  2. Sensory Perception • Sensory Reception • Exteroreceptors • Interoreceptors • Sensory Transduction • Receptor Potential • Amplification • Transmission • Integration • Sensory adaptation

  3. Sensory Receptors • Mechanoreceptors • Touch • Hair cells • Pain receptors (nociceptors) • Thermoreceptors • Chemoreceptors • Gustatory • Olfactory • Electromagnetic receptors

  4. Vision • Photoreceptors • Planarians: eye cup • Invertebrates • Compound eyes • Ommatidia • Single-lens eye • Vertebrates • Single-lens eye

  5. Vertebrate Eye • Sclera • Choroid • Conjunctiva • Cornea • Iris • Pupil • Retina • Lens and Ciliary Body • Rods and Cones

  6. Outer ear External Pinna and Auditory canal Middle ear 3 ossicles Malleus Incus Stapes Oval Window Eustachian tubes Inner ear Cochlea Upper Vestibular Canal Lower Tympanic Canal Organ of Corti Auditory nerve Equilibrium Utricle Saccule Semicircular canals Hearing

  7. Skeletal System • Types • Hydrostatic • Exoskeleton • Endoskeleton • Types of Joints • Ball-and-socket • Hinge • Pivot
