Document Summary
Brain stem lies at the inferior surface of the brain. Midbrain is the most superior structure; it"s separated by a space, dividing central and posterior. Cerebellum lies posterior to the brain stem, and inferior of cerebral cortex. Cerebellum is separated from brain stem by this diamond-like structure (4th ventricle: filled with midbrain. Csf) (3rd ventricle is just underneath the thalamus); 3rd ventricle will flow csf into cerebral aqueduct, and into the 4th ventricle. Cerebral aqueduct is the continuation of the 4th ventricle; it connects the 3rd and 4th ventricles. So can see the cerebral aqueduct at the midbrain. The main ventral surfaces that you"ll see in the midbrain is the cerebral peduncles (greek for. Axon fibres traveling down to the motor cortex to the spinal cord (that"s why it looks like rods - Surface of the pons: instead of up / down fibre shape, it"s left and right; that"s because fibres are.
