metencephalon

Examples of metencephalon in the following topics:

• Development of the Central Nervous System

  • At six weeks in human embryo development, the prosencephalon divides further into the telencephalon and diencephalon and the rhombencephalon divides into the metencephalon and myelencephalon.
  • The metencephalon becomes, among other things, the pons and the cerebellum; the myelencephalon forms the medulla oblongata; and their cavities develop into the fourth ventricle.

• Parts of the Cerebellum

  • Anatomists classify the cerebellum as part of the metencephalon, which also includes the pons, and all its connections with other parts of the brain travel through the pons.
  • The metencephalon is the upper part of the rhombencephalon, or hindbrain.

• Development of the Human Brain

  • The telencephalon and diencephalon give rise to the forebrain, while the metencephalon and myelencephalon give rise to the hindbrain.

• Functions of the Brain Stem

  • The pons (part of metencephalon) lies between the medulla oblongata and the midbrain.

• Midbrain

  • Caudally (posteriorly) the mesencephalon adjoins the pons (metencephalon), and rostrally it adjoins the diencephalon (eg., thalamus, hypothalamus).

• Pons

  • During embryonic development, the metencephalon develops from the rhombencephalon and gives rise to two structures: the pons and the cerebellum.

• Embryonic Development

  • The rhombencephalon develops into the metencephalon (the pons and cerebellum) and the myelencephalon (the medulla oblongata).

• Establishing Body Axes during Development

  • The rhombencephalon develops into the metencephalon (the pons and cerebellum) and the myelencephalon (the medulla oblongata).
