When does the activation of a motor neuron occur in a stretch reflex?
The activation of a motor neuron in a stretch reflex occurs when muscle spindles detect a stretching of the muscle, leading to the generation of action potentials. These signals are transmitted to the spinal cord, where they synapse directly with alpha motor neurons. This direct connection allows for a rapid response, causing the muscle to contract and counteract the stretch almost immediately. This reflex arc is crucial for maintaining posture and balance.
Neurons that serve as links between the sensory neuron and the motor neurons?
interneurons also known as: ASSOCIATION NEURONS
How does activation energy affect the progress affect the progress of a reaction?
The reaction will not occur unless the activation energy is met.
How does muscle weakness affect patient motor neuron diseases with?
Muscles of the legs are most often affected, leading to clumsiness, unstable gait, or lower limb paralysis. Muscle cramps and fasciculations (twitching) occur with most motor neuron diseases. Facial muscles may also be affected
Does activation energy depend on collision frequency?
No, activation energy is a fixed value for a specific reaction and does not depend on collision frequency. Activation energy is the minimum amount of energy required for a reaction to occur, while collision frequency relates to the number of collisions that occur in a given time period.

Where does synapses occur in the spinal cord?
Cell body of sensory neuron - in dorsal root ganglion. Cell body of motor neuron - in anterior gray horn.
How does reflex occur?
This is what happens:a receptor detects a stimulus (change in the environment)a sensory neuron sends a signal to the relay neuronthe relay neuron sends the signal to the motor neuronthe motor neuron sends a signal to the affected partthe affected part produces a response
How do sensory neurons function?
sensory neuron har two part one is connect receptor which take al body sensory information and than neuron aftr that tract and finaly brain in relatd centr aftr that motor reaction occur this reaction occur in apathway.
How many synapses occur in this reflex arc?
In a simple reflex arc, there are typically three neurons and two synapses. The sensory neuron carries the signal from the receptor to the central nervous system, where it synapses with the interneuron. The interneuron then synapses with the motor neuron, which carries the signal to the effector organ to produce a response.

Do you have any special medicine for motor neuron disease?
Motor neurone diseases occur when parts of the nervous system become damaged beyond repair. Unfortunately, there is not a cure for motor neurone disease, however there are medicines that doctors can give to help with symptoms.
What is activation enery?
Activation energy is the amount of energy that a chemical reaction requires to occur.

Muscles of the legs are most often affected, leading to clumsiness, unstable gait, or lower limb paralysis. Muscle cramps and fasciculations (twitching) occur with most motor neuron diseases. Facial muscles may also be affected
Why does hyperpolarization cause a spike to occur?
Hyperpolarization causes a spike to occur because it increases the difference in electrical charge between the inside and outside of a neuron, making it more likely for the neuron to generate an action potential or spike.
Does activation energy depend on collision frequency?
No, activation energy is a fixed value for a specific reaction and does not depend on collision frequency. Activation energy is the minimum amount of energy required for a reaction to occur, while collision frequency relates to the number of collisions that occur in a given time period.
