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:
1. dendrite = directs impulses toward the soma.
2. axon = conducts impulses toward the synaptic terminal.
3. perikaryon = region surrounding nucleus.
4. collateral branches = main branches of an axon.
5. synaptic terminal = enlarged end of an axon.
6. synaptic vesicles = contains neurotransmitters.
7. axon hillock = connects the cell body and axon.
8. Nissl bodies = clusters of RER and free ribosomes.
9. telodendria = fine branches of an axon.
10. myelinated internode = part of axon covered by Schwann cell.
11. neurilemma = Schwann cell's plasma membrane.
12. axolemma = membrane of the axon.
13. astrocyte = Forms the blood-brain barrier.
14. cell body = soma.
Answer:
it's C (ultrasound)
Explanation:
it's not cochlear implant because cochlear is for your ears
it's not laser light because laser light surgery is used to repair skin
brachytherapy is used for cancer treatment (usually prostate)
electrical impedance tomography is used to form a tomographic image
ultrasound therapy is used to reduce swelling
so it's ultrasound (C)
Answer:
They are altered by the many changes that happen during a womans bodying during pregnancy, which can change the distribution, adsorption, metabolism and excretion of drugs, therefore impacting their pharmacodynamic properties during pregnancy.
