Evolution Flashcards
The feet are flat on the floor
and close together, the arms are held downward and supinated, and
the face is directed forward. What is this describing?
Anatomical Position
In anatomical position, is the forearm supinated or pronated?
In anatomical position, the forearm is supinated—that
is, rotated so the palm faces anteriorly
How are the radius and Ulna positioned in supinated and in pronated position?
In the supinated position, the two
forearm bones (radius and ulna) are parallel and the radius
is lateral to the ulna. In the pronated position, the radius
and ulna cross; the radius is lateral to the ulna at the
elbow but medial to it at the wrist
Which anatomical plane divides the body into left and right portions?
A sagittal plane passes vertically
through the body or an organ and divides it into right and
left portions.
What is the saggital plane called that divides the body into equal halves?
The sagittal plane that divides the body or
organ into equal halves is also called the median (mid-
sagittal) plane
Which anatomical plane extends vertically and divides the body into posterior and anterior portions?
A frontal (coronal) plane also extends vertically, but it is perpendicular to the sagittal plane
Which plane divides the body into superior and inferior portions?
A transverse (horizontal) plane passes across the body or an organ perpendicular to its long axis. it divides the body or organ into superior (upper) and inferior (lower) portions
Which directional term means toward the front* or belly?
Ventral
What does the directional term dorsal mean?
Toward the back or spine
What does anterior mean?
Toward the ventral side* The sternum is anterior to the heart.
Define posterior
Towards the dorsal side
What does Cephalic mean ?
Toward the head or superior end
Which directional term means toward the forehead or nose?
Rostral
Which directional term means toward the tail or inferior end?
Caudal
