Small nerves might comprise a single funiculus, but in case of large nerves, the funiculi join to form large bundles of nerve fibers called fasciculi. These are kept together by membranous sheaths or layers of connective tissue called endoneurium, perineurium, and epineurium. The epineurium is a sense layer of connective tissue that envelops the entire nerve trunk. It surrounds the fascicles and the blood vessels that supply the nerve.
1 The latent period between infection with a cancer-causing HPV virus and demonstration of Pap smear abnormalities can be measured in years. 2  Once dysplastic changes are initiated, the degree of dysplasia typically slowly worsens as the cellular changes progress toward cancer.
History. See the list below: The incubation period of Hantavirus pulmonary syndrome (HPS) ranges from 1-4 weeks. HPS has been divided into 3 clinical phases: (1) the prodromal phase, (2) the cardiopulmonary phase, and (3) the convalescent phase.1  Prodromal symptoms resemble those of many viral illnesses, including fever, headache, and myalgias.istory.
