Answer:
Molecular, Microscopic, Cell, Tissue and Organ levels
Explanation:
The natural strength production needed for skeletal muscle to function occurs at the molecular level. You can develop a better knowledge of the properties of cells and tissues by simply studying the molecular systems common to the cells in question. The different muscular level down to myofilaments are:
-
Molecular level — actin and myosin
- Microscopic level — sarcomere and myofibrils
- Cell level — myoblasts and myofibers
- Tissue level — neuromuscular intersections and fascicles
- Organ level — The key skeletal muscles of the body
Answer:
The intra-cellular pathogen is harder to target for the innate immune system because immune system has to by pass the external environment of the organism.
Explanation:
An Infection might be intracellular or extracellular, contingent upon the microorganism. All infections contaminate cells and recreate inside those cells (intracellularly), while microorganisms and different parasites may duplicate intracellularly or extracellularly, contingent upon the species.
The intrinsic resistant framework must react in like manner: by distinguishing the extracellular microbe or potentially by recognizing host cells that have just been tainted.
The innate immune system serves as a specialist on call for pathogenic dangers that sidestep characteristic physical and substance hindrances of the body. Utilizing a blend of cell and atomic assaults, the inborn resistant framework distinguishes the idea of a microorganism and reacts with aggravation, phagocytosis, cytokine discharge, pulverization by NK cells, as well as a supplement framework. At the point when natural systems are lacking to clear a disease, the versatile safe reaction is educated and prepared.
When sarcomeres shorten, the muscle fiber SHORTENS.
Mechanism :
Sacromeres are used to construct the myofibrils, which are a part of the skeletal muscles of animals. They use the sliding filament model to carry out the muscle contraction and relaxation.
To create movement, The cross-bridge between actin and the myosin heads causes the sacromere to shorten. Muscle fibers contract as a result of this shortening of the sacromere, which has the overall effect of shortening the fibers.
