Which of the following structures contains gustatory receptors responsible for detecting taste stimuli on the tongue?

• A. Filiform papillae
• B. Fungiform papillae
• C. Vallate papillae
• D. Foliate papillae

Answer: (B)

Verified step by step guidance

1. Understand the context: Gustatory receptors are specialized sensory cells responsible for detecting taste stimuli. These receptors are located on the tongue within specific structures called papillae.
2. Review the types of papillae: The tongue contains four main types of papillae: filiform, fungiform, vallate, and foliate. Each type has a distinct structure and function.
3. Eliminate filiform papillae: Filiform papillae are the most numerous on the tongue but do not contain gustatory receptors. Their primary function is to provide texture and help manipulate food.
4. Focus on the remaining options: Fungiform papillae, vallate papillae, and foliate papillae all contain gustatory receptors. These structures house taste buds, which are clusters of sensory cells that detect taste stimuli.
5. Identify the correct answer: Fungiform papillae are small, mushroom-shaped structures located on the anterior part of the tongue. They contain taste buds and are responsible for detecting taste stimuli, making them the correct answer in this context.
