What else can I help you with?
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
Does The muscle spindle detect excessive stretch within the muscle?
True.
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.
When does the activation of a motor neuron occur in a stretch flex?
The activation of a motor neuron in a stretch reflex occurs when a muscle spindle detects a quick stretch in a muscle. This sensory information is relayed to the spinal cord, where it synapses with the motor neuron corresponding to the stretched muscle. The motor neuron is then activated, causing the muscle to contract and counteract the stretch, leading to the reflexive response. This process happens rapidly, often without conscious thought, to protect the muscle from excessive stretching.
What type of receptor detects muscle length?
Muscle Spindle
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 the Name of the receptor for the stretch reflex?
The receptor for the stretch reflex is called the muscle spindle. Muscle spindles are sensory receptors located within the belly of muscles, and they detect changes in muscle length and the rate of that change. When a muscle is stretched, the muscle spindle initiates the stretch reflex, leading to a contraction of the muscle to resist the stretch. This reflex helps maintain posture and balance.
What is trauma to a muscle or the muscle-tendinous units from violent contraction or excessive forcible stretch?
a muscle strain
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.
