In-s [12.5K]3 years ago
8 0

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.

the nurse obtains a medical history from a aptient that is admitted to the ed using the mneominic sample to gather which patient
Phoenix [80]

A nurse obtains a medical history from a patient that is admitted to the emergency department, using the mnemonic AMPLE to gather:

B. Food allergies

C. Previous Medications

E. Tetanus vaccination

  • The nurse gathers information on the disease, the amount of time after the incident, the therapy given, the patient's reaction, and degree of consciousness during the secondary survey.
  • The acronym AMPLE reminds nurses to inquire about A, drug, food, latex, and environmental allergies; M, medication history; P, past health history, tetanus, and immunizations; L, last meal; and E, incidents or environmental factors that contributed to the illness.
  • Before assessing the health history at the beginning of the secondary survey, the nurse checks the patient's vital signs and blood pressure.

DISCLAIMER

A nurse obtains a medical history from a patient that is admitted to the emergency department, using the mnemonic AMPLE to gather what patient information? Select all that apply.

A. Blood pressure

Steroid hormones are stored and then released in large quantities into the blood. Sperm is stored and matures in the epididymis.
Rasek [7]

Answer:

Considering these as two questions with the same purpose of answering if they are true, or false, these would be the answers and explanations:

1. Steorid hormones are stored and then released in large quantities into the blood?, the answer would be: False. Steroid hormones, given their excitatory function, are usually not stored and simply released in large quantities into the blood steam. Rather, they will be produced as the different systems, especially the reproductive system, requires them, and will be released when nerve signals initiate the process of release of them, especially during puberty, when they are most needed, and later on, during reproductive life. But these are not released in great quantities, nor are they stored. They are produced as needed.

2. Sperm is stored and matures in the epididymis, this is True. Sperm is usually produced by the testis, the male reproductive organs per se. However, these sperm are still in need of maturation, and this they achieve in the epididymis, especially in the head and body of this organ that sits atop the testis. As the sperm matures, they move towards the tail of the epididymis, and are stored there for use.
