Efferent Pathways definition: Nerve structures through which impulses are conducted from a nerve center toward a peripheral site. Such impulses are conducted via efferent neurons (NEURONS, EFFERENT), such as MOTOR NEURONS, autonomic neurons, and hypophyseal neurons.
Efferent Pathway definition: Nerve structures through which impulses are conducted from a nerve center toward a peripheral site. (MeSH)
Motor Neurons, Gamma definition: Motor neurons which activate the contractile regions of intrafusal SKELETAL MUSCLE FIBERS, thus adjusting the sensitivity of the MUSCLE SPINDLES to stretch. Gamma motor neurons may be "static" or "dynamic" according to which aspect of responsiveness (or which fiber types) they regulate. The alpha and gamma motor neurons are often activated together (alpha gamma coactivation) which allows the spindles to contribute to the control of movement trajectories despite changes in muscle length.
Gamma Motor Neuron definition: Motor neurons which activate the contractile regions of intrafusal muscle fibers, thus adjusting the sensitivity of the muscle spindles to stretch. (MeSH)
Neurons, Efferent definition: Neurons which send impulses peripherally to activate muscles or secretory cells.
efferent nerve definition: neurons which send impulses peripherally to activate muscles or secretory cells.
Efferent Neuron definition: Neurons which send impulses peripherally to activate muscles or secretory cells. (MeSH)
Efferent Duct definition: One of 12 to 14 small seminal ducts leading from the testis to the head of the epididymis.
olivocochlear bundle definition: bundle of nerve fibers which arise from cells in or adjoining the superior olive and pass dorsomedially as the peduncle of the superior olive; most fibers cross the median plane and leave the brain stem with the vestibular nerve, then join the cochlear nerve and enter the cochlea; they cross the inner tunnel of the spiral organ as tunnel fibers and end primarily on the outer hair cells, presumably to modulate the function of the inner hair cells; these connections are thought to inhibit unwanted auditory impulses and sharpen frequency resolving power.
Visceral Efferent Neuron definition: A cell that conducts a nerve impulse that originated in the central nervous system and proceeds towards one of the interior organs of the one of the three cavities of the body.
