What is scapula diagram?
The scapula is also known as the shoulder blade. It articulates with the humerus at the glenohumeral joint, and with the clavicle at the acromioclavicular joint. In doing so, the scapula connects the upper limb to the trunk.
What is your scapula?
The scapula, or shoulder blade, is a large triangular-shaped bone that lies in the upper back. The bone is surrounded and supported by a complex system of muscles that work together to help you move your arm.
How many bones are in scapula?
The shoulder is made up of three bones: the scapula (shoulder blade), clavicle (collarbone) and humerus (upper arm bone). Two joints in the shoulder allow it to move: the acromioclavicular joint, where the highest point of the scapula (acromion) meets the clavicle, and the glenohumeral joint.
Which are parts of the scapula?
The scapula has three processes: the acromion, the spine, and the coracoid process. Muscle attachments to these landmarks are covered in the “Muscles” section. The ventral surface of the scapula abuts the thoracic rib cage and has a large concavity called the subscapular fossa where the subscapularis attaches.
What organ does the scapula protect?
The scapula stabilizes the arm and neck This bone is located posteriorly (on the back half of the body). The scapula plays an important role in stabilizing the other bones involved in the rhythm of shoulder motion.
How do you find the scapula?
Scapula, also called shoulder blade, either of two large bones of the shoulder girdle in vertebrates. In humans they are triangular and lie on the upper back between the levels of the second and eighth ribs.
What is the main function of scapula?
The scapula is an important bone in the function of the shoulder joint. It engages in 6 types of motion, which allow for full-functional upper extremity movement including protraction, retraction, elevation, depression, upward rotation, and downward rotation.
How do you find the side of your scapula?
Left–In order to determine if a scapula is right or left, orient it so the glenoid cavity (articulating surface) faces laterally (outward) and the spine is posterior (toward back) and superior (upper). The coracoid process should be anterior and superior.
What type of bone is scapula?
Flat bones: Flat bones are thin and have broad surfaces. The flat bones include the scapula (wingbone), the ribs, and the sternum (breastbone).
How do you relieve scapular pain?
Relieving the Pain Under Your Shoulder Blade
- Rest your upper back from activity. If your pain worsens when you do certain movements or physical activities, such as household chores or exercise, rest for a day or two.
- Apply ice and/or heat.
- Take over-the-counter (OTC) medication.
- Massage it out.
- Visit a health care provider.
What kind of bone is the scapula?
The scapula is a large, flat triangular bone with three processes called the acromion, spine and coracoid process . It forms the back portion of the shoulder girdle. The spine (which is located at the back of the scapula) and the acromion can be readily palpated on a patient.
What are the movements of the scapula?
The movements of the scapula are protraction, retraction, depression, elevation, upward rotation, and downward rotation.
What does the scapula do?
The primary function of the scapula is to attach the upper arm to the thorax, or trunk of the body.
What muscles form the scapula?
The scapula is a wide, flat bone lying on the thoracic wall that provides an attachment for three groups of muscles: intrinsic, extrinsic, and stabilising and rotating muscles. The intrinsic muscles of the scapula include the muscles of the rotator cuff—the subscapularis, teres minor, supraspinatus, and infraspinatus.
How many muscles attach to the scapula?
There is a total of 17 muscles connected to the scapula, 11 of which originate from it, whereas 6 others have it as a point of insertion.
