Select all that apply. Group of answer choices Merkel disc Meissner’s corpuscle Langerhans cell Pacinian corpuscle
- 1-Which is the LAST part of the retina that a photon passes through before it is captured by an opsin protein? Photoreceptor inner segment Photoreceptor outer segment Bipolar cell layer 2-Ganglion cell layer Visual information travels down the optic nerve first to the ____________ and from there to the primary visual area V1. Medical geniculate nucleus of the thalamus Lateral geniculate nucleus of the thalamus Hippocampus 3- Glomerulus The combined response of the three opsins in cone cells (S, M, and L) produces a relatively unique signal for each wavelength of light in the visible spectrum. This supports the __________ theory of color vision. Trichromatic Color-opponent Electromagnetic 4-Gestalt As you move from V1 to V5 and higher visual centers, receptive fields of individual neurons as indicated by "preferred stimuli" get: More simple More complicated More grandmother-like More surround inhibitionMany diabetic patients are warned by their doctors to test their glucose levels by pricking the sides of their fingers rather than the pads. Pricking the sides avoids stimulating which receptor? Krause end bulbs Meissner’s corpuscles Ruffini ending NociceptorsFigure 36.5 Which of the following statements about mechanoreceptors is false? Pacini corpuscles are found in both glabrous and hairy skin. Merkel’s disks are abundant on the fingertips and lips. Ruffini endings are encapsulated mechanoreceptors.

- What type of receptor cell is responsible for transducing pain stimuli? mechanoreceptor nociceptor osmoreceptor photoreceptorWatch this video (http://openstaxcollege.org/l/2point) to see a quick demonstration of two-point discrimination. Touching a specialized caliper to the surface of the skin will measure the distance between two points that are perceived as distinct stimuli versus a single stimulus. The patient keeps their eyes closed while the examiner switches between using both points of the caliper or just one. The patient then must indicate whether one or two stimuli are in contact with the skin. Why is the distance between the caliper points closer on the fingertips as opposed to the palm of the hand? And what do you think the distance would be on the arm, or the shoulder?The middle ear functions in__________. a. detecting shifts in body position b. transmitting sound waves c. sorting sound waves out by frequency d. all of the above
