<prompt> Which of the following receptors mediate stretch reflex:Golgi tendon organMerkels discMuscle spindleMeissners corpuscles  <response>: Muscle spindle are distributed throughout the belly of muscle send information to Nervous system about i Muscle length ii Rate of change of muscle length Golgi tendon organ is located in muscle tendons transmits information about i Tendon tension ii Rate of change of Tendon tension Muscle stretch Intrafusal fibers of muscle spindles stretched Signal from muscle spindles receptor Ia afferents Enter spinal cord end on a motor neuron a motor neuron carries efferent to extrafusal fibers Brief contraction stretch reflex Monosynaptic MEISNER CORPUSCLE - Present in non-hairy pas of skin Finger tips, lips etc. and other areas where ability to discern spatial locations of touch sensation are highly developed - They adapt in fraction of a second after stimulation hence are paicularly sensitive to movement of objects over skin surface as well as low frequency vibrations MERKELS DISC - Expanded tip tactile receptors - Transmit an initially strong but paially adapting similar then continuing weaker signal that adapt slowly - Determine continuous touch of objects against skin
