A is an early stage, dorsal aspect, B the brain of a three-weeks embryo in lateral aspect, C that of an eight-week embryo in lateral aspect. 449.-Three stages-A, B, and C-in the development of the human brain, showing the brain vesicles and flexures. OLFACTORY LOBE PONTINE FLEXURE CERVICAL FLEXURE SPINAL CORD A. The caudal part of the midbrain and the rostral part of the hindbrain makes up a mibrain-hindbrain boundary region known as the isthmic organizer. The mesencephalon, which gives rise to oculomotor (III) and trochlear (IV) cranial nerves, contains the mesencephalic aqueduct. In transverse sections of the eel the large cells of the praeopticus nidulus which lie between the optic tracts give off large, deeply stained, unmeduUated fibres which pursue a lateral course with those of the ependyma toward the lateral walls, i.

The cephalic flexure, also known as the mesencephalic flexure, is the first flexure or bend, that forms in the region of midbrain. These cells also resemble those of the mesencephalic root of the fifth and the cells of origin of Mauthners fibres. This image could have imperfections as it’s either historical or reportage.
