Endocrinology
This hormone is released by the pancreas when plasma glucose levels are low
Glucagon
The speed of cellular chemical reactions is regulated by catalyst called
Enzymes
Which blood vessel is composed of one cellular layer and functions to exchange nutrients and waste materials between blood and tissues?
Capillaries
Newton’s Law indicating for every force, there is an equal and opposite reaction.
Newton's third law
consists of one alpha motor neuron and all the extrafusal muscle fibers it innervates
This class of hormones are lipid soluble, pass through cell membranes and bind to receptors within the cell.
Steriod
this enzyme is the rate-lmiting step of glycolysis
phophofructokinase
Last functioning pacemaker of the heart (when there is no SA or AVN nodes)
Purkinje fibers
This is the pattern or sequence of joint motion without consideration of forces
Kinematics
Two main fuctions of motorneruon pool to produce force
Motor unit recruitment and firing rate
This hormone is released by the posterior pituitary gland and increases water reabsorption in the kidneys
ADH (vasopressin)
Rate limiting enzyme of citric acid cycle
isocitrate dehydrogenase
Highest sustainable work rate without progressively increasing blood lactate concentration
Maximal Lactate Steady State (MLSS)
This is the time between eccentric and concentric actions.
amortization phase
What part of the muscle cell allows an action potential to spread uniformly throughout the cell
T-tubules
This class of hormone cannot cross the cell membrane and relies on secondary messengers
non-steriod
These reactions are reactions that are linked, with the liberation of free energy in one reaction being used to "dirve" a second reaction.
coupled reaction
What effects venous return to the heart? three answers
1. Skeletal muscle pump
2. Respiratory pump
3. vasoconstriction
This point marks the amount of transitional deformation indicating a shift from elastic to plastic.
Yield Point
An experimental drug is given to a patient. The drug is known to inhibit the activity of acetylcholinesterase. What effect would most likely be observed in the patient as a result of this drug?
Induce muscle contractions
The increase in number of cell receptors; more hormone can bind to the cell and lower concentrations of the hormone remain in the blood plasma
Up-regulation
The difference between oxygen uptake in the first few minutes of exercise and an equal time period after steady state has been obtained
o2 deficit
In a 12-lead ECG inverted t waves/ST depression is representative of what condition
Ischemia
This type of deformation allows an object to return to its original dimensions post disturbance.
Elastic deformation
At the neuromuscular junction, receptors respond to neurotransmitters to facilitate the depolarization of muscle cell membranes. This is the first step in that muscle cell's ultimate contraction. Which types of receptors would be most likely found on the muscle cell, directly interacting with the neurotransmitter at the neuromuscular junction?
Nicotinic ligand-gated channels
