Sensory receptor in skin and muscle

The phrase "sensory receptor in skin and muscle" refers collectively to several classes of specialized cells or neuronal endings that detect physical stimuli such as touch, pressure, vibration, temperature changes, pain signals from tissue damage (nociception), stretch within muscles/tendons/joints (proprioception), etc.[4] These include mechanoreceptors like Merkel cells/discs, Meissner’s corpuscles/tactile corpuscles for light touch; Pacinian corpuscles/lamellated corpuscles for deep pressure/vibration; Ruffini endings/bulbous corpuscles for stretch detection; free nerve endings serving as both thermoreceptors and nociceptors throughout the dermis/epidermis/hair follicles/joint capsules/muscle spindles/Golgi tendon organs.[6] Each type has distinct anatomical locations within layers of the skin or embedded within skeletal muscles/tendons/joints.[5] They function by converting external physical forces into electrical signals transmitted via primary afferent neurons toward the central nervous system where they are interpreted as various sensations essential to survival—such as detecting harmful heat/cold/painful stimuli—or enabling fine motor control through proprioceptive feedback.[6] This term should be replaced with more precise names when possible—for example “Meissner’s corpuscle,” “muscle spindle,” “TRPV1-expressing nociceptive neuron,” etc.—to enable meaningful scientific discussion about structure-function relationships or pharmacological targeting strategies relevant to human health/disease contexts.[3]

Varies by drug/receptor subtype: – Blockade of action potential propagation via sodium channel inhibition. – Desensitization or activation-induced degeneration of specific nerve terminals. – Modulation of calcium influx affecting neurotransmitter release. No universal mechanism applies to all these diverse sensory receptors.
