The retromolar area of a human mandible is covered by the retromolar pad (also known as the piriformis papilla), an elevated triangular area of mucosa.It is composed of non-keratinized loose alveolar tissue covering glandular tissues and muscle fibers. [4]
The retromandibular vein (temporomaxillary vein, posterior facial vein) is a major vein of the face. It is formed within the parotid gland by the confluence of the maxillary vein, and superficial temporal vein. It descends in the gland and splits into two branches upon emerging from the gland.
From its origin it runs obliquely downward and backward, beneath the zygomaticus major muscle and zygomatic head of the levator labii superioris, descends along the anterior border and then on the superficial surface of the masseter, crosses over the body of the mandible, and passes obliquely backward, beneath the platysma and cervical fascia, superficial to the submandibular gland, the ...

The mandibular nerve, the third branch of the trigeminal nerve (CN V 3), also known as the "inferior maxillary nerve", enters infratemporal fossa from the middle cranial fossa through the foramen ovale of the sphenoid bone.
Diagram showing left medial and lateral pterygoid muscles. Part of the zygomatic arch and the ramus of the mandible have been cut away. The pterygomandibular space lies between the lateral surface of medial pterygoid and the medial surface of the mandibular ramus.
The maxillary vein and the superficial temporal vein later join to become the retromandibular vein. The posterior branch of the retromandibular vein and posterior auricular vein then form the external jugular vein, which empties into the subclavian vein. [citation needed]
The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas).The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine.
