Summary Introduction
Introduction:
The auditory canal of human ear contains small hair like structures that are called stereocilia. These sensory hairs move in response to a sound wave along with cupula and endolymph, and generate action potential by opening the potassium ion channels in the auditory nerves. The action potential is carried to the auditory cortex of brain.

- Which options are true regarding the gate control theory of pain? Select all that apply: a. Mechanoreceptor fibres synapse directly onto nociceptor fibres and potentiate incoming pain signals b. Mechanoreceptor fibres synapse onto interneurons, which synapse onto nociceptor fibres and potentiate incoming pain signals c. Applying a mechanical stimulus, such as grabbing the injured area, will soothe the injury d. Mechanoreceptor fibres synapse directly onto nociceptor fibres and inhibit incoming pain signals e. Mechanoreceptor fibres synapse onto interneurons, which synapse onto nociceptor fibres and inhibit incoming pain signals f. Applying a mechanical stimulus, such as grabbing the injured area, is a natural defensive reaction, but does little to actually affect incoming pain signals.arrow_forwardThe inner ear is responsible for both hearing and balance. One of the diseases affecting the inner ear is Meniere's disease. Affected individuals often experience vertigo, among other symptoms. Vertigo is a sensation that the surrounding is spinning or swaying in the absence of any body movement. Which of the following rows correctly identifies the affected structure and process in individuals experiencing vertigo? Select one: a. Structure Process Semicircular canals Rotational equilibrium b. Structure Process Semicircular canals Gravitational equilibrium c. Structure Process Organ of Corti Gravitational equilibrium d. Structure Process Organ of Corti Rotational equilibriumarrow_forwardEmergency room doctors often shine a light into the eyes of patients with potential trauma to the brain to test their pupillary reflex. This is an important method in determining possible damage in the following areas of the nervous system, EXCEPT the a. sensory neuron and motor neuron b. interneuron c. optic nerve and circular muscle of iris d. occipital lobearrow_forward
- Select the statement that explains the neural mechanism underlying the sensation of fast, sharp pain followed by delayed, longer-lasting pain after an injury. a. Fast pain is conducted by mechanoreceptors, whereas delayed pain is conducted by fibers with free nerve endings. b. Fast pain is conducted by free nerve endings in the dermis, whereas delayed pain is conducted by deep nerve endings in the subcutaneous layer. c. The receptive fields differ for the two types of pain sensation such that fast pain fibers have smaller receptive fields than the delayed pain fibers. d. Fast and delayed pain represent the progression of the injury; both are conducted by the same fibers. e. Fast, sharp pain is conducted by myelinated axons, whereas delayed, longer-lasting pain is carried by unmyelinated axons.arrow_forwardBenign Paroxysmal Positional Vertigo is a disorder where some of the calcium carbonate crystals in the utricle migrate into the semicircular canals. Why does this condition cause periods of dizziness? a. The hair cells in the semicircular canals will be constantly activated. b. The hair cells in the semicircular canals will now be stimulated by gravity. c. The utricle will no longer recognize acceleration. d. There will be too much volume in the semicircular canals for them to detect motion.arrow_forwardTristan accidentally touches a hot propane torch. He immediately withdraws his hand and then exclaims “ouch!” Why did Tristan exclaim “ouch!” after he had withdrawn his hand from the hot coffee? Select one: a. The threshold of the sensory receptor was exceeded and an action potential to the brain could not be triggered. b. The neural processing is faster through the spinal cord than the processing involving the brain. c. The sensory receptors in the fingers were damaged by the hot torch and were not able to send a fast signal to the brain. d. The hot torch triggered too many receptors and resulted in an excessive number of nerve impulses travelling to the brain. The brain was not able to process all the signals fast enough.arrow_forward
