Answer:

When the level of calcium ions declines the sarcoplasm stops the sliding.

Explanation:

Sarcoplasm can be described as the cytoplasm for the cells of muscles. It contains important structures such as the myofibrils.

The following steps would occur when the level of calcium ions would decline:

The sarcoplasm would stop the sliding of the thin filaments.

The actin filaments would be migrated in the M line

This would lead the bands in the I region to shorten.

The Z region would compress.

The H region would diminish.

TiliK225 [7]

Answer:

A cell is defined as the structural and functional unit of an organism.

The average size of the prokaryotic cell lies between 0.1 to 10 micrometers whereas the average size of the eukaryotic cell is approximately 25 micrometers.

Four things are found in all the cells: genetic material (either DNA or RNA), cell membrane, cytoplasm, and the ribosome.

All the living cells grow and reproduce (sexually or asexually) and have the ability to respond to stimuli.

Describe the major differences in acute versus passive range of motion (rom) when distinguishing between an articular and nonart
Ierofanga [76]
The question should be about active vs passive range of motion.

In the active range of motion, the test is done by asking the patient to move their body themselves. In this case, the patient should use their muscle to move their body. If there is a restriction in this examination, it could be caused by the muscles or the joints, or the nervous system that used to contract the muscle.
In the passive range of motion, the test is done by the examiner moving the patient body. Since no muscle used, the test shouldn't be influenced much by the muscle. Then, if there is an articular joint issue, the restriction would be found in both passive and active ROM, but the nonarticular joint issue might only cause abnormality in the active ROM.
