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 was an ideal accompaniment for voice and other soft instruments, and the most eloquent of all solo instruments. In paintings and other art works the lute is often associated with Apollo, angels, or Orpheus, and it is often mentioned at climactic points in tragedies. On the other hand, the lute also played a prominent role in comedy.
