Depends... On a male, 90 degrees. On a female, 120 degrees.
The masseter muscle is the chewing muscle covering the angle of the mandible. During bilateral contraction, the muscle elevates the mandible, raising the lower jaw.
The masseter inserts on the mandible, specifically on the angle and ramus. The temporalis inserts on the coronoid process of the mandible. The lateral pterygoid inserts on the condyloid process of the mandible, while the medial pterygoid inserts on the angle of the mandible.
The ascending part of the mandible is the vertical portion of the mandible bone that extends from the mandibular angle to the coronoid process. It forms the posterior border of the ramus of the mandible and provides attachment for muscles involved in chewing and jaw movement.
The masseter muscle originates on the zygomatic arch and inserts on the angle of the mandible. It is responsible for elevating the mandible during jaw closure and is one of the key muscles involved in chewing.
A right angle.
An obtuse angle is an angle of more than 180 degrees.
what is bite angle in rolling mill
- head or condyle - mandibular notch or condular notch - neck ~just under the condyle - ramus - body - angle - mental foramen - protuberance~ the chin - alveolar processes of the mandible - oblique line
critical angle is defined as angle of incidence provide an anlge of refraction of 90 degree
