Question

Areolar connective tissue joins
A) Fat body with muscles
B) Integument with muscles
C) Bones with muscles
D) Bones with bones

Answer 1

Loose connective tissue (LCT), also known as areolar tissue, belongs to the group of proper connective tissue. Its cellular content is very abundant and varied. The ECM consists of a moderate amount of ground material and two main forms of protein fibres: elastic and reticular.

Complete Answer:
Option (a) is incorrect because the adipose tissue connects the fat body with the muscles.
Option (c) is incorrect because bones are connected to the muscles by tendons
Option (d) is incorrect as the bones are attached to bones by ligaments.
Option (b) is correct as the Integuments are connected with muscles by areolar connective tissue.
- Areolar tissue is located below the dermis layer and is also below the epithelial tissue in all body systems with external openings.
- It is also a part of the lamina propria of the digestive and respiratory tract, the mucous membranes of the reproductive and urinary system, the stroma of the glands and the hypodermis of the skin.
- It is also present in the mesentery that surrounds the intestine. Due to its venue, LCT is a significant site of inflammatory and immune reactions.
- This is where possible pathogens that have broken the skin are confronted and hopefully killed by the immune system. LCT is also well-vascularized to allow successful movement of immune cells.

Note: Areolar connective tissue consists of cells and an extracellular matrix ("extra-" means "outside," so that the extracellular matrix is a substance outside the cells). The matrix has two elements, the fibre and the ground material.The only part of the cells that can be seen is the nucleus. The material of the earth has no structure, so you can't assume it's there. The ground material occupies all the gaps between the cells and the fibres.
