6- The oldest anatomical drawing-- Egyptian
papyrus written 16 centuries ago - Shows that the heart, vessels, liver, spleen,
kidneys and bladder were recognized, and that the

7Aristotle (384 - 322 B.C.), 1st noted to study
animal carcasses to compare them to human bodies
8300 B.C Herophilus Erasistratus performed

91752Englands Murder Act passed
the medical dissection of all executed murderers.
101832Anatomy Act allowed use of unclaimed bodies

prison or the workhouse
11Since King Henry V111 (1509)
- Murderers, prisoners, prostitutes, people unable
to pay for their burials, those that committed
suicide were approved for human anatomy studies
1217-19th centuryBody snatching!!!
- Not enough corpses for medical students so many
times freshly dug graves were excavated for

caught.
13Dissection is the process of disassembling
something to determine its internal structure
as an aid to determining the function
relationships of its components.
14Vivisection refers to the dissection of living
animals
15Dissection is often performed as a part of
determining a cause of death in autopsy (on
humans) and necropsy (on animals) and is an
intrinsic part of forensic medicine, such as
would be practiced by a coroner.

27Anatomical Planes of the Body
- Medical professionals often refer to sections of
the body in terms of anatomical planes (flat
surfaces). - These planes are imaginary lines vertical or
horizontal drawn through an upright body. The
terms are used to describe a specific body part
(area).

31Proximal
32Caudal
- Referring to the lower part of the body or tail
