Examples

  • It is customary to divide the rest of the hind-brain into two parts, viz., an upper, called the metencephalon, and a lower, the myelencephalon.

    IX. Neurology. 2. Development of the Nervous System

  • On transverse section the myelencephalon at an early stage is seen to consist of two lateral walls, connected across the middle line by floor - and roof-plates (Figs. 647 and 648).

    IX. Neurology. 2. Development of the Nervous System

  • The floor and lateral walls of the myelencephalon are thickened to form the medulla oblongata; its roof remains thin, and, retaining to a great extent its epithelial nature, is expanded in a lateral direction.

    IX. Neurology. 2. Development of the Nervous System

  • Developmentally considered, the fourth ventricle consists of three parts: a superior belonging to the isthmus rhombencephali, an intermediate, to the metencephalon, and an inferior, to the myelencephalon.

    IX. Neurology. 4a. The Hind-brain or Rhombencephalon

  • It consists of (a) the myelencephalon, comprising the medulla oblongata and the lower part of the fourth ventricle; (b) the metencephalon, consisting of the pons, cerebellum, and the intermediate part of the fourth ventricle; and (c) the isthmus rhombencephali, a constricted portion immediately adjoining the mid-brain and including the superior peduncles of the cerebellum, the anterior medullary velum, and the upper part of the fourth ventricle.
