Transient receptor potential (TRP) ion channel Respond to temp Mechanoreceptors - Touch Mechanoreceptors - Touch • Examples of touch receptors: • Hair follicle receptors • Meissner corpuscles • Pacinian corpuscles • Ruffini corpuscles • Merkel’s disks (just know there’s different types) Proprioceptors & Baroreceptors ( mechanoreceptors )
Proprioceptors o Monitor the position and movement of the body o Muscle Tension Muscle spindles Golgi tendon organs Baroreceptors o Monitor blood pressure o Blood pressure Carotid sinus Aortic arch Sound Detection Aquatic vs terrestrial sound Aquatic vs Terrestrial Hearing structures o Fish hearing structures are otoliths Denser than water and allows fish to detect sound o Human ears are Outer, middle, inner ear Inner = sound waves Outer/middle = convert sound waves into motion of solid structures and transfer that motion to the liquid of the inner ear Sound waves first strike the tympanic membrane which transfers the vibrations to the bones of the middle ear The last bone vibrates the oval window which transfers sound into the inner ear
Transduction – The Cochlea Pressure waves are converted to pressure waves that travel through the fluid of the… Cochlear duct then strikes the… Organ of corti which is made of several structures o
