Question

Epimysium of muscles is made up of
(a)White fibrous connective tissue
(b)Adipose connective tissue
(c)Reticular connective tissue
(d)Areolar connective tissue

Answer 1

Hint: The epimysium is a sheath of fibrous elastic tissue surrounding a muscle. The most significant biological function of this layer is protection from strain and friction that is caused by the movement of muscles.

Complete answer:
Epimysium is the outermost white fibrous connective tissue that completely encloses the skeletal muscle of the body. White fibrous connective tissue is dense regular connective tissues that are physically tough, yet pliable and silvery-white color appearance. It has fibroblasts which is interspersed among the many collagen fibers. The collagen fibers are aligned in the same direction and provide a mechanically strong structure. White fibrous tissues are mainly present in skins, tendons, ligaments, bone, and cartilage. Some examples of white fibrous tissues are-
-The sclera of the eye is formed of white fibrous tissue intermixed with fine elastic fibers; flattened connective-tissue corpuscles.
-Modified synovial structures, is a small fluid-filled sac formed from white fibrous tissue which is lined with synovial membranes.

Additional Information:
-The Epimysium of muscle is made up of dense irregular connective tissue.
-The epimysium typically encompasses many bundles (fascicles) of muscle fibers.
-The smoothness of these tissues encourages seamless gliding and promotes the smooth movement of the limbs and joints.
-It also protects joints and other high-impact areas from rips or tears.
So the correct answer is “White fibrous connective tissue”.

Note: The perimysium is the loose connective tissue that surrounds each bundle of muscle fibers. The endomysium is a fine and delicate layer of areolar connective tissue that encases each muscle fiber. It also contains capillaries, nerves, and lymphatics. The epimysium, perimysium, and endomysium together allow autonomous gliding of muscle fibers during muscle contraction. The perimysium and endomysium also regulate the metabolic exchange between muscle and blood.
