What is in submandibular fossa?
Quick Reference. A shallow depression on the inner surface of the mandible below the mylohyoid line in which lies the submandibular salivary gland.
Where is submandibular fossa located?
posterior mandible
Submandibular fossa – The submandibular fossa is a depression in bone on the lingual aspect of the posterior mandible. The fossa is located bilaterally below the internal oblique ridge or mylohyoid line. This concavity is where the submandibular salivary gland rests.
What is the sublingual fossa?
The sublingula fossa is a smooth triangular area against which the sublingual gland rests, above the anterior part of the mylohoid line.
What is submandibular region?
The submandibular region lies between the mandible and hyoid bones and is formed by the submental and submandibular triangles. It contains the submandibular gland. In adults the mandible, which normally contains 16 permanent teeth, articulates with the temporal bone of the skull through the temporomandibular joint.
What is parotid space?
The parotid space is one of the deep compartments of the head and neck and, as the name suggests, is mostly filled with the parotid gland. It is the most lateral major suprahyoid neck space.
What is the Lingula of mandible?
The lingula of the mandible (also known as Spix spine) is a triangular bony projection or ridge on the medial surface of the ramus of the mandible, immediately superior to the mandibular foramen. It provides attachment for the sphenomandibular ligament 1,2.
What is mental fossa?
Mental fossa – The mental fossa is a depression in the bone on the labial aspect of the mandible. It has a diffuse radiolucent appearance above the mental ridge. The mental fossa varies in its prominence depending on the thickness and density of the anterior mandible.
What Innervates sublingual glands?
Innervation. The nervous supply of the sublingual gland reflects that of the submandibular gland. It occurs via the chorda tympani, which carries fibers that originate from the facial nerve (CN VII) and are classed as secretomotor fibers.
What is sublingual region?
The sublingual space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space located below the mouth and above the mylohyoid muscle, and is part of the suprahyoid group of fascial spaces.
What is hilum of submandibular gland?
The Wharton duct originates at the submandibular gland hilum and then travels around the posterior portion of the mylohyoid muscle. The duct then crosses paths medially with the lingual nerve while traveling superiorly, eventually opening into the oral cavity at the sublingual caruncula.
