− | The oral cavity is the first section of the alimentary tract that recieves food. It provides the digestive functions of prehension, [[Mastication|mastication]] and insalivation and also plays a role in the [[Cardiorespiratory System - Anatomy & Physiology|respiratory system]] through oral breathing when the [[Nasopharynx - Anatomy & Physiology|nasopharynx]] is impaired.

− | The oral cavity or mouth, consists of accessory structures (the [[Oral Cavity - Salivary Glands - Anatomy & Physiology|salivary glands]]), projecting structures (the [[Tooth Anatomy - Anatomy & Physiology|teeth]] and [[Oral Cavity - Tongue - Anatomy & Physiology|tongue]]) and the walls enclosing the oral cavity. | + | The oral cavity is the first section of the alimentary tract that receives food.

The [[Tongue - Anatomy & Physiology|tongue]] margins ventrally. The size can be altered by raising or lowering the [[Tongue - Anatomy & Physiology|tongue]] and the floor of the oral cavity when the mouth is closed. |

| | | |
− | *Palate dorsally
| + | The oral cavity originates from ectoderm. It is innervated by the '''trigeminal nerve''' ([[Cranial Nerves - Anatomy & Physiology|CN V]]). |
