Chapter 15 The Special Senses
- Why does inhaling deeply and slowly through the nose help to identify an odor?
- More air containing the odor is brought into contact with the olfactory epithelium.
- Impulses originate slowly in the olfactory epithelium.
- The tissue needs more time in contact with the odor.
- Threshold for odor detection is high.
- Receptors in the olfactory epithelium are highly specific.
- Sensory structures that detect taste are
- palates.
- papillae.
- taste buds.
- ciliary membranes.
- thermoreceptors.
- Some thyroid disorders are characterized by an increase in the width of the palpebral fissure. This would be an increase in the distance between the
- eyebrows.
- eyelashes.
- eyelids.
- eyes.
- lacrimal glands.
- Which of the following cranial nerves innervates an eye muscle?
- optic
- facial
- abducens
- trigeminal
- vagus
- Blood vessels enter the eye and nerve processes exit the eye at the
- optic disc.
- macula lutea.
- sensory retina.
- fovea centralis.
- pupil.
- For distant vision,
- the lens is more spherical.
- the suspensory ligaments relax.
- the ciliary muscles are relaxed.
- light is refracted more by the lens than by the humors.
- the lens is thickened.
- When rhodopsin is exposed to light,
- more rhodopsin is formed.
- retinal separates from opsin.
- the cones generate action potentials.
- free retinal is converted to vitamin A.
- retinal becomes more attached to opsin.
- A person loses all vision in their left eye. One possible cause could be damage to the
- optic chiasma.
- left optic tract.
- optic nerve in the left eye.
- right lateral geniculate nucleus.
- right visual cortex in the occipital lobe.
- Damage to the vestibulocochlear nerve would result in some loss of
- hearing and balance.
- hearing and taste.
- smell.
- taste.
- hearing and sight.

Chapter 16 Autonomic Nervous System
- If a somatic sensory neuron is impaired, which of the following is most likely to occur?
- loss of muscle tone
- loss of proprioception
- paralysis
- death
- tetanus
- Chain ganglia are part of the
- central nervous system.
- sympathetic branch of the ANS.
- somatic motor branch of the ANS.
- parasympathetic branch of the ANS.
- spinal cord.
- The membranes of all postganglionic neurons in autonomic ganglia have
- somatotrophic receptors.
- muscarinic receptors.
- adrenergic receptors.
- nicotinic receptors.
- macrotinic receptors.
- Autonomic reflexes
- are impossible.
- are integrated somewhere in the CNS.
- have efferent input and afferent output.
- are an example of positive feedback.
- are harmful.
- Which of the following is NOT a parasympathetic effect?
- constriction of the pupils of the eye
- contraction of the urinary bladder
- decreased heart rate
- dilation of the bronchioles in the lungs
- increased gastric secretions
