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 is an instrument with a long history and has been found throughout the Eastern Hemisphere. Lute-like instruments were played in Mesopotamia as early as 2000 B.C. and in Egypt as early as 1500 B.C. But it did not find its way to Europe until after A.D. 900.
