Question

Areolar tissue joins
A. Integument with muscles
B. Bones with muscles
C. Bone with bone
D. Fat body with muscles

Answer 1

Hint: Areolar tissue is a loose connective tissue that comprises many varieties of fibres that are poorly organised. It fills the space between different organs to maintain a position, and cover the blood vessels and sustain them.

Complete Answer:
Areolar tissue is found beneath the skin as subcutaneous tissue in the submucosa of the gastrointestinal and respiratory tract, in the bone marrow, between the lobes and lobules of the compound glands, between and around the muscles, nerves and blood vessels. There is a rich source of nerve fibres for Areolar connective tissue. The primary function of areolar connective tissue is the attachment of body parts together. Integument in plants or animals means an outer layer. The skin is an outer layer for any organism. So Areolar tissue binds the muscles of the skin/integument.

Option B is incorrect since bones are attached by tendons to muscles. A tendon is a tough band of connective fibrous tissue that connects bone to muscle. Tendons link the bone to the muscle.

Option C is wrong since the connective tissues connecting the bones with the bones are ligaments. Blocks of tough elastic tissue around the joints are ligaments. They connect bone to bone, provide support to the joints, and restrict their movement.

Option D is incorrect since fat bodies are related by adipose tissues to muscles. Adipose tissue is a specialised connective tissue which consists of adipocytes called lipid-rich cells.

So, the correct option is A, Integument with muscles.

Note: Tissues that attach, sustain, anchor, or detach various tissues or organs within the body are connective tissues (CT). Fibrous, adipose, cartilage, bone, blood, and reticular and areolar tissues are the six primary categories of connective tissues.
