What tendons attach to the coracoid process?
The coracoid process serves as the attachment site for several muscles. The pectoralis minor is attached to the medial aspect of the coracoid. The coracobrachialis is attached to the tip of the process on the medial side, and the short head of the biceps is attached to the tip of the process on the lateral side.
Correspondingly, what 3 muscles attach to coracoid process?
It is the site of attachment for several structures:
- The pectoralis minor muscle – to 3rd, 4th, 5th and on some rare occasions, 6th rib.
- The short head of biceps brachii muscle – to Radial tuberosity.
- The coracobrachialis muscle – to medial humerus.
- The coracoclavicular ligament – to the clavicle.
One may also ask, what muscle attaches to Coronoid process? 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.
Likewise, people ask, where is the coracoid process?

coracoid process Find the most concave dip in the clavicle and drop inferiorly about 1" to locate this structure. Palpate gently as the coracoid process is sensitive. Confirm its location by passively moving your partner's GH joint through 15° to 30° abduction-adduction.
What is coracoid impingement?
👉 Discover more in this in-depth guide.
Abstract. Coracoid impingement syndrome is a less common cause of shoulder pain. Symptoms are presumed to occur when the subscapularis tendon impinges between the coracoid and lesser tuberosity of the humerus.
What is a coracoid fracture?
Coracoid process fractures are an uncommon type of scapular fracture. They do not often occur in isolation and are often associated with acromial, clavicular, or scapular fracture, as well as humeral head dislocation. In general, the coracoid process tends to fracture at its base and be minimally displaced.
Where do lats attach?
As the muscle fibers of the lats extend from the origin to the insertion point (the insertion for the lats is located on the inner aspect of your upper arm bone, just below the shoulder joint) they taper into a point.
What is the glenohumeral joint?
The shoulder joint (glenohumeral joint) is a ball and socket joint between the scapula and the humerus. It is the major joint connecting the upper limb to the trunk. It is one of the most mobile joints in the human body, at the cost of joint stability.
What's the pectoral girdle?
Anatomical terms of bone
The shoulder girdle or pectoral girdle is the set of bones in the appendicular skeleton which connects to the arm on each side. In humans it consists of the clavicle and scapula; in those species with three bones in the shoulder, it consists of the clavicle, scapula, and coracoid.How many Scapulas do we have?
The scapula is ossified from 7 or more centers: one for the body, two for the coracoid process, two for the acromion, one for the vertebral border, and one for the inferior angle.
Do humans have a Coracoid?
A coracoid is a paired bone which is part of the shoulder assembly in all vertebrates except therian mammals (marsupials and placentals). In therian mammals (including humans), a coracoid process is present as part of the scapula, but this is not homologous with the coracoid bone of most other animals.
What muscles attach to the scapula?
The scapula provides attachment sites for many muscles including the pectoralis minor, coracobrachialis, serratus anterior, triceps brachii, biceps brachii, and the subscapularis. The scapula has two main surfaces: the costal (front facing) surface and the dorsal (rear facing) surface.
How do you palpate Coracobrachialis?
Positioning: client supine with arm resting at the side.
- Locate the anterior border of the axilla.
- Palpate posteriorly and laterally along the medial surface of the humerus.
- Locate the muscle belly deep and medial to the biceps brachii, following toward its insertion on the medial shaft of the humerus.
What is Coronoid fossa?
n. A hollow on the anterior surface of the distal end of the humerus, just above the trochlea, in which the coronoid process of the ulna rests when the elbow is flexed.
What does the acromion process feel like?
The articulation connection lets two bones move together, which is exactly how our acromion process and our clavicle work in tandem. The acromion process is the part of our shoulder blade, or scapula, that you can feel sticking up if you rub where the back of your shoulder meets your arm.
What is a bone process?
In anatomy, a process (Latin: processus) is a projection or outgrowth of tissue from a larger body.
Where is the glenoid cavity located?
The glenoid cavity or glenoid fossa of scapula is a part of the shoulder. It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula.
How long does it take for a fractured coracoid to heal?
This treatment resulted in complete recovery after 8 weeks and return to full sports on first league level after 3 month. In conclusion, non-operative treatment of coracoid base fractures with concomitant AC-joint injury in the adolescent can result in excellent functional results and early recovery.
What action S does the triceps perform at the shoulder?
The main action of the triceps brachii muscle is to extend the forearm, which involves straightening the arm at the elbow joint. This muscle also helps to stabilize the humerus within the shoulder joint.
What is the shoulder?
The shoulder is one of the largest and most complex joints in the body. The shoulder joint is formed where the humerus (upper arm bone) fits into the scapula (shoulder blade), like a ball and socket. The clavicle (collarbone) meets the acromion in the acromioclavicular joint.
What does the Coronoid process do?
n. The triangular anterior process of the mandibular ramus, giving attachment to the temporal muscle. A bracketlike projection from the anterior portion of the proximal extremity of the ulna, giving attachment to the brachial muscle and entering into formation of the trochlear notch.
What does the Coronoid process articulate with?
trochlea of the humerus
