Paper details The purpose of this assignment is to investigate the media’s effect on sexual behavior and attitudes. You may choose any single media form (print ads, social media ads, music, commercials, cartoons, TV shows, etc.). This assignment is not meant to analyze any individual’s personal media postings (Facebook, Instagram, Twitter, etc.) but rather companies or businesses who are marketing products

Paper details QUESTION 1
Which of the following statements is TRUE?

Each rods communicates with one bipolar cell

Olfactory cells extend into the olfactory bulb

Taste cells extend from taste buds to the brainstem

Olfactory acuity (strong sense of smell) is inversely proportional to the surface area of olfactory epithelium

QUESTION 2
Which of the following is true?

Schwann cells provide myelination throughout the CNS

Saltatory conduction is the amount of sodium needed to propagate/conduct an action potential

Myelin helps to prevent/slow repolarization

All neurons are myelinated

Gaps in the myelin (Nodes of Ranvier) prevent ion flow across the membrane

– 1. 2. 3. 4. 5.
Effector organ

– 1. 2. 3. 4. 5.
Receptor

– 1. 2. 3. 4. 5.
Efferent neuron

– 1. 2. 3. 4. 5.

QUESTION 5
Which of the following about sound is TRUE?

Sound receptors lie within the Organ of Corti along the base of the cochlea

Stereocilia depolarize each time they are tugged by vibrations in the membrane their tips are attached to (tectoral membrane)

High frequency (high pitched) sounds preferentially cause vibrations in the apex of the cochlea

Air movements travel (blow up) the cochlea causing vibration in the mechanoreceptor stereocilia embedded in the basilar membrane

QUESTION 14
Which of the following is false?

During repolarization voltage gated potassium channels are open

Voltage gated sodium channels are open if a neurons membrane potential is less than -55 mV

Potential changes less than the threshold potential are called graded potentials

The size of an action potential depends on the number of sodium channels open
