With all layers of the skin removed on the left side of the head and neck, the dissection displays the blood vessels and nerves of the scalp, almost all of which come from the periphery, not through the skull. Colored latex was injected into the blood vessels: red for arteries, blue for veins. The structures in the neck remain covered by a tough layer of tissue known as the cervical fascia.

Inside the vertebral column, cut in half vertically, is a channel for the spinal nerves. The brown material is the bones; the white material is the intervertral disks that sometimes "rupture," causing back pain. A horizontal split has been made on the left to show the connection of the sacrum, a triangular bone at the base of the spine, to the pelvis.

This view of the wrist joint features the two rows of four carpal bones each and shows how they are connected to the bones of the forearm and the fingers.

A dissection of the leg and the foot displays the long tendons connected to the toes, and the blood vessels and nerves to the top of the foot.

This dissection of the backbone was performed by Donald Stilwell, another Stanford professor, for the Bassett atlas. Note the profusion of arterial blood vessels nourishing the vertebral area of the neck and chest area. Also, at the top, the ends of the vertebral arteries, which pass into the skull to nourish the brain.

The mediastinum, a central chest compartment located between the lungs, houses the heart. Immediately to the right of the heart is the aorta, the largest artery of the body. To the right of the aorta are groups of blood vessels (one artery and two companion veins) that run between the ribs to distribute blood through the body. The phrenic nerve, which sends messages to the diaphragm to breath, is visible as it crosses the heart vertically.
