Sublingual salivary gland (glangula sublingualis) is a paired, predominantly mucosal-type secretion. Located on the jaw-hyoid muscle, directly under the mucous membrane of the bottom of the mouth. The lateral surface touches the inner surface of the body of the lower jaw in the region of the same pit. The medial side of iron is attached to the chin, the chin, and the sublingual-lingual muscles. A large duct (ductus sublingualis major) - the main excretory duct opens on the same papilla. Several small ducts (ductus sublinguals minores), which are additional for salivating, enter the oral cavity on the surface of the same fold.
Numerous small channels open along the fold. There are five intermuscular cracks through which the pathological process quickly spreads to neighboring structures. Outside and anteriorly there is a space of the maxillofacial groove where the lingual nerve, the duct of the submandibular SJ with the surrounding gland lobe and the eponymous nerve with the lingual vein pass. This is the most "weak" place in space. Sublingual cell space also communicates with the anterior near-pharyngeal space along the hypoglossal muscle and its fascial case.
Innervation: secretory (parasympathetic) - fibers of the facial nerve, through the drum string and node, sympathetic - from the outer sleeping plexus.
Blood supply: chin artery. Venous outflow: veins.
Outflow of lymph: in the submandibular and chin lymph nodes.
