Anatomical Terms
First flashcard set of Anatomy and Physiology Honors
Term | Definition |
---|---|
They precisely describe the location of features. | Why do we use anatomical terms? |
Anatomical Position | standard position in which structures are described; standing upright, arms at the sides, palms forward, feet together |
Left and right | refers to the sides of the person in the anatomical position (not you as the observer) {so opposite of you} |
Anterior (ventral) | front of the body |
Posterior (dorsal) | back of the body |
Superior (cranial) | above or closer to the head |
Inferior (caudal) | below or closer to the feet |
Proximal | closer to the point of attachment |
Distal | away from the point of attachment |
when describing 2 points on the same limb (arm or leg) | Distal and Proximal are only used... |
Medial | closer to the midline |
Lateral | farther away from the midline |
Directional Terms | describes position of external structures |
Planes or sections | used to help us observe the internal structures of the body |
Sagittal, Frontal, Transverse, and Oblique | 4 anatomical planes |
Sagittal Plane | lengthwise cut that divides the the body into left and right |
Mid-Sagittal Plane | if cut is through the midline |
Para-sagittal Plane | if cut is not through midline |
Frontal (coronal) Plane | sideways cut, divides body into anterior and posterior portions |
Transverse Plane | horizontal cut, divides body into superior and inferior portions |
Oblique Planes | slanting or sloping; not straightforward or direct angles |
Axial Parts | everything that is in line with the head, neck, and body/trunk |
Appendicular parts | arms and legs or appendages |
