Question

Dense regular connective tissue present in
A) Ligament and tendons
B) Joint capsule and Wharton's jelly
C) Periosteum and endosteum
D) Pericardium and heart valves

Answer 1

Hint: Dense regular connective tissue provides connection between different tissues in the human body. They have great tensile strength.

Complete Answer:
- Dense regular connective tissues are found between different tissues in the human body. They act as a connecting link between the tissues. They are divided into white and yellow fibrous connective tissue which occurs in cord and sheath arrangement. The elastic fibres are completely absent in the dense regular connective tissue. They are present in
1) Tendons-which connect muscle to bone.
2) Ligaments- bind bone to bone.

- Joint capsule, periosteum (membrane which covers the outer surface of all bones) , endosteum is made up of dense irregular connective tissue.
- Wharton's jelly is found in the umbilical cord and acts as a mucous connective tissue.
- Pericardium (membrane covering of the heart) and heart valve is made up of dense and irregular connective tissue.

Thus the correct answer is (A). Dense and regular connective tissue is present in tendons and ligaments.

Additional information: Tendons attach the muscles to the bones such as in the eyeball. It helps in movement of the bone. Ligaments attach bone to bone. It helps to hold the bones together and stable.

Note: In such an arrangement, the collagen fibres are densely packed together and arranged in parallel to each other as present in tendons and ligaments. They lack elastic fibres and provide tensile strength.
