Answer:
<em>C.)</em><em> Snap-a-ray</em>
Explanation:
The bisecting angle technique is used for dental radiography based on the principle of projecting the x-ray beam at the right angle. It is non-intrusive and the patient is awake while it is happening. A hemostat is not necessary since this is a scanning technique and the bite block isn't either since the patient needs to have his or her mouth open.
Answer:
The lists are Estimated Average Requirements (EAR), Recommended Dietary Allowances (RDA), Adequate Intakes (AI), Tolerable Upper Intake Levels (UL), and Acceptable Macronutrient Distribution Ranges (AMDR).

False.

Answer:
Deoxygenated blood enters the right atrium from the superior and inferior vena cava > The blood flows through the tricuspid valve into the right ventricle >From the right ventricle, the blood flows through the pulmonary valve into the pulmonary artery > The right and left pulmonary arteries carry deoxygenated blood to the right and left lungs for gas exchange > The blood releases carbon dioxide as waste and picks up a fresh supply of oxygen > The oxygenated blood flows through the pulmonary veins from the lungs into the left atrium > From the left atrium, the blood flows through the bicuspid, or mitral valve into the left ventricle > Left ventricular contraction forces blood through the aortic valve into the aorta for distribution to the systemic circulation
Explanation:
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.
