PSYB51H3 Chapter Notes - Chapter 13: Lamellar Corpuscle, Axon, Posterior Grey Column
Document Summary
Kinesthesia: perception of the position and movement of our limbs in space. Somatosensation: collectively, sensory signals from the skin, muscles, tendons, joints, and internal receptors. Epidermis: the outer of two major layers of skin. Dermis: the inner of two major layers of skin, consisting of nutritive and connective tissues, within which lie the mechanoreceptors. Mechanoreceptor: a sensory receptor that responds to mechanical stimulation (pressure, vibration, or movement) A-beta fiber: a wide-diameter, myelinated sensory nerve fiber that transmits signals from mechanical stimulation. Meissner corpuscle: a specialized nerve ending associated with fast-adapting (fa: fibers that have small receptive fields. Merkel cell neurite complex: a specialized nerve ending associated with slowly adapting (sa i) fibers that have small receptive fields. Pacinian corpuscle: a specialized nerve ending associated with fast-adapting (fa. Ruffini ending: a specialized nerve ending associated with slowly adapting (sa ii) fibers that have large receptive fields. Thermoreceptor: a sensory receptor that signals information about changes in skin temperature.
