Document Summary
In theory, we have too many senses to quantify. Generally speaking, we have nine senses 5 special senses (vision, hearing, taste, smell, equilibrium) and 4 somatic senses (touch, temperature, proprioception, nociception). We are usually partly conscious of sensory data from these senses, but largely unconscious of other sensory data for viscera and internal homeostasis. The senses carry information about the body and surroundings to the cns. Five special senses: vision, hearing, equilibrium, taste, smell. Four somatic senses: touch, temperature, proprioception, nociception (i. e. , pain and itch) We are usually at least partly conscious of data from these nine senses, but largely unconscious of other sense data such as blood pressure, lung inflation, blood-glucose concentration, internal body temperature, ph, etc. Receptors are cells which may or may not be neurons, and which convert stimuli (e. g. , light, sound, etc. ) into electrical signals: signal transduction: the process of conversion of stimuli into electrical signals.
