Anatomical terms of bone
In human anatomy, the mandible's coronoid process (from Greek korone, "like a crown") 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.

Likewise, people ask, how do you palpate the coronoid process of the mandible?

Procedure. Palpate the area near the highest point on the zygomatic arch and the caudal border of the coronoid process of the mandible. A depression is felt caudal to the coronoid process. The nerve itself can often be palpated crossing the apex of the coronoid process in a horizontal direction (see Figs.

One may also ask, how does the mandible form? The mandible forms as a bone (ossifies) over time from a left and right piece of cartilage called Meckel's cartilages. These cartilages form the cartilaginous bar of the mandibular arch.

Then, what is the function of the Coronoid process?

The coronoid process is a triangular eminence projecting forward from the upper and front part of the ulna. Its base is continuous with the body of the bone, and of considerable strength. Its medial surface, by its prominent, free margin, serves for the attachment of part of the ulnar collateral ligament.

What is the Ramus of the mandible?

Ramus of the mandible: One of the two prominent, projecting back parts of the horseshoe-shaped lower jaw bone.

What attaches to the Coronoid process?

Coronoid process of the ulna. Upper extremity of left ulna. Lateral aspect. At the junction of this surface with the front of the body is a rough eminence, the tuberosity of the ulna, which gives insertion to a part of the brachialis; to the lateral border of this tuberosity the oblique cord is attached.

What muscles attach to Coronoid process of mandible?

The temporalis muscle attaches to the coronoid process, and the masseter attaches to the rami. The lateral pterygoid inserts into the neck of the mandible, and the medial pterygoid inserts into the ramus near the angle of the mandible.

What does the coracoid process feel like?

Palpate gently as the coracoid process is sensitive. humeral head Palpate in the axilla, posterior to the tendon of the pectoralis major. Passively abduct your partner's arm to feel the head move inferiorly. greater tuberosity This structure is located about 1/2" below the lateral edge of the anterior acromion process.

What is the olecranon process?

1. olecranon process - process of the ulna that forms the outer bump of the elbow and fits into the fossa of the humerus when the arm is extended. olecranon. appendage, outgrowth, process - a natural prolongation or projection from a part of an organism either animal or plant; "a bony process"

Where does the Coronoid process articulate?

…of the trochlear notch, the coronoid process, enters the coronoid fossa of the humerus when the elbow is flexed. On the outer side is the radial notch, which articulates with the head of the radius. The head of the bone is elsewhere roughened for muscle attachment.

Where is the Coronoid fossa located?

(Coronoid fossa visible at bottom center, on left side.) Superior to the anterior portion of the trochlea is a small depression, the coronoid fossa, which receives the coronoid process of the ulna during flexion of the forearm. It is directly adjacent to the radial fossa of the humerus.

Where is the Trochlear notch located?

The trochlear notch (also semilunar notch, or greater sigmoid cavity) is a large depression in the upper extremity of the ulna that fits the trochlea of the humerus (the bone directly above the ulna in the arm) as part of the elbow joint. It is formed by the olecranon and the coronoid process.

What is the function of the capitulum?

In human anatomy of the arm, the capitulum of the humerus is a smooth, rounded eminence on the lateral portion of the distal articular surface of the humerus. It articulates with the cupshaped depression on the head of the radius, and is limited to the front and lower part of the bone.

What is a Coronoid process fracture?

The coronoid process of the ulna is one of the bony structures that can be fractured and has an important role in the stability of elbows after dislocation. Coronoid fractures are relatively uncommon injuries occurring in approximately 2% to 15% of patients with dislocation.

What is the Coronoid notch?

an indentation, especially one on the edge of a bone or other organ; called also incisure. Rivinus' notch (tympanic notch) a defect in the upper tympanic part of the temporal bone, filled by the upper portion of the tympanic membrane.

What does the coracoid process articulate with?

The coracoid process articulates with the humerus (upper-arm) and clavicle ('collar') bones. The coracoid process forms a point of attachment to several muscles, specifically the short head of biceps, the coraco brachialis, the pectoralis minor and also the the *costo-coracoid and *conoid ligaments.

What does the Coronoid fossa articulate with?

The coronoid fossa articulates with the coronoid process of the ulna, and the radial fossa articulates with the radial head of the radius. Moreover, just inferior to the coronoid fossa, the capitulum and the trochlea can be identified which promote articulation with the radius and the ulna.

What muscles attach to the olecranon process?

The olecranon is a bony prominence of the ulna that represents that bone's most proximal posterior surface at the elbow. While the olecranon is an attachment site for several muscle groups including the flexor carpi ulnaris and anconeus, the major muscle attachment is that of the triceps.

What articulates with the coracoid process?

The acromial end of the clavicle articulates with the acromion of the scapula at the acromioclavicular joint. This end is also anchored to the coracoid process of the scapula by the coracoclavicular ligament, which provides indirect support for the acromioclavicular joint.

What are the parts of the mandible?

The body of the mandible is located in the anterior part of the lower jawbone, has a curved shape, and can be divided in two parts: the base of the mandible, and the alveolar part of the mandible. The body of the mandible has two surfaces (external, internal) and two borders (superior or alveolar, and inferior).
