For most individuals, back pain is self-limiting. Most people with back pain do not experience chronic severe pain but rather persistent or intermittent pain that is mild or moderate. [7] In most cases of herniated disks and stenosis, rest, injections or surgery have similar general pain-resolution outcomes on average after one year.
This plastoquinol is later oxidized back to PQ, releasing the 2e-to the cytochrome b 6 f complex and the two H + ions into the thylakoid lumen. The electrons then pass through Cyt b 6 and Cyt f to plastocyanin , using energy from photosystem I to pump hydrogen ions (H + ) into the thylakoid space.
Bone pain belongs to the class of deep somatic pain, often experienced as a dull pain that cannot be localized accurately by the patient. This is in contrast with the pain which is mediated by superficial receptors in, e.g., the skin. Bone pain can have several possible causes ranging from extensive physical stress to serious diseases such as ...
Low back pain is not a specific disease but rather a complaint that may be caused by a large number of underlying problems of varying levels of seriousness. [30] The majority of low back pain does not have a clear cause [1] but is believed to be the result of non-serious muscle or skeletal issues such as sprains or strains. [31]
Human anatomy of the back. Back injuries result from damage, wear, or trauma to the bones, muscles, or other tissues of the back. Common back injuries include sprains and strains, herniated discs, and fractured vertebrae. [1] The lumbar spine is often the site of back pain.
Photosynthesis usually refers to oxygenic photosynthesis, a process that produces oxygen. Photosynthetic organisms store the chemical energy so produced within intracellular organic compounds (compounds containing carbon) like sugars, glycogen , cellulose and starches .
The following is an alphabetical list of Greek and Latin roots, stems, and prefixes commonly used in the English language from P to Z. See also the lists from A to G and from H to O.
Due to back strain, the tendons and muscles supporting the spine are twisted or pulled. Chronic back strain occurs because of the sustained trauma and wearing out of the back muscles. [1] Acute back strain can occur following a single instance of over stressing of back muscles, as in lifting a heavy object.
