Where does suprascapular artery branch of from?
subclavian artery
The suprascapular artery supplies the supra- and infraspinatus muscles and travels with the suprascapular nerve. It is a direct branch from the subclavian artery (12%), the thyrocervical trunk (27%) or the internal thoracic artery (11%).
What does the suprascapular artery come off of?
The suprascapular artery is a branch of the thyrocervical trunk, which emerges from the first part of the subclavian artery. It runs across the front of your neck and behind the clavicle (collarbone) to supply blood to the muscles, skin, and bones in your chest and shoulder.
What are the branches of suprascapular artery?
Subscapular artery
| Origin | Axillary artery |
|---|---|
| Branches | Thoracodorsal artery, circumflex scapular artery |
| Supply | Deltoid muscle, latissimus dorsi muscle, long head of triceps brachii muscle, subscapularis muscle, supraspinatus muscle, infraspĪ¹natus muscle, serratus anterior muscle, adjacent skin |
Can you palpate the suprascapular notch?
Occasionally, the suprascapular notch may be tender to palpation. Weakness involves shoulder abduction (supraspinatus) and external rotation (infraspinatus). Impairment of these motions may or may not be noticed by the patient, because both functions are subserved by other muscles as well.
What artery supplies the infraspinatus?
The infraspinatus is supplied arterially by the suprascapular and circumflex scapular arteries. The suprascapular artery either originates from the thyrocervical trunk or the subclavian artery.
What artery runs through your shoulder?
The brachial artery is the largest artery serving the shoulder and arm. It travels down the upper arm and through the elbow before dividing into the radial and ulnar arteries below the elbow. In the shoulder, branches of the brachial artery provide oxygenated blood to the muscles and bones.
What artery supplies the subscapularis?
Posterior circumflex humeral artery supplying the subscapularis muscle.
Is Suprascapula a bone?
Anatomical terms of bone The suprascapular notch (or scapular notch) is a notch in the superior border of the scapula, just medial to the base of the coracoid process. It forms the entrance site into the suprascapular canal.
What does suprascapular mean?
medical Definition of suprascapular notch. : a deep notch in the upper border of the scapula at the base of the coracoid process giving passage to the suprascapular nerve.
What does posterior cruciate ligament mean?
Posterior cruciate ligament. The posterior cruciate ligament is one of the four major ligaments of the knee. It connects the posterior intercondylar area of the tibia to the medial condyle of the femur. This configuration allows the PCL to resist forces pushing the tibia posteriorly relative to the femur.
What is a popliteal ligament?
The popliteal ligament is one of two ligaments found in the leg behind the knee joint. Both extracapsular ligaments, meaning that they are located to the outside of the joint capsule, the oblique popliteal ligament and arcuate popliteal ligament link the bones of the knee on their posterior sides.
What is a carpal ligament?
Carpal ligaments. Multiple ligaments help stabilize the wrist to the forearm and hand. Extrinsic ligaments span the radiocarpal joint, whereas intrinsic ligaments form connections between individual carpal bones. An important extrinsic ligament on the dorsal aspect of the wrist is the dorsal radiocarpal ligament (see the first image below).
