WebJul 19, 2024 · Functionally, mechanoreceptors can be thought of as dendrites for sensory neurons. Slowly adapting receptors include Merkel's discs and Ruffini endings. Rapidly adapting receptors include Hair follicle receptors, Pacinian corpuscles, and Meissner's corpuscles. Location of receptors depends on function. Specifically, Free nerve endings, … WebD. Exteroreceptors are sensory receptors that respond to stimuli from outside the body. Examples include cutaneous receptors, which respond to touch, and special senses, such as smell and taste. When the exteroreceptor is stimulated, it triggers an action potential that is then transmitted to the brain, allowing us to perceive these sensations.
Web1) free nerve endings- simple receptors, sense itching and other sensation. 2) Tactile (meissner's) corpuscles- detect fine touch and texture, distinguish between two points on skin. 3) lamellate (Pacinain) corpuscles- common in deeper subcutaneous tissues, tendons and ligaments, detect heavy pressure and vibrations. describe thermoreceptors. WebTable 8–1 provides a list of the principle sensory modalities. Sensory receptors convert specific forms of energy into action potentials in sensory neurons.
