The metencephalon is the embryonic part of the hindbrain that differentiates into the pons and the cerebellum. It contains a portion of the fourth ventricle and the trigeminal nerve (CN V), abducens nerve (CN VI), facial nerve (CN VII), and a portion of the vestibulocochlear nerve (CN VIII).

The metencephalon, the more cranial subdivision of the hindbrain, consists of two main parts: the pons, which is directly continuous with the medulla, and the cerebellum, a phylogenetically newer and ontogenetically later-appearing component of the brain (see Figure 3).

Metencephalon. The metencephalon contains the pons and cerebellum. The pons contains neurons for CN V (trigeminal), whose axons innervate the muscles of mastication. It also provides sensory innervation to the face (maxillary and ophthalmic regions) and mandible and is the location of the center for micturition.

The meaning of METENCEPHALON is the anterior segment of the developing vertebrate hindbrain or the corresponding part of the adult brain composed of the cerebellum and pons.

The Metencephalon houses many ascending and descending tracts and part of the reticular formation. These structures create a bulge, called the pons , on the brain stem's ventral surface. The pons ("bridge" in Latin) is the bridge to the cerebellum.

The metencephalon has two major components: pons and cerebellum. Pons: The pons is part of the brainstem. It contains the rostral end of the fourth ventricle and gives rise to the trigeminal nerve. The pons has distinct ventral and dorsal parts.

The metencephalon is a part of the brainstem that develops into two main structures: the pons and the cerebellum. It plays crucial roles in motor control, sensory analysis, and maintaining basic life functions.

2021年8月2日 · The metencephalon (plural: metencephala or metencephalons) is a secondary brain vesicle derived from the rhombencephalon, formed in the 5 th week of embryonic life. The metencephalon goes on to form the pons, the majority of the cerebellum and the fourth ventricle.

1. the anterior part of the rhombencephalon, comprising the pons and cerebellum. 2. the anterior of two brain vesicles formed by specialization of the rhombencephalon in the developing embryo.
