Final answer:
The mandibular fossa receives the condyle of the mandible and is involved in the temporomandibular joint and chewing.
Step-by-step explanation:
The mandibular fossa receives the condyle of the mandible, which is the rounded surface on the back of the lower jaw. The condyle articulates with the mandibular fossa to form the temporomandibular joint, allowing for movements of the mandible during opening and closing of the mouth. The mandibular fossa is also involved in chewing, as it contains muscles that act on the mandible.
