Where is the distal end of clavicle located?
It is located above the first rib, and it articulates with the sternal manubrium proximally (sternoclavicular joint) and the acromion distally (acromioclavicular joint) (Gray, 1918).
What is the sternal end of clavicle?
The orientation of the clavicle can be distinguished by its ends: a broad, flat acromial end (referred to as the lateral third); and a round pyramidal-like sternal end (referred to as the medial two-thirds). Each end has unique bony landmarks, depending whether the superior or inferior surface of the bone is viewed.
Is the shoulder lateral to the collarbone?
The clavicle (collarbone) is an S-shaped bone located on the anterior side of the shoulder. It is attached on its medial end to the sternum of the thoracic cage, which is part of the axial skeleton. The lateral end of the clavicle articulates (joins) with the scapula just above the shoulder joint.
Is collarbone and clavicle the same?
Your collarbone (or clavicle) is the bone that runs horizontally between the top of your breastbone (sternum ) and shoulder blade (scapula). You can feel your collarbone by touching the area between your neck and your shoulder. A broken collarbone, also called a clavicle fracture, is when this bone breaks.
Is the clavicle part of the trunk or neck?
The clavicle is the only bony attachment between the trunk and the upper limb. It forms the front portion of the shoulder girdle and is palpable along its entire length with a gentle S-shaped contour. The clavicle articulates at one end with the sternum (chest bone) and with the acromion of the scapula at the other.
Is the clavicle part of the scapula?
The scapula is a much more complicated bone. The flat part, or blade, is roughly triangular with an upper border, a lateral border, and a medial border. The bones that connect the upper extremity to the trunk are the clavicle, or collar bone, and the scapula, or shoulder blade.
What are the two ends of the clavicle?
It can be divided into three parts: medial end, lateral end, and shaft.
- Medial end. The medial end is also known as the sternal end.
- Lateral end. The lateral end is also known as the acromial end.
- Collarbone fracture.
- In dinosaurs.
Where is the sternal end?
The sternal end (sternal extremity) of the clavicle is triangular in form, directed medialward, and a little downward and forward; it presents an articular facet, concave from before backward, convex from above downward, which articulates with the manubrium sterni through the intervention of an articular disk.
What holds the clavicle in place?
Ligaments attach the bones together to hold the AC joint together. One set of ligaments surrounds the joint to form the joint capsule, and two other sets of ligaments hold the collarbone down by attaching to the bony knob on the top of your shoulder blade, which is called the coracoid process.
What attaches to the clavicle?
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.
Is the collarbone on the left or right side?
The clavicle or collarbone is a long bone that serves as a strut between the shoulder blade and the sternum or breastbone. There are two clavicles, one on the left and one on the right.
Where does the name of the collarbone come from?
Last Updated: Oct 9, 2017. The clavicles, or collarbones, are a pair of long bones that connect the scapula to the sternum. The name clavicle comes from the Latin word for “little key” and describes the shape of the clavicle as an old-fashioned skeleton key. The clavicle is one of the most commonly broken bones in the human body.
How is the collarbone connected to the shoulder blade?
The collarbone connects the breastbone to the shoulder blade. A broken collarbone is a common injury that causes pain and swelling at the site of the fracture. A broken collarbone is a common injury, particularly in children and young adults. Your collarbone connects the upper part of your breastbone to your shoulder blade.
What happens to the bone after a broken collarbone?
A severely broken collarbone might heal slowly or incompletely. Poor union of the bones during healing can shorten the bone. A lump in the bone. As part of the healing process, the place where the bone knits together forms a bony lump. This lump is easy to see because it’s close to the skin. Most lumps disappear over time, but some are permanent.
