A muscle fiber contains many myofibrils, which are cylinders of muscle proteins. These proteins allow a muscle cell to contract. Myofibrils contain two types of filaments that run along the long axis of the fiber, and these filaments are arranged in hexagonal patterns. There are thick and thin filaments.hese proteins allow a muscle cell to contract.

Cocklebur (Xanthium strumarium L.) is a large, annual broad-leaved weed with an erect, branched stem and broadly triangular leaves (Figure 1). The stem is rough-hairy, spotted with purple and up to 1.5 m high. The leaves are alternate on the stem, with toothed or lobed margins and rough-hairy surfaces.
Quite a lot are made up, that is part of the fun really. I have never heard cockwomble in the wild personally but I can see it is a fairly humourous insult. The Wombles are a kid's puppet / stop-motion show from the 70s, they are little furry creatures who live in Wimbledon Common. A cock is a penis of course.
