A prosector is a person with the special task of preparing a dissection for demonstration, usually in medical schools or hospitals. Many important anatomists began their careers as prosectors working for lecturers and demonstrators in anatomy and pathology.
The act of prosecting differs from that of dissecting. A prosection is a professionally prepared dissection prepared by a prosector – a person who is well versed in anatomy and who therefore prepares a specimen so that others may study and learn anatomy from it. A dissection is prepared by a student who is dissecting the specimen for the purpose of learning more about the anatomical structures pertaining to that specimen. The term dissection may also be used to describe the act of cutting. Therefore, a prosector dissects to prepare a prosection.
Prosecting is intricate work where numerous tools are used to produce a desired specimen. Scalpels and scissors allow for sharp dissection where tissue is cut, e.g. the biceps brachii muscle can be removed from the specimen by cutting the origin and insertion with a scalpel. Probes and the prosector's own fingers are examples of tools used for blunt dissection where tissue may be separated from surrounding structures without cutting, i.e. the bellies of biceps brachii and coracobrachialis muscle were made clearer by loosening the fascia between the two muscles with a blunt probe.
Generally, the risks to prosectors are low. Cadavers used for teaching purposes are embalmed before they are encountered by a prosector and students. Embalming fluid usually contains formaldehyde, phenol, Dettol, and glycerine which disinfect and kill pathogens within the cadaver. With exposure to embalming fluid, tissues and bodily fluids, such as blood, become fixed. Prosectors and students working with embalmed cadavers must always wear protective gloves, however this is more for protection against the harsh chemicals used in embalming such as formaldehyde and dettol which can cause moderate to severe skin irritation.
Further to the protection that embalming allows against disease, educational institutions take great care in screening the cadavers accepted into their body donation programs. Cadavers are not accepted if they have a medical history of infectious disease such as tuberculosis and HIV/AIDS.
Prosectors for autopsies of diseased cadavers may run a high risk of suffering from health problems when caution is not used as cadavers are not fixed when being dissected for autopsy. At least two diseases are named after prosectors:
- Prosector's paronychia: a primary inoculation of tuberculosis of the skin and nails.
- Prosector's wart, a skin lesion, also caused by contamination with tuberculous material
Contracting infections caused by contaminated cadavers is a constant danger among prosectors, particularly if a skin puncture accident results from the sharp surgical instruments used in this kind of work (about 70% of pathology workers report having at least one percutaneous incident). In this case, thin surgical gloves are not enough to protect. There are many cases of pathologists who died of acute septicemia (blood poisoning) because of this. Another example, a famous historical case, is that of Dr. Ernst von Fleischl-Marxow, an Austrian physician, pathologist and physiologist, who infected his finger during an autopsy and became dependent on morphine, due to the pain; and, later, on cocaine, by instigation of his friend, Sigmund Freud.
Presently, AIDS presents a problem. Although it is difficult to contract it by a single puncture incident (the overall personal risk has been estimated to be 0.11%), at least one case has been reported  among pathologists.
The continuous respiratory exposure to formaldehyde, used to preserve cadavers, is also an occupational risk of prosectors as well as medical students, anatomists and pathologists. Inhaled formaldehyde can irritate the eyes and mucous membranes, resulting in watery eyes, headache, a burning sensation in the throat, and difficulty breathing. Formaldehyde is listed as a potential human carcinogen.
