Parts Whole ● AUDITORY SYSTEM: o Pathway of sound sound pinna auditory canal eardrum (tympanic membrane) hammer, anvil, stirrup (HAS) oval window cochlea auditory nerve temporal lobes o Outer Ear pinna (ear, auditory canal o Middle Ear ear drum , HAS (bones vibrate to send signal) o Inner Earcochlea – like COCHELLA (sounds st processed here) ● THEORIES OF HEARING both occur in the cochlea o Place theory – location where hair cells bends determines sound (high pitches) o Frequency theory – rate at which action potentials are sent determines sound (low pitches OTHER SENSES: o Touch Mechanoreceptors spinal cord thalamus somatosensory cortex o Pain Gate-control theory we have agate to control how much pain is experienced o Kinesthetic: Sense of body position o Vestibular: Sense of balance (semicircular canals in the inner ear affect this) o Taste (gustation): 5 taste receptors: bitter, salty, sweet, sour, umami (savory) o Smell (olfaction): Only sense that does NOT route through the thalamus 1st.
