Hindbrain is made up by these three parts of brain- Cerebellum Pons Medulla Oblangata

Cerebral peduncles are two broad bundles situated at the lower part of the midbrain and appear on the ventral face of the brain as two columns that emerge from under the pons and diverge forward to enter the cerebrum. At the point of disappearance, the optic tract winds obliquely across the peduncle. These contain the

The cerebral aqueduct or aqueduct of Sylvius is a narrow passage through the mesencephalon and connects the third and fourth ventricles. It is situated at the median plane. The shape of the lumen is variable at different places. It is lined by ciliated columnar epithelium. Surrounding it is a layer of gray mater which is

Corpora Quadrigemina are four rounded eminences, which form the upper part of the midbrain and lie under posterior part of the cerebral hemispheres. They consist of two parts of colliculi (anterior and posterior)separated by a transverse groove. The anterior colliculi are larger and placed higher in level than the posterior and are known as nates.

The basal ganglia consists of masses of gray mater or nuclei, viz. the caudate and lenticular nuclei, claustrum and amygdaloid within the cerebral hemisphere. The caudate and lenticular nuclei are incompletely separated by tracts of white mater called the internal capsule . The internal capsule actually consists of a masses of projection fibres connecting cerebral

Fornix of Brain is composed of longitudinal white fibers that arch over the thalamus and the third ventricle. It consists of a body and two pairs of pillars, anterior and posterior. The body is formed by the fusion of the two arches by which the fornix is composed. It is triangular and overlies the anterior part of

Pineal gland  Pineal body is a small ovoid or fusiform gland situated dorsally in a deep depression between the thalami and the corpora quadrigemina. It is attached to the postero-superior quadrant of the third ventricle by a hollow stalk, which is a small recess of the third ventricle. Immediately under the posterior part of the

Interbrain-thalamus is a large ovoid mass of gray mater situated obliquely across the dorsal face of cerebral peduncles, so that the two bodies meet in front at a right angle.  Medially they are fused to large extent and around this area of adhesion is an annular space called the third ventricle. The dorsal face of

Olfactory bulbs Rhinencephalon or Olfactory bulbs are oval elongated structures in each hemisphere, situated at the anteroventral aspect of the frontal pole and are lodged in the olfactory fossae Each bulb receives olfactory nerves coming from the nasal mucosa through the olfactory perforations of the cribriform plate of the ethmoid bone. The olfactory tract is
