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.
The irregularity of the HPV incubation period is challenging. People exposed to the virus might need to wait for several years before knowing they are or arenât contagious.Alternately, when patients show signs of one of these viruses, they may have no way of knowing when they contracted it.hese symptoms are usually either warts on the genitals or abnormal cancer-causing skin growths on the penis or cervical region. It is difficult to determine a precise incubation period because this varies significantly, even among the same virus types.
