interfascicular

No differentiation between fascicular and interfascicular regions of the secondary xylem is apparent, and ray cells are rarely observed.

There was not a significant difference between the results of fascicular and eipneural, but a significant difference between the two and interfascicular.

The epineurium separates the nerve fascicles, but lies outside the perineurium (i.e. interfascicular epineurium).

The anterior tibial nerves of dogs were cut to determine which of fascicular, interfascicular and epineural suture techniques were best.

The rostral aspect of the dorsal raphe is further divided into interfascicular, ventral, ventrolateral and dorsal subnuclei.

The fascicular and interfascicular cambiums, therefore, represent a continuous ring which bisects the primary xylem and primary phloem.

Schwann cells supply the myelin for peripheral neurons, whereas oligodendrocytes, specifically of the interfascicular type, myelinate the axons of the central nervous system.

Some definitions of the VTA also include the midline nuclei (i.e. the interfascicular nucleus, rostral linear nucleus, and central linear nucleus).

Upon maturity, this region is known as the fascicular cambium, and the area of cells between the vascular bundles (fascicles) called pith rays becomes what is called the interfascicular cambium.

By the formation of a layer of cambium between the bundles (interfascicular cambium), a complete ring is formed, and a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside.

Input regions include septal nuclei (the nucleus fimbrialis septi and the nucleus triangularis septi), dopaminergic inputs from the interfascicular nucleus of the ventral tegmental area, noradrenergic inputs from the locus ceruleus, and GABAergic inputs from the diagonal band of Broca.
