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 incubation period for HPV is weeks or months. Human papillomavirus lives on the skin. Cancer can form only in advanced stages and not in every case. The disease can be transmitted from person to person even when the infected person doesn't have any signs of human papillomavirus.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.
