Question

White fibrous connective tissue which can withstand stretch from several directions is found in _____.

• A. Tendons.
• B. Trachea.
• C. Valves of heart.
• D. Nasal septum.

Answer 1

The correct option is A

Tendons.

The correct option is A:

Explanation of the correct option:

1. Tendons are tensile connective tissue that connects muscles to bone.
2. They are thick bundle of collagen fibres that run parallel to each other, due to the presence of collagen fibres, they are strong, flexible but inextensible.
3. The extracellular matrix and connective tissue cells make up the extracellular matrix in tendons.
4. Tenocytes are specialized fibroblasts that are located in the tendon. Tenocytes secrete collagen fibres that make up the tissue's extracellular matrix.
5. Tendons primary function is to form a connection between muscle and bone, which aids in bone mobility and offers additional support.
   

Explanation of the incorrect options:

Option B:

1. The trachea, often known as the windpipe, is a cartilaginous tube that connects the mouth and larynx to the lungs, allowing air to travel through.
2. It is found in almost all animals with lungs.
3. From the larynx, the trachea branches into the two major bronchi.

Option C:

1. The four valves of the heart keep blood flowing in the right direction.
2. The mitral valve, tricuspid valve, pulmonary valve, and aortic valve are all examples of these valves.
3. Flaps (leaflets or cusps) on each valve open and close once per heartbeat.

Option D:

1. The nasal septum is a layer that separates the nostrils in the nasal cavity.
2. It starts at the nares, or anterior nasal apertures, and terminates at the choanae, or posterior nasal apertures, at the juncture of the nasal cavity and the nasopharynx.

Final answer: White fibrous connective tissue which can withstand stretch from several directions is found in tendons.
