Epithelial tissues have ______ innervation.

• A. no
• B. poor
• C. variable
• D. good

Answer: (D)

Verified step by step guidance

1. Understand the term 'innervation': Innervation refers to the supply of nerves to a specific tissue or organ, allowing it to communicate with the nervous system.
2. Recall the characteristics of epithelial tissues: Epithelial tissues are specialized for covering surfaces, lining cavities, and forming glands. They are highly functional and require communication with the nervous system for sensory and regulatory purposes.
3. Consider the relationship between epithelial tissues and the nervous system: Epithelial tissues are known to have a rich supply of nerve endings, especially in areas like the skin, where sensory functions such as touch, pressure, and pain are critical.
4. Eliminate incorrect options: 'No innervation' is incorrect because epithelial tissues do have nerve supply. 'Poor innervation' and 'variable innervation' are also incorrect because epithelial tissues generally have consistent and good innervation.
5. Conclude that the correct answer is 'good': Based on the functional and structural characteristics of epithelial tissues, they are well-innervated to support their sensory and regulatory roles.
