The submandibular gland and tongue are described. The submandibular gland is J-shaped and located in the digastric triangle below the mandible. It has superficial and deep parts divided by the mylohyoid muscle. The submandibular duct drains saliva from the gland into the floor of the mouth. The tongue has intrinsic and extrinsic muscles that aid in speech, taste, chewing and swallowing. Both structures receive blood supply from the facial artery and have lymphatic drainage to submandibular lymph nodes.
