Description Hypothalamus of Sphyraena obtusata (Family : Sphyraenidae) comprises
nucleus preopticus (NPO), nucleus lateralis tuberis (NLT) and their axonal
tracts. NPO is a paired structure situated on either side of the third ventricle
anterodorsal to the optic chiasma. It is a highly vascularised structure and
look inverted L-shape in sagittal section. NPO is divisible into a dorsal pars
magnocellularis (PMC) consisting of large neurosecretory cells and pars
parvocellularis (PPC) formed of smaller neurons. NLT cells are distributed
uniformly in the infundibular floor adjacent to the pituitary stalk. Neurons
of PMC and PPC contribute beaded axons to form neurohypophysial tract.
Neurosecretory colloid - like material of varying sizes are encountered in NPO.
Herring bodies are seen in the anterior as well as posterior neurohypophysis.
