Lesson 22; Introduction to Anatomy
How many kinds of Anatomy are there?
2 Kinds - Gross Anatomy & Microscopic Anatomy
Pathology
Deals with abnormal Anatomy & Abnormal Physiology
Midsagittal or median
Divides the body into equal right and Left sections
Sagittal or longitudinal
Divides the body into right and Left sections
transverse or horizontal plane
Divides the body into superior and inferior sections
Parasagittal
Divides the body into unequal right and left sections.
Lateral
Farther away from the midsagittal plane
You can divide the body and each organ using planes
For example a parasagittal plane of the liver divides the liver into unequal Left and right sections
Anterior and Posterior
Front and Back sections
Superior and Inferior
Top and Bottom sections
The study of tissues is called
histology
Anatomical Planes
Are established standards used to refer to the human anatomy
Medial
Closer to the midsagittal plane
Visceral
Covering of an organ
Coronal or frontal plane
Divides the body into anterior and posterior sections
gross anatomy
Includes parts of the body that can be seen with the naked eye. Also called Macroscopic Anatomy.
Physiology can be broken into 2 groups
Macroscopic physiology & Microscopic physiology
efferent
Means carrying away from a body part or the center of an organ
Afferent
Means carrying the oeard a body part or the center of an organ
Internal
Means inside or farther away from the skin or surface of an organ
External
Means outside or closer to the skin or surface of an organ
Contralateral
Means situated on or affecting the opposite side of the body
Ipsilateral
Means situated on or affecting the same side of the body
Microscopic Anatomy
Microscopic Anatomy is the science of the body's individual cells and tissues.
Dorsal
On the back side
Ventral
On the belly side
Right and Left
Patients Right and Left Sections
Morphology
Study of the form of body parts. The form of a body part includes its size, shape or color, contour and texture.
Cytology
The Microscopic study of cells.
Anatomical Position
The location of body parts is described as if the patient facing forward the palms are always facing forward thumbs face outward.
Biology
The study of the science of life and living organisms.
Caudad (caudal)
Toward the soles of the feet
Cephalad (cranial)
Toward the top of the head
Physiology is the study of how the body works
how the body functions, and it's organs, tissues and cells.
Anatomy
is the science of structure of the body-the appearance and relationships of body parts.
