Preferred Label : myelencephalon;
Uberon definition : The posterior part of the developing vertebrate hindbrain or the corresponding part
of the adult brain composed of the medulla oblongata and 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).[BTO,WP].;
Uberon related term : myelencephalon (medulla oblongata);
Uberon Homology note : The early development of most vertebrate brains is similar (...). The zebrafish neural
tube follows the same basic differentiation pattern as the mammalian neural tube (reference
1); The brain develops from three embryonic enlargements of the neural tube, which
later differentiate into five regions. A forebrain differentiates into telencephalon
and diencephalon. The midbrain, or mesencephalon, remains undivided. The hindbrain
divides into the metencephalon and myelencephalon. Cavities within the brain enlarge
to form a series of interconnected ventricles (reference 2).[well established][VHOG];
Uberon Terminology note : the terms metencephalon and myelencephalon are only meaningful in mammals and birds
- Neuroanatomy of the Zebrafish Brain. Note that its not clear if this refers to the
developing medulla oblongata - MA (adult) has two distinct classes;
