Simple receptors that are particularly abundant in epithelia and connective tissue tend to __________.

• A. have nonencapsulated (free) nerve endings
• B. be sense organs
• C. only have encapsulated nerve endings
• D. be mechanoreceptors

Answer: (A)

Verified step by step guidance

1. Understand the types of receptors: In anatomy, receptors are specialized structures that respond to specific stimuli. They can be classified based on their structure and function.
2. Identify the location of simple receptors: Simple receptors are commonly found in epithelia and connective tissues. These tissues are widespread throughout the body, providing a protective layer and structural support.
3. Differentiate between encapsulated and nonencapsulated nerve endings: Encapsulated nerve endings are surrounded by a capsule that enhances their sensitivity to specific stimuli, while nonencapsulated (free) nerve endings lack such a capsule and are more common in simple receptors.
4. Consider the function of mechanoreceptors: Mechanoreceptors are a type of receptor that responds to mechanical pressure or distortion. They can be either encapsulated or nonencapsulated, depending on their specific role and location.
5. Conclude the characteristics of simple receptors: Given their abundance in epithelia and connective tissues, simple receptors are likely to have nonencapsulated (free) nerve endings, allowing them to detect a variety of stimuli without the need for specialized structures.
