fusimotoradj.

/ˈfjuːzɪməʊtə/

Etymology: < Latin fūsus spindle + motor n. 4.

Physiology.

Of, pertaining to, or designating the motor neurones with fibres of small diameter which innervate the intrafusal fibres (spindles) of muscle.

1958 Hunt & Paintal in Jrnl. Physiol. 143 195 The motor fibres to the spindle have been designated γ efferents by Leksell (1945) and small motor fibres by Kuffler et al. (1951). Both designations have possible ambiguity... We therefore propose the term fusimotor with reference to neurones that are motor to the muscle spindle.

1962 P. B. C. Matthews in Q. Jrnl. Exper. Physiol. XLVII. 327 There exist fusimotor fibres of two functionally distinct kinds, which for the purposes of the present description, and for the want of better terms, will be called static and dynamic fusimotor fibres.

1968 Jrnl. Physiol. 195 420 It has been proposed that voluntary movement may be initiated and sustained by the activation of fusimotor neurones..operating the muscle spindles and monosynaptic reflex as a follow-up length servo.

1969 Proc. Royal Soc. B. 173 162 It is difficult to see how such a segmental motor apparatus could allow the cortex to initiate precise movements of the hand, employing only the fusimotor route.
