The factors that associates the causes for central nervous system defects are:
- Unbalanced cerebrospinal fluid
- Deformation of the neural tube during embryonic development
Problems originating from an imbalance of CSF fluid (such as hydrocephalus) and a variety of disorders developing from abnormalities of the neural tube during embryonic development are examples of central nervous system defects (often called neural tube defects). The other choices do not result in central nervous system flaws.
<h3><u>What are cogenital disorders ?</u></h3>
An illness that is present from birth is referred to as congenital. Environmental or hereditary factors may contribute to congenital diseases. They occasionally have very little, if any, influence on a child's health and development. A kid with a congenital condition, however, may live with a handicap or health issues all of their lives.
If you're pregnant or planning a pregnancy, it's normal to be worried about congenital abnormalities, especially if that disorder runs in your family. While not all congenital abnormalities can be detected during pregnancy, some may be, and there are steps you can do to lessen the likelihood that your child will be born with one.

hey! thank you so much for free points!
have a good day! God bless you
If you believe that patient should be given nitroglycerin but you do not have offline protocols for this, then so you should contact medical direction.
<h3>Why does the professional should contact medical direction?</h3>
A professional should contact the corresponding medical direction in order to obtain advice and/or directives about procedures to follow which are in doubt.
In conclusion, if you believe that patient should be given nitroglycerin but you do not have offline protocols for this, then so you should contact medical direction.

Answer:
Since this question has multiple subquestions in it, I will give you the answer to them as follows:
1. Which neuron would activate a muscle? They are called multipolar neurons, they are found mostly originating from the CNS itself and they are multipolar because when a neuron stimulates a muscle, one signal from just one terminal is not enough; it requires the stimulation from several neurnal terminals.
2. Which neuron would be found in the retina of the eye? A bipolar neuron. This is because these neurons will fulfill a double function: to activate the muscles of the retina, and also they will convey messages taken by the sense of sight, towards the brain for interpretation and integration.
3. Which neuron is a sensory neuron found in a reflex arc? The answer again is a unipolar neuron. These neurons will not reach the brain itself, but rather the reflex arc site on the spinal cord. Their task is to relay sensations from the site that has been stimulated to the spinal cord and from there to the affected place, with the correct response.
4. Which neuron is never myelinated? Again the answer is the bipolar neurons found connecting the retina and the eyes. The reason is that these neurons are capable of relying fast messages to and from the brain, whereas in myelinated ones, messages go slower due to the myeling sheaths.
5. Which neuron is typically involved in the special senses of sight and smell? Once more the answer is the bipolar neurons that are most commonly found connecting the different organs of these two senses. Since these have such unique capabilities: relying information for integration and sensory and motor responses, their action potentials travel fast, and have a short distance to go.
Answer:
The correct answer is C. Normal host cellular prion proteins (PrPC) are converted into scrapie proteins (PrPSc).
Explanation:
Prions are the infectious proteins that cause neurodegenerative diseases in both animals and humans. In humans, it causes various diseases like Creutzfeldt-Jakob disease, kuru. Collectively these diseases are called spongiform encephalopathies.
Humans contain normal cellular prion protein denoted as(PrPC) and the prions are abnormal form of this protein i.e., PrPSc where Sc indicates scrapie. This abnormal protein is misfolded form of normal prion protein.
When this misfolded prion protein enters the host body it converts all the normal cellular prion proteins in scrapie protein causing a fatal disease. In this disease, holes are created in the brain tissue and tissue degeneration gives brain appearance like sponges. Therefore the correct answer is C.
