Document Summary
With vision, it provides information about distant events, as does the sense of smell, which can tell us about sources of aromatic molecules far upwind. y body senses are closely tied to our own movements. Information from specialized organs in the inner ear and from receptors in the muscles and joints is actually produced by our own movements. This information helps us maintain our balance as we engage in our everyday activities. They release chemical transmitter substances that stimulate other neurons, thus altering the rate of firing of their axons. y. In somatosenses ( body senses ), dendrites of neurons respond directly to physical stimuli without the intervention of specialized receptor cells. However, some of these neurons do have specialized endings that enable them to respond to particular kinds of sensory information. sensory coding y nerves are bundles of axons which can do no more than transmit action potentials.
