A patient who is undergoing intravenous therapy should not perform isometric exercises because it may lead to bleeding and injury at the injection site. During a shower, the patient should protect the injection site and dressing from getting wet by covering it with plastic. Applying pressure with sterile gauze at the injection site if the catheter falls out helps to reduce bleeding. Inflammation and itching at the injection site may be an indication of infection and phlebitis; the patient should report these manifestations immediately.
The mucosa secretes mucus. Found in the naval cavity, it contains bipolar neurons, also known as olfactory cells, which are very important for being able to have a sense of smell. The dendrites of these olfactory cells reach out of the surface of the mucosa. The axons of these cells are actually bundled together. There are about 20 of these bundled axons, and collectively they are known as the olfactory nerve or the first cranial nerve.
Anatomically, it passes through the cribriform plate found in the ethmoid bone, having synapse with the olfactory bulb, an essential neurological connection that allows the sensation of smell to work. The first cranial nerve can actually be tested by closing one nostril and holding up a smelly object to the other opened nostril to see if the sense of smell is still working. The nasal mucosa is also continuous the sinuses, which not only help warm and moisten the inhaled air, but also provide resonance to the voice and give the face more shape.
The answer to your question is ( true )
Answer: B
Explanation:
After a muscle fiber is stimulated by a nerve signal, a release of stored calcium ions leads to muscle contraction.
Common electrolytes include sodium, chloride, magnesium, calcium and potassium.
Sodium and potassium help in the generation of nerve impulses while calcium aids muscle contraction. Sodium is also actively involved in the movement across cell membranes.
