Where is scapula located?
shoulder blade
The scapula is a flat, triangular-shaped bone (colloquially as the “shoulder blade”). It is located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint.
What is the anatomical position of the clavicle?
The clavicle, also referred to as the collar bone, is an elongated, S-shaped bone that sits between the shoulder and sternum at the top of the ribcage. It provides structural support between the shoulder and the rest of the skeleton, and is one of the most frequently fractured bones in the body.
What is a clavicle muscle?
The clavicle is an S-shaped bone that is anchored by strong ligamentous attachments on both its medial and lateral ends. Muscular attachments to the clavicle include the sternocleidomastoid, pectoralis major, and subclavius muscles proximally and the deltoid and trapezius muscles distally.
Should clavicles be horizontal?
The clavicle is the only long bone in the body that lies horizontally. Together with the shoulder blade, it makes up the shoulder girdle.
What is the costal surface of scapula?
The front of the scapula (also known as the costal or ventral surface) has a broad concavity called the subscapular fossa, to which the subscapularis muscle attaches. The costal surface superior of the scapula is the origin of 1st digitation for the serratus anterior origin.
Where is the greater tubercle?
humerus
The greater tuberosity is the prominent area of bone at the top of the humerus and is the attachment for the two large, powerful rotator cuff muscles – supraspinatus and infraspinatus. It is injured/fractured in a fall by either landing directly onto the side of your shoulder or landing with your arm outstretched.
Is clavicle axial or appendicular?
The appendicular skeleton is everything else. It’s everything that attaches on to the axial skeleton. Think “appendages”. The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.
Is the clavicle part of the upper extremity?
The upper limbs or upper extremities are the forelimbs of an upright-postured tetrapod vertebrate, extending from the scapulae and clavicles down to and including the digits, including all the musculatures and ligaments involved with the shoulder, elbow, wrist and knuckle joints.
What are the features of clavicle?
The clavicle is a sigmoid-shaped long bone with a convex surface along its medial end when observed from cephalad position. It serves as a connection between the axial and appendicular skeleton in conjunction with the scapula, and each of these structures forms the pectoral girdle.
Why do I have V shaped collar bones?
Sometimes the pecs, which attach more to the medial part of the clavicles, seem like they are overly tight and short. Sometimes, it feels like the upper traps are pulling on the top, lateral edge of the clavicles, creating a V shape. I call this Vee-ing of the clavicles.
