Choose the correctly matched pair.
A) Tendon – Specialized connective tissue
B) Adipose tissue – Dense connective tissue
C) Areolar tissue – Loose connective tissue
D) Cartilage – Loose connective tissue
Solution
Connective tissues, as the name implies, support and connect different tissues and organs of the body. They are generally distributed in every part of the body. They originate from the mesoderm (the middle germinal layer of the embryo). These tissues are made up of a few cells present in the intercellular framework of protein fibres produced by the cells, called collagen or elastin. The cells
also make/secrete a thin gel of polysaccharides, which together with fibres make matrix/ground
substance.
Complete answer: Areolar Tissue: Present under the skin and supports the epithelium. It possesses randomly distributed fibres, fibroblasts, mast cells, and macrophages. It makes a support system in the organs present in the abdominal cavity, fills the space between muscle fibres, and wraps around blood and lymph vessels.
Adipose Tissue: They are present under the skin and they usually store fat. It acts as a shock absorber
and helps in maintaining body temperature in colder environments. They are also loose connective
tissue. White adipose tissues protect kidneys and are also found at the back of the eye, in the hump of
camels, blubber of whales, etc.
Tendon ligaments are dense connective tissue.
Hence, the correct answer is Option C
Note: Loose connective tissues are present all over the body, where support and elasticity both are needed. Blood vessels, nerves, and muscles, all possess a loose connective tissue wrapping. They form the subcutaneous layer (under the skin layer) along with adipose tissues, attaching muscles, and other various structures to the skin. The fibres and cells are loosely organized in the semi-fluid matrix. They are found between many organs as a filling and like a shock absorber and reservoir for salt and fluid.
