Explanation:
Answer:
A) the concentration of calcium ions in the sarcoplasm of a resting muscle
Explanation:
Sarcoplasmic reticulum is a system of the membranous sac that is present around each myofibril and is filled with calcium ions. When muscles are in the resting stage, calcium ions are stored in the sarcoplasmic reticulum.
As the muscle action potential triggers change in voltage-gated calcium ion channels of the sarcoplasmic reticulum, the channels are opened to release the calcium ions in the sarcoplasm. Increased calcium ion levels in sarcoplasm make the muscle fibers to contract.
Removal of acetylcholine from the synaptic cleft ends the production of muscle action potential and calcium ions are moved back from the sarcoplasmic reticulum.
Hence, lower levels of calcium ions are maintained in sarcoplasm when the muscles are in the resting stage.
The staff unit should conduct Debriefing.
Debriefings are usually in small unit and crew activities, and this is in context
of a training shown to improve Knowledge, Skills, and Abilities (KSAs)
significantly when conducted formally using pre-defined measures of performance
derived from front-end analysis. Debriefings are very effective when conducted
actively between the person of the immersive activity and the assessment or observation
personnel.
