Why do we use Anatomic Reference Systems? What are they? | We use them to describe structural units of the body. The reference systems include Body Cavities, Body Planes, Body Directions & Structural Units. |
What are body planes? Name them. | Body Planes are imaginary vertical & horizontal lines used to divide the body into sections for descriptive purposes. They are SAGGITAL, MID SAGGITAL & TRANSVERSE. |
What body position is considered "anatomically correct"? | Standing straight with the body standing tall & facing forward, with arms down to the side and palms facing outward toward the front of the body. |
Name & describe the 2 main Body Direction terms. | Ventral- The front or belly side of the body Dorsal- The Back side of the body |
Describe the Vertical Body Planes. | Saggital/ Divides the body into equal left & right parts Midsaggital/ Divides the body into unequal left & right parts Frontal/ Divides the body into anterior (front) & dorsal (back) parts. Also known as "coronal" |
Describe the Horizontal Body Planes. | Transverse/ Divides the body into equal top & bottom parts. Can be at the waist or any other level across the body |
Name & describe secondary Body Terms | Cephalic- Toward the head Caudal- Toward the feet Anterior (ventral)- Toward the back Posterior (dorsal)- Toward the front |
