Gingiva is supplied by
**Core Concept**
The gingiva, also known as the gums, is a part of the oral cavity that surrounds and supports the teeth. It plays a crucial role in maintaining oral health and is innervated by sensory nerves that provide proprioception and pain sensation. The blood supply to the gingiva is crucial for its health and function.
**Why the Correct Answer is Right**
The gingiva is supplied by the alveolar arteries, which are branches of the maxillary and mandibular arteries. These arteries are responsible for supplying oxygenated blood to the gingiva, and their integrity is essential for maintaining healthy gingival tissue. The gingiva also receives nerve supply from the inferior alveolar nerve and the superior alveolar nerves, which provide sensation to the teeth and surrounding tissues.
**Why Each Wrong Option is Incorrect**
**Option A:** The lingual artery primarily supplies the tongue and the floor of the mouth, not the gingiva.
**Option B:** The facial artery primarily supplies the face, including the skin and muscles, but not the gingiva.
**Option C:** The palatine arteries primarily supply the palate, not the gingiva.
**Clinical Pearl / High-Yield Fact**
The gingiva is a highly vascularized tissue that is sensitive to changes in blood flow and oxygen tension. This is why periodontal disease can often be a sign of underlying systemic vascular disease.
**Correct Answer:** C.
