Histology as taught in most professional schools constitutes a one year's course, but for the embalmer this is not entirely necessary and with the short term of schooling now existing it is quite impossible, but certain of the fundamental principles of histology are important. For this reason a few of the more important tissues have been discussed, not, however, in great detail, but only superficially, merely to have the embalmer acquainted with them.
A Cell.
—A cell is defined as a nucleated mass of protoplasm endowed with the attributes of life.
Protoplasm is the name applied to the semi-fluid, granular substance contained within the cell.
The simplest forms of animal life are organisms consisting of only one cell which are called protozoa.
Cells having similar shape and similar functions are grouped to form tissues.
Tissues are grouped together to form organs.
Every cell consists of a cell body and a nucleus. The cell body consists of a substance known as protoplasm. The nucleus is the essential part of a typical cell and is the controlling center of its activity.
