What is the type of contraction in which the muscle fibers produce increased tension but does not shorten?
An isometric contraction builds tension but there is no joint movement.
When the temperature of ice is increased slightly. Does it undergo a net expansion or net contraction?
Net Contraction
What stimulates adh secretion from the posterior pituitary?
increased plasma osmolality
What hormone stimulates increased production of gastric juice?
Gastrin.
What stimulates vaso dilation?
Vasodilation is a mechanism for thermoregulation . It is used for cooling down body temperature . Increased body temperature stimulates vasodilation .It results in increased blood flow to skin to aid heat dissipation .
Why do Beta agonist cause hypokalemia?
Beta 2 adrenergic agonists cause increased potassium entry into cells, which can lead to hypokalemia
When the temperature of ice cold water is increased slightly does it undergo a net expansion or net contraction?
net contraction
What is activation energy and how does it relate to cell metabolism?
activation energy is the amount of energy that is required for a reaction to start. Enzymes lower activation energy allowing metabolism to go at increased rates.
Why do beta 2 agonists cause hypokalemia?
