The layer of connective tissue, called the _perimysium_ , extends inward from the epimysium and separates the muscle tissue into small sections. these sections contain bundles of skeletal muscle fibers called _fascicles_ .
Additionally, bundles of contractile proteins called fibrils fill a muscle cell, called a fiber. Outside of each fiber, is the connective tissue endomysium. Bundles of fibers form fascicles, surrounded by perimysium. Bundles of fascicles and perimysium comprise the entire muscle organ, which is enclosed by epimysium.
The cells have nuclei that vary in size and shape, termed pleomorphism.
Pleomorphism is usually defined in biology as the occurrence of multiple structural forms during the life cycle of an organism. In anaplasia, it represents multiple structural forms of nuclei. Pleomorphism is a characteristic feature found in malignant neoplasms, and dysplasia, but it can also be found in certain benign cell types.
Answer:
Species interaction- competition, predation, parasitism, mutualism, and commensalism.
The desirability quotient or DQ for methapyrilene is low.
Methapyrilene refers to an anticholinergic and antihistamine of the pyridine chemical category that was formulated in the initial 1950s. It was traded under the names Histadyl EC and Co-Pyronil.
It exhibits comparatively strong sedative influences, to the degree that its main application was as a medicine for insomnia in spite of its antihistamine activity.
