Gray matter: Some cranial nerve nuclei and nuclei of pontine part reticular formation. l Abducent nerve nucleus: It is the nucleus of somatic efferent.
Structural characteristics Stretching of roof plate at this plane of medulla oblongata in embryonic life causes outward deviation (abduction) of alar.
Structural characteristics There is no more existance of gray matter area which is homologous to anterior horn. Gray matter of posterior horn presenting.
Structural characteristics At this level structure of medulla oblongata is almost similar to the structure of spinal cord, with centrally positioned gray.
Central cavity of brainstem show different characteristics and names at different level. At lower end of medulla it is a narrow canal continuous below.
Brainstem is the tubular stalk-like part of the brain made up of midbrain, pons and medulla oblongata from above downward. It is so called because it is.
Floor of fourth ventricle is formed by dorsal surfaces of pons and upper-half of medulla oblongata. It is called rhomboid fossa because it is rhomboid.
A nerve fiber, either in peripheral or in central nervous system carries nerve impulse towards destination. This impulse must reach the destination to.
