Ch 1 Flashcards
Deals with the form and structure of the body and its parts - what things look like and where they are located.
Anatomy
Deals with the functions of the body and its parts - how things work and what they do.
Physiology
Deals with structures so small we need a microscope to see them clearly, such as cells and tissues.
Microscopic anatomy/histology
Deals with body parts large enough to be seen with the unaided eye, such as organs, muscles, and bones.
Macroscopic anatomy/gross anatomy
The study of individual regions of the body.
Regional anatomy
The study of individual systems of the body. Deals with the systems of the body such as the nervous system and the skeletal system, as separate topics.
Systematic anatomy
Planes of reference:
A plane that runs the length of the body and divides it into left and right parts that are not necessarily equal halves.
Sagittal plane
Planes of reference:
A special kind of sagittal plane that runs down the center of the body lengthwise and divides it into equal left and right halves. It could also be called a midsagittal plane, but that term is not commonly used.
Median plane
Planes of reference:
A plane across the body that divides it into cranial (head-end) and caudal (tail-end) parts that are not necessarily equal.
Transverse plane
Planes of reference:
A plane at right angles to the sagittal and transverse planes. It divides the body into dorsal (toward the animal’s back) and ventral (toward the belly) parts that are not necessarily equal.
Dorsal plane
In humans this is known as the frontal plane
