d. oligodendrocytes and Schwann cells

<h2>Further explanation </h2>

Oligodendrocytes can be said to have a function similar to Schwann cells that can be found in the peripheral nervous system.

Neuroglia are the cells most commonly found in the nervous system. These cells do not play a direct role in information processing and transmission and function to support the needs of neuron cells.

Microglia are a type of glial cell that is part of the immune system for the central nervous system. Microglia are small cells that act as phagocytes, cleaning components that can threaten the nervous system.

Oligodendrocytes are cells that play a role in forming the myelin sheath for the central nervous system. These oligodendrocytes can be said to have a function similar to Schwann cells found in the peripheral nervous system.

Astrocytes

"Astrocytes" comes from two words "Astro" which means stars and "sit" which means cell. As the name implies, erythrocytes are glia cells that have a star-like shape. Astrocytes are the most numerous cells in the central nervous system. This cell has several important functions, namely:

Bringing together neurons
Repair of brain injury
Play a role in neurotransmitter activity

There are two types of astrocytes

Protoplasmic astrocytes, more commonly found in the substance grise. These cells have bulges from the cytoplasm that spread from the entire cell surface. Sometimes this cytoplasmic expansion ends in small blood vessels to form "perivascular feet".
Astrocyte Fibrosa, commonly found in the substance of alba. The difference with protoplasmic astrocytes can be seen from the cytoplasmic protrusion that is longer and straighter. Inside the bulge can also be found a picture of the filament.

Ependymal Cell

Ependymal cells line the interior of the fluid-filled cavity in the CNS. Ependymal cells are cells that have cilia, the movement of these cilia play a role in flowing cerebrospinal fluid throughout the ventricles of the brain.

Answer:

The correct answer is option D- oligodendrites and Schwann cells.

Explanation:

Neuroglia or glial cells are the cells in the nervous system which support, protect and maintain the neurons. These neuroglia cells protect the neurons as they insulate the axons and dendrite by forming a sheath around the neurons called the 'myelin sheath".

Two different types of glial cells form this myelin sheath in CNS and PNS: Schwann cells in PNS while oligodendrocytes in CNS. These myelin sheaths provide insulation as they are formed by the spiral wrapping of the plasma membrane which is made up of hydrophobic molecule.

Thus, option D- oligodendrocytes and Schwann cells are the correct answer.

Alan is most likely to be diagnosed with somatoform disorder.

<h3>What is Somatoform disorder?</h3>

This is the type of disorder which is a mental illness and also characterized by various types of symptoms such as body pain.

In this scenario, there was no physiological basis for Allan's complaint. This means the illness is a mental one and the availability of symptoms is why somatoform disorder is the most appropriate choice.

A vasectomy is a minor surgical procedure to prevent unplanned pregnancies. Even though it is a minor procedure, not many men el

iren2701 [21]

Given what we know about the social stigma surrounding a vasectomy, we can confirm that this surgery is not commonly utilized due to a lack of information on the procedure and the social factors that influence this.

A vasectomy, as stated in the question, is a minor surgical procedure in which the vasa deferentia of the male genitalia are cut so as to prevent the passage of sperm. The male in question would still be able to ejaculate, although the substance released would be void of sperm cells that can cause fertilization, though this is not always completely effective.

In North American culture, the rate at which males see their doctors and get regular check-ups is very low in comparison to countries elsewhere in the world. This is a possible reason as to the also observed differences in the rate of vasectomies in these regions.

The social stigma that has surrounded the vasectomy is one that leads males to believe this is an emasculating procedure or that it is an irreversible process that will leave them sterile for life. This popular myth is one that greatly influences the low vasectomy rates for North American males, one that has been found to be inaccurate.

a nurse is conducting a refresher program for a group of nurses returning to work in the newborn clinic. the nurse is reviewing

White raven [17]

In a refresher program, the nurse determines that additional education is needed when the group identifies blood pressure being included in the assessment of vital signs in healthy newborns and infants.

A refresher program is meant to bring learners back to the fundamentals, so they'll review a number of the basics they'll have forgotten, or brush up new information they'll not bear in mind of.

Blood pressure is a condition within which the force of the blood against the artery walls is simply too high. Usually high blood pressure is outlined as force per unit area on top of 140/90, and is taken into account severe if the pressure is on top of 180/120. consumption a healthier diet with less salt, sweat often and taking medication will facilitate lower blood pressure.
