Human Body (Directional Terms & Body Planes) Flashcards
- Large structures
* Easily observable
Gross anatomy
- Structures are too small to be seen with the naked eye
* Cells and tissues can be viewed only with a microscope
Microscopic anatomy
• study of the human body’s structure and their relationship to one another
ANATOMY
• study the function of the body’s structural machinery / how all the body parts work and carry out their life-sustaining activities
PHYSIOLOGY
• Divides the body into RIGHT & LEFT portion
Sagittal Plane
2 Plane in Sagittal Plane
Midsagittal Plane
Parasagittal Plane
(Cross-Sectional Plane)
Transverse Plane
(Frontal Plane)
Coronal Plane
• Divides the body into upper (superior) & lower (inferior) portion
Transverse Plane
• divides the body into FRONT (Anterior) & BACK (Posterior) portion
Coronal Plane
• Explain location of one body structure in relation to another

Posterior
toward or at the midline of the body; on the inner side of
Medial
away from the midline of the body; on the outer side of
Lateral
between a more medial and a more lateral structure
Intermediate
- close to the origin of the body part
- Closer to the torso
- Nearest point to structure
Proximal
- farther from the origin of a body part
- Parts and places away from the torso
- Farthest way from origin
Distal
Proximal and Distal is used for UPPER and LOWER __
EXTREMITIES
sections are cuts along imaginary lines
