“…Similarly, in the metacarpophalangeal and interphalangeal joints of the human hand, Stilwell (1957) observed Ruffini but not Golgi-Mazzoni endings. If Golgi-Mazzoni endings are absent in human metacarpophalangeal and interphalangeal joint capsules then the slowly adapting responses to external pressure and angular displacement observed in the present study must be attributed to Ruffini endings.…”

SUMMARY1. Microneurographic techniques were employed to record unitary activity from afferents associated with digital joints of six conscious human subjects. Of 120 single afferents sampled from the median and ulnar nerves at the wrist, eighteen (15%) were classified as joint afferents; the majority of the sample (72-5%) were of cutaneous origin, and 12-5 % were from muscle spindles and tendon organs.

“…Ruffini-corpuscles or Ruffini-like endings have also been reported in hairy skin as well as in joint capsules of other mammals (Stilwell, 1957;Polacek, 1966;Halata, 1977;Sathian and Devanandan, 1983;Halata et al, 1986;Schenk et al, 1996). SAII afferents have also been reported in electrophysiological studies of the hairy skin innervation in monkeys (Iggo, 1963;Harrington and Merzenich, 1970).…”

Classically recognized as the cutaneous stretch receptors associated with the slowly adapting type II (SAII) primary afferents, Ruffini corpuscles have rarely been reported in the skin, despite numerous histologic investigations. Electrophysiological recordings of the primary afferents in humans suggest that SAII fibers represent approximately 15% of the myelinated mechanosensitive axons in the peripheral nerves innervating the volar surface of the hand. In the present study, an analysis of glabrous skin was conducted in human donors to assess the distribution of Ruffini and Ruffini-like corpuscles in the distal phalanx of the index finger. Only one presumptive Ruffini corpuscle was found in the skin processed for double immunofluorescence labeling with antibodies against protein gene product 9.5 and neurofilament 200-kDa subunit. Based on their relatively scattered distributions, we conclude that very few SAII primary afferents are likely to terminate as Ruffini corpuscles in human glabrous skin.

“…Both Pacinian corpuscles and Meissner corpuscles are known to be abundant in the glabrous skin area both in man and other primates. Pacinian corpuscles are found both in superficial and deeper layers of the subcutaneous adipose tissues, as well as in association with deeper structures such as the palmar aponeurosis and the digital tendon sheaths (Stilwell, 1957;Quilliam & Ridley, 1971). Meissner corpuscles are abundant in the dermal papillae of human glabrous skin (e.g.…”

1. Single unit impulses were recorded from the ulnar and median nerves of awake human subjects with tungsten electrodes inserted percutaneously in the upper arm. 2. Forty‐nine rapidly adapting mechanoreceptors with receptive fields in the glabrous skin area were studied. Thirty‐nine units had small receptive fields with distinct borders (RA‐receptors) while ten units had large fields with indistinct borders (PC‐receptors). 3. The afferent response to stimuli of varying indentation amplitude and velocity of indentation, was analysed. 4. Amplitude thresholds varied from 0·05 to 1·65 mm for the RA‐receptors. For the PC‐receptors amplitude thresholds ranged from less than 0·05 to 1·95 mm. 5. Velocity thresholds varied for the RA‐receptors from 0·4 to 39·3 mm/sec, and for the PC‐receptors from 0·5 to 19·6 mm/sec. 6. The conduction velocities of the afferents were all in the A α—β range. For the RA‐receptors the conduction velocities ranged from 26 to 91 m/sec (mean = 55·3 ± 3·4), and for PC‐receptors the range was from 34 to 61 m/sec (mean = 46·9 ± 3·6). 7. The nerve impulse frequency as a function of indentation velocity was analysed for nineteen RA‐receptors and four PC‐receptors. A hyperbolic log tangent function of the type first introduced by Naka & Rushton (1966) in studies on S‐potentials in the fish retina was found to be the best description of the stimulus—response function for sixteen RA‐receptors and two PC‐receptors. For the remaining units a pure logarithmic function was the best description. However, the logarithmic function may be, as found in the present study, a special case of the more general log tanh function.
