A&P Chapter 15: Special Senses

1. Which of these statements is not true with respect to olfaction?

• Olfactory sensation is relayed directly to the cerebral cortex without passing through the thalamus

• 1. Olfactory neurons are replaced about every 2 months

• 1. The olfactory cortex is involved in the conscious perception of small

• 1. The secondary olfactory areas are responsible for visceral and emotional reactions to odors

• 1. The olfactory cortex is in the occipital lobe of the cerebrum

Taste cells

• are found only on the tongue.

• 1. extend through tiny openings called taste buds.

• 1. have no axons but release neurotransmitters when stimulated.

• 1. have  axons  that  extend  directly  to  the  taste  area  of  the  cerebral  cortex.

The lens normally focuses light onto the

• Optic disc

• 1. Iris

• Macula

• Cornea

• Ciliary body

1. Given these structures: 

   1. (1)Lens

   2. (2)Aqueous humor

   3. (3)Vitreous humor

   4. (4)Cornea

   5. What of the following arrangements lists the structures in the order that light entering the eye encounters them.

1. Contraction of the smooth muscle in the ciliary body causes the

• lens to flatten

• 1. pupil to constrict.

• lens to become more spherical.

• pupil to dilate

1. Given these events:

   1. (1)Bipolar cells depolarize.

   2. (2)Glutamate  release  from  presynaptic  terminals  of  photoreceptor  cells decreases.

   3. (3)Light strikes photoreceptor cells.

   4. (4)Photoreceptor cells are depolarized.

   5. (5)Photoreceptor cells are hyperpolarized.

   6. Choose the arrangement that lists the correct order of events, starting with the photoreceptor cells in the resting, nonactivated state.

• 1,2,3,4,5

• 2,4,3,5,1

• 3,4,2,5,1

• 4,3,5,2,1

• 5,3,4,1,2
