Nuhn’s glands are present on

The correct answer is tongue.

Step-by-Step Explanation:

1. Understanding Nuhn's Glands:
Nuhn’s glands, also known as the anterior lingual glands or glands of Blandin and Nuhn, are a pair of small, mixed mucous and serous salivary glands.

2. Anatomical Location:
These glands are embedded within the muscular tissue on the ventral (under) surface of the tongue, near its apex (tip). They open via several small ducts onto the under surface of the tongue.

3. Reviewing the Options:
- Stomach: The stomach contains gastric glands, not salivary glands like Nuhn's glands.
- Skin: The skin contains sweat glands (sudoriferous glands) and oil glands (sebaceous glands).
- Tongue: This is the correct anatomical site where Nuhn’s glands are located.
- Intestine: The intestine contains intestinal glands (Crypts of Lieberkühn) and Brunner's glands (in the duodenum).

Therefore, Nuhn’s glands are situated specifically on the tongue.
