Reticular fibers, reticular fibres or reticulin is a type of fiber in connective tissue [1] composed of type III collagen secreted by reticular cells. [2] They are mainly composed of reticulin protein and form a network or mesh. Reticular fibers crosslink to form a fine meshwork (reticulin).
The modulatory functions are primarily found in the rostral sector of the reticular formation and the premotor functions are localized in the neurons in more caudal regions. The reticular formation is divided into three columns: raphe nuclei (median), gigantocellular reticular nuclei (medial zone), and parvocellular reticular nuclei (lateral zone).
Descending fibers of the rubro-olivary tract project from the parvocellular red nucleus to the ipsilateral inferior olivary nucleus. [1] [3] The inferior olivary nucleus projects to the contralateral cerebellum via olivocerebellar fibers. [3] The rubro-olivary fibres descend through the superior cerebellar peduncle. [1]
Reticular connective tissue is a type of connective tissue [1] with a network of reticular fibers, made of type III collagen [2] (reticulum = net or network). Reticular fibers are not unique to reticular connective tissue, but only in this tissue type are they dominant. [3] Reticular fibers are synthesized by special fibroblasts called ...
Most input comes from collaterals of fibers passing through the thalamic reticular nucleus. The outputs from the primary thalamic reticular nucleus project to dorsal thalamic nuclei, but never to the cerebral cortex. [7] [8] This is the only thalamic nucleus that does not project to the cerebral cortex. Instead it modulates the information from ...
A reticular cell is a type of fibroblast that synthesizes collagen alpha-1(III) and uses it to produce extracellular reticular fibers.Reticular cells provide structural support, since they produce and maintain the thin networks of fibers that are a framework for most lymphoid organs.
This nucleus is known for its large number of multipolar cells and its particularly reticular structure. The reticulotegmental nucleus is topographically related to pontine nuclei (non-reticular), being just dorsal to them. The reticulotegmental nucleus has been known to mediate eye movements, otherwise known as saccadic movement. [1]
The ventrolateral geniculate nucleus has been found to be relatively large in several species such as lizards, rodents, cows, cats, and primates. [28] An initial cytoarchitectural scheme, which has been confirmed in several studies, suggests that the vLGN is divided into two parts.
