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.
What neuron connects an afferent neuron to an efferent neuron?
The interneuron acts as a connector between afferent and efferent neurons in the central nervous system. It integrates and processes incoming sensory information before transmitting signals to the efferent neuron to produce a response.
An impulse reaches the CNS from the PNS via the?
An impulse reaches the central nervous system (CNS) from the peripheral nervous system (PNS) through neurons. Sensory neurons in the PNS transmit signals to interneurons in the CNS, which then relay the information to motor neurons to generate a response.
What occur during reflex arc?
Definitions: 1. afferent neuron - sensory nerve 2. efferent neuron - motor nerve 3. monosynaptic - see below There are different types of reflexes but the simplest type is a monosynaptic reflex. This means the afferent neurons connect directly to the efferent neurons. For example the knee jerk reflex is a monosynaptic reflex: 1. The patellar tendon is stretched. 2. The afferent neuron (which has stretch sensors) send a signal up to the spinal cord. 3. In the spinal cord at the synapse. The electrical signal is changed to a chemical signal. 4. Chemical messengers travel across the synapse and stimulate the efferent neuron. 5. The efferent neuron changes these signals into electrical signals which travel down to the quadriceps muscle. 6. There is another synapse connecting the nerve to the muscle. chemical messengers travel across the synapse and stimulate the muscle to contract.
What is any drug that inhibits transmission of sensory impulses at a synapse?
A drug that inhibits transmission of sensory impulses at a synapse is a nerve block agent. These drugs work by blocking the transmission of nerve signals through the synapse, effectively reducing or eliminating sensation in a specific area of the body. Nerve block agents are commonly used for regional anesthesia and pain management procedures.
What is an important synapse site for afferent fibers traveling to the sensory cortex?
The thalamus.
Synapse site for afferent fibers to sensory cortex?
Thalamus
What is the site of axons and afferent neurons?
The site of axons and afferent neurons is the peripheral nervous system. Afferent neurons carry sensory information from the periphery to the central nervous system, while axons are the long projections of neurons that transmit electrical impulses away from the cell body to other neurons or muscles.
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.
What is the name of the synapse site in the brain for afferent fibers that travel to the sensory cortex?
i think it is the choroid plexus....not for sure though ---- Afferent sensory fibers (those returning to the brain from the periphery) synapse first in the posterior horn of the spinal cord, ascend one to two levels and decussate (cross over) at the anterior white commissure before their axons migrate to the anterior or lateral spinothalamic tracts. These then synapse again in the thalamus for integration before they go on to the post-central gyrus - the sensory cortex - and other sites in the cortex.
What is the majority of all afferent pathways pass through and synapse with neurons?
The motor neuron is the final common pathway for all neurons to travel to complete their synapse. Afferent neurons or unipolar neurons all pass through the cord and brain on this journey.
What interprets messages transmitted by sensory neurons?
it was the synapse
What neuron connects an afferent neuron to an efferent neuron?

Information acquired by chemical stimull or response to the environment that is directed to the brain?
sensory or synapse
All processing at the circuit level going up to the perceptual level must synapse in the?
thalamus, which acts as a relay station for sensory information traveling to the cerebral cortex. It plays a crucial role in processing sensory inputs before they reach higher brain regions responsible for perception.
What is any drug that inhibits trans mission of sensory impulse at a synapse called?
Pain medication
