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.
Rigidity is the property of a structure that it does not bend or flex under an applied force. The opposite of rigidity is flexibility.In structural rigidity theory, structures are formed by collections of objects that are themselves rigid bodies, often assumed to take simple geometric forms such as straight rods (line segments), with pairs of objects connected by flexible hinges.
Allan Hobson states in his book The Reticular Formation Revisited that the name is an etymological vestige from the fallen era of the aggregate field theory in the neural sciences. The term "reticulum" means "netlike structure", which is what the reticular formation resembles at first glance. It has been described as being either too complex to ...
Deployable structures are also used on spacecraft for deploying solar panels and solar sails. Space-based deployable structures can be categorized into three primary classes: the first is the articulated structure class wherein rigid members contain sliding contact joints or are folded at hinge points and pivot to deploy, often locking into place.
An articulated locomotive with no fixed wheels (i.e. excluding the Mallet locomotive but including other articulated steam locomotives, as well as most diesel and electric locomotives) may have a separate frame beneath the superstructure, or the bodywork's internal structure may be load-bearing. Rarely is a true monocoque structure used.
Few cuts of meat feel as special as a ruby-red slice of prime rib, whether it’s served at a formal steakhouse, a Sunday afternoon buffet, or a holiday party.This well-marbled cut is flavorful ...
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 ...
