What muscle attaches to the mandible?
masseter muscle
The masseter muscle fibers converge inferiorly, forming a tendon that inserts the outer surface of the mandibular ramus and coronoid process of the mandible.
Which muscle inserts on the coronoid process?
Temporal muscle
| Origin | Temporal fossa (up to inferior temporal line), Temporal fascia |
|---|---|
| Insertion | Apex and medial surface of coronoid process of mandible |
| Action | Anterior fibres: Elevates mandible Posterior part: Retracts mandible |
| Innervation | Deep temporal branches (of mandibular nerve (CN V3)) |
What does coronoid process connect?
The coronoid process, as previously mentioned, is the foremost structure at the head of the ramus, attaches to the temporalis muscle, which is utilized during mastication.
How many muscles are attached to the mandible?
The four main muscles of mastication originate from the surface of the skull and they attach onto the rami of the mandible at the TMJ.
What is coronoid process of mandible?
In human anatomy, the mandible’s coronoid process (from Greek korone, “like a crow”) is a thin, triangular eminence, which is flattened from side to side and varies in shape and size. Its anterior border is convex and is continuous below with the anterior border of the ramus.
Which muscles elevate the mandible quizlet?
The medial pterygoid helps to elevate the mandible, while the lateral pterygoid protracts its.
Which muscle attaches to the coronoid process of the mandible quizlet?
The temporalis muscle, which originates on the temporal fossa, inserts onto the coronoid process of the mandible, working to elevate the mandible.
What muscle attaches to the coronoid process of the ulna?
It is the site of insertion of the tendon of the triceps brachii muscle. The coronoid process extends anteriorly from the distal base of the trochlear notch.
Which of the following muscles insert onto the coronoid process of the ulna?
What are the processes of the mandible?
The ramus of the mandible contains three prominent processes: the coronoid process on the dorsal aspect, the condylar process caudally, and the angular process caudoventrally. The maxillary teeth are located in the maxillary and incisive bones.
What is the coronoid process in dentistry?
Coronoid process – The coronoid process of the mandible is the triangular bony portion of the anterosuperior aspect of the ramus. This mandibular structure can be recorded on maxillary molar periapicals as the ramus moves forward when the patient’s mouth is open.
Which of the following muscles has an insertion on the mandible quizlet?
The masseter also protracts the mandible; it originates on the zygomatic arch and inserts on the mandible (external surface of angle and ramus). The temporalis muscle additionally retracts the mandible. Its origin is the temporal bone (fossa) and its insertion is the mandible (coronoid process and ramus).
What is the coronoid process of the mandible?
Coronoid process of the mandible. Its posterior border is concave and forms the anterior boundary of the mandibular notch. The lateral surface is smooth, and affords insertion to the temporalis and masseter muscles. Accordingly, what is attached to the Coronoid process?
What is the coronoid process of the ramus?
The coronoid process, as previously mentioned, is the foremost structure at the head of the ramus, attaches to the temporalis muscle, which is utilized during mastication.
What does the coronoid process project anteriorly?
The coronoid process projects anteriorly and bears a tubercle on its medial side, to which is attached part of the medial collateral ligament of the elbow joint. Just distal to this are the ulnar heads of the flexor digitorum superficialis and pronator teres muscles and an occasional head of flexor pollicis longus.
What is a coronoid process fracture?
Coronoid process fractures. Mandible fractures are common injuries. However, coronoid process fractures are very rare. Isolated fractures of the coronoid process caused by direct trauma are rare, as it is anatomically protected by the complex zygomatic arch/ temporo-zygomatic bone and their associated muscles.
