Question

In which one of the following preparations are you likely to come across cell junctions most frequently?

• A. Tendon
• B. Ciliated epithelium
• C. Thrombocytes
• D. Hyaline cartilage

Answer 1

The correct option is B

Ciliated epithelium

The correct option is B.

Explanation for correct option:

• Epithelial cells are bound together in sheets of tissue referred to as epithelia. These cells are held together by several types of interactions that include tight junctions, adherens, desmosomes and gap junctions.

Explanation for incorrect options:

Option A:

1. Tendon is a tough, thick band of fibrous tissue which connects muscles to the bone.
2. Tendons are made up of collagen fibres.
3. Tendons are very strong and durable, but also flexible as they can stretch and recoil without breaking.

Option C:

1. Blood platelets are also referred to as thrombocytes.
2. Blood platelets are the tiny blood cells that form clots over the injury thus stopping the bleeding.
3. These blood cells are formed in the bone marrow and appear as very small, disc-shaped, colourless fragments but without a nucleus.

Option D:

1. Hyaline cartilage is a translucent bluish-white type of cartilage that is present in the joints, the respiratory tract, and the immature skeleton.

Final answer: In ciliated epithelium cell junctions are likely to present.
