Answer:

The correct answer will be:

1.  Acetylcholine binds to receptors on the motor end plate

2. Chemically-regulated ion channels open, causing depolarization

3  End plate potentials trigger action potential(s).

4. Transverse tubules convey potentials into the interior of the cell

5. Ca++ is released from the sarcoplasmic reticulum

6. Ca++ binds to troponin, pulling on tropomyosin

7. Binding sites on actin are uncovered, allowing myosin to bind and carry out power strokes

8. Force increases.

9. Ca++ is pumped (re-sequestered) into the sarcoplasmic reticulum

10.  Force decreases.

Explanation:

The muscle contraction is a highly controlled mechanism which begins at the neuromuscular junction with the release of the acetylcholine neurotransmitter. This neurotransmitter causes the depolarization of the membrane by binding to the receptors of the motor end plate which generates an action potential. This action potential is transmitted via T-tubules from sarcolemma to the sarcoplasmic reticulum.  

The sarcoplasmic reticulum releases calcium ions which binds to the troponin protein. This troponin removes the protein tropomyosin from the actin causing the rotation of the tropomyosin exposing the binding sites for myosin. The myosin binds to the actin using energy from the ATP which pulls the actin causing contraction. Another ATP binds the myosin head which weakens the bond between myosin and actin which releases the myosin which decreases the force between them decreases and the muscles relax.

In-s [12.5K]

The healthcare provider prescribes a large-volume cleansing enema for a client. The outcome that the nurse identified for the client will be to remove hardened fecal impactions from the rectum.

Enemas are injections of fluids used to wash or excite the depletion of your bowel. This process has been secondhand for ages to treat muscle spasms and identical issues. Constipation is a harsh condition that slows unhappy the drive of your seat. It also forms the seat hard and troublesome to discharge.

The purpose of a washing introduction into the bloodstream search to kindly flush out the colon. It may be urged superior to a colonoscopy or a different health examination. Enema risks contain a breach of the rectum, that demands a section to repair and likely damage to the interior. Furthermore, the “washing” not enough of the rectum and intestine can obstruct your crowd's common incorporation of minerals and fluids, superior to synthetic imbalances.
