Final answer:
The structures between the mandible and medial pterygoid mm are the articular tubercle, foramen ovale, and stylomastoid foramen.
Step-by-step explanation:
Between the mandible and the medial pterygoid muscles, there are three structures:
- Articular tubercle: Located on the temporal bone, it is part of the temporomandibular joint and helps with jaw movements.
- Foramen ovale: This is an opening in the sphenoid bone that allows nerves and blood vessels to pass through.
- Stylomastoid foramen: Found in the temporal bone, it is an opening for the facial nerve.
The medial pterygoid muscles provide assistance in chewing by moving the mandible side to side, alongside the lateral pterygoid muscles that occupy the infratemporal space and attach to the lateral pterygoid plate. The TMJ allows for various movements of the jaw, including opening, closing, and side-to-side motions.
