Document Summary
Types of sensory receptors: there are 2 groups, general senses receptors are not specific to one region of the body and can be found in various places in the body. Smell (nose), taste (tongue), sight (in the eyes), hearing and balance (both of which are found in the ears). Types of senses (3: all of these receptors responsible for making a gp, eventually making an ap, mechanoreceptors (similar to mechanical-gated channels): compression, bending, stretching of cells. Touch, pressure, proprioception, hearing, and balance: chemoreceptors: chemicals become attached to receptors on their membranes (similar to ligand-gated ion channels). Nasal cavity: nasal cavity can be divided into two spaces: right and left nasal cavities, separated by a septum. There are ridges that help circulate air to prevent debris from entering the lungs. Then, information is carried to the olfactory tract to the brain: there are 14 bones that make up the nasal cavity.
