The cytoskeletal lattice of the neurohypophysial cells.
The cytoskeleton of rat neurohypophysial cells as seen in resinless sections is an irregular three-dimensional lattice of short strands of cytoplasmic matrix (the microtrabeculae) that interconnect parallel arrays of neurotubules, neurofilaments, abundant neurosecretory granules, and other membrane-bound organelles including the plasma membrane. This morphological finding suggests that the cytoplasmic ground substance constitutes a cytoskeletal continuum that may be the ultrastructural expression of a motile apparatus responsible for neurosecretory granule movement and hormone release in the neurohypophysis.
