Consider the factors that affect muscular strength. Read each scenario and then click and drag each label into the appropriate c
ategory based on whether each would result in a stronger or weaker muscle contraction. 1- Potassium accumulate in the sarcoplasm
2- Increase in muscle belly circumference
3- Lesser proportion of motor neurons to muscle fibres
4- Begin contractions with muscle already 50% contraction
5- Lower sarcoplasm pH
6- Increased stimulus frequency.
7- Circular arrangement of muscle fascicles
8- increased requirement
Muscles that are elongated while activated (i.e., eccentric muscle action) are stronger and require less energy (per unit of force) than muscles that are shortening (i.e., concentric contraction) or that remain at a constant length (i.e., isometric contraction)
stronger muscle contraction includes:
Potassium accumulate in the sarcoplasm
Increase in muscle belly circumference
Increased stimulus frequency
Increased requirement
Lesser proportion of motor neurons to muscle fibers
weaker muscle contraction includes:
Begin contraction with muscle already 50% contracted
Extracellular matrix is a term used in biology for molecule outside the cell that has a role in structural or biochemical function. The example would be collagen and elastin, strong and elastic protein that could be found in the skin. These protein is released by a certain cell, so its location is not inside the cell and it is not cellular.
If I recall from my class that it healthy life sytle and may be prevented through immunization I don't remember which but i know its maintain a healthy life style
