Answer:
The correct answer will be option A - A-band.
Explanation:
The sarcomere is the repeating unit of a myofibril which extends between two z-lines. Under a microscope, a sarcomere can be divided into A- band which is composed of thick myosin only and I-band which consists of thin filament that is actin only.
When a muscle contract then actin and myosin comes in overlapping position due to which I-band shortens and between two z-lines and overlapped structure of thin actin filaments over thick myosin filaments (A-band) is seen.
Therefore, only A-band is seen between two z-lines in a contracted muscle thus, option A is the correct answer.
Lateral position best demonstrates the pathological processes of the retrogastric space
<h3>What is Pathological study ?</h3>
In the field of medicine known as pathology, diseases are studied and diagnosed by examining surgically removed organs, tissues, physiological fluids, and, in rare cases, the entire body (autopsy).
- Sputum, stomach washings, and cervical smear are common illustrations. In forensic pathology, the autopsy procedure is used to examine a corpse after death to determine the cause of death. In dermatopathology, skin conditions are investigated.

<h3>Why is an oral contrast performed?</h3>
- Oral contrast increases the visibility and helps in detailed analysis of the Gastrointestinal (GI) structures on CT scan.
- Computed Tomography (CT) scan is a test that combines X-rays and computer scans.
- Oral contrast helps to opacify the bowel and helps to get better images of the abdomen for diagnosis.
- It makes specific organs to stand out (GI tract) thus for better detection of a disease or an injury.
- Commonly used contrast agents in CT imaging are based on barium and iodine.
- Therefore, the nurse should check first if a patient has iodine allergy.
- Also the nurse should check if any patient has difficulty in swallowing the contrast or his own drool (Dysphagia) as it can be the symptom of a stroke.

<h3>What is cellulitis?</h3>
- A typical skin illness caused by bacteria that can be dangerous.
- The bacteria invade the skin in cellulitis.
- Cellulitis may disseminate quickly. Skin damage causes it to appear bloated, red, and maybe hot and sensitive.
- Cellulitis can be fatal if not treated with an antibiotic.
<h3>How cephalosporin acts against gram-negative bacteria ?</h3>
- The antibacterial characteristics of cephalosporins are used to classify them into generations.
- With less effectiveness against gram-positive bacteria, each successive generation of cephalosporins has much better gram-negative antibacterial capabilities than the one before it.
- The concept of generations linked to pharmaceuticals is not adequately described by any of the remaining possibilities.
