What is synapse and reflex action?
A synapse is a junction between two neurons where neurotransmitters are released to facilitate communication, allowing signals to be transmitted across the nervous system. Reflex action is an automatic and rapid response to a stimulus, often mediated through a reflex arc that bypasses the brain for quicker reactions. For example, touching a hot surface triggers a reflex that causes immediate withdrawal of the hand, demonstrating the efficiency of synaptic transmission in this process.
Differences btn simple reflex and conditioned reflex action?
A simple reflex action is an automatic, involuntary response to a stimulus that involves a direct pathway through the spinal cord, such as the knee-jerk reflex. In contrast, a conditioned reflex action is a learned response that occurs when a neutral stimulus becomes associated with an unconditioned stimulus, as seen in Pavlov's experiments with dogs. While simple reflexes are innate and require no prior learning, conditioned reflexes depend on experience and can be modified over time.
Why does reflex reinforcement work?
Instead of being processed in the brain, a reflex arc is processed in the vertebra, this allows for faster reflexes. Example of when the reflex arc is used is when a person touches a hot stove. The immediate response (which the reflex arc causes) is to pull away, but it doesn't really hurt till a few seconds after. This is because the brain was first bypassed, but has now had time to process what happened.
Which reflex shows the least synaptic delay?
The monosynaptic reflex, such as the knee-jerk reflex, has the least synaptic delay because it involves only one synapse between sensory and motor neurons in the spinal cord. This direct connection allows for a rapid response to a stimulus.
What type of reflex operates independently of the cns?
The simplest type of reflex that operates independently of the central nervous system is a monosynaptic reflex involving a single synapse between sensory and motor neurons in the spinal cord. This reflex arc allows for a rapid response to a stimulus without requiring input from the brain.

A reflex pathway having only one synapse in the CNS?
Reflexes are rapid involuntary responses to a given stimuli. The reflex pathway that only has one synapse in the CNS is called the monosynaptic reflex arc.
What is a simple reflex action?
someone tapping your knee and you kick
In a three neuron reflex arc the afferent neurons synapse with?
In a three neuron reflex arc, the afferent neurons synapse with interneurons in the spinal cord or brainstem. The interneurons then synapse with efferent neurons which transmit the signal to the effector organ to initiate a response.
Which is the name for a quick unlearned and automatic response A impulse B synapse C reflex?
C reflex

Is sweating a reflex action?
No it is not a reflex action
Why is response time in a monosynaptic reflex much faster than response time in a polysynaptic reflex?
Transmission across a chemical synapse always involves a synaptic delay, but with only one synapse (a monosynaptic reflex), the delay between stimulus and response is minimized. In a polysynaptic reflex, the length of delay is proportional to the number of synapses involved.
What happends at the synapse during the reflex?
During a reflex, the synapse serves as the critical junction where neurotransmitters are released from the presynaptic neuron, allowing communication with the postsynaptic neuron. When a sensory neuron detects a stimulus, it transmits an electrical signal to the spinal cord, where it synapses with an interneuron or motor neuron. This rapid transmission enables a quick response, often bypassing the brain for immediate action. Ultimately, the motor neuron then sends a signal to the muscles, initiating a reflexive action.
A rapid simple automatic response that involves few neurons is?
A reflex action is a fast, automatic response to a stimulus by an effector organ i.e. a muscle.
What is the relationship between the action potential and the synapse?
A synapse and an action potential have a flip-flopping cause and effect relationship, in that an action potential in a presynaptic neuron initiates a release of neurotransmitters across a synapse, which can then subsequently potentially trigger an action potential in the axon of the postsynaptic neuron, which would then cause release of neurotransmitters across a following synapse.
