Nuclear bag fibers
Did you know?
A nuclear bag fiber is a type of intrafusal muscle fiber that lies in the center of a muscle spindle. Each has many nuclei concentrated in bags and they cause excitation of the primary sensory fibers. There are two kinds of bag fibers based upon contraction speed and motor innervation. BAG2 fibers are … Meer weergeven • Nuclear chain fiber Meer weergeven • Meer weergeven WebNuclear bag fibers were of two types, bag1 and bag2, histochemically, and they displayed two distinct types of ultrastructure. Nuclear chain fibers were histochemically and ultrastructurally homogeneous. Regional differences in enzymatic staining and ultrastructure occurred along individual intrafusal fibers.
WebThese fibers are oriented parallel to the regular, power-producing extrafusal muscle fibers. Multiply innervated and named according to the arrangement of their nuclei as nuclear … WebThere are two types of intrafusal muscle fibers: nuclear bag fibers and nuclear chain fibers. [3] They bear two types of sensory ending, known as annulospiral and flower-spray endings. Both ends of these fibers contract, but the central region only stretches and does not …

Web12 sep. 2024 · Ia, II, and GMNs innervate these fibers. [5] Dynamic Nuclear Bag Fibers: Though structurally similar to static nuclear bag fibers, these serve a different functional purpose of relaying information on the velocity (rate of change in length) of muscle stretch. Ia and GMNs only innervate these fibers. [5]
