What is the condition in which the patient's pupils are normally unequal?

andrew11 [14]

The correct answer is "anisocoria". Anisocoria is the condition when the patient's pupils are normally unequal and the patient is asymptomatic and clinically stable. This should be differentiated in cases of patient with a relative afferent pupillary defect such is patients with optic neuritis or retinal detachment or in patients with neurological deficits.

Answer:

A- Sensory Neuron

B- Spinal cord

C- Effector neuron

D - Brain

Explanation:

Sensory neuron: Its main function is to allow the reception of stimuli that are transformed into nervous impulses and electrical signals, capable of realizing sensations, such as a peliscão, for example. These impulses are transmitted to the spinal cord.
Spinal cord: The main function is to support the body in an upright and vertical position. It also has the function of transmitting electrical signals and nerve impulses between some parts of the body and the brain.
Effector neuron: Its main function is to receive muscle stimuli capable of creating muscle contractions. These neurons are located in the spinal cord.
Brain: the processing center receives all the stimuli sent by the bone marrow. Its main function, in this case, is to produce bodily responses to the stimuli it has received, producing muscle movement.

Modify the existing vector's contents, by erasing the element at index 1 (initially 200), then inserting 100 and 102 in the show

Aleonysh [2.5K]

Answer:

Following are the code to this question:

#include <iostream>//defining header file

#include <vector>//defining header file

using namespace std;

void PrintVectors(vector<int> numsList)//defining a method PrintVectors that accept an array

{

int j;//defining integer variable

for (j = 0; j < numsList.size(); ++j)//defining for loop for print array value

{

cout << numsList.at(j) << " ";//print array

}

cout << endl;

}

int main()//defining main method

{

vector<int> numsList;//defining array numsList

numsList.push_back(101);//use push_back method to insert value in array

numsList.push_back(200);//use push_back method to insert value in array

numsList.push_back(103);//use push_back method to insert value in array

numsList.erase(numsList.begin()+1);//use erase method to remove value from array

numsList.insert(numsList.begin(), 100);//use insert method to add value in array

numsList.insert(numsList.begin()+2, 102);//use insert method to add value in array

PrintVectors(numsList);//use PrintVectors method print array value

return 0;

}

Output:

100 101 102 103

Explanation:

In the above-given code, inside the main method an integer array "numList" is defined, that use insert method to insert value and use the erase method to remove value from the array and at the last "PrintVectors" method is called that accepts a "numList" in its parameter. In the "PrintVectors" method, a for loop is declared, that prints the array values.
