ALREADY GRADED A+ 2025 – 2026
Double product is the product of what 2 factors? -
ANSWERS-Heart Rate and Systolic Blood Pressure
True or False. Enhanced blood flow to skeletal muscle is the
only way to increase muscle VO2. - ANSWERS-False
The major metabolic substance that vasodilates blood
vessels is - ANSWERS-NO or nitric oxide
The _________ wave is the electrical repolarization of the
ventricle. - ANSWERS-T
If the ST segment is elevated or depressed this may mean
there is _______ to the heart. - ANSWERS-ischemia
,How does endurance training reduce the amount of
myocardial damage from a heart attack? - ANSWERS-
Increased antioxidant protection, Improved function of ATP-
sensitive potassium channels, and also collateral circulation
If one exercises to much or at too high and intensity this can
compromise the immune system and is known as the: -
ANSWERS-open window theory
True or False. The difference between the central and
peripheral nervous system depends
on the direction of the impulses toward and away from the
target tissue. - ANSWERS-False
What are EPSP's and IPSP's and explain how they both
influence resting membrane potential. - ANSWERS-
Excitatory post-synaptic potentials depolarize the resting
membrane potential towards the threshold.
Inhibitory post-synaptic potentials hyperpolarize the resting
membrane potential away from the threshold.
What is temporal summation? Give an example. -
ANSWERS-The input of more frequent impulses from a
,single neuron to increase EPSP's to reach an action
potential. An example is a nerve firing more frequently to
cause an action potential.
What is spatial summation? Give an example. - ANSWERS-
The input of stimuli from different neurons to result in many
EPSP's to reach an action potential. An example is having
multiple nerves send EPSP's to make a group of motor units
within the muscle to fire.
Receptors that provide the CNS with information about
position of body parts are: - ANSWERS-proprioceptors
The term which means conscious recognition of body parts
position with one another is known as - ANSWERS-
kinesthesia
List the three sensory receptors that are involved with the
above question. - ANSWERS-free nerve endings, golgi-type
receptors, pacinian corpusles
Sensory receptors which are sensitive to metabolic
chemicals are called - ANSWERS-chemoreceptors
, The name of the length-pressor sensor within the muscle is
called - ANSWERS-muscle-spindle
What is reciprocal inhibition? - ANSWERS-Activation of an
agonist muscle and inhibition of antagonist muscle on the
same side of body.
Define a "motor unit" - ANSWERS-A motor neuron and all of
the fibers that it innervates.
What does the term "ipsilateral" mean? - ANSWERS-neural
influence occurring on the same side of the body
When a muscle shortens it puts strain on a receptor known
as __________ which is not located within the muscle. -
ANSWERS-golgi tendon organ
The area within the inner ear responsible for maintaining
general equilibrium is the - ANSWERS-vestibular apparatus
The initial drive for performing a voluntary movement
occurs in the _____ of the brain. - ANSWERS-cortical &
subcortical areas
