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.

Explanation:
The bisecting angle technique is used for dental radiography based on the principle of projecting the x-ray beam at the right angle.

A hemostat is not necessary since this is a scanning technique and the bite block isn't either since the patient needs to have his or her mouth open.
When you have a runny nose, "brain fluid leaking" typically isn't the first thing that comes to mind.
<h3>Why does CSF flow out of my nose?</h3>
The skull bone injury causes CSF to seep through the nose. Drainage of clear, watery fluid through one or both sides of the nose is the most typical sign of a CSF leak. When bending forward, tilting the head, or straining, this leaking can get worse.
<h3>Why is clear fluid dripping from my nose?</h3>
Allergies and illnesses like the common cold and influenza are the most frequent causes of clear liquid pouring from the nose. Another cause of a persistent runny nose is vasomotor rhinitis, in which there is no obvious reason why the condition exists. A leaking nose can be caused by nasal polyps, migraines, foreign bodies, and, very rarely, certain tumors.

<h3>What is the remedy for a digitalis overdose?</h3>
Digoxin immune fab, an anti-digoxin immunoglobulin antibody, is the main treatment for digoxin toxicity. Digoxin toxicity symptoms such hyperkalemia, hemodynamic instability, and arrhythmias have been demonstrated to be extremely responsive to treatment with this antidote.
<h3>Digoxin toxicity: what causes it?</h3>
Hypokalemia, which can happen as a result of diuretic medication, is the most typical cause of digoxin poisoning. Dosing mistakes are another frequent reason for toxicity in younger people. The risk of digoxin toxicity is affected by a number of factors, such as:
