This chapter distinguish between the following pairs of terms: sensation and perception; sensory transduction and receptor potential; tastants and odorants; rod and cone cells; oxidative and glycolytic muscle fibers; slow-twitch and fast-twitch muscle fibers; endoskeleton and exoskeleton. | What is the function of: Cone cells? Rod cells? The perceived pitch of a sound is dependent on ? What is the difference between perception and sensation? What is the function of: Cone cells? Color Rod cells? Light The perceived pitch of a sound is dependent on ? wavelength (λ) What is the difference between perception and sensation? Chapter 50 Campbell Biology – 9th Edition The location and function of several types of sensory receptors How skeletal muscles contract Cellular events that lead to muscle contraction Mechanoreceptors: physical stimuli – pressure, touch, stretch, motion, sound Thermoreceptors: detect heat/cold Chemoreceptors: transmit solute conc. info – taste (gustatory), smell (olfactory) Electromagnetic receptors: detect EM energy – light (photoreceptors), electricity, magnetism Pain receptors: respond to excess heat, pressure, chemicals This rattlesnake and other pit vipers have a pair of infrared receptors, one between each eye and nostril. The organs are sensitive enough to detect the infrared radiation emitted by a warm mouse a meter away. Eye Infrared receptor Some migrating animals, such as these beluga whales, apparently sense Earth’s magnetic field and use the information, along with other cues, for orientation. Reception: receptor detects a stimulus Sensation = action potentials reach brain via sensory neurons Perception: information processed in brain Outer ear Middle ear Inner ear Pinna Auditory canal Tympanic membrane Eustachian tube Middle ear Stapes Incus Malleus Skull bones Semicircular canals Auditory nerve, to brain Tympanic membrane Oval window Round window Cochlea Eustachian tube Auditory nerve Tympanic canal Cochlea duct Organ of Corti Vestibular canal Bone To auditory nerve Axons of sensory neurons Basilar membrane Hair cells Tectorial membrane Semicircular canals Flow of endolymph Vestibular nerve Nerve fibers Vestibule Utricle Saccule Ampulla Flow of endolymph Cupula Body movement Hairs Hair cell Cornea Ciliary body . | What is the function of: Cone cells?
