to watch an animation of the events that occur when a hormone binds to a cell membrane receptor.
A small molecule binds to a G protein, preventing its activation. What direct effect will this have on
signaling that involves cAMP? ✔Correct Answer-2. Adenylyl cyclase will not be activated.
to watch an animation showing the role of the hypothalamus and the pituitary gland. Which
hormone is released by the pituitary to stimulate the thyroid gland? ✔Correct Answer-thyrotropin
to view an animation describing the location and function of the adrenal glands. Which hormone
produced by the adrenal glands is responsible for mobilization of energy stores? ✔Correct Answer-
cortisol
to view an animation describing the function of the hormone melatonin. What should you avoid
doing in the middle of your sleep cycle that would lower melatonin? ✔Correct Answer-turning on
the lights
to view an animation describing the location and function of the pancreas. What goes wrong in the
function of insulin in type 2 diabetes? ✔Correct Answer-the cells don't respond to insulin like they
should
to learn more about how the structures of the ear convert sound waves into a neural signal by
moving the "hairs," or stereocilia, of the cochlear duct. Specific locations along the length of the duct
encode specific frequencies, or pitches. The brain interprets the meaning of the sounds we hear as
music, speech, noise, etc. Which ear structures are responsible for the amplification and transfer of
sound from the external ear to the inner ear? ✔Correct Answer-The ossicles
to learn more about the inner ear and to see the cochlea unroll, with the base at the back of the
image and the apex at the front. Specific wavelengths of sound cause specific regions of the basilar
membrane to vibrate, much like the keys of a piano produce sound at different frequencies. Based on
the animation, where do frequencies—from high to low pitches—cause activity in the hair cells
within the cochlear duct? ✔Correct Answer-the apex of the cochlea
between the base and the apex of the cochlea
to learn more about a transverse section through the brain that depicts the visual pathway from the
eye to the occipital cortex. The first half of the pathway is the projection from the RGCs through the
optic nerve to the lateral geniculate nucleus in the thalamus on either side. This first fiber in the
pathway synapses on a thalamic cell that then projects to the visual cortex in the occipital lobe
where "seeing," or visual perception, takes place. This video gives an abbreviated overview of the
visual system by concentrating on the pathway from the eyes to the occipital lobe. Specialized cells in
the retina called ganglion cells convert the light rays into ________________. ✔Correct Answer-
electrical signals
to learn more about how the brain perceives 3-D motion. Similar to how retinal disparity offers 3-D
moviegoers a way to extract 3-D information from the two-dimensional visual field projected onto
the retina, the brain can extract information about movement in space by comparing what the two
eyes see. If movement of a visual stimulus is leftward in one eye and rightward in the opposite eye,
