Question | Answer |
Anatomy | Study of Structure; Greek for "to cut up" or "cut open" |
2 Categories of Anatomy | Microscopic Anatomy and Gross Anatomy |
Structural Organization of the Human Body | Chemical Level (Atoms/Molecules); Cellular Level; Tissue Level4; Organ Level; Organ System Level (11 Organ Systems); Organism Level |
Organ Systems | Comprised of organs that work together to perform specific functions; 11 organ systems in the human body |
Anatomic Position | Standing; Feet parallel and on the floor; Head level and looking forward; Arms at side of body; Palms facing forward and thumbs pointing away from body |
"Section" Anatomic View | An actual cut or slice through a structure |
"Plane" Anatomic View | An imaginary flat surface passing through the body or an organ |
Anatomic Planes | Coronal Plane, Transverse Plane, Sagittal Plane; Midsagittal; Oblique |
Coronal Plane | Divides the body into anterior (front) and posterior (back) parts |
Transverse Plane | Divides the body into superior (upper) and inferior (lower) parts |
Sagittal Plane | Divides the body into left and right parts |
Mid-Sagittal Plane | Divides the body into EQUAL left and right halves |
Oblique | Transverse view from an angle |
Purpose of Anatomic Direction | Allow us to describle the relative position of one body structure in relation to another |
Anatomic Directions | Anterior (ventral) vs posterior (dorsal); Superior (cranial) vs Inferior (caudal); Medial vs Lateral; Proximal vs Distal (relates to origin of structure); Internal vs external; Deep vs superficial |
Anatomic Regions | Axial (head, neck and trunk - the vertical axis of the body); Appendicular (upper and lower limbs - appendages) |
