2023年11月3日 · 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 .

The midbrain or mesencephalon is the uppermost portion of the brainstem connecting the diencephalon and cerebrum with the pons. [2] It consists of the cerebral peduncles, tegmentum, and tectum. It is functionally associated with vision, hearing, motor control, sleep and wakefulness, arousal , and temperature regulation. [3]

2024年9月10日 · During the formation of the brain itself, the neural tube induces the formation of three vesicles; the prosencephalon, the mesencephalon, and the rhombencephalon. After this stage, the three vesicles differentiate into five vesicles, with the mesencephalon becoming the midbrain and the aqueduct.

2018年3月16日 · The mesencephalon or midbrain is the portion of the brainstem that connects the hindbrain and the forebrain. A number of nerve tracts run through the midbrain that connect the cerebrum with the cerebellum and other hindbrain structures. A major function of the midbrain is to aid in movement as well as visual and auditory processing.

2023年5月26日 · The midbrain (also known as the mesencephalon) is the most superior of the three regions of the brainstem. It acts as a conduit between the forebrain above and the pons and cerebellum below. In this article, we will discuss the anatomy of the midbrain – its external anatomy, internal anatomy, and vasculature.

中脑（mesencephalon，midbrain）脊椎动物胚胎的神经管中三个扩大的中空部分的中间的一个，位于脑桥、小脑和间脑之间，并与它们相连接；其形体较小，是脑干中最短的部分，长约2cm，横越小脑幕切迹。

The midbrain, or mesencephalon, is the portion of the central nervous system that lies above the hindbrain, or rhombencephalon, and below the diencephalon, connecting the two. It is involved with sensory integration, control of motor and sleep functions and in the regulation of temperature.

It is located between the diencephalon (which includes the thalamus and hypothalamus) and the pons. On a transverse section, midbrain can be divided into three main regions: the crus cerebrum, the tegmentum (the ventral part) and the tectum (the dorsal part).

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.

2024年9月10日 · It is in the brainstem between the pons caudally (mesencephalic-pons groove) and the diencephalon, which includes the thalamus, the hypothalamus, the epithalamus, and the subthalamus. The midbrain mediates the reflexes of miosis and mydriasis and plays an essential role in sensory and motor control pathways.
