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.

Answer:

Etymology of

Soma

from Greek sōma ‘body’.

Cell's body, this part of the cell receives information, and it contains the cell's nucleus.

Etymology of dendrite

from French, from Greek dendritēs ‘treelike’, from dendron ‘tree’.

thin filaments carry information from other neurons to the soma, they act as input part of the cells

Etymology of Axon

 (denoting the body axis): from Greek axōn ‘axis’.

long projection carries information from the soma and sends it off to other cells. This is the “output” part of the cell.

In these cases the ICD-10 for this patient is ICD 10 - L93 Lupus ICD 10 N13. 2 Hydronephrosis with obstruction by renal and ureteral calculi.

1. Abnormal antinuclear antibody positive for lupus. - CID 10 - L93 Lúpus eritematoso

2. Nephrosis. ICD 10 N13. 2 Hydronephrosis with obstruction by renal and ureteral calculi.

<h3>What does the ICD mean?</h3>

The International Classification of Diseases and Related Health Problems, better known as the ICD, is one of the main epidemiological tools in everyday medical practice. The main function of the ICD is to monitor the incidence and prevalence of diseases, through universal standardization.

With this information, we can conclude that ICD-10 is the 10th revision of the International Statistical Classification of Diseases and Related Health Problems
