Study Notes
Submandibular Gland Anatomy
- The deep part of the submandibular gland is covered by the stylohyoid muscle and the posterior belly of the digastric muscle.
- The submandibular gland is classified as a mixed gland, producing both serous and mucous secretions.
Innervation and Secretion
- Parasympathetic stimulation produces a serous secretion in the submandibular gland.
- The submandibular ganglion is connected to the lingual nerve and receives parasympathetic fibers from it.
- The functional relationship of the submandibular ganglion is to relay parasympathetic secretomotor fibers to the submandibular gland.
Location and Relations
- The submandibular gland is suspended from the stylohyoid muscle and the posterior belly of the digastric muscle.
- The superficial part of the submandibular gland extends up to the anterior border of the mandible.
- The submandibular gland is surrounded by a fascial covering or capsule, which is derived from the deep cervical fascia.
- The lateral surface of the submandibular gland is related to the submandibular fossa of the mandible, the medial pterygoid muscle, and the facial vein.
- The body of the submandibular gland is described as having two ends, an anterior and a posterior end.
Blood Supply and Lymphatic Drainage
- The blood supply to the submandibular gland is mainly from the facial artery and the lingual artery.
- The lymphatic drainage of the submandibular gland is to the submandibular lymph nodes.
Pathology and Management
- Calculi of the submandibular gland duct are typically managed by removing the stone or by excising the submandibular gland.
Size and Weight
- The weight of the submandibular gland ranges from 7 to 15 grams.
Neuroanatomy
- The submandibular ganglion is a small, oval-shaped ganglion located above the submandibular gland.
- The lingual nerve carries parasympathetic fibers to the submandibular gland.
