[2] [3] Conditions treated include sunburn, insect bites, poison ivy, poison oak, and other mild skin conditions. [4] [5] It may also help dry out secretions resulting from skin irritation. [1]
In terms of cell type, the body contains hundreds of different types of cells, but notably, the largest number of cells contained in a human body (though not the largest mass of cells) are not human cells, but bacteria residing in the normal human gastrointestinal tract.
The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [13] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...
5-DHT or DHT is a male reproductive hormone that targets the prostate gland, bulbourethral gland, seminal vesicles, penis and scrotum and promotes growth/mitosis/cell maturation and differentiation. Testosterone is converted to 5-DHT by 5alpha-reductase, usually with in the target tissues of 5-DHT because of the need for high concentrations of ...
Calcium is the most abundant mineral in the human body. [3] The average adult body contains in total approximately 1 kg, 99% in the skeleton in the form of calcium phosphate salts. [ 3 ] The extracellular fluid (ECF) contains approximately 22 mmol, of which about 9 mmol is in the plasma . [ 4 ]
Depending on how calomel was administered, it affected the body in different ways. Taken orally, calomel damaged mainly the lining of the gastrointestinal tract. Mercury salts (such as calomel) are insoluble in water and therefore do not absorb well through the wall of the small intestine.
The human body consists of biological systems, that consist of organs, that consist of tissues, that consist of cells and connective tissue. The history of anatomy has been characterized, over a long period of time, by a continually developing understanding of the functions of organs and structures in the body.
The carotid body is situated on the posterior aspect of the bifurcation of the common carotid artery. [3] The carotid body is made up of two types of cells, called glomus cells: glomus type I cells are peripheral chemoreceptors, and glomus type II cells are sustentacular supportive cells. Glomus type I cells are derived from the neural crest. [4]
