FILL IN THE BLANK WITH THE CORRECT ANATOMICAL PLANE OR DIRECTIONAL TERM.
If a horse waded into a pond until the water was about mid-chest high, the surface of the water would represent a
1) __DORSAL____________ plane through the animal’s body. After cooling off in the pond, the horse stood in the
doorway of the barn so its front, or 2) _____CRANIAL____________, end was inside the barn and its hind, or 3)
_______CAUDAL______________, end was outside. The doorway would represent a 4) ____TRANSVERSE_________ plane
through the animal’s body.
When an animal lands squarely on all four feet, the surfaces of its front feet that are on the ground are the
5) _____PALMAR___________ surfaces. The surfaces of its hind feet that are on the ground are the
6) _____PLANTAR________ surfaces. The top/front of all four feet is the 7) ________DORSAL_________ surface.
My first patient of the day was a cat that lost a piece of skin from the tip of his nose after an attack by a feisty
parrot. That wound was on the most 8) _____ROSTRAL_____________ part of the cat’s head. He was not happy when I
inserted the rectal thermometer in his 9) ____CAUDAL_____________ end. He also needed a nail trim. I always start
nail trims with the dewclaw, which is located on the inside or 10) ____MEDIAL___________ side of the paw. I then
move in the direction of the outermost nail or, 11) __LATERAL_____________ side of the paw.
I saw a cat give a cow a backrub today. The cow was lying on its ventral surface in 12) __STERNAL__________

cow’s head to tail, or in a 14) ____CRANIAL___________ to 15) _______CAUDAL________ direction. A fly landed on the
cow’s leg, just below or 16) ____DISTAL__________ to its knee.
To position dog for a ventral midline surgical incision on the abdomen, the animal’s ventral surface must face
upward. This means the animal must be in 17) ______DORSAL_______ recumbency. A ventral midline surgical
incision is centered on the 18) ______MEDIAN_______________ plane of the animal’s body. A surgical incision made 2
inches to the left of the ventral midline would be along a 19) ____SAGITTAL_________ plane. After positioning him, I
placed an IV catheter directly above, or 20) ____PROXIMAL_____ to his carpus.
