Coracobrachialis muscle

The biceps brachii, often just called the biceps, is one of the better-known muscles in the body, thanks to its bulging appearance when you flex your upper arm as well as exercises named for causing that bulge, such as biceps curls. This muscle runs from two connecting points at the shoulder down to your elbow. Doctors tap the bicep tendon to test reflexes of the C6 spinal cord segment via the musculocutaneous nerve. The coracobrachialis lies inside your upper arm just below the biceps. It also runs from the shoulder to the elbow. It helps flex your arm at the shoulder and plays a minor role in pulling the arm in toward your body. Associated Conditions The musculocutaneous nerve isn’t injured often because it’s well protected in the axilla (near the shoulder and armpit) and elsewhere along its course through the arm. Most often, musculocutaneous nerve dysfunction is caused by injury to the brachial plexus, which contains numerous nerves. • Demircay E, Musluman AM, Cansever T, et al.

• 1 Overview • 2 Anatomical Course • 3 Motor Functions • 4 Sensory Functions • 5 Clinical Relevance: Injury to the Musculocutaneous Nerve The musculocutaneous nerve is a major peripheral nerve of the upper limb. In this article, we shall look at the anatomy of the musculocutaneous nerve – its anatomical course, motor and sensory functions, and its clinical correlations. Anatomical Course The musculocutaneous nerve is the terminal branch of the lateral cord of the It leaves the coracobrachialis muscle near its point of insertion on the The nerve then pierces the deep fascia lateral to biceps brachii to emerge lateral to the biceps tendon and brachioradialis. It continues into the forearm as the lateral cutaneous nerve and provides sensory innervation to the lateral aspect of the forearm. Note: The musculocutaneous nerve is well recognised to have a varied anatomical course. It can interact with the median nerve, adhering to the nerve and exchanging fibres. Alternatively, it may pass under the coracobrachialis instead of through it, and/or through the biceps brachii. Motor Functions The musculocutaneous nerve innervates the muscles in the • Biceps brachii • Brachialis • Coracobrachialis These muscles flex the upper arm at the shoulder and the elbow. In addition, the biceps brachii also supinates the forearm. A useful mnemonic to help you remember these muscles is BBC. Sensory Functions The musculocutaneous nerve gives rise to the lateral cutaneous nerve of forearm. This nerv...

Coracobrachialis Muscle Pain & Trigger Points The coracobrachialis muscle can trigger pain at the front of your shoulder as well as at the back of your upper arm and forearm. People that suffer from tightness, tender or trigger points in this muscle, usually also have problems with its synergists. Those are the pectoralis major, the front part of the deltoid and the short head of the biceps brachii. 1.1 Pain patterns If your coracobrachialis harbors trigger points, it can give you pain right at their location and send it to other, seemingly unrelated areas of your body. In the pictures you can see that trigger points in the coracobrachialis can trigger pain that radiates down the backside of your arm to the back of your hand. It might also be possible that you feel an ache at the side of your shoulder. Less often the back of your shoulder will be painful. It can be involved in the following symptoms. • Pain in front of shoulder 4. Trigger Point Activation of the Coracobrachialis Muscle It is known that the coracobrachialis is overloaded especially with actions that also overwork the synergistic muscles that are listed above. Trigger and tend...

Function [ ] The coracobrachialis is functionally insignificant. It is a weak It additionally also resists deviation of the arm from the frontal plane during abduction. Clinical significance [ ] The overuse of the coracobrachialis can lead to stiffening of the muscle. Common causes of injury include chest workouts or activities that require one to press the arm very tight towards the body, e.g. work on the rings in gymnastics. Symptoms of overuse or injury are pain in the arm and shoulder, radiating down to the back of the hand.

MUSCLE OF THE DAY: “Coracobrachialis” Show Up Fitness - Where Great Trainers Are Made Learn more about becoming a personal trainer HERE. The coracobrachialis is a long and slender muscle located in the anterior compartment of the arm along with the biceps brachii and brachialis. The prefix coraco- comes from the Greek corax meaning “raven or crow.” The ancient anatomist Galen, when analyzing the anterior projection of the scapula (coracoid process), saw that it resembled a crow perched on a branch. Brachialis derives from the Latin brachium, meaning “arm.” Origin(s) (proximal attachment): Coracoid process of the scapula. Insertion(s) (distal attachment): Anteromedial surface of the humeral shaft. Action(s): Adduction and flexion of the arm at the glenohumeral joint. Also, when the arm is abducted and extended, the coracobrachialis acts as a strong antagonist to the deltoid. Common Injuries to the Coracobrachialis: Common Injuries to Coracobrachialis: Coracobrachialis is susceptible to over-use and over-training due its function of flexing and adducting the arm. This will lead to tightening, shortening and the development of trigger points. Trigger points are defined as discrete, focal, hyperirritable spots located in a tight band of skeletal muscle. Ouch! Symptoms commonly include pain through the arm and shoulder, and in some cases down through the forearm into the back of the hand. In other cases, the musculocutaneous nerve can become trapped causing arm weakness and ner...
