Document Summary
Receptors distributed over a large part of the body. Types of receptors that create the initial depolarization and an action potential. Mechanoreceptors: compression, bending, stretching of cells; touch, pressure, proprioception (using sensory info to better our movements), hearing, and balance; like the mechanically gated ion channels. Thermoreceptors: respond to changes in temperature; on skin or inside of the body. Photoreceptors: respond to light; vision; in our retina. Nocireceptors: extreme mechanical, chemical or thermal stimuli; pain; would be triggered when something is damaging our body. Lined almost completely by bone, areas that are not are found in the back that enter into the throat and the front where we have our actual nose (cartilage from top to tip of the nose) Openings are your nostrils or nares (naris singular) where air enters the nasal cavity. Right and left nasal cavities are separated by a septum but both come together at the back of the throat.
