Anatomy Midterm

Anatomy Study of the structure of the Body
Physiology study of the function of the body
Gross anatomy study of the body with the naked eye
microscopic anatomy requires the use of a microscope
cytology study of cells
histology study of tissues
systematic all organs with related functions studied together
regional all structures in a single region are studied regardless of function
pathological deal with the structure changes in cells, tissues, and organs, caused by disease
topographical study of shapes and marking called landmarks on the surface of the body
superior toward the head or upper part of the structure
inferior away from the head end or towards the lower part of the structure
anterior toward or at the front of the body
