The membrane layer that wraps around individual organs is called the visceral pleura.
myofibril
myofilament myofibril myofiber fascicle muscle
The connective tissue surrounding the fascicle of a muscle is the perimysium.
A fascicle is wrapped in perimysium, which is a connective tissue sheath that surrounds bundles of muscle fibers. It provides structural support and helps protect the muscle fibers within the fascicle.
The extensor digitorum longus muscle has a parallel fascicle arrangement where muscle fibers run parallel to the long axis of the muscle. This arrangement allows the muscle to generate a strong pulling force to extend the toes.
It depends on what type of wrap you are referring to. Polo wraps are fleece. Standing wraps can be cotton or lycra. Pillow wraps are quilted cotton or fleece And the list goes on...
The Fascicle
fascicle
A cell performs pinocytosis when it needs a fluid that's outside of the cell. It does this by taking in the fluid particle in through the cell membrane. It wraps the particle in a layer of the membrane. See the related link for an example.
