What is muscle treppe?
•Increased contraction in response to multiple stimuli of same strength
How does increase venous return increase heart rate?
Increase in Venous returns increases end diastolic volume (EDV). This increase in volume stretch the atrial and ventricular walls. This also stretches the SA nodal fibers and AV nodal fibers triggering a homeostatic response to increase heart rate by up to 15-30% depending on individual and other factors.
What are prostoglandins?
Prostoglandins are chemical mediators. These are released from mammalian cells and effect the cells in their immediate viccinity. They produce what's known as an inflammatory response. Prostoglandins are found in cell membranes, they are released due to injury. They cause the dilation of small arteries and arterioles and increase the permeability of the capillaries. They affect neurotransmitters and blood pressure and hence pain sensation.
Definition of arterial hyperemia?
Hyperaemiaorhyperemiais the increase of blood flow to different tissues in the body. It can have medical implications, but is also a regulatory response, allowing change in blood supply to different tissues throughvasodilation. Clinically, hyperaemia in tissues manifest aserythema, because of the engorgement of vessels with oxygenated blood.[1]Hyperaemia can also occur due to a fall in atmospheric pressure outside the body.
How does caffeine affect the heart?
Well, caffeine (like most pyschoactive drugs) exerts its effect on us by altering the activity of some of our neurotransmitters. Neurotransmitters are the nervous system's way of conveying messages between neurons, and also to muscle tissue. Some neurotransmitters that caffeine is known to increase the activity of are norepinephrine, dopamine, and serotonin. The increase in norepinphrine is likely what causes the heart rate to increase, however each of these neurotransmitters has some stimulatory effects. Norepinephrine, however, is a powerfully stimulating neurotransmitter; it is associated with the 'fight or flight' response, which of course includes an increased heart rate. Caffeine can also cause ectopics (extra beats) in the heart if you have too much
What increases as you exercise?
Many things including the short term/acute effects of exericse and the Long term effects which are;Musculoskeletal response: increased blood supply; increase in muscle pliability; increased range of movement;muscle fibre micro tearsEnergy systems: phosphocreatine; lactic acid; aerobic; energy continuum; energy requirements of differentsport and exercise activitiesCardiovascular response: heart rate anticipatory response; activity response; increased blood pressure;vasoconstriction; vasodilationRespiratory: increase in breathing rate (neural and chemical control); increased tidal volumeCardiovascular system: cardiac hypertrophy; increase in stroke volume; increase in cardiac output, decreasein resting heart rate; capillarisation; increase in blood volume; reduction in resting blood pressure; decreasedrecovery time; increased aerobic fitnessMuscular system: hypertrophy; increase in tendon strength; increase in myoglobin stores; increased numberof mitochondria; increased storage of glycogen and fat; increased muscle strength; increased tolerance tolactic acidSkeletal system: increase in bone calcium stores; increased stretch in ligaments; increased thickness of hyalinecartilage; increased production of synovial fluidRespiratory system: increased vital capacity; increase in minute ventilation; increased strength of respiratorymuscles; increase in oxygen diffusion rateEnergy systems: increased aerobic and anaerobic enzymes; increased use of fats as an energy source(taken from a website - not my own work)
What are two body processes that would change in response to an increase in muscle activity?
That would be increased respiration and increased oxidation. .
Which process results in increased blood pressure in response to hormone release?
myogenic mechanism
What response should blood pressure have to an acute bout of exercise?
It should increase high blood pressure
Which activities is not increase during symphathetic response?
The two activities that are not increased during symphathetic response are abstract and methods. These are the too main ones.
What is a normal response of the integumentary system to an increase in body temperature?
Normal response to increased body temperature is sweating by sweating . It results in lowering of temperature .
Anticipated effect on blood pressure and the physiological basis of the response to high-salt diet?
Increased blood pressure. This is due to increased sodium in the blood, increasing the total extracellular fluid volume
What regulatory mechanisms would occur in response to a sudden increase in blood pressure?
Sudden vasodilation
Why does prolonged stress often result in an increase in illenesses?
Chronic or prolonged stress often results in increased blood pressure and lowering of the immune response. This, in turn, increases the stressed persons chances of becoming more susceptible to illness.
The central chemoreceptors will increase their firing rate in direct response to increases in the level of in the CSF resulting in ventilation?
carbon dioxide; increased
What caues increased lymphocytes and is it harmful?
As with anything, too much is bad. Lymphocytes increase in response to an infection. A run-away increase may reflect some bad disease.
Does your blood pressure drop during a cluster headache or raise?
During a cluster headache attack, it is more likely to see increased blood pressure than decreased blood pressure. The pain and anxiety of an attack causes a physiological response that results in stress and increased BP.
