BIO271H1 Lecture : Lecture 4
Document Summary
trp chanels: transient receptor potential channels, mechanosensory protein receptors. channels are linked to extracellular matrix and to the cytoskeleton. receptors that detect touch, pressure, and vibration. receptor structure: some are free nerve endings. In some the nerve endings are enclosed in accessory structures: free nerve endings and merkel"s disks, eg. muscle spindles: located in skeletal muscles, monitor muscle length. golgi tendon organs: located in tendons, monitor tendon tension. Joint capsule receptors: located in capsules that enclose joints, monitor pressure, tension, and movement. Insect tactile receptors www. notesolution. com: two common types of sensila: trichoid: hairlike projection of cuticle, bipolar sensory neuron, trp channel. Interconnected bones in air-filled cavity: inner ear. series of fluid-filled membranous sacs and canals. the inner ears of most mammals are very similar, it is: mammalian ear the outer ears (pinna) that differ significantly, mechanoreceptors are present in the vestibular canal and in the cochlea.
