lateral pterygoid, digastric, mylohyoid andgeniohyoid muscles
Yes, the mandible can be elevated and depressed. Elevation occurs when the jaw closes, bringing the teeth together, primarily through the action of the masseter and temporalis muscles. Depression happens when the jaw opens, allowing the mouth to open wider, facilitated by the digastric and mylohyoid muscles. These movements are essential for functions such as chewing and speaking.
The temporalis and masseter muscles are the primary muscles responsible for raising the mandible (lower jaw) during the process of chewing or biting. These muscles work together to produce the necessary force to close the mouth and elevate the mandible.
The temporalis muscle acts to elevate and retract the mandible (lower jaw) during the process of chewing. It is one of the main muscles involved in mastication (chewing) and helps in closing the mouth during jaw movements.
Gravity plays a large part in opening the jaw, but there are muscles that help forcefully open your jaw. The most important of these is the digastric muscle, which connects from the mastoid process of the temporal bone to the hyoid bone, and then from the hyoid bone to the digastric fossa of the mandible.

Sublingual and a portion of submandibular (lateral to sublingual) salivary gland.
The movement that causes your mouth to open is primarily the contraction of the digastric and mylohyoid muscles, which are located in the jaw area. These muscles work together to lower the mandible (the lower jaw), allowing the mouth to open. Additionally, the lateral pterygoid muscle plays a role by facilitating the forward movement of the jaw. This coordinated action allows for functions such as speaking, eating, and breathing.
The principal muscle of mastication that closes the mouth is the masseter muscle. This powerful muscle is located at the back of the jaw and plays a key role in elevating the mandible to facilitate chewing. It works in conjunction with other muscles, such as the temporalis and pterygoid muscles, to enable effective movement of the jaw during mastication.
The mandible is the jawbone and is located in the lower part of the face, beneath the mouth. It is the largest and strongest bone in the human face.
