| − | ==Introduction==
| |
| − | | |
| − | The [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]] is drained by numerous salivary glands. The saliva secreted keeps the mouth moist and facillitates [[Mastication|mastication]] by lubricating the passage of the bolus.
| |
| − | | |
| − | Salivary gands are present in the [[Cheeks - Anatomy & Physiology|cheek]], [[Oral Cavity - Tongue - Anatomy & Physiology|tongue]], [[Lips - Anatomy & Physiology|lips]], oesophagus, [[Soft Palate - Anatomy & Physiology|soft palate]] and pharynx but the major salivary glands are located further away from the [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]] and function through connective ducts. | |
| − | | |
| − | Saliva provides digestive enzymes, is a route of excretion of substances which accumulate on the [[Tooth Anatomy - Anatomy & Physiology|teeth]] and provides lubricative and also cleansing functions.

| − | ==Types of Salivary Glands==
| |
| − | | |
| − | '''Major Salivary Glands'''
| |
| − | | |
| − | *[[Parotid]] (glandula parotis)
| |
| − | | |
| − | *[[Mandibular]] (glandula mandibularis)
| |
| − | | |
| − | *[[Sublingual]] (glandula sublinguales)
| |
| − | | |
| − | *[[Zygomatic]] (glandula zygomatica)
| |
| − | | |
| − | '''Minor Salivary Glands'''
| |
| − | | |
| − | *[[Labial]]
| |
| − | | |
| − | *[[Lingual]]
| |
| − | | |
| − | *[[Buccal]]
| |
| − | | |
| − | *[[Palatine]]
| |

| − | ==Innervation==
| |
| − | | |
| − | *Sympathetic
| |
| − | -Vasoconstriction occurs
| |
| − | -Flow of saliva is decreased
| |
| − | | |
| − | *Parasympathetic (most important)
| |
| − | -Travel from the brainstem by the facial (CN VII) and glossopharyngeal (CN IX) then into
| |
| − | branches of the trigeminal nerve (CN V)
| |
| − | -Flow of salivary fluid increases
| |
| − | -Vasodilation occurs
| |
| − | | |
| − | *Main nerves are occulomotor (CN III), facial (CN VII), glossopharyngeal (CN IX) and vagus (CN X)
