Document Summary
Receptor receives signal, causes depolarization, ap sent to brain. There are different receptors used for us to get an action potential. Touch, pressure, proprioception (gather sensory info about muscles and joints about position), hearing and balance. Physical open a gated channel (like mechanically-gated channels) These bind to a protein on the membrane. Wouldn"t be triggered by a normal temperature, would be triggered by something extreme like burning - that"s how our brain differs between normal and extreme situations. 9 different bones on each side, 14 bones on total (because some bones are shared by each side) Only places without bone - the back and the front. Top of nose to tip of nose - cartilage. Nostrils aka nares - openings where the air moves into nasal passage. The nasal cavities are separated by a septum, they come back together at the back of your throat. Create turbulent air flow, to get rid of debris.
