Why does selective blocking of inhibitory synapses lead to muscle spasms?
BraddersIRE
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?
Electrical synapses are found in the central nervous system, such as in the brain and spinal cord. They are also found in smooth muscle tissues and cardiac muscle tissues.
How many synapses are crossed in a single reflex arc during a muscle stretch reflex?
A single reflex arc during a muscle stretch reflex involves two synapses: one at the sensory neuron in the spinal cord where the signal is transmitted to the motor neuron, and another at the neuromuscular junction where the motor neuron stimulates the muscle to contract.
Can a single motor neuron for synapses with just one muscle cell?
A single motor neuron will innervate many muscle cells
What are neuromuscular blocking agents?
Neuromuscular blocking agents are medications that work by blocking the transmission of nerve signals to the muscles, resulting in muscle paralysis. They are used during surgical procedures to facilitate intubation, reduce muscle movements, and provide muscle relaxation. These medications are administered by anesthesiologists and require monitoring to prevent complications.
What are the reaction that having a great time leaping across synapses?
There are no reactions, the end of a nerve produces a gas that goes across the synapses and creates the electrical impulse on the other side of the synapses and continues the message!
The venom of the black widow spider causes violent muscle contractions by flooding synapses with?
It floods the synapses with Acetycholine or ACh.
What sends messages to your brain and spinal cord and muscle cells?
Synapses let the "message" travel to muscle cells.
Where are electrical synapses found?
Electrical synapses are found in the central nervous system, such as in the brain and spinal cord. They are also found in smooth muscle tissues and cardiac muscle tissues.
When acetylcholine is blocked from neuron endings what happens?
Blocking acetylcholine from neuron endings can prevent the transmission of nerve impulses across synapses. This can lead to muscle weakness, impaired movement, and other symptoms associated with conditions like myasthenia gravis or drug-induced paralysis.
How many synapses are crossed in a single reflex arc during a muscle stretch reflex?
A single reflex arc during a muscle stretch reflex involves two synapses: one at the sensory neuron in the spinal cord where the signal is transmitted to the motor neuron, and another at the neuromuscular junction where the motor neuron stimulates the muscle to contract.
The Golgi tendon organ GTO muscle spindle and Pacinian corpuscles make up the three primary?
Inhibitory proprioceptors
Can a single motor neuron for synapses with just one muscle cell?
A single motor neuron will innervate many muscle cells
Are beta blockers blood thinners?
No, they are drugs that counteract the effect of catecholamines between synapses and suppress inotropic effect of the heart muscle
Just what does pass from neuron to the muscle cells?
via chemicals called neurotransmitters, expressed at sites called synapses, which are tiny gaps between a neuron and another neuron or a muscle cell.
Is damage to the heart muscle caused by a thrombus blocking a coronary artery?
Coronary Thrombosis
Is the damage to the heart muscle caused by a thrombus blocking a coronary artery?
Coronary Thrombosis
What is the stimulus for the knee jerk reflex?
Striking the patellar tendon with a tendon hammer just below the patella stretches the muscle spindle in the quadriceps femoris muscle. This produces a signal which travels back to the spinal cord and synapses (without interneurons) at the level of L4 in the spinal cord, completely independent of higher centres. From there, an alpha-motor neuron conducts an efferent impulse back to the quadriceps femoris muscle, triggering contraction. This contraction, coordinated with the relaxation of the antagonistic flexor hamstring muscle causes the leg to kick. This reflex is a reflex of proprioception which helps maintain posture and balance, allowing to keep one's balance with little effort or conscious thought.The patellar reflex is a clinical and classic example of the monosynaptic reflex arc. There is no interneuron in the pathway leading to contraction of the quadriceps muscle. Instead the bipolar sensory neuron synapses directly on a motor neuron in the spinal cord. However, there is an inhibitory interneuron used to relax the antagonistic hamstring muscle.
