Your brainstem connects your brain to your cervical spinal cord (neck) and consists of three main parts: Midbrain. Pons. Medulla oblongata. (Sometimes, the diencephalon is also considered part of the brainstem.)

3 lis 2023 · The midbrain consists of two major parts: cerebral peduncles and tectum. The cerebral peduncles consist of the crura cerebri and tegmentum. They are separated from each other by a darkened stripe called the substantia nigra.
9 maj 2023 · The midbrain is divided into two distinct portions: the anterior midbrain and the posterior midbrain. The anterior midbrain comprises the cerebral peduncles, which are bundles of nerve fibers connecting the midbrain to the cerebrum.
The midbrain is the uppermost part of the brainstem. Its substantia nigra is closely associated with motor system pathways of the basal ganglia. The human midbrain is archipallian in origin, meaning that its general architecture is shared with the most ancient of vertebrates.
midbrain, region of the developing vertebrate brain that is composed of the tectum and tegmentum. The midbrain serves important functions in motor movement, particularly movements of the eye, and in auditory and visual processing.
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.
