Carefully remove the fronto-parietals so as to expose the brain, and note the following parts:—
(a) The olfactory lobes, forming the most anterior portion of the brain, united together in the middle line. Anteriorly the olfactory nerves are given off.
(b) The cerebral hemispheres, a pair of smooth elongated bodies.
(c) The thalamencephalon, lying immediately behind the cerebral hemispheres. It is covered by the choroid plexus, a thick vascular membrane, and gives rise dorsally to the stalk of the pineal body.
(d) The optic lobes, a pair of oval bodies.
