Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of fiber has short, fine highly branched fibers?
A
collagen
B
elastin
C
reticular
D
None of the above
Explanation: 

Detailed explanation-1: -Reticular fibers are short, fine collagenous fibers that can branch extensively to forma delicate network. Collagen fibers are the strongest and most abundant of all the connective tissue fibers.

Detailed explanation-2: -Reticular fibers are highly branched, delicate, argyrophilic fibers that stain with ammoniacal silver solutions. Electron microscopic studies have shown that they are young collagen or a small bundle of collagen fibrils.

Detailed explanation-3: -A reticular fiber is the connective tissue fiber that is comprised predominantly of type III collagen. The type III collagen in reticular fiber is secreted by reticular cells. A reticular cell is a special type of fibroblast. It synthesizes collagen alpha-1 (III) for use in the production of reticular fibers.

Detailed explanation-4: -Reticular fibers are short, fine collagenous fibers that can branch extensively to form a delicate network.

Detailed explanation-5: -Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks. Its contraction is not under voluntary control.
