Which fluid-filled chambers and canals make up a vestibular labyrinth on one side of the head?
The semicircular canals, the utricle, and the macula
The cochlea, the cupula, and the Crista
The anterior, posterior, and lateral otolith organs and semicircular canals
Two otolith organs and three semicircular canals
Which of the following are involved in flavour perception?
Gustation and olfaction
Gustation and vision
Vision, touch, and olfaction
All of these.
The best explanation for the perceived intensity of a smell decreasing after continuous exposure is:
Partial anosmia
Ofour modification
Odour blindness
Adaptation
Olfactory receptor cells are renewed:
Every 8 months
Every 8 days
Every 8 hours
Every 8 weeks
The contact of a water drop on the hand can be sensed about half a second before its temperature because:
The lemniscal pathway has myelinated axons; the spinothalamic tract does not
Signals have faster conduction velocities in the spinothalamic tract than in the lemniscal pathway
Temperature signals are delayed by branching projections to the spinal cord that mediate relfex actions
Axons associated with free nerve endings are myelinated; those associated with mechanoreceptors are unmyelinated
Which statement about cortical topographic maps of somatosensory space is false?
Moving over the somatosensory cortex from left to right ear systematically maps the right then left sides of the body
In humans, the part of the map representing the hands contains cells with small receptive fields
In humans, a relatively large area of the map contains cells with receptive fields on the face
A vertical column of cortical cells systematically maps the whole body
