A medical monitoring device displaying a normal human heart rate. Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide.
Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block.
Because of the heart’s orientation and “suspension” in the chest, sleeping on the left side can cause subtle changes in the heart’s position, says Leonard Ganz, M.D., cardiologist and ...
Heart rate variability, well known to increase during REM, predictably also correlates inversely with delta-wave oscillations over the ~90-minute cycle. [4] In order to determine in which stage of sleep the asleep subject is, electroencephalography is combined with other devices used for this differentiation.
The Fischer–Saller scale, named after Eugen Fischer and Karl Saller is used in physical anthropology and medicine to determine the shades of hair color. The scale uses the following designations: A (very light blond), B to E (light blond), F to L (), M to O (dark blond), P to T (light brown to brown), U to Y (dark brown to black) and Roman numerals I to IV and V to VI (red-blond).
This finding has also been demonstrated in a study conducted by T. R. Alley in which he had 25 undergraduate students (consisting of 7 men and 18 women) rate the cuteness of infants depending on different characteristics such as age, behavioral traits, and physical characteristics such as head shape, and facial feature configuration.

Vellus hair replaces lanugo hair on a human fetus at 36 to 40 weeks of gestation. [2] The growth cycle of vellus hair is different from the growth cycle of terminal hair. At puberty, androgen hormones cause much of the vellus hair to turn into terminal hair and stimulate the growth of new hair in the armpit and the pubic area. In men, this ...
