Anatomy Bones Shoulder

Anatomy 101: Shoulder Bones

There are five major bones in the shoulder. The shoulder bones can easily be affected by falls or accidents, in addition to arthritis. Here is an overview of the shoulder bones:

  1. Scapula: Another name for this bone is the shoulder blade. There are 17 muscles that attach to the scapula! Much of your shoulder motion is between the scapula and the chest. The scapula is part of the “shoulder girdle” which also includes muscle and ligament that allow your shoulder to move.
  2. Clavicle: This bone is also referred to as the collar bone. The clavicle connects the arm to the chest. It has joints on both ends, which can become arthritic.
  3. Acromion: This bone is a flat projection of the scapula that gives the shoulder its square shape.
  4. Coracoid Process: This bone is also a projection of the scapula. It points outward toward the front of the body. This bone is important because its muscles and ligaments help support the clavicle, shoulder joint and humerus.
  5. Glenoid Cavity: This is the socket portion of the ball-and-socket joint of the shoulder. Any abnormalities in the cavity can cause joint instability, which can lead to a condition called “frozen shoulder.”

Bicep Tendon Tear Elbow Shoulder Tendons

A Detailed Guide About Bicep Tendon Tears

Guest post from BicepTendonTear.com

A bicep tendon is a band of fibrous tissues which has the property of being tough as well as flexible. It can withstand tension due to its flexibility. A bicep tendon tear can occur at two places, either at the elbow or at the shoulder. Bicep tear occurring at the shoulder is more common. 90% of the tears happen at the shoulder. Main reasons being over-head weight lifting, not warming up properly before any heavy physical activity, smoking too much, and age. Use of steroids is harmful as well; they lead to various disorders such as deficiency in sperm count, impotency and infertility. Moreover, they may lead to dysplasia of collagen fibrils, which can decrease the tensile strength of tendon, thus causing the bicep tendon to tear. These tears weaken your arm to an extent that 30% of your flexural strength and 40% of your supination strength decreases.

Hand Rotator Cuff Shoulder Shoulder Pain

5 Potential Causes of Shoulder Pain

Shoulder pain can be caused by a wide variety of issues. This is because the shoulder is comprised of several key structures, including tendons, cartilage and bone. The shoulder itself is a ball-and-socket joint, which allows a wide range of movement.

Shoulder pain can range from pain simply with moving the shoulder to the inability to lift the arm overhead or feeling weak. Here are five potential causes of such shoulder pain:

  1. Shoulder Arthritis: This can be caused by everyday wear and tear.
  2. Frozen Shoulder: If you have frozen shoulder, the inner lining of your shoulder has become inflamed and tight, preventing you from having full motion and also causing pain.
  3. Shoulder Dislocation: A dislocation is when the ball slides out of the socket. This is most commonly caused by an athletic injury or fall.
  4.  Shoulder Fractures: A shoulder fracture is another word for a broken shoulder. It can be a break of the ball, socket or scapula.
  5. Rotator Cuff Injuries: The rotator cuff is where the four tendons that encompass the ball of the shoulder meet. Injuries to the rotator cuff can cause shoulder pain.

Anatomy Brachial Plexus Nerves Shoulder

Anatomy 101: Brachial Plexus

brachial-plexus

The brachial plexus is a group of nerves that stem from the spinal cord in the neck and travel all the way down the arm. These nerves control the muscles of the shoulder, elbow, wrist and hand. They also provide feeling in the arm.

It starts with the five “roots” at the neck. The second level is called “trunks,” which continue toward the shoulder then divide into the third layer of two nerves called the anterior division and the posterior division. The nerves in the fourth layer are called “cords,” and the final layer is comprised of the “branches” that feed the shoulder and arm. See the image below for details.

Some of the most common injuries in yoga are muscle or joint problems, though most problems are mild. Yoga can even be a safe and helpful form of exercise for people with joint issues like rheumatoid arthritis, as long as you know how to modify postures with the help of your yoga teacher.

Here are seven tips to help keep your joints healthy and safe in yoga:

1. Protect your wrists: Spread your hands wide and evenly when your hands bear weight, such as in Downward Facing Dog Pose.

Beginners in yoga often tent their hands in Downward Facing Dog Pose, but this actually makes it more difficult on your hands and wrists. Make sure that your hands are spread wide and ground all corners of your palm on your mat. Your hands should be pressed down firmly enough that someone would not be able to pluck your fingers off the mat.

Dr. David Wei of Orthopaedic & Neurosurgery Specialists in Greenwich, CT, an orthopedic hand surgeon who specializes in injuries of the hand, wrist, and elbow, explains:
