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 term latent period can also be used when talking about treatment - it is the time interval between the beginning of a therapy and the beginning of response. In short - incubation period = time for develpment = time from getting the bug till getting sick. this is a very active stage for the bug. latent period = a very low activity stage between exposure to illness or between resolution of infection (the disease ended) to the next flare.
