  4. pronucleus(English)

    • both the sperm and egg pronuclei are encased in a nuclear membrane. The male pronucleus is associated with the sperm centrosome, whose centrioles organize an aster (a starlike microtubular structure), which slowly drives the male pronucleus from its cortical position toward the egg pronucleus until they meet and fuse around the middle of the egg. However, the female pronucleus is not a passive partner; it also goes the “extra mile” to meet the male partner by moving along microtubules of the sperm aster. In species in which the egg centrosome disintegrates and is absorbed, the male centrosome serves as the only organizing center of the egg for building the cytoskeleton, which drives the sperm pronucleus in the direction of the egg pronucleus toward their fusion. On their way to the middle of the egg, both pronuclei replicate their decondensed DNA

  5. phrenic nerve(English)

    • derived from motor neurons and corresponding nerve roots of C3–C5, innervates half of the diaphragm. Dysfunction of one or both phrenic nerves can result from direct nerve trauma, cervical spinal cord pathology, or various types of neuromuscular diseases. In addition to the clinical physical examination, diagnostic tests to assess phrenic nerve function include chest X-ray, chest fluoroscopy, pulmonary function tests, phrenic nerve conduction studies, and needle electromyography of the diaphragm
