Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of tissue has a delicate network of woven fibers and is found in lymph nodes, the spleen and bone marrow?
A
dense fibrous
B
adipose
C
reticular
D
elastic cartilage
Explanation: 

Detailed explanation-1: -Reticular tissue, a type of loose connective tissue in which reticular fibers are the most prominent fibrous component, forms the supporting framework of the lymphoid organs (lymph nodes, spleen, tonsils), bone marrow and liver.

Detailed explanation-2: -Reticular Connective Tissue. Reticular fibers (type III collagen) form a delicate network on which cells (the predominant element) are suspended. Reticular cells attach to and cover the fibers with their long, thin processes.

Detailed explanation-3: -Reticular tissue is a special type of connective tissue that predominates in various locations that have a high cellular content. It has a branched and mesh-like pattern, often called reticulum, due to the arrangement of reticular fibers (reticulin). These fibers are actually type III collagen fibrils.

Detailed explanation-4: -In the spleen, reticular fibers provide a supporting framework for the capsule, C; for the trabeculae, T, which contain the larger blood vessels; and for the central arterioles, A. A fine reticular meshwork is present throughout the organ in the red pulp.
