Dissection of the meninges and brain in situ. On the right the calvaria and layers of the scalp are shown in relation to the dura. On the left the dura has been cut away to reveal the cerebral hemisphere and cerebellum covered with the arachnoid membrane. The confluence of the sinuses is shown.

The sclera and cornea have been cut away on the medial side of a right eye to display the anterior chamber, iris, ciliary body and outer surface of the choroid. Although none of the vessels has been injected, the branches of the superior and inferior medial vorticose veins are clearly visible. The long posterior ciliary artery was cut across in the resection of the sclera but its course can be traced nearly to the ciliary body.

On this dissection of the heart, the epicardium has been removed from all parts of the atria with the exception of the left auricle.

Dissection of lungs in situ. The lungs have been dissected from their medial surfaces and are reflected laterally for this image. Fragmentary portions of all of the chambers of the heart have been preserved. The great vessels have been kept intact, although the aorta and pulmonary trunk have been elevated to expose more posterior parts of the heart.

The cervical spinal cord. By removing the rear arches of the neck (cervical) vertebra and the fibrous covering (dura) over the spinal cord one sees the cervical spinal cord and its nerves. The blood vessels nourishing the cord and vertebral column and the origin of the cord from the brain are clearly shown.

Dissection of thorax from a posterior approach. Ribs and vertebral bodies have been resected bilaterally between the second and the ninth thoracic segments. The periosteum which covered the inner surfaces of the ribs have been preserved in most areas. The anterior longitudinal ligament, with remnants of the intervertebral discs attached, has also been retained in part. The lungs have been inflated and are visible through the intact costal pleura. The proximal parts of the III-VII spinal nerves have been positioned on the pleura in such a way that their dorsal and ventral roots, dorsal rami and communications with the sympathetic trunks are visible. These components are labeled for the left seventh thoracic nerve. The intercostal arteries and veins have been cut off in various ways.
