Describe what happens
during repolarization of a
neuron.
Restoration of the
difference in charge
between inside & outside
of membrane (K+ outside,
Na+ inside)
Where does continuous
conduction of action
potentials occur?
Unmyelinated axons
What hollow structures
circulate cerebrospinal
fluid through the brain?
Ventricles (Lateral-thirdaqueduct-fourth)
List the structures
involved in a reflex arc in
order.
Receptor, sensory neuron,
integration center, motor
neuron, effector
In a quadriplegic, what
region of the spine is
injured? In a paraplegic?
Quad cervical; Para below
cervical
Define accommodation.
Automatic adjustment of
the lens (to change from
close to distant vision)
Auditory receptors for
sensations are found
where?
Organ of Corti on basilar
membrane in cochlea of
inner ear
What inner ear structure
maintains balance during
rotation?
Semi-circular canals
What are the names of the
auditory ossicles of the
middle ear?
Stapes, incus and malleus
Define otoliths.
Particles of calcium
carbonate found in the
inner ear that are used to
maintain balance.
Describe the function of
the circulatory system.
Transport, protection and
maintenance of
temperature
Describe the QRS section
of an EKG and what it
represents.
Ventricular depolarization
Trace the path of an
action potential through
the heart.
SA node-AV node-bundle
of His-branches-Purkinje
fibers
Pulmonary arteries carry
blood where in relation to
the heart?
Away from (to the lungs)
Define aneurysm.
Bulge in an artery; artery
weakens and can fill with
blood
Give four examples of
substance that can act as
antigens.
Bacteria, pollen, food and
viruses
What is the difference
between cell-mediated
and humoral immunity?
Cell-mediated produces T
cells; humoral produces B
cells and antibodies
Describe the difference
between the first and
second encounter with an
antigen in terms of
antibodies.
1st takes days to build
antibodies; 2nd is intense
and rapid
What is the body’s 1st line
of defense in terms of
immunity?
Physical barriers-skin,
mucous membranes, hair,
sweat, saliva, tears,
gastric juices
What is immunological
tolerance?
The body’s ability to
recognize self-cells and
therefore NOT attack
them.
Describe Boyle’s Law in
relation to pulmonary
ventilation.
It is inversely proportional;
increase in
volume=decrease in
pressure (and vice-versa)
List the components of
glomerular filtrate.
Glucose, amino acids,
urea
Describe the process of
digestion.
Digestion is the process of
breaking down food into
molecules that are small
enough to enter body cells
List the end products of
digestion.
Monosaccharides, amino
acids, glycerol and fatty
acids
What are the functions of
the large and small
intestines in the digestive
tract?
Large- absorb water and
eliminate waste from body;
small-absorb nutrients and
minerals from food
