Question

Coronoid process of mandible- Takes its name from the Greek word for crow because it is curved like a crow's beaks this is where the temporals muscle attaches to the jawbone.

A) The coronoid process is where the masseter muscle attaches to the jawbone.
B) The coronoid process is flat and not curved.
C) The coronoid process is named after a Greek philosopher.
D) The coronoid process is curved like a crow's beak and where the temporal muscle attaches to the jawbone.

Answer 1

The coronoid process of the mandible is a flattened structure named for its D.crow's beak-like shape, where the temporal muscle attaches. It should not be confused with other structures such as the condylar process or styloid process.

Step-by-step explanation:

Coronoid Process of the Mandible

The coronoid process of the mandible is one of the upward bony projections from the anterior margin of the mandibular ramus. It is a flattened structure that provides attachment for one of the biting muscles. The name coronoid derives from its shape, which is reminiscent of a crow's beak (corvus in Greek). However, it is the temporal muscle that attaches at the coronoid process for the function of elevating the mandible during biting and chewing.

The temporal muscle is one of the major muscles involved in moving the jaw, but not the masseter muscle, which attaches elsewhere on the mandible. The styloid process, on the other hand, serves as an attachment site for several small muscles and a ligament that supports the hyoid bone of the neck. Furthermore, the coronoid process should not be confused with the condylar process, which is located posteriorly on the mandibular ramus and forms part of the temporomandibular joint.
