The lamina propria of the mucosa is composed of which type of tissue?

• A. Loose connective tissue
• B. Stratified squamous epithelium
• C. Dense regular connective tissue
• D. Smooth muscle tissue

Answer: (A)

Verified step by step guidance

1. Understand the structure of the mucosa: The mucosa is a layer of tissue found lining various organs, such as the gastrointestinal tract. It consists of three main components: the epithelium, the lamina propria, and the muscularis mucosae.
2. Define the lamina propria: The lamina propria is the connective tissue layer of the mucosa. It provides support to the epithelium and contains blood vessels, lymphatic vessels, and immune cells.
3. Identify the type of tissue in the lamina propria: The lamina propria is composed of loose connective tissue, which is characterized by a loose arrangement of fibers and cells. This tissue type allows for flexibility and provides space for blood vessels and immune cells.
4. Compare the options provided: Loose connective tissue is the correct answer because it matches the description of the lamina propria. Stratified squamous epithelium is part of the epithelial layer, dense regular connective tissue is found in tendons and ligaments, and smooth muscle tissue is part of the muscularis mucosae.
5. Conclude the reasoning: Based on the structure and function of the lamina propria, the correct answer is 'Loose connective tissue,' as it aligns with the anatomical and physiological characteristics of this layer.
