What are the steps of a contraction at the Neuromuscular Junction?

Answers

Answer 1

Answer:

All the steps are down below!!

Explanation:

Step 1 - Motor neuron sends action potential (nerve impulse) to the muscle

Step 2 - acetylcholine (ACh) release from vesicles on motor neuron

Step 3 - ACh binds to receptors on muscle membrane & activates 2nd action potential, now on muscle

Step 4 - Action potential opens active transport pumps of sarcoplasmic reticulum

Step 5 - Ca+2 floods sarcoplasm, AChE degrades ACh

Step 6 - Ca+2 attaches to troponin of TT complex and changes its shape

Step 7 - This shape change pulls tropomyosin away from myosin-binding sites on actin

Step 8 - ATP attaches to ATP binding site on myosin crossbridge

Step 9 - ATP use on myosin head in presence of Mg+ splits ATP into ADP+P which energizes myosin head (swings forward)

Step 10 - P flies off and myosin head binds to binding site on actin

Step 11 - DP is pushed off + myosin head is de-energized (pulling actin forward) non myosin swivels back to resting state

Step 12 - Repeat 8-11 until the Ca+2 comes off the TT complex

Hope this Helps!!

Explain the challenges that teenagers must deal with in having their bodies develop more quickly than their emotions

Answers

About teenage moods

Moods, or emotional ups and downs, are a normal part of life for young people, just as they are for adults.

It’s normal for teenagers to feel cheerful and excited some days, and down, flat, low or sad at other times. It’s also normal for teenagers to want more privacy or time on their own. In the teenage years, these emotional ups and downs can happen more often than they used to, and they can be more extreme.

Your child’s emotional ups and downs might happen for many reasons – physical, emotional, social and psychological – and not for any one reason in particular. Often you won’t be able to pin down why your child feels up or down – and neither will your child.

Of the options, straddle injuries only happen with trauma in the groin area; not a spinal cord injury.

Goodpasture syndrome is an auto-immune disease that has nothing to do with trauma.

Interstitial cystitis is a bladder disease causing bladder pressure and pain; again nothing to do with trauma.

A plaintiff sued an industrial facility in her neighborhood for injuries to her health caused by air pollution. At trial, the plaintiff was asked questions on direct examination about the days on which she had observed large amounts of dust in the air and how long the condition had lasted. She testified that she could not remember the specific times, but that she maintained a diary in which she had accurately recorded this information on a daily basis. When her attorney sought to refresh her recollection with her diary, she still could not remember. The plaintiff's attorney seeks to have the information in the diary admitted at trial.
Is the information admissible?

Answers

Answer:

The missing options are:

A No, because reviewing it did not refresh the plaintiff's recollection.  B No, unless it is offered by the defendant.

C Yes and the plaintiff should be allowed the option of reading it into evidence or having the diary received as an exhibit.

D Yes, and the plaintiff should be allowed to read the diary into evidence.

The correct answer is D.

Explanation:

The information in the diary is admissible because the testimony that the witness gave is not enough or accurate. With the diary, what the witness stated can be completed since it is a complement of what she said. It is valid because she wrote it and assures that the information documented in there is correct and was written by someone that is in a good state of mind and health to do so.
