BIOL 3755 Lecture Notes - Lecture 10: Thermoreceptor, Membrane Potential, Melanopsin
Document Summary
Chapter 7: stimulus as physical energy sensory receptor (acts as transducer) Intracellular signal usually change in membrane potential. Sensory receptors: chemoreceptors, mechanoreceptors, photoreceptors, thermoreceptors. Info is integrated with sensory info coming from proprioceptors. Chemical senses: external chemicals binding to specific chemoreceptors are responsible for detection og taste and smell. Somatic sensation: sensation from skin, skeletal muscles, bones, tendons, and joints, activation of somatic receptors gives rise to sensations of, touch and pressure, awareness of position of body and movement, temperature, pain. Itch transduction and signaling overlap in complex ways with nociceptor mechanisms. Summary: general properties of sensory systems, somatic senses, chemoreception smell and taste, * ear, hearing and equilibrium, air to liquid, ** eye and vision.
