Axons of motor neurons also terminate in muscle spindles they make synapses at either or both of the ends of the intrafusal muscle fibers and regulate spindle sensitivity.
nuclear chain fibers and the axons of sensory neurons.static nuclear bag fibers (bag 2 fibres).dynamic nuclear bag fibres (bag 1 fibres).They are composed of 3-10 intrafusal muscle fibres, of which there are three types: “Gray938” By Henry Vandyke Carter – Henry Gray (1918) Anatomy of the Human Body (See “Book” section below)Bartleby.Muscle spindles are found within the fleshy portions of muscles, embedded in so-called extrafusal muscle fibres. “Muscle spindle model” By Neuromechanics – Own work (Public Domain) via Commons WikimediaĢ.

Moreover, muscle spindle is involved in reciprocal inhibition while Golgi tendon organ is involved in autogenic inhibition. Thus, this is the key difference between muscle spindle and Golgi tendon organ. On the other hand, Golgi tendon organ is sensitive to the changes in muscle tension. Muscle spindle is sensitive to the rate at which a muscle stretches and the extent to which the muscle is stretched. Muscle spindle and Golgi tendon organ are two sensory organs present in the muscle-tendon unit. Summary – Muscle Spindle vs Golgi Tendon Organ Moreover, stretch reflex and reciprocal inhibition are the protective functions of muscle spindles, while autogenic inhibition is the protective function that is done by the Golgi tendon organ. Besides, muscle spindle consists of intrafusal muscle fibers enclosed in a sheath (spindle), while Golgi tendon organ consists of braided strands of collagen which are encapsulated. So, this is the key difference between muscle spindle and Golgi tendon organ. The muscle spindle is a small spindle-shaped sensory organ that senses the changes in the length of the muscle and the rate of lengthening, while Golgi tendon organ is a sensory organ in the muscle-tendon unit that senses the changes in the muscle tension. What is the Difference Between Muscle Spindle and Golgi Tendon Organ? They help to protect muscle form damages or injuries.Muscle spindle and Golgi tendon organ work together in a muscle.What are the Similarities Between Muscle Spindle and Golgi Tendon Organ? A muscle spindle contains several differentiated muscle fibers that are enclosed in a spindle-shaped connective tissue sac. In the muscle, muscle spindles run parallel with the main muscle fibers. The muscle spindle is a small, spindle-shaped sensory organ located in the skeletal muscle tissue. Side by Side Comparison – Muscle Spindle vs Golgi Tendon Organ in Tabular Form Similarities Between Muscle Spindle and Golgi Tendon Organĥ. Muscle spindle is involved in reciprocal inhibition while GTO is involved in autogenic inhibition. Autogenic and reciprocal inhibition are two types of reflex relaxations that protect muscles from damages and injuries. In contrast, GTO senses excessive tension of the muscle and inhibits muscle activation in order to decreases the tension of muscle and tendons. Muscle spindle senses the change in the length of the muscle as well as the speed of lengthening of the muscle. Muscle spindle and Golgi tendon organ (GTO) are two types of sensory organs present in the muscle– tendon unit. The key difference between muscle spindle and Golgi tendon organ is that muscle spindle is a sensory organ that senses the changes in muscle length and the rate of lengthening, while Golgi tendon organ is a sensory organ that senses the changes in muscle tension.
