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:

What is an ultrasound?

Its general definition is ultrasound, the process of imaging high-frequency sound waves. Unlike many other methods, X-rays, which are called radiation, are not used in ultrasonography. This means that it is a harmless process. It can be used safely in pregnancy follow-up, babies and children. Performing ultrasonography shows the quality of the images obtained according to the region of the procedure. When the ultrasonography process is examined, it is performed by radiology specialists trained in ultrasonography and other imaging methods. The ultrasound process is transmitted by direct contact with a special device to send the interview. As an ultrasound device, this instrument consists of 2 parts. One of them is the probe to be brought into contact with the skin, the other is the central processing unit that converts sound waves into images and reflects them. The area where the probe is contacted is covered with a special gel so that the sound waves can be fully transmitted. The images obtained during the process are real-time and controlled by the radiologist by projecting them on the monitor.

Ultrasonic sound waves; It undergoes tendencies such as scattering, scattering, reflection depending on the size of the organ under study or its size, condensation, homogeneity, temperature and many other factors. The images obtained in this work are evaluated considering these. Organs and formations with large and flat surfaces are the most clearly shaped phenomena in ultrasound. The validity of the medical interpretation made by examining the obtained images is directly proportional to the experience and success.

How is an ultrasound done?

Many people, especially pregnant women and people with chronic diseases, undergo regular ultrasound for health screenings. In order to see the area investigated in ultrasonography most clearly and to increase the accuracy of the findings to be obtained, physicians should give the necessary information to the patients about the things to be considered before the ultrasound. Certain ultrasound procedures, such as abdominal ultrasound, may require fasting for a certain period of time. In addition, the bladders of the patients must be full while entering the pelvic ultrasounds to investigate the diseases related to the female reproductive organs. It is of great importance to pay attention to such matters before the procedure in order to achieve the purpose of the transaction.

Before starting the ultrasound, the entire area to be viewed by the radiologist is covered with transparent ultrasound gel. This gel is a substance that does not cause any negative effects in terms of health and only provides lubrication of the area and facilitating the transmission of sound waves. Because it is water-based, it can be easily cleaned with the help of water after the process. After the preparations before the procedure are completed and the necessary information is given to the patient, the probe part of the ultrasound device is moved over the area to be displayed and the images are monitored on the monitor. During imaging, the radiologist may press the probe to the skin to get a better and clearer image in some areas. This is normal and does not cause any harm. After the imaging process is completed, some printouts are taken from the images obtained and a report regarding the transaction is prepared. This report is sent to the medical unit requesting the ultrasound.

In what areas is ultrasound used?

Ultrasonography is one of the most widely used imaging techniques in the field of medicine, which is developed to diagnose diseases related to these regions by imaging the parts of the body that are invisible and cannot be accessed by endoscopy method, and to observe changes and developments. The organs in the abdominal cavity provide diagnosis and treatment in many areas, especially breast screening and pregnancy follow-up. The main areas where ultrasound is used can be stated as:

Screening for the health status of the baby in pregnant women

Detection of possible malfunctions in the working order of the heart

Investigation of various infections

Detection of gallstones and diseases

Investigation of tumors in breast and soft tissues

Investigations for muscle diseases

Investigation of prostate and genital area diseases

Providing imaging in needle interventions in cyst and biopsy treatments

Investigation of thyroid gland diseases

Por qué el cuerpo humano tiene entre 206 y 208 huesos? Como están compuestos los Miembros inferiores? (Aclarar sus partes).
Darya [45]

Answer:

El cuerpo humano posee 206 huesos (208 huesos teniendo en cuenta huesecillos del oído medio)

Miembros inferiores > fémur, tibia, peroné, tarso, metatarso y falanges.

Explanation:

En adulto se compone de 206 huesos, pero algunos autores sostienen que el cuerpo humano está compuesto por 208 huesos debido a que el hueso del estribo (estapedio) perteneciente a la cadena de huesecillos del oído medio se suele considerar como dos unidades independientes (lenticular y estribo), dando así lugar a un total de 208 huesos. Por otra parte, otros autores también han considerado la posibilidad de que el cuerpo humano está compuesto por 208 huesos debido a variaciones en el número de las vértebras. Los huesos de miembros inferiores se dividen de acuerdo a su localización en huesos del muslo, de la pierna y del pie. El muslo contiene un sólo hueso conocido como fémur (el hueso más largo del cuerpo). La pierna posee dos huesos llamados tibia y peroné los cuales se disponen paralelamente. La tibia es más larga y gruesa que el peroné debido a que la tibia soporta todo el peso de la articulación. Finalmente, el pie se compone del tarso, el metatarso y las falanges (huesos de los dedos). El tarso posee siete huesos (calcáneo, astrágalo, navicular, cuboides y tres cuñas), mientras que el metatarso posee cinco huesos (primero, segundo, tercero, cuarto y quinto). Al igual que en los miembros superiores, el dedo gordo del pie posee dos falanges conocidas como proximal y distal, mientras que los cuatro dedos restantes poseen tres falanges (proximal, media y distal).

the client who has an immobilizer on the arm reports shortness of breath following ambulation to the bathroom. the nurse notes t
Talja [164]

The complete question with options are:

Only a small range of motion

Clients mention feeling out of breath

Lowering of blood pressure raising of respiratory rate

Increasing heart rate

The client's defining characteristics for this diagnosis are, clients report feeling short of breath, which is accompanied by an increase in heart rate and respiratory rate and lowering of blood pressure.

What is meant by immobilizer used on the arm?

While your shoulder recovers, you can use a shoulder immobilizer to prevent your arm from moving. Due to the fact that your arm is kept close to your body, it differs from a sling. Typically, an immobilizer has a wrist band, arm band, and chest band. The chest band will hold each band in place.

In order to keep patients from engaging in any physical activities involving the injured shoulder for the first 4-6 weeks following rotator cuff repair surgery, patients are frequently instructed to wear a sling or brace.
