Sensors in the tendon, the Golgi tendon organ, are activated upon stretch of the tendon, which requires considerable force.
These sensors synapse on interneurons in the spinal cord that inhibit further activity of the motor neurons innervating the muscle.
This relaxation of the muscle prevents damage from excess force.
How does the Golgi tendon organ prevent injury?
The golgi tendon organ is a proprioceptor, sense organ that receives information from the tendon, that senses TENSION. If there is too much muscle tension the golgi tendon organ will inhibit the muscle from creating any force (via a reflex arc), thus protecting the you from injuring itself.
What does the Golgi tendon organ do?
The Golgi tendon organ (GTO) (also called Golgi organ, tendon organ, neurotendinous organ or neurotendinous spindle) is a proprioceptive sensory receptor organ that senses changes in muscle tension. It lies at the origins and insertion of skeletal muscle fibers into the tendons of skeletal muscle.
What does the Golgi tendon reflex do?
The Golgi tendon reflex operates as a protective feedback mechanism to control the tension of an active muscle by causing relaxation before the tendon tension becomes high enough to cause damage.
What is the function of muscle spindles and Golgi tendon organs?
Two of these components—Golgi tendon organ (GTO) and muscle spindle—belong to the nervous system and function to influence movement. Two important proprioceptors that play a role in flexibility, the GTO and muscle spindle work together reflexively to regulate muscle stiffness.
Where is the Golgi tendon located?
Stretch receptors called Golgi tendon organs are found within the collagen fibers of tendons and within joint capsules. They are generally located in series with the muscle rather than the parallel arrangement of the intrafusal muscle fibers.
What is the difference between Golgi tendon and muscle spindle?
Golgi Tendon Organ Vs Muscle spindle
Golgi tendon organs are activated when the tendon attached to an active muscle is stretched. The result is a reduction in tension within the muscle and tendon.Thus, whereas spindles facilitate activation of the muscle, neural input from GTOs inhibits muscle activation.
What happens when muscle spindle is stretched?
Their job is to detect changes in muscle length and the speed of change in muscle length. Below is an image of a muscle spindle. When muscles lengthen, the spindles are stretched. This stretch activates the muscle spindle which in turn sends an impulse to the spinal cord.
How are muscle spindles activated?
Muscle spindles are proprioceptors that consist of intrafusal muscle fibers enclosed in a sheath (spindle). This stretch causes the sensory neuron in the spindle to transmit an impulse to the spinal cord, where it synapses with alpha motor neurons. This causes activation of motor neurons that innervate the muscle.
Are tendons considered organs?
It is present in almost every organ, forming a large part of skin, tendons, joints, ligaments, blood vessels, and muscles.
What is the difference between stretch and tendon reflex?
Stretch of a muscle normally happens when its antagonist contracts, or artificially when its tendon is stretched, as in the knee jerk reflex. Tendon receptors respond to the contraction of a muscle. Their function, like that of stretch reflexes, is the coordination of muscles and body movements.
What is a tendon reflex?
Tendon reflex (or T-reflex) may refer to: A stretch reflex, when the stretch is created by a blow upon a muscle tendon. Tendon reflex tests are used to determine the integrity of the spinal cord and peripheral nervous system, and they can be used to determine the presence of a neuromuscular disease.
What is stretch reflex?
The stretch reflex (myotatic reflex) is a muscle contraction in response to stretching within the muscle. It is a monosynaptic reflex which provides automatic regulation of skeletal muscle length. When a muscle lengthens, the muscle spindle is stretched and its nerve activity increases.
What are muscle spindles sensitive to?
The spindle is a stretch receptor with its own motor supply consisting of several intrafusal muscle fibres. Muscle spindles are stretch receptors within the body of a muscle that primarily detect changes in the length of the muscle. They convey length information to the central nervous system via afferent nerve fibers.
Are muscles organs?
The muscular system is responsible for the movement of the human body. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves. Muscle tissue is also found inside of the heart, digestive organs, and blood vessels.
What causes muscle tension?
Muscle tension is caused when a muscle contracts and does not release, which is not a healthy condition. Muscle tension can be caused by a physical occurrence such as overuse, or it can be a product of stress. According to WebMD, muscle tension caused by stress, if left untreated, can lead to tension headaches.
