Tegmentum - Wikipedia
The tegmentum (from Latin for "covering") is a general area within the brainstem. The tegmentum is the ventral part of the midbrain and the tectum is the dorsal part of the midbrain. [1] It is located between the ventricular system and distinctive basal or ventral structures at each level.

2023年10月30日 · Between the cerebral aqueduct and the pars compacta of the substantia nigra, is the larger portion of the midbrain called the tegmentum (Latin for ‘hood’). The tegmentum in the broader sense extends through the whole brainstem, …
Tegmentum | anatomy | Britannica
The tegmentum is located in front of the tectum. It consists of fibre tracts and three regions distinguished by their colour—the red nucleus, the periaqueductal gray, and the substantia nigra. The red nucleus is a large structure located centrally within the tegmentum that is involved in…

2023年5月9日 · Tectum: The posterior surface of the midbrain contains the corpora quadrigemina, which contains clusters of nerve cells called the superior and inferior colliculus. The midbrain measures around 1.5 centimeters in length and is sandwiched between the diencephalon (which includes the thalamus and hypothalamus) and the pons.
Midbrain tegmentum - Wikipedia
The tegmentum contains a collection of tracts and nuclei with movement-related, species-specific, and pain-perception functions. The general structures of midbrain tegmentum include red nucleus and the periaqueductal grey matter.

2024年9月10日 · The midbrain contains the centrally located cerebral aqueduct. Through the aqueduct, the cerebrospinal fluid (CSF) passes from the third ventricle into the fourth ventricle. In practical terms, the midbrain is distinguishable into the tegmentum, the ventral part, and the tectum, the dorsal part.

Anatomically, the midbrain comprises the tectum (or corpora quadrigemina), tegmentum, ventricular mesocoelia (or “iter”), and cerebral peduncles, as well as several nuclei and fasciculi. During embryonic development, the midbrain arises from the second vesicle, (mesencephalon) of the neural tube.
