituitary.
Protein chemical signals bind to a specific on membrane bound
Receptor Site
proteins to
initiate a response.
Cortisol is released from the under stimulation from releasing
Adrenal Cortex hormones from
the anterior pituitary. Cortisol acts during stress to
provide energy sources for tissues and also reduces the
inflammatory (swelling) response.
Epinephrine is release from the ___ in response to sympathetic
Adrenal Medulla
nervous system stimulation.
