What is a Deltoid Muscle? It is the most superficial muscle of the shoulder joint, therefore, it defines the round contour of our shoulders. Deltoid has associated muscles that move and help in our overall movement of shoulders. Having the shape of the symbol delta, i.e. triangular, this muscle is termed as Musculus deltoideus in Latin. A deltoid muscle has three parts, namely- • Clavicular Part of Deltoid Muscle: It is also known as Musculus deltoideus pars clavicularis in Latin. It originates from the lateral third of the clavicle. • Acromial Part of Deltoid Muscle: Also known as Musculus deltoideus pars acromialis in Latin, it originates from the acromial of the scapula (posterior). • Spinal Part of Deltoid Muscle: Also known as the musculus deltoideus pars spinalis in Latin, it originates from the spine of the scapula. All of these three points converge towards the insertion point called deltoid tuberosity, found on the lateral surface of the shaft of the humerus. Innervation: In order for the deltoid muscles to carry out all the movements, it requires a nerve to instruct when to do and when, this muscle is thus innervated by an axillary nerve called Nervus axillaris in Latin. This axillary nerve carries fibres from the C5 and C6 nerve roots of the brachial plexus. [Image to be added Soon] What is the Function of Deltoid Muscle? It’s an obvious question to arise and knowing its location and function of the deltoid muscles will help us understand its necessity. • It hel...

Overview The deltoid is a round muscle that goes around the top of your upper arm and shoulder. The main function of the deltoid is to help you lift and rotate your arm. There are three parts of the deltoid muscle that connect your collarbone, shoulder, and shoulder blade to your upper arm. The three parts are referred to as the anterior, middle, and back. Read on to learn more about what to expect from deltoid pain and how it’s treated. You’ll usually feel deltoid pain or soreness in your shoulder. Symptoms vary depending on the severity of the strain. Deltoid strains are classified in three grades. Grade one If you have a grade one strain, you can use your arm normally, but will have some tightness or soreness in your shoulder. Your shoulder may be slightly swollen. Grade two Grade two strains are partial deltoid muscle tears. With a grade two strain, you will have trouble using or lifting your arm normally. You may have sudden pain while trying to use your arm, and your shoulder will be moderately swollen. Grade three Grade three strains are more severe or complete deltoid muscle tears. Muscle tears can lead to severe pain and an inability to move your arm normally, or at all. Your shoulder will be very swollen. Deltoid pain is usually caused by overusing your deltoid muscle without rest or proper warm-up. This increases your risk for a muscle Deltoid pain is more common in people who do a lot of strenuous exercise involving the shoulder, such as: • weight lifting • swi...

You likely don’t think much about the deltoid muscles — or perhaps don't even know what they are. But if you’ve ever had a goal of The deltoid is a large muscle that covers the top of each shoulder joint. The deltoids are comprised of three parts: the anterior, middle and posterior deltoid. These fibers cover the upper arms to provide the round shape we’re accustomed to. But beyond aesthetics, the deltoid muscle also protects the shoulder joint, preventing injuries, and Dumbbell shoulder press Stand with feet hip-distance apart. Hold a dumbbell in each hand.

Your pecs help raise your chest and ribs during forced respiration or heavy breathing. The elevation is necessary for your lungs to fully expand as you take in and breathe out air. Associated Conditions While rare, a pectoralis major rupture can happen if the amount of force applied to the muscle overloads the tendon and causes it to tear. Healing from a pectoralis major rupture is different for everyone. Check with your healthcare provider and physical therapist before starting any exercises or stretches for your pec injury. If a pinched nerve is causing your pectoralis major weakness, the first step is to take the pressure off the nerve. Pinched nerves usually come from your spine, often as the result of a • Merolla G, Paladini P, Campi F, Porcellini G.

The biceps is a large muscle situated on the front of the upper arm between the shoulder and the elbow. Also known by the Latin name biceps brachii (meaning "two-headed muscle of the arm"), the muscle's primary function is to flex the elbow and rotate the forearm. The heads of the muscle arise from the • Biceps strains occur when the muscle is overstretched or "pulled," causing some of the muscle fibers or tendons to tear. Sudden pain and swelling are common. • Partial tendon tears involving either the proximal tendon near the shoulder or the distal tendon near the elbow are characterized by pain, swelling, and an odd bulge at the site of the injury. In addition to physical trauma, the degeneration of the tendon due to age or repetitive use can cause partial tears. • Complete tendon tears occur when a An abnormal bulge known as a "Popeye deformity" will sometimes develop, caused when the tendon recoils from its incision point like a rubber band. • Insertional tendonitis is the inflammation of the tendon at the site where it connects with bone. It may be caused by a sudden increase in physical activity or the repetitive flexure or supination of the joint (such as twisting a screwdriver). Joint pain, • Rest to protect the injured shoulder, arm, or elbow • Ice application, using an ice pack three or more times per day for 10 to 20 minutes to reduce swelling • Compression, using an elastic bandage to decrease swelling and help immobilize the injured shoulder or elbow • Elevati...

Anterior Deltoid: Functional Anatomy Guide The anterior deltoid (L. anterior, before, in front of ; deltoides, triangular) refers to the front head of the deltoid muscle. In this post you will find out everything you need to know about your anterior deltoid functional anatomy – shape (appearance), function (muscle action), location, insertion, and origin. Introduction Your shoulder muscles are called deltoids, or delts in gym jargon. The deltoids are two interesting muscles whose name means “triangular in outline”. There is one deltoid muscle in each of your shoulders. Muscles of the anterior shoulder region The main shoulder muscle, the deltoid, is divided into three areas, or heads. Anatomical and functional segments of the deltoid muscle: • the anterior (front) deltoid; • the lateral (side) deltoid; • the posterior (rear) deltoid; This three-part muscle wraps around the cap of the shoulder joint. Other Names for Anterior Deltoid • Front Deltoid • Anterior head of the deltoid • Front of the shoulder • Front Delts Anterior Deltoid: Location, Function, Origin, Insertion The anterior division, also known as the anterior deltoid, is located on the front of your shoulder just above the chest muscles. More precisely, it is situated medial to the lateral deltoid and lateral to the clavicular head of the pectoralis major. When you get lean enough, you’ll be able to see all three heads contracting while you train. As you can see from the image above, deltoid muscle (and all its t...
