Anatomy Basics Quiz

A plane that divides the body into right and left halves. Think of it like cutting an apple in half.

Any plane parallel to the median plane, slicing the body vertically but not necessarily down the middle.

A plane that cuts through the body perpendicular to the long axis, like a slice across a sausage.

A plane that divides the body into dorsal and ventral parts, like cutting a loaf of bread in half lengthwise.

Anatomical terms used to describe relative positions of body parts, like the shoulder being proximal to the hand.

A segment of the duodenum that runs vertically, starting in the 9th intercostal space and extending to the 6th lumbar vertebra. It's in close contact with the pancreas.

The right kidney in dogs is positioned between the 11th and 12th intercostal spaces. Its top part lies within the renal impression of the liver. Its location can shift based on breathing.

The liver in dogs reaches the belly button area (umbilical region) and rests on any remaining umbilical fat.

The jejunum in dogs extends from the stomach all the way to the pelvic inlet, resting on the greater omentum.

The cecum in dogs is located on the right side of the spine, between the 2nd and 4th lumbar vertebrae. Think of it as a pouch at the beginning of the large intestine.

The left kidney in horses is situated between the 17th rib and the 2nd to 3rd lumbar vertebrae. The spleen's base rests against the kidney on the side.

The stomach of a horse is relatively small and entirely within the rib cage, at about the 14th to 15th intercostal spaces.

The spleen in horses is variable in location depending on stomach content. Its outer side touches the 10th to 18th ribs. The end of the spleen is near the shoulder joint.

The jejunum is a part of the small intestine in horses, and it's located in the left dorsal quadrant of the abdominal cavity, tucked between the ribs and the pelvic inlet.

The left ventral colon is a segment of the large intestine, starting near the sternum and stretching down to the pelvic flexure. It's positioned on the left side of the horse, running from the chest towards the pelvic region.

The right kidney sits in the horse's back, just below the liver, taking up the last few intercostal spaces.

The liver, a large organ crucial for digestion, is located completely within the chest area of the abdominal cavity. It's mostly covered by the lungs, with its bottom edge reaching the 15th intercostal space.

The duodenum, the first part of the small intestine, is about a meter long and descends along the right side of the liver. It then curves to the left, near the 3rd and 4th lumbar vertebrae.

The cecum, a large pouch in the horse's digestive system, occupies a significant part of the right side of the abdomen. It stretches from the last rib area to the hip bone, with its tip located between the right and left ventral colons.

The right ventral colon, a part of the large intestine, starts near the 18th rib and runs towards the sternum. It's positioned on the right side of the horse, connecting to the cecum and then curving towards the chest.

The right dorsal colon, another part of the large intestine, starts near the 16th rib and runs up towards the 6th rib. It's positioned on the right side of the horse, connecting to the cecum and then running towards the chest.

The main artery that supplies blood to the head, neck, and forelimbs in horses.

The main artery that supplies blood to both forelimbs and neck in horses.

The main artery supplying the forelimb in horses.

The main artery supplying the head in horses.

The main artery supplying the face in horses.

The main artery supplying the brain in horses.

The main artery supplying the upper and lower jaws in horses.

The main artery supplying the hindlimb in horses.

The external jugular vein is located superficially along the neck, running parallel to the trachea and carotid artery.

The internal jugular vein runs deeper within the neck, alongside the carotid artery.

The saphenous vein is a major vein in the leg, running along the inside of the thigh.

The cephalic vein runs along the front of the forelimb, close to the surface.

The facial vein runs across the face, draining blood from the facial area.

The cranial vena cava is the main vein that carries deoxygenated blood from the head and forelimbs back to the heart.

The caudal vena cava is the main vein carrying deoxygenated blood from the hindlimbs and abdomen back to the heart.

The portal vein carries blood from the intestines to the liver for processing.

The opening in the diaphragm through which the aorta, thoracic duct, and azygos vein pass.

The opening in the diaphragm through which the esophagus, vagus nerves, and sympathetic trunks pass.

The opening in the diaphragm through which the inferior vena cava and the right phrenic nerve pass.

The area of the abdominal cavity located below the lumbar vertebrae and their transverse processes. This is the dorsal part of the abdominal cavity.

The part of the abdominal cavity formed by the soft part of the abdominal wall. It includes the paralumbar fossa.

A triangular area in the flank region, located on the dorsal part of the abdominal cavity.

The location of the testes in ruminants; low and hanging.

The location of the ovaries in ruminants; near the ventral abdominal wall, cranial to the pelvic inlet.
