Which anatomical structure wraps around the parotid gland, forming its capsule?

The mandibular ramus is the bony structure that wraps around (overlies) the parotid gland anteriorly and laterally. The parotid gland is lodged in the parotid space bounded by: the mandibular ramus anteriorly, the external auditory meatus superiorly, the mastoid process and sternocleidomastoid muscle posteriorly. The masseter muscle overlies the parotid superficially in the cheek area, but the ramus is the key wrapping structure in classic anatomy teaching.
