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.

What muscle attach to the coracoid process?

The pectoralis minor muscle is found deep to the pectoralis major. It originates from the anterior aspect of the third through fifth ribs and inserts onto the superior aspect of the coracoid process along the medial border.

How many ligaments attach to the coracoid process?

Coraco-clavicular Ligaments (CCL):

These two ligaments (trapezoid and conoid ligaments) attach the clavicle coracoid process of the scapula.

How many muscles attach to coracoid process?

Three muscles attach to the coracoid process, the little bony projection of the scapula that sticks out just inferior to the acromioclavicular joint. These are just three of myriad muscles that attach to some aspect of the shoulder blade.

What articulates with the coracoid process?

The coracoid articulates with the forward edge of the sternum and with the scapula, humerus, and furcula.

What connects the coracoid and the acromion processes?

The coracoacromial ligament (CAL) connects the acromion and coracoid process of the scapula, forming an osseoligamentous static restraint to superior humeral head displacement.

What does the scapula attach to?

The scapula is a flat, triangular-shaped bone (colloquially as the “shoulder blade”). It is located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint.

What holds the humerus in place?

The humerus is held in place with ligaments, tendons and muscles. These important tendons and muscles include the rotator cuff muscles, biceps tendon, and the deltoid muscle discussed above.

What muscles attach to acromion process?

Two major muscles, the deltoid and trapezius, attach to the acromion. The deltoid, which abducts the arm at the shoulder, forms its origin along the acromion, the spine of the scapula, and the clavicle. From these origins, it crosses the shoulder joint and inserts on the deltoid tuberosity of the humerus.

What muscle attaches to the deltoid tuberosity?

The deltoid tuberosity of the humerus lies proximally about a third of the way to the elbow and provides an attachment point for the deltoid muscle. The deltoid is a triangular muscle with three attachment points: the humerus, the clavicle, and the scapula.

What muscles attach to the medial border of the scapula?

Four muscles attach to the medial border. Serratus anterior has a long attachment on the anterior lip. Three muscles insert along the posterior lip, the levator scapulae (uppermost), rhomboid minor (middle), and to the rhomboid major (lower middle).

Is the coracoid process anterior or posterior?

The coracoid process is an anteriorly projecting hook-like process on the superolateral edge of the scapula that projects anterolaterally.

Where is Olecranal?

The olecranon /oʊˈlɛkrənɒn/, from the Greek olene meaning elbow and kranon meaning head, is a large, thick, curved bony eminence of the ulna, a long bone in the forearm that projects behind the elbow. It forms the most pointed portion of the elbow and is opposite to the cubital fossa or elbow pit.

How does the coracoid process work?

The coracoid process (from Greek κόραξ, raven) is a small hook-like structure on the lateral edge of the superior anterior portion of the scapula (hence: coracoid, or “like a raven’s beak”). Pointing laterally forward, it, together with the acromion, serves to stabilize the shoulder joint.

What is trapezoid ligament?

The trapezoid ligament is a broad quadrilateral ligament that is quite thin. It is the anterolateral part of the coracoclavicular ligament. The trapezoid ligament arises from the upper surface of the coracoid process. It attaches to the trapezoid line (or ridge) on the inferior surface of the clavicle.

Is the acromion anterior or posterior?

On the anterior side, facing into the body, is a right-angled process called the coracoid process. While at the superior lateral edge of the scapula the glenoid cavity, which serves as the socket for the head of the humerus bone. The glenoid cavity always points laterally, while the spine and acromion are posterior.

Where is acromion process?

The acromion (plural: acromia), also known as the acromial process, is a small projection of the scapula that extends anteriorly from the spine of the scapula.
