Histologically, the ________ is squamous epithelium supported by a sparse connective tissue layer.

cutaneous membrane
D
synovial membrane
Verified step by step guidance
1
Understand the question: The problem is asking about the histological structure of a specific type of membrane, which is squamous epithelium supported by sparse connective tissue.
Review the characteristics of each membrane type: Mucous membranes are typically lined with columnar or pseudostratified epithelium and are associated with mucus secretion. Serous membranes consist of simple squamous epithelium supported by a thin layer of connective tissue. Cutaneous membranes are the skin, composed of keratinized stratified squamous epithelium. Synovial membranes are specialized connective tissue that lines joint cavities and lacks epithelium.
Focus on the histological description: The question specifies squamous epithelium supported by sparse connective tissue, which matches the structure of serous membranes.
Recall the function of serous membranes: They line body cavities that do not open to the exterior and secrete serous fluid to reduce friction between organs.
Conclude that the correct answer is 'serous membrane' based on the histological description provided in the question.
