CVP Exam 3 (pt.5)

Front

What are Olfactory Neurons

Back

neurons that sense a change in chemical NRG

Front

Structures ppl lack that result in poor smell

(why don't humans smell very well)

Back

• People have:

• - small olfactory bulbs

• - less nuerons in olfactory system

• - fewer functioning olfactory receptors

• - less transducing cells (olfactory nuerons)

Front

What does it mean that ppl have small olfactory bulbs

Back

indicates this sense is not important for ppl

Front

cranial nerves

Back

FILL IN LATER

Front

What three cranial nerves are we looking at in this class

Back

• - the first

• - the second

• - the eighth

• cranial nerves

Front

What is each cranial nerve in charge of?

Back

first cranial nerve: olfaction

second cranial nerve: vision

eighth cranial nerve: special mechanical sense

Front

Why don't ppl rely on sense of smell

Back

• 1. ppl r bipedal

(too far from ground that has lots of odor, air has little odor)

• 2. ppl don't sniff deeply very often

(we don't smell e/o like dogs, we rely more on vision/touch)

Front

What is the Vomeronasal Sense

Back

an accessory olfactory bulb <- a specialized system inside the olfactory system

(Not a part of the olfactory bulb)

divisions of a cranial nerve passes through this olfactory bulb

it is our "special sense of smell"

Front

How does Vomeronasal Sense Function

Back

vomeronasal system + its receptors:

change shape in response to diff odors, specifically pheromones

Front

How big is the vomeronasal sense in ppl

Back

small
