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.
up vote 0 down vote favorite. The latent period is the time between the start of depolarisation and the start of contraction. I know that the contraction of ventricles starts after sufficient influx of Ca2+ and threshold potential is met. The influx of Ca2+ is at start of Phase 2, so Phase 0 and 1 are included in the latent period. Comparing to electrocardiogram is not simple, since there is always at least some time lag between the event and the recording. I think there not much sense to compare cellular model events to ECG recordings here.
