Document Summary

Histology can be divided into two important categories: Medical histology is the identification of tissues and cells from microscopic slides. Dynamic histology is an extension where, along with the identification of these tissues, we examine the functions of the cells and molecules that make up the tissue. Systemic human anatomy involves observations at the macroscopic level with the eyes only, while histology takes place at the microscopic level with the use of sections and slides. These sections can be made up of various tissue combinations including epithelial, muscular, connective and nervous tissue: it is the different composition of these tissues that defines each particular section. Take the following cross section of an arm, for example: The skin is an organ made up of epithelial and connective tissue. The fascia, tendons and aponeurosis are structures made of connective tissue. The muscle is an organ made of muscular tissue. The bone is an organ and tissue made of connective tissue.
