Most pigments are accumulated by specialized cells, termed pigment cells, derived early in embryonic development either directly from the neural plate (e.g., pigmented retinal epithelium (PRE) and the pineal organ pigment cells) [1] or from the neural crest [2] and [3] .
Both the fascia and soffit are part of the exterior of the home and should be painted every 5-7 years, just like the exterior of a home. It is very common for the fascia to rot in older homes if it isnât painted often enough.The paint protects the fascia and soffit from the natural elements of weather.ain gutters are attached to the fascia, but an easier way to describe where the fascia is located is to say that it is what the Christmas lights are attached to. The fascia can be made up of any type of wood and size (2Ã4, 2Ã6 or 2Ã8).
Typically a soffit is used in the area beneath the eaves on the exterior of a house to close the space beneath the eave. The soffit extends from the side of the structure to the edge of the eave. Fascia is used to create a barrier between the edge of the roof and the outside.ascia is important to a properly constructed roof and is typically installed beneath the roof line and behind the gutters. Fascia is installed around the entire structure and is attached to the uncovered ends of rafters or to the top of exterior walls.
