Introduction

The hindbrain consists of 3 major structures; the pons, the medulla and the cerebellum

The Hindbrain

Stick Diagram

The hindbrain consists of 3 major components;the pons (light pink, the medulla, (salmon) and the cerebellum (maroon)

The Hindbrain

The hindbrain in the sagital plane is bordered in salmon pink and consists of the pons, the medulla, and the cerebellum

Conceptual Framework of the Hindbrain

The hindbrain conceptually consists of 3 ovoids The pons is anterior and superior (light pink), the medulla is smaller and is anterior and inferior, and the cerebellum is the largest and is posterior.

The Concept In Vivo

The 3 ovoids are situated in the posterior cranial fossa the pons is anterior and superior (light pink), the medulla is smaller and is anterior and inferior, and the cerebellum is the largest and is posterior.

Advancing the Parts of the Midbrain

The shapes in fact are not quite ovoid. The pons (lightest pink) has shapes reminiscent of an oversize egg lying in a small bed The anterior eggshaped portion is called the ventral or anterior pons and the posterior portion called the tegmentum which is a continuation of the tegmentum of the midbrain. The medulla oblongata is almost rectangular but has a subtle forward bulging to its anterior surface. The anterior portion is called the ventral or anterior medulla and the posterior portion is called the tegmentum,similar in name a nad a continuation of th etegmentum of the midbrain and pons The cerebellum is situated posteriorly, is the largest of the three major components and it consists of two hemispheres and a central vermis better appreciated in the axial plane.
