Chapter 10: Sensory Systems Quiz
The sensory system is mainly made up of the organs that help in human sense. We have five sensory organs, which include the ears, tongue, skin, nose and eyes and they have receptors that relay information through sensory neurons to the appropriate places within the nervous system. Test out what you recall from chapter 10 on the sensory system by taking up the quiz below on the topic. All the best!
- 1.The mechanism by which a receptor converts a stimulus into an electrical signal is called
- A.
Conduction
- B.
Convection
- C.
Transduction
- D.
Modulation
- E.
Propagation
- 2.Which of the following best illustrates the concept of an adequate stimulus?
- A.
When a boxer gets punched in the eye, he perceives light
- B.
Rotation of the head stimulates certain receptors in the vestibular system but not those in the visual system
- C.
Information from different photoreceptors converges on a single ganglion cell that projects to the lateral geniculate nucleus.
- D.
Hair cells in the cochlea are stimulated by sound vibrations over a wide range of frequencies
- 3.The ability to perceive different frequencies in sound vibrations is based on the fact that
- A.
The stereocilia of any given hair cell respond to one frequency only
- B.
Different areas of the basilar membrane resonate at different frequencies such that a sound of a particular frequency causes only a certain region of the membrane to vibrate
- C.
The frequency of action potentials in the cochlear nerve varies in proportion to the frequency of a sound stimulus
- 4.The stereocilia for hearing are exposed to
- A.
Endolymph in the vestibular duct
- B.
Perilymph in the vestibular duct
- C.
Endolymph in the cochlear duct
- D.
Perilymph in the cochlear duct
- E.
Endolymph in the tympanic duct
- 5.The parasympathetic nervous system causes
- A.
Contraction of the radial muscle of the iris
- B.
Contraction of the ciliary muscle
- C.
Pupillary dialation
- D.
A and c
- E.
All of the above
