Salivary Glands

From WikiLectures

The salivary glands consist of: Parotid, Sublingual and Submandibular glands.

1. Parotid gland 2. Submandibular gland 3. Sublingual gland

Parotid Gland[✎ edit | edit source]

  • It is the largest of all three glands
  • It is located on the anterior, lower half of the ear
  • It has an excretory duct.
  • Parasympathetic innervation is by glossopharyngeal nerve

Sublingual and Submandibular Gland[✎ edit | edit source]

  • They are mixed seromucous glands
  • They have an excretory duct
  • Parasympathetic innervation is by chorda tympani (from the superior salivatory nucleus) and a branch of the facial nerve (which synapses with the submandibular ganglion, follows the lingual nerve and leaves the lingual nerve when it is near to the glands[1]

Sublingual Gland

  • It is the smallest salivary gland
  • It is almond-shaped
  • It is lateral to the submandibular duct
  • It is associated with the lingual nerve on the floor of the oral cavity
  • The gland lies against the medial surface of the mandible, where it forms the sublingual fossa, lying superior to the anterior 1/3 of the mylohyoid gland

Submandibular gland

  • It is on the medial side of the mandible in the submandibular fossa, which is inferior to the mylohyoid line
  • The larger arm of the hook is directed forward in the horizontal plane; below the mylohyoid muscle
  • The smaller arm loops around the posterior margin of the mylohyoid muscle
