noci-|nəʊsɪ|
comb. form of L. noc-ēre to do harm, used in a few terms, esp. in neurology, as nociˈceptive a. Physiol. [receptive a.], (of a stimulus) painful; responding to or caused by such a stimulus; hence nociˈceptor [receptor], any sensory receptor for painful stimuli; nociˈfensor a. [L. dē-fens-, ppl. stem (in defensive a., etc.): cf. L. dēfensor defender] (of a nerve) concerned in the transmission of the sensation of pain.
1904C. S. Sherrington in Nature 8 Sept. 463/1 In this reaction the reflex arc is (i) the receptive neurone..(nociceptive) from the foot to the spinal segment, (ii) perhaps a short intraspinal neurone, and (iii) the motor neurone..to the flexor muscle. Ibid., Stimulation (nociceptive) of the foot causes flexion of its own leg and extension of the opposite. 1956Nature 18 Feb. 340/1 In the lightly anæsthetised preparations, nociceptive stimuli, twisting the pinna and electrical stimulation of the reticular activating system produced transient changes in the cortical blood-flow. 1961Lancet 2 Sept. 546/2 Dr. W. Koll..described his work on the action of various pharmacological substances on nociceptive spinal reflexes. 1974Sci. Amer. Jan. 43/1 The nociceptive (N) cells require still stronger mechanical stimuli.
1906C. S. Sherrington Integrative Action Nervous Syst. ix. 330 The reaction initiated by a noci-ceptor..is to be regarded as consummatory. 1967Jrnl. Physiol. CXC. 541 Seventy-four fibres conducting between 6 and 37 m/sec were classified as nociceptors because they responded only to damaging mechanical stimulation of the skin.
1936T. Lewis in Clin. Sci. II. 402 It will be evident that any system of nerve fibres, which in the exercise of its function gives rise to no obvious and distinctive external manifestations, will tend to escape recognition... The need to postulate a new system of nerves has arisen to explain hitherto unrecognised phenomena. The nerves of this system are at present unnamed. Because they are associated with local defence against injury I propose to call them the ‘nocifensor nerves’. 1964J. Z. Young Model of Brain xiii. 209 They are presumed to be nocifensor (pain) fibres, coming either direct from the periphery or after synapse in the sub-vertical lobe. |
