Which muscles insert on the mandible?
Muscles Inserting on the Mandible
- Platysma – inserts on the inferior border of the mandible.
- Superficial masseter – inserts on the lateral surface of the ramus and angle of the mandible.
- Deep masseter – inserts on the lateral surface of the ramus and angle of the mandible.
How long does it take to heal a broken humerus?

Is the humerus distal to the radius?
Humerus: The humerus attaches proximally to the scapula (shoulderblade) at the humeral head and distally with the radius and ulna (lower-arm bones) at the trochlea and capitulum, respectively. The proximal portion of the humerus can be divided into three parts.

Which is the most lateral part of the humerus?
The greater tubercle is the most lateral part of the proximal end of the humerus. Three impressions mark it at the upper posterior aspect, all of which serve for the attachment of muscles. From superior to inferior, the muscles that attach at these impressions are three of the rotator cuff muscles:
Where are the muscular attachments of the mandible?
The lateral pterygoid inserts into the neck of the mandible, and the medial pterygoid inserts into the ramus near the angle of the mandible. Fig 3 – Muscular attachments to the mandible. The mandible articulates with the temporal bone to form the temporomandibular joint which is discussed in more detail here.
