Acetylcholine receptor locales are blocked. Acetylcholine receptors are found on the surface of muscle cells, moved in the neurotransmitter between nerve cells and muscle cells. It is ligand-gated particle channels, and, as different individuals from the "Cys-circle" ligand-gated particle channel superfamily, are made out of five protein subunits symmetrically organized like fights around a barrel.

when matter i’m plants and animals decay, microorganisms responsible for the decomposition process are doing cellular respiratio
uysha [10]

Answer:

Yes, when the plants and animals die, decomposers such as bacteria and fungi etc which are microorganisms feed on these dead bodies of plants and animals and broken down their bodies into simpler substances. This decomposition occurs both with oxygen and without oxygen. When energy is released with the addition of oxygen, this process is called aerobic respiration while when energy is released without the use of oxygen, this process is called anaerobic respiration.

In a car accident, ryan sustained significant damage to the acetabulum on the right side. arthroplasty to address this is best d
Digiron [165]

The answer is Total Hip Arthroplasty (THA).

Total hip arthroplasty (THA) is a well-accepted treatment for established hip arthritis following acetabular fractures. If a conservatively treated or operated case progresses to a nonunion/malunion that does not restore  joint integrity, secondary arthritis may eventually develop, warranting  total hip arthroplasty. In addition, in recent years, acute total hip arthroplasty has gained importance in conditions where the fracture occurs with pre-existing hip arthritis, cannot be salvaged by  open reduction and internal fixation or a poor prognosis after hip replacement is expected.

What is an Acetabulum?

  • The hip is one of the  largest joints in the body. It's a "ball joint". The cavity is formed by the acetabulum, which is part of the pelvis. The ball is the femoral head, which is the top of the femur (thigh bone).

How is an acetabular fracture diagnosed?

              Emergency Stabilization

  • Patients with fractures caused by high-energy trauma are almost always referred or presented to an emergency center or emergency department for initial treatment because of the severity of their symptoms.

  • If the fracture is due to high-energy trauma, head, chest, abdominal, or leg injuries may also be present. Significant blood loss can lead to shock, a life-threatening condition that can lead to organ failure.

               Physical Examination

  • Your doctor will perform a full examination of your pelvis, hips and legs. He or she will also check that you can move your ankles and toes and feel  the soles of your feet. In some cases, nerves can be injured at the same time when the acetabulum is fractured.

  • Your doctor will also carefully examine the rest of your body to see if you have suffered any other injuries.

              X-rays

  • These studies provide images of dense structures such as B. Bone. X-rays of acetabular fractures are taken from  different angles to show the fracture pattern and the misalignment of the  bones  (displacement).

  • Computed Tomography (CT) Scans Because of the complex anatomy of the pelvis, a CT scan is often ordered for acetabular fractures. The scan provides your doctor with a more detailed cross-sectional image of your hip and can help with preoperative planning.

I am to lazy to write this so somebody answer these please
bezimeni [28]

Answer:

1. Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

2.Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Explanation:

3.Both photosynthesis and respiration involve the conversion of energy from one form to another through a series of biochemical reactions. Both processes use and produce ATP in reactions that are carried out on membranes and are controlled by enzymes.

4.Both photosynthesis and respiration involve the conversion of energy from one form to another through a series of biochemical reactions. Both processes use and produce ATP in reactions that are carried out on membranes and are controlled by enzymes.
