Which of the following is a valid cell morphology associated with cell junctions?

• A. Spherical
• B. Columnar
• C. Cuboidal
• D. Squamous

Answer: (D)

Verified step by step guidance

1. Understand the concept of cell morphology: Cell morphology refers to the shape and structure of cells, which can vary depending on their function and location in the body. Common morphologies include squamous (flat), cuboidal (cube-shaped), and columnar (column-like).
2. Learn about cell junctions: Cell junctions are specialized structures that connect cells to each other or to the extracellular matrix. They are crucial for maintaining tissue integrity and facilitating communication between cells.
3. Relate cell morphology to cell junctions: Different cell morphologies are associated with specific types of cell junctions. For example, squamous cells, which are flat and thin, often form tight junctions to create barriers, such as in the lining of blood vessels or the skin.
4. Evaluate the options provided: Spherical cells are typically not associated with cell junctions in tissues. Columnar and cuboidal cells are valid morphologies but are not the correct answer in this context. Squamous cells are the correct answer because they are commonly associated with cell junctions in tissues like epithelial layers.
5. Conclude the reasoning: Based on the relationship between squamous cell morphology and cell junctions, the correct answer is squamous. This morphology is well-suited for forming tight barriers and facilitating junctional connections in epithelial tissues.
