Curvature
Curvature
Curvature (/kɜːrˈveɪʃər/) is a term used in various branches of medicine to describe the degree to which a biological structure or path deviates from being a straight line, or a plane, in its natural state.
Etymology
The term "curvature" is derived from the Latin word "curvatura", which means "bending" or "curve". It has been used in the English language since the 15th century.
In Medicine
In medicine, curvature is often used to describe the bending of the spine, bones, arteries, or other anatomical structures. Abnormal curvatures can lead to various medical conditions such as scoliosis, kyphosis, and lordosis.
Spinal Curvature
In the context of the spine, curvature refers to the natural curves present in a healthy spine when viewed from the side, and the straight line it forms when viewed from the front or back. Abnormal spinal curvature can lead to conditions such as:
- Scoliosis: A condition characterized by a sideways curvature of the spine.
- Kyphosis: A condition characterized by an excessive outward curvature of the spine, causing hunching of the back.
- Lordosis: A condition characterized by an excessive inward curvature of the spine.
Arterial Curvature
In the context of arteries, curvature refers to the natural bends and turns that arteries make throughout the body. Abnormal arterial curvature can lead to conditions such as atherosclerosis, where the arteries become clogged with plaque.
