For most of its part, the midbrain sits in the posterior cranial fossa, traversing the hiatus of the tentorium cerebelli. The midbrain is the shortest part of the brainstem. However, it contains many important ...
9 maj 2023 · The midbrain comprises two main parts: the tectum and the tegmentum. The tectum is responsible for controlling eye movements and visual reflexes, while the tegmentum controls functions such as motor coordination, posture, and pain modulation.
The midbrain is supplied by the following arteries: The tectum is supplied by the superior cerebellar artery. The central part of the tegmentum is supplied by the paramedian branches of the basilar artery. The lateral part of the midbrain is supplied by the posterior cerebral artery.
There are three main parts of the midbrain - the colliculi, the tegmentum, and the cerebral peduncles. Of the 12 cranial nerves, two thread directly from the midbrain - the oculomotor and trochlear nerves, responsible for eye and eyelid movement.
The midbrain is a part of the central nervous system, located below the cerebral cortex and at the topmost part of the brainstem. This small but important structure plays a crucial role in processing visual and auditory signals.
