Exam 16: Nervous System: Senses

The reason we can detect so many different odors is that each olfactory neuron is slightly different from the others,allowing for a wide range of odor sensations.

Where would you find olfactory hairs

These receptors detect changes in pressure within the body caused by the stretch or distention of internal structures.

The classification of a receptor as a photoreceptor or a mechanoreceptor depends on

The "dark current" of photoreceptors refers to

These receptors detect specific molecules in our external and internal environments.

What is the correct sequence for lacrimal fluid production and drainage A: Tears disperse across the surface of the eye. B: Tears are produced by the lacrimal gland. C: Fluid drains through the nasolacrimal duct. D: Fluid enters the nasal cavity. E: Fluid enters the lacrimal canaliculi and collects in the lacrimal sac.

These receptors respond to pain caused by external and internal stimuli.

Stimulation of olfactory receptor cells involves activation of G-protein molecules inside them.

The entire area through which the sensitive ends of the receptor cells are distributed is the
