Elza [17]

Answer:

c. tinnitus

Explanation:

Tinnitus (a hearing impairment) is a form of  hearing of sound when no external sound is present Which is often described as a Ringing,Tinnitus may also sound like a clicking or roaring. i.e usually unclear voices or music are heard. The sound may be soft or loud, low or high pitched, and appear to be coming from one or both ears. Ranging from one person to another, the sound may causes depression or anxiety and can interfere with concentration.

Otitis externa is a condition that causes inflammation , the inflammation also covers  (redness and swelling) of the external ear canal, i.e the tube between the outer ear and eardrum.

Meniere's disease popularly called (MD), is a disorder of the inner ear that is characterized by episodes of feeling like the world is spinning (vertigo), hearing loss, and a fullness in the  ear. The cause of MD involves both genetic and environmental factors. Some of the factors include constrictions in blood vessels, viral infections, and autoimmune reactions.

Otosclerosis is a condition where one or more foci of irregularly laid spongy bone replace part of normally dense enchondral layer of bony otic capsule in the bony labyrinth. This condition affects one of the ossicles (the stapes) resulting in hearing loss, vertigo or a combination of symptoms.

Therefore from the foregoing we can conclude that Tinnitus is the correct anwser.

Excitatory neurotransmitters influence the receiving neuron to _____, whereas inhibitory neurotransmitters influence the receivi
Viktor [21]

Excitatory neurotransmitters cause the neuron to fire, and Inhibitory neurotransmitters cause the neuron not to fire.

Impulses are the signals passed from one neuron to another on the action of a stimulus. The impulses passed can be electrical or chemical. Neurotransmitters are the chemical molecules that help in the transfer of impulses between two neurons.

Chemicals like epinephrine, norepinephrine, and glutamate when released from the synaptic cleft of one neuron activate the receptors of other neurons, thereby initiating the other neuron to fire. These chemicals are called excitatory neurotransmitters.

Chemicals like GABA and glycine, when released from the synaptic cleft of one neuron do not activate the receptors of other neurons and hence the neurons will not fire the impulse. These chemicals are called inhibitory neurotransmitters.
