Compare and contrast the signaling events involved with the second messengers cAMP and IP3.
CHAPTER 6 What is the difference between sensation and perception • Sensation Message coming from senses, process that stimulation of sensory receptors, results in neural impulses to the brain. • Perception The brains interpretation of that message. Process of giving meaning to the message. What are the general functions of our sensory systems • The general functions of our sensory system are to detect certain forms of environmental energy, encode this information to action potential, and then relay information into brain or central nervous system. What is transduction Where does it take place Transduction: Converts incoming energy in the eye into patterns of action potentials or neural impulses. Translates information about that energy into a form that the brain can understand. What are sensory receptors What do they do What is adaptation Sensory Receptorsspecialized cells that protect particular forms of stimuli in the environment. Respond best to changes in stimulation. Adaptationdecreased response of sensory receptors to unchanging stimulation over time. What are wavelength, frequency, and amplitude How do they affect our perception of light and sound (color, brightness, pitch, loudness) • Wavelength the distance between the two peaks (related to color). • Frequency waves per unit of time (pitch) • Amplitude height (brightness) • Shorter wavelength=higher frequency b▯ lueish colors, highpitched sounds • Longer
