There are flat bones in the skull occipital parietal frontal nasal lacrimal and vomer the thoracic cage sternum and ribs and the pelvis ilium ischium and pubis. It joins the humerus upper arm bone with the clavicle collarbone.
The function of flat bones is to protect internal organs such as the brain heart and pelvic organs.
Is the clavicle a flat bone. Flat bones are composed of two compact surfaces with a spongy bone layer in the middle. The clavicle bone also called the collarbone is a flat bone which attaches on one end to the sternum or breastbone and on the other end to the scapula or shoulder blade. The clavicle is a long bone of the body not a flat bone.
The clavicle is the collarbone which is located in the upper part of the chest just under. The scapula which is commonly known as the shoulder blade is a triangular-shaped bone that forms the posterior section of the shoulder girdle. It joins the humerus upper arm bone with the clavicle collarbone.
It is a flat paired bone with an extensive surface for muscular attachment. In this regard is the clavicle a irregular bone. The major bones of the arms humerus radius and ulna and the legs the femur tibia and fibula are all long bones.
The flat bones include the scapula wingbone the ribs and the sternum breastbone. Flat Bones Protect Internal Organs. There are flat bones in the skull occipital parietal frontal nasal lacrimal and vomer the thoracic cage sternum and ribs and the pelvis ilium ischium and pubis.
The function of flat bones is to protect internal organs such as the brain heart and pelvic organs. Flat bones are a specific type of bone found throughout your body. Well go over all the flat bones in your body from your head to your pelvis.
Youll also learn about the internal structure. -articulates with the clavicle and the humerus-is a flat bone covering the posterior regions of ribs 5-10-has a superior angle that forms the high point of the shoulder-all of these choices. The entire tibia bone would be considered a tissue.
If a patient has sinusitis with pain superior to the bridge of the nose the sinus that is involved is likely the sphenoid bone. False the sphenoid bone is BEHIND the eyes. HIgher is above the cheeks is maxillary–or between the eyes are ethmoid.
It appears as a small flattened oval surface and enables the clavicle to articulate about the acromion of the scapula in the acromioclavicular joint. In contrast the inferior surface of the clavicle is quite rough and has many prominent lines indicating sites where muscle and ligaments may attach to the bone. Some flat bones contain irregular structures.
For example the scapula bone is a flat bone but it contains a spine acromion and coracoid process that make it appear somewhat irregular. There are 36 flat bones in the adult skeleton including some skull bones as well as the sternum and ribs. The clavicle collarbone extends between the manubrium of the sternum and the acromion of the scapula.
It is classed as a long bone and can be palpated along its length. In thin individuals it is visible under the skin. The clavicle also called the collar bone connects the shoulder to the sternum.
A small lump over the clavicle may be caused by a tumor formed from fatty tissue. The lump can usually be moved with slight pressure and is not painful. 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. The clavicle is a long bone. It supports the shoulder so that the arm can swing clearly away from the trunk.
The clavicle transmits the weight of the limb to the sternum. The bone has a cylindrical part called the shaft and two ends lateral and medial. The shoulder is the most mobile joint in the human body.
However the extreme range of its potential movements makes the shoulder joint. Reviewed by Medical team 2021-06-20. The clavicle more commonly known as the collar bone is a type of flat bone.
One end of the collar bone forms a joint with the sternum the breastbone while the other end forms a joint with the scapula or the shoulder blade. The scapula or shoulder blade is a flat triangular bone located to the posterior of the shoulder. The scapula articulates with the clavicle through the acromion process a large projection located superiorly on the scapula forming the acromioclavicular joint.
The scapula also articulates with the humerus of the upper arm to form the shoulder. The clavicle or collarbone is broken most frequently in fallsfrom bikes while skiing and when doing other sports. A twisted thin flat bone the clavicle presents lots of problems for surgeons trying to fix fractures.
Here are some of the pitfalls. The clavicle acts as a strut reaching from the sternum to the scapular of the shoulder. Specifically it connects the arm bone the humerus with the collar bone the clavicle.
The scapula is a flat bone so it has a large area for muscle attachment. There are 18 muscles that are attached to various parts of the scapula either by insertion or by origin points. The human clavicle is the only bone of the shoulder girdle forming a synovial joint with the trunk.
The bone is connected strongly to a number of muscles and accordingly to fascies. Acromion has a relatively flat superior and inferior surface a shape compatible with pull from muscles and ligaments. 0 1979 Munksgaard Copenhagen.
