In an attempt to differentiate between nociceptive group IV muscle receptors and “ergoceptive” ones, the discharges of single group IV fibres from skeletal muscle in response to local pressure, sustained stretch, repetitive contraction and intra-arterial injections of bradykinin, 5-hydroxytryptamine (5-HT), potassium, phosphate, and lactate were studied in anaesthetized cats. Of the 75 fibres of the study, 5 units were activated by sustained stretch, the responses occurring with a delay. These… CONTINUE READING
