Document Summary
Auditory cortex: frontal lobe, temporal and parietal lobes, temporal lobe. A conscious or subconscious awareness of changes in the external or internal conditions of the body. General senses: somatic and visceral, tactile, thermal, pain, proprioceptive (relative position of structures between one another, receptors are often only modified dendrites. Special senses: receptors are unique for function, distinct from one another, embedded within complex sensory organs, neural pathways are more. Olfactory receptors are first-order neurons in the olfactory epithelium: reside in upper surface of nasal passage, axons from cn 1 projects through cribiform plate ending in bulb, olfactory hairs (on dendrite) stimulated by odorants. Only sensation that reaches the cerebral cortex without synapsing in the thalamus. Olfactory pathway: olfactory receptor cells, cribriform, transmitting olfactory nerve, olfactory bulb of ci, olfactory tract of ci, primary olfactory area. Only five primary tastes: sour, sweet, bitter, salty, umami (the flavor you get from msg savoury but not salty)
