The term "glandula salivalis externa" refers to the external salivary gland in Latin. It is a tubular organ found in various regions of the body, primarily in vertebrates, that secretes saliva. Saliva is a clear and watery fluid that is essential for the process of digestion and maintaining oral health.
The glandula salivalis externa plays a crucial role in producing and delivering saliva to the oral cavity. It consists of a network of ducts and secretory units that produce and transport the saliva. These glands are primarily located around the mouth and face, including the parotid glands near the ears, submandibular glands under the jaw, and sublingual glands below the tongue.
The saliva produced by the glandula salivalis externa serves various functions in the body. It helps to moisten and lubricate food, facilitating swallowing and digestion. Saliva also contains enzymes that begin the breakdown of food particles, aiding in the digestion process. Additionally, it helps to maintain oral hygiene by preventing dryness, neutralizing acidity, and reducing the risk of tooth decay.
Disorders affecting the glandula salivalis externa can lead to various conditions, such as salivary gland infections, salivary stones, and salivary gland tumors. These conditions can cause pain, swelling, difficulty eating or speaking, and require medical attention.
In summary, the glandula salivalis externa refers to the external salivary glands responsible for producing and delivering saliva in the oral cavity. It plays a vital role in digestion, oral health, and maintaining overall well-being.
