In a selective nerve root block, a small needle is placed in the foramen alongside the nerve root and the medication is injected. When the nerves in the foramina are irritated or pinched by a bulging disk, narrowed ânerve canalâ or bone spur, the resulting inflammation can cause pain, numbness, or tingling.
The corpus luteum (Latin for yellow body; plural corpora lutea) is a temporary endocrine structure in female mammals that is involved in the production of relatively high levels of progesterone and moderate levels of estradiol and inhibin A.
The lute derives its name, as well as its distinctive shape, from the Arabic 'ud, an instrument which is vey much at the heart of Arabic musical life to this day. 'Al 'ud' means 'the wooden one', a name perhaps coined to distinguish the 'ud from instruments made from gourds or with parchment soundboards.
