sensation + sense organ quiz

what receptor reacts to chemical stimuli such as odour, taste, co2 levels, o2 levels...

• proprioceptors

• chemoreceptor

• thermoreceptor

• mechanoreceptor

what receptor is stimulated in response to pain?

• nociceptors

• photoreceptors

• mechaoreceptor

• thermoreceptor

what is "fast" pain?

• reffered pain

• sharp, localzied pain

• dull, aching pain

• nociceptors fire a quick stimulus in response to dull pain

what is "slow" pain?

• dull ache

• takes body a while to detect pain

• located deep within body organs or cavities

• localized throbbing

what is reffered pain?

• organ and skin receptors form a single pathway

• pain may be sensed on/in a different area of the body

• dull, aching pian present in multiple areas at once

• pain originates from a deep organ or cavity

Answer explanation

what is the correct order of the pain pathway?

• nociceptors detect stimuli, chemicals are secreted so that impulse travels to spinal cord, that is then conducted to brainstem and the cerebrum that then relays the signal to the medulla oblongata that produces a emotional response to pain

• injured tissues secrete histamine that stims nociceptors, neuron conducts impulse to brain stem, impulse travels to cerebrum, then limbic system that produces a emotional response to pain

• injured tissues secrete a chemical that stims nociceptors, neurons conduct the impulse to spine, singal travels to brain stem, cerebrum makes one aware of pain and signal then travels to hyopthalamus + limbic system that produces a emotional response to pain

what does the eustachian tube do?

• senses sound vibrations

• aids in balance and hearing

• connects to the nasopharynx and equalizes pressure

• is the organ of hearing

what is the cochlea?

• the structure needed for hearing

• a structure that contains a gel-like substance that helps indicate the position of the head

• a structure consisting of three small bones that connect the eardrum to the inner ear

• essential for balance

what is the ampulla?

• the outer cartilage of the ear

• the three bones that connect to the eardrum

• the organ needed for hearing

• a bulb-like structure that detects the direction of head movement

Answer explanation

what is dynamic equlibrium?

• involves the ampulla at the end of each cannal

• involves semicircular canals

• maintenance of proper head position in response to rotational / turning movements

• involves the vestibule
