The configuration of the different types of receptors working in concert in human skin results in a very refined sense of touch. e - Cochlear branch of CN VIII (vestibulocochlear nerve) b. spiral organ. __________ of the eye is receded into the orbit. Localization and sensitivity are easily determined in a __________ receptive field. (Consider that the deep pressure that reaches those deeper receptors would not need to be finely localized.) Note that these warmth detectors are situated deeper in the skin than are the cold detectors. Figure3. Determine the angle that the transmission axis of the polarizing sheet makes with the horizontal. Stretch receptors are found at various sites in the digestive and urinary systems. The points could then be moved closer and re-tested until the subject reports feeling only one point, and the size of the receptive field of a single receptor could be estimated from that distance. This redesigned and updated new edition offers a comprehensive introductory survey of basic clinical health care skills for learners entering health care programs or for those that think they may be interested in pursuing a career in health care.
