Pulse

pulse

(Science: cardiology, physiology) The impulse transmitted to arteries by contraction of the left ventricle of the heart.

Customarily palpated at the radial artery in the wrist. The pulse can provide information concerning the number of cardiac contractions per minute (rate) and the overall regularity of the contractions (rhythm). The rhythmic contraction and expansion of the arteries with each beat of the heart; he could feel the beat of her heart.The rate at which the heart beats; usually measured to obtain a quick evaluation of a persons health.Edible seeds of various pod-bearing plants (peas or beans or lentils etc.).The 'beat' of blood that can be seen on blood vessels lying close to the skin when the left ventricle of the heart contracts to pump blood around the body.

It is the expansion and elongation of the arterial wall imparted by the column of blood and is passively produced by the pressure changes during ventricular systole and diastole.

incorrectly using paired t-test for comparing pulse rates?

... No one else in my class has done a t-test so either the whole class is wrong or I am right :shock: General idea in the lab: 1. We measured the pulse rates at different times to see how it changed when we placed our faces underwater(dive reflex). 2. We then measured the pulse rates while holding ...

Learning tissue culture, specifically moDC generation

... cells with them, maybe just leave them on the plate and add the to-be-stimulated cells to the well along with antigen (or alternatively first pulse the DCs with antigen for 4 hours in +37C and wash). The cells are stuck quite firmly to the plate, so harvesting may break some of them. Use of ...

Re: Sound and how the brain reacts to it

... if it has to do with the actual amount of energy a person is expending to complete the action? Perhaps I am getting some sort of electric pulse or backwash from them??? Or is that just weird?
