	Gray, Henry. 1918. Anatomy of the Human Body. Page 738
		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.
		The cerebellum is developed by a thickening of the roof, and the pons by a thickening in the floor and lateral walls of the metencephalon.
		The floor and lateral walls of the myelencephalon are thickened to form the medulla oblongata; its roof remains thin, and, retaining to

	Myelencephalon (Site not responding. Last check: 2007-10-18)
		The Myelencephalon (or medulla) is the posterior portion of the brain stem.
		An interesting part of the myelencephalon from a psychological perspective is the reticular formation.
		It is a complex network of about 100 tiny nuclei that occupies the central core of the brain stem from the posterior boundary of the myelencephalon to the anterior boundary of the midbrain.

		The myelencephalon, or medulla oblongata, is one of the last portions of the brainstem to be contained in the cranium.
		The myelencephalon is a developmental categorization of a portion of the central nervous system.
		The myelencephalon is composed of the medulla oblongata; contains a portion of the fourth ventricle; as well as the glossopharyngeal nerve (CN IX), vagus nerve (CN X), accessory nerve (CN XI), hypoglossal nerve (CN XII), and a portion of the vestibulocochlear nerve (CN VIII).

	The Brain
		The terms telencephalon, diencephalon, mesencephalon, metencephalon, and myelencephalon denote five distinct embryonic subdivisions.
		The paired cerebral hemispheres are mirror-image duplicates composed of a gray cellular mantle called the cerebral cortex, an underlying mass of white matter composed of myelinated nerve fibers, and collections of subcortical neuronal masses known as the basal ganglia.
		The hindbrain consists of the pons (or metencephalon) and the medulla oblongata (or myelencephalon).

	Chapter Summary
		I. During embryonic development, five regions of the brain are formed: the telencephalon, diencephalon, mesencephalon, metencephalon, and myelencephalon.
		A. The telencephalon and diencephalon constitute the forebrain; the mesencephalon is the midbrain, and the hindbrain is composed of the metencephalon and the myelencephalon
		B. The CNS begins as a hollow tube, and thus the brain and spinal cord are hollow.

	Development of the Brain
		• The roof plate of the myelencephalon consists of a single layer of ependymal cells which is later covered by vascular mesenchyme, the pia mater.
		• The basal motor plate of the myelencephalon contains the motor nuclei which are divided into three groups.
		This forms the continuation of the anterior horn cells of the cervical cord, and these motor neurons innervate striated muscle.
