Vessels Leaving the Heart

A = brachiocephalic veinB = mammary veinC = superior vena cavaD = pulmonary veinE = external jugular veinF = subclavian veinG = subclavian arteryH = brachiocephalic arteryI = aorta

Brain-Parietal Lobe

The sheep brain shown below has the frontal and parietal lobe of the cerebrum pinned. The frontal lobe is responsible for cognitive functions such as learning and decision making. The parietal lobe is involved in how the brain processes and interprets sensory information. The cerebellum is pinned also, …

Liver and Gallbladder

The liver is a large organ located at the top of the abdominal cavity and divided into several lobes. It is only found in vertebrates and it has several functions: detoxification, protein synthesis, and production of bile and other chemicals needed for digestion. Bile produced by the liver …

Ileocecal Valve

A = mesenteryB = large intestine (ascending colon)C = ileocecal valveD = cecumE = ileum of the small intestine

Brain Stem Unlabeled

The brain stem of the sheep is located on the ventral surface of the brain. Visible features include the olfactory lobe, optic chiasma, pituitary stalk (infundibulum), midbrain, pons, medulla oblongata and the spinal cord.   The image below shows the brain of the sheep with the dura mater removed.

Radial Notch of the Ulna

The radial notch is found on the ULNA and articulates with the head of the radius to form a pivot joint.   It is located to the lateral side of the coronoid process.  The coronoid and olecranon process articulate with the humerus to form the hinge joint of the …

Cuneiform Bones of the Foot

Learning the names of the tarsals can be challenging.  If you can locate the navicular bone, which articulates with talus, then the cuneiform bones are easy to locate.  Navicular means “boat”,  so just think of the three cuniform bones as people on the boat.  The one closest to …

Male vs Female Pelvis

An illustration of a male and female pelvis showing the differences between the shape of the ileum, the angle between the right and left ischium (pubic arch).  The sacrum in females is also much wider.  These features create a larger opening in the pelvis, an adaptation for childbirth.


The placenta is connected to the umbilical cord and attaches to the wall of the uterus.  This organ allows for nutrient exchange and the removal of wastes.  The placenta develops when the blastocyst (embryo) implants into the uterine wall.  Usually this attachment occurs at the superior end of …

Dorsal and Ventral Body Cavities

Most anatomy textbooks begin with descriptions of body cavities and body regions.  These terms are important for identifying the location of structures.  For example, you will fund the lungs within the thoracic cavity, which is the region superior to the diaphragm.   The stomach and digestive organs are …
