Transverse ligament of atlas former is attached to the basilar part of the occipital bone, in close relation with the membrana tectoria; the latter is fixed to the posterior surface of the body of the axis; hence, the whole ligament is named the cruciate ligament of the atlas. The transverse ligament divides the ring of the atlas into two unequal parts: of these, the posterior and larger serves for the transmission of the medulla spinalis and its membranes and the accessory nerves; the anterior and smaller contains the odontoid process. The neck of the odontoid process is constricted where it is embraced posteriorly by
Coenurosis in humans the oncospheres develop into cystic like larvae balls called coenuri. The cycle perpetuates when a canid (definitive host) ingests the tissue of an infected intermediate host. When this happens, the maturing larvae reside in the small intestine of the definitive host until they mature into adult worms and begin producing eggs (which will eventually be passed through feces into the environment once again). Because this disease is so rare in humans, accurate diagnostic techniques have not been developed. CT scans and MRI’s are useful for detecting fluid filled cysts in all areas of the body, and some serological and microscopic
