Question | Answer |
---|---|
Ventral | refers to the belly or underside of a body or body part. |
Cranial | means toward the head. |
Anterior | means front of the body. Used more in description of organs or body parts because front and rear are confusing terms in quadrupeds. A quadruped's belly is oriented downward, not forward as in humans. |
Rostral | means nose end of the head. |
Cephalic | means pertaining to the head. |
Dorsal | refers to the back; also refers to the cranial surface of the manus and pes. |
Manus | front paw |
Pes | rear paw |
Caudal | means toward the tail |
Posterior | means rear of the body. |
Medial | means toward the midline. |
Lateral | means away from the midline. |
Superior | means uppermost, above, or toward the head. Used more commonly in bipeds. |
Inferior | means lowermost, below, or toward the tail. Used more commonly in bipeds. |
Proximal | means nearest the midline or nearest to the beginning of a structure. |
Distal | means farthest from the midline or farthest from the beginning of a structure. |
Superficial | means near the surface; also called external |
Deep | means away from the surface; also called internal. |
Palmar | means the caudal surface of the manus (front paw) including the carpus (from the antebrachial joint distally). |
Plantar | means the caudal surface of the pes (rear paw) including the tarsus (from the tibiotarsal joint distally). |
Midsagittal plane | the plane that divides the body into equal right and left halves; it is also called the median and midline. |
Sagittal plane | the plane that divides the body into unequal right and left parts. |
Dorsal plane | the plane that divides the body into dorsal and ventral parts. It is also called the frontal plane or coronal plane. In humans, this plane is vertical because people stand erect. |
Transverse plane | the plane that divides the body into cranial and caudal parts; also called the horizontal or cross-sectional plane. It may also be used to describe a perpendicular transection to the long axis of an appendage. |
