Answer:
The correct answer will be option D-all of the above.
Explanation:
Neuroglia or glial cells are the additional cells of the nervous system which perform functions which maintains the neuron cells. They protect, support and nourish the neurons which are present in both CNS and PNS.
In CNS four types of glial cells are found namely:
1. Astrocytes- support and nourish the neurons.
2. Microglial cells- become macrophages which clean neuronal debris.
3. Ependymal cells- help circulation of cerebrospinal fluid which maintains neurons in their place.
4. Oligodendrocytes- form the myelin sheath.
In PNS two types of glial cells are present:
1. Schwann cells- form myelin sheath and perform the function of macrophages.
2. Satellite cells- support and nourish.
Therefore, glial cells perform all the functions thus, option D is the correct answer.
Aortic aneurysm occurs when a circulating clot moves through the heart to the lungs, blocking an artery supplying blood to the lungs.
<h3>What is Aortic aneurysm?</h3>
- A balloon-like protrusion known as an aortic aneurysm develops in the large artery known as the aorta, which carries blood from the heart through the chest and body.
- The strain of blood pumping can tear the layers of the artery wall, enabling blood to seep in between them. Aortic aneurysms can rupture or dissect.
- The following are symptoms and warning signs of an aortic aneurysm rupture: Back or abdominal pain that comes on suddenly, is quite strong, and lasts for a long time, reduced blood pressure, fast heartbeat
- A ruptured aneurysm can be hazardous and typically fatal if there is significant internal bleeding. 8 out of 10 persons with a rupture either pass away before they reach the hospital or are not successful surgical candidates.

Answer:
Here options b,c,d, e are correct and only option a is incorrect.
Explanation:
Option a is wrong because smooth muscle fibers are those fibers which are commonly found in a persons stomach or even in the intestines , so therefore we can definitely say that tongue is not made up of smooth muscle fibers.
Option b is right , tongue is made up of striated muscle fiber and not only this tongue actually consists of eight types of muscles which includes both intrinsic and extrinsic types of muscles.
Lingual mucosa is nothing but a gland which forms the surface of the tongue, that helps in getting sensory reception for the taste , as this mucosa consists of nerve endings that help a person in taste perception.
Option d is also correct as this hypoglossal nerve provides a somatic motor function to the tongue by innervating almost all of the muscles of tongues except the palatoglossus muscle.
the last option is also correct as tongue plays a very important part in the digestive and respiratory functions of the body. Tongue helps in digestion of the food because tongue helps us in tasting the food and properly mixing the food with the saliva, that will create bolus , that is further pushed in to oesophagus.
