Why does selective blocking of inhibitory synapses lead to muscle spasms?
Selective blocking of inhibitory synapses can lead to muscle spasms because inhibitory synapses normally help balance the activity of excitatory synapses. When inhibitory synapses are blocked, there is an imbalance in neuronal activity, leading to increased excitation of motor neurons and muscles. This imbalance can result in uncontrolled and excessive muscle contractions, which manifest as muscle spasms.
Where are electrical synapses found?
Synapse is located, where two neurons meet each other. One cubic cm of brain cortex have about one billion synapses, probably.
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 factors affect muscle contraction?
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
Can a single motor neuron for synapses with just one muscle cell?
A single motor neuron will innervate many muscle cells

The venom of the black widow spider causes violent muscle contractions by flooding synapses with?
It floods the synapses with Acetycholine or ACh.
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
How do muscle stretch receptors contribute to the body's ability to sense and respond to changes in muscle length during physical activity?
Muscle stretch receptors are sensory receptors located in muscles that detect changes in muscle length. When a muscle is stretched during physical activity, these receptors send signals to the brain, which helps the body sense and respond to the changes in muscle length. This information is important for maintaining balance, coordination, and muscle control during movement.
What muscle do you stretch when you do the flamingo stretch?
Quadrilateral
Which reflexes are particularly important in maintaining balance?
The vestibulo-ocular reflex (VOR), vestibulospinal reflex, and the stretch reflex in muscles are important for maintaining balance. The VOR helps stabilize vision during head movements, the vestibulospinal reflex controls muscle tone and posture in response to vestibular signals, and the stretch reflex helps adjust body position based on muscle length changes.
What sends messages to your brain and spinal cord and muscle cells?
Synapses let the "message" travel to muscle cells.
Why do you stretch a lot?
Stretching helps to improve muscle strength. Tight muscles during exercise can actually cause problems. It is best to stretch before and after a workout.
Where are electrical synapses found?
Synapse is located, where two neurons meet each other. One cubic cm of brain cortex have about one billion synapses, probably.
What muscle do you stretch when you do the butterfly stretch?
Your groin is being stretched.
Stretch muscle vs non stretch muscles?
buttocks
Why does the muscle cell have a long shape?
The cell is long because the , muscle needs to stretch and contract when you use that muscle. Therefore it needs to be long in order to stretch.
