- - Probably we should start by defining the brainstem. It consists of all the brain caudal to the forebrain. Practically, however, the thalamus (part of the forebrain) is so closely related to the brainstem that we are going to include it in our discussion. In most of our drawings in this module we will follow the color code shown in this view. Namely:

Thalamus ____________ pea green

Midbrain ____________ light blue

Pons and Cerebellum ___ pink

Medulla _____________ yellow

- - The brain is, from an embryological point of view, the rostral end of the neural tube - continuous caudally with the spinal cord in the region of the foramen magnum. Unlike the spinal cord, in which each segment looks more or less like the next one, regional differences in development give each division of the brainstem its own peculiar appearance.
