What is the ACJ ligament?
The acromio-clavicular joint (ACJ) is where the collarbone meets the shoulder blade. Injuries here are most commonly caused by a fall onto or direct blow to the shoulder. The force causes an injury to the ligaments that surround and stabilise the ACJ.
Where is the ACJ joint?
The acromioclavicular joint is located at the top of the shoulder. Acromioclavicular joint pain is often shortened to ACJ pain or sprain. It is when the joint between the clavicle (collar bone) and the acromion (part of the shoulder blade) becomes inflamed.
What anatomical structures form the AC joint?
The AC Joint is formed by the junction of the lateral clavicle and the acromion process of the scapula and is a gliding, or plane style synovial joint. The AC Joint attaches the scapula to the clavicle and serves as the main articulation that suspends the upper extremity from the trunk.
What is an ACJ injury?
Your acromioclavicular joint (ACJ) is the area where your collarbone meets your shoulder blade. Injuries to this area are most commonly caused by direct impact or through a fall. Symptoms of ACJ injury are pain, swelling and reduced mobility. Mild damage can be treated with rest, ice and anti-inflammatory medication.
What are 3 main ligaments that make up the acromioclavicular joint?
Acromioclavicular (AC) joint
| Type | Synovial plane joint; multiaxial |
|---|---|
| Ligaments | Intrinsic: Superior acromioclavicular ligament, inferior acromioclavicular ligament Extrinsic: Coracoclavicular ligament (with conoid and trapezoid parts) |
| Innervation | Lateral pectoral nerve, suprascapular nerve |
What is ACJ excision?
Arthroscopic Acromio-Clavicular (ACJ) excision is a common procedure undertaken to address the symtoms of shoulder pain. Its most commonly performed along with subacromial decompression of the shoulder. The aim of the operation is to undertake a thorough examination of the shoulder joint and the subacromial space.
What does a positive Hawkins test indicate?
A positive Hawkins-Kennedy test is indicative of an impingement of all structures that are located between the greater tubercle of the humerus and the coracohumeral ligament. The impinged structures include the supraspinatus muscle, teres minor muscle, and the infraspinatus muscle.
How is the lung part of the respiratory system?
Anatomy of the Lung. The lungs are the major organs of the respiratory system, and are divided into sections, or lobes. The right lung has three lobes and is slightly larger than the left lung, which has two lobes. The lungs are separated by the mediastinum. This area contains the heart, trachea, esophagus, and many lymph nodes.
Which is the tube that carries air in and out of the lungs?
The trachea is a tube that carries the air in and out of your lungs. Each lung has a tube called a bronchus that connects to the trachea. The trachea and bronchi airways form an upside-down “Y” in your chest.
Which is larger the left or right lung?
The right lung has three lobes and is slightly larger than the left lung, which has two lobes. The lungs are separated by the mediastinum. This area contains the heart, trachea, esophagus, and many lymph nodes. The lungs are covered by a protective membrane known as the pleura and are separated from the abdominal cavity by the muscular diaphragm.
What are the three lobes of the right lung?
The right lung has three lobes: Upper lobe, Middle lobe, Lower lobe The left lung has two lobes: Upper lobe, Lower lobe The heart sits in the mid chest extending into the left side Oxygen is inhaled and released from the lungs to the blood.
