What else can I help you with?
The muscle spindle detects excessive stretch within the muscle?
True
What detects a muscle is under stretch and therefore initiates the inverse stretch flex?
the muscle spindle detects excessive stretch within the muscle , it response and makes the muscle contract
What are the main roles of the Golgi Tendon Organ and the Muscle Spindle?
The Golgi tendon organ senses changes in muscle tension and helps protect muscles from excessive force by inhibiting muscle contraction. The muscle spindle detects changes in muscle length and contributes to muscle stretch reflexes and coordination of movement.
Sensory receptors found in muscle and tendons that detect their degree of stretch?
the muscle spindle detects it, and causes reflexes that automatically make slight alterations to muscle tentions, so that you stand up right.
What is trauma to a muscle or the muscle-tendinous units from violent contraction or excessive forcible stretch?
a muscle strain
What maintains the tension in a muscle spindle?
The tension in a muscle spindle is maintained by intrafusal muscle fibers, which are specialized muscle fibers within the spindle that are innervated by sensory nerve fibers. These sensory fibers detect changes in muscle length and transmit signals to the central nervous system to regulate muscle tone and coordination.
Which fibers in the skeletal muscle are stimulated only by the degree of stretch?
Muscle spindles are the fibers in skeletal muscles that are stimulated by the degree of stretch. These specialized sensory organs detect changes in muscle length and contribute to the stretch reflex, helping to maintain posture and control muscle contraction.
What is the primary role of muscle spindles?
the striated portions of the intrafusal fiber contract to keep the spindle taut at different muscle lengths. If the whole muscle is stretched, the muscle spindle is also stretched, triggering sensory nerve impulses on its nerve fiber. These sensory fibers synapse in the spinal chord with lower motor neurons leading back to the same muscle. Impulses triggered by stretch of the muscle spindle contract the skeletal muscle.
Is muscle sensations when rowing a boat a muscle spindle?
Muscle Spindle and Golgi Tendon Organ
What would happen if you overstretched your muscle?
Overstretching of a muscle initiates a stretch reflex spasm where the muscle spindle cells relay a message to the spinal cord, and an efferent message is sent to motor units to contract the muscle, thereby causing a muscle spasm.
What activity is musicle spindle?
A muscle spindle tightens when the muscle is stretched too far too fast to prevent damage to the muscle.
How to increase the muscle spindle reflection?
You can increase the muscle spindle reflection by exercising and taking lots of proteins.
