Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
On the electron photomicrograph there is a cell of loose fibrous connective tissue, that takes part in the immune reactions. This cell contains eccentric nucleus, a prominent clear area in the cytoplasm that is adjacent to the nucleus, and well developed granular endoplasmic reticulum. What cell is it:
A
mast cell
B
plasmocyte
C
macrophage
D

E
fibroblast
Explanation: 

Detailed explanation-1: -Loose connective tissue is composed of loosely woven collagen and elastic fibers. The fibers and other components of the connective tissue matrix are secreted by fibroblasts.

Detailed explanation-2: -Areolar tissue It is strong enough to bind different tissue types together, yet soft enough to provide flexibility and cushioning. It exhibits interlacing, loosely organized fibers, abundant blood vessels, and significant empty space filled with interstitial fluid.

Detailed explanation-3: -The outermost layer, which attaches the vessel to the surrounding tissue, is the tunica externa or tunica adventitia. This layer is connective tissue with varying amounts of elastic and collagenous fibers.

Detailed explanation-4: -Slide 72 Tendon. Fibroblasts are the most common cell type of connective tissue. They produce both fibers and amorphous ground substance.
