The depressor mandibulae, also known as the depressor anguli oris in some contexts, is a muscle located in the lower jaw region. Its primary function is to lower the mandible (jawbone), facilitating actions such as opening the mouth. It also plays a role in facial expressions, particularly in movements that convey sadness or frowning. This muscle is innervated by the facial nerve (cranial nerve VII).
