Brown fat cells or plurivacuolar cells are polygonal in shape. Unlike white fat cells, these cells have considerable cytoplasm, with lipid droplets scattered throughout. The nucleus is round, and, although eccentrically located, it is not in the periphery of the cell.hite fat cells or monovacuolar cells contain a large lipid droplet surrounded by a layer of cytoplasm. The nucleus is flattened and located on the periphery. A typical fat cell is 0.1mm in diameter with some being twice that size and others half that size.
When someone refers to resting pulse rate, it often means the rate at which the heart beats when the body is at rest. Resting pulse rates within a normal range is an indication of good health, asserts the National Institutes of Health. For women, a normal resting heart rate isn't different than in a man. The National Institutes of Health state that 60 to 100 beats per minute is considered normal for a resting pulse rate. Any female over 10 years of age should fall within this resting pulse rate range, unless they are well-trained athletically.
The normal resting adult human heart rate ranges from 60â100 bpm. Tachycardia is a fast heart rate, defined as above 100 bpm at rest. Bradycardia is a slow heart rate, defined as below 60 bpm at rest. During sleep a slow heartbeat with rates around 40â50 BPM is common and is considered normal.radycardia was defined as a heart rate less than 60 beats per minute when textbooks asserted that the normal range for heart rates was 60â100 BPM. The normal range has since been revised in textbooks to 50â90 BPM for a human at total rest.
