3 lis 2023 · The midbrain, or mesencephalon, is the most rostral part of the brainstem that connects the pons and cerebellum with the forebrain. For most of its part, the midbrain sits in the posterior cranial fossa, traversing the hiatus of the tentorium cerebelli .
30 wrz 2024 · Anatomically speaking, the midbrain is a complex structure with several distinct components. It’s made up of two main parts: the tectum on the dorsal (back) side and the tegmentum on the ventral (front) side. These parts work together to carry out the midbrain’s many functions.
11 paź 2024 · The midbrain (or mesencephalon), located near the very center of the brain between the interbrain and the hindbrain, is composed of a portion of the brainstem. The hindbrain (or rhombencephalon) consists of the remaining brainstem as well as our cerebellum and pons.
9 maj 2023 · The midbrain, also known as the mesencephalon, is located in the center of the brain, above the pons and below the thalamus. It is an essential part of the brainstem and connects the spinal cord to the forebrain. The midbrain consists of two main parts: the tectum and the tegmentum.
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 located between forebrain and hindbrain and is commonly segmented into tectum, aqueduct, tegmentum, and basis pedunculi. Developmentally, midbrain emerges from the second vesicle of the neural tube and does not sub-divide further, in comparison to other brain regions.
