Which of the following is NOT a preprioceptor?
root hair plexus
function in relation to movements and body position
True or False: Mechanoreceptors are activated by a change in temperature
True or False: Free nerve endings are the simplest, most common, and most widely distributed sensory receptors
True or False: Somatic sense receptors located in muscles and joints are called visceroreceptors
True or False: Golgi tendon receptors are stimulated by excessive muscle contraction
true of false: exteroceptors are often called cutaneous receptors because of their placement in the skin
olfactory receptors and taste buds are:
olfactory epithelium consists of
all of the above
all of the following are primary taste sensations except:
nerve impulses responsible for the sensation of taste are carried in all of the following cranial nerves except:
true or false: olfaction requires the chemical response of a dissolved substance for a stimulus
true or false: the olfactory receptor cells lie in an excellent position functionally to smell delicate odors
true or false: the transmission pathway for olfactory sensations is as follows: olfactory cilia, olfactory bulb, olfactory tract, thalamic, and olfactory center of the brain
true or false: the tip of the tongue reacts best to bitter taste
which of the following is a structure of the middle ear?
the auditory tube connects the
middle ear and the nasopharynx
the only structure of the inner ear concerned with hearing is the
dynamic equilibrium depends upon the functioning of the
the neuronal pathway of hearing begins at the
the passageway leading to the tympanic membrane is the
external auditory meatus
the sense organ(s) responsible for the sense of balance is/are located in the d
true or false: the membranous labyrinth is filled with endolymph
true or false: the correct order of the auditory ossicles from deep to the tympanic membrane is incus, malleus, and stapes
true or false: if the hairs of the organ of Corti are damaged, nerve deafness results--even if the vestibulocochlear nerve is healthy
true or false: movement of the tympanic membrane from sound waves initiates vibration of the auditory ossicles
true or false: vertigo essentially means "fear of heights"
from superficial to deep, the three layers of tissue that compose the eyeball are;
sclera, choroid, retina
the anterior portion of the sclera is called
the neurons of the retina (in the order in which they conduct impulses) are:
photoreceptor neurons, bipolar neurons, ganglion neurons
all of the axons of ganglion neurons extend back to an area of the posterior eyeball called the

true or false: all the muscles associated with the eye are smooth or involuntary
true of false: conjunctivitis is a highly contagious infection
true or false: the correct order of flow of tears is as follows: lacrimal gland, lacrimal duct, punctum, lacrimal canal, lacrimal sac, and nasolacrimal duct
true or false: deficiency of the blue-sensative photopigments is the most common form of color blindness
true or false: the opening and separation of opsin and retina in the presence of light is called bleaching
true or false: the retina is the incomplete innermost coat of the eyeball in that it has no anterior portion
true or false: refraction means "the deflection or bending of light rays"
true or false: a person with a 20/100 vision can see objects at 100 feet that a person with normal vision can see at 20 feet
