Many neurons of the ENS re components of GI reflex pathways that regulate GI secretion and mobility in response to stimuli present in the lumen of the GI tract
1. sensory receptors (such chemoreceptors nd stretch receptors)
2. the axons of the sensory neurons can synapse with other neurons located in the ENS, CNS, OR ANS
3. the neuons of the ENS, CNS, or ANS subsequently activate or inhibit GI glads and smooth muscles, altering GI secretion and motility
What else can I help you with?
The simplest pathway of an impulse is?
The simplest pathway of an impulse involves the sensory neuron transmitting a signal to the interneuron in the spinal cord, which then relays the signal to the motor neuron, causing a response in a muscle or gland. This pathway is known as a reflex arc and allows for rapid, automatic responses to stimuli without involving the brain.
The sensory receptor sensory neuron motor neuron and effector involved in a reflex form a?
The sensory receptor, sensory neuron, motor neuron, and effector involved in a reflex form a reflex arc. This is a neural pathway that controls a reflex action in response to a stimulus without conscious thought.
Define reflex arc and list its elements?
A Reflex Arc is a neural pathway for reflexes that is involved in CNS and PNS. The five elements are: 1. Sensory receptor (Reacts to stimuli) 2. Sensory or Afferent neuron (takes information to the CNS) 3. Integration Center (Spinal Cord or Brain processes information) 4. Motor or Efferent neuron (carries signal away from CNS) 5. Effector organ (muscles or glands)
How might damage to the spine affect a reflex arc?
Damage to the spine can interrupt the transmission of nerve impulses involved in the reflex arc, leading to impaired or absent reflex responses. Depending on the location and severity of the damage, reflexes may be diminished, exaggerated, or completely absent. Physical therapy and rehabilitation techniques may help restore some function in reflex arcs affected by spinal damage.
What two cranial nerves on the stimulated side must be functional for pupillary light reflex to occur?
The two cranial nerves that must be functional for the pupillary light reflex to occur are cranial nerve II (optic nerve) for the afferent pathway (carrying the visual information from the retina to the brain) and cranial nerve III (oculomotor nerve) for the efferent pathway (carrying the motor response to constrict the pupil).
What is the pathway of reflex?
reflex arc
What is the pathway between the receptor and the control center in the reflex pathway?
Afferent pathway
The neural pathway of a single reflex is called?
Reflex Arc
What is the pathway between the receptor and the control center in the reflex pathway called?
Afferent pathway
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 the neural pathway of a single reflex called?
The neural pathway of a single reflex is called a reflex arc. It involves the sensory neuron carrying information from the receptor to the spinal cord, where it synapses with a motor neuron that carries the response signal to the effector muscle or organ. This simple pathway allows for rapid, involuntary responses to stimuli.
What nerve acts as the afferent pathway in the pupillary reflex?
The optic nerve (cranial nerve II) carries sensory information about light intensity to the brain as part of the afferent pathway in the pupillary reflex.
How can you remember the stages of a reflex arc in chemistry?
To remember the stages of a reflex arc in chemistry, you can use the acronym "SAID" which stands for stimulus, afferent pathway, integration center, and efferent pathway, and then the response. This mnemonic can help you recall the order of events in a reflex arc.
What is the name of the short pathway that carries the impulse for an automatic response?
The short pathway that carries the impulse for an automatic response is called a reflex arc. It involves sensory neurons, interneurons in the spinal cord, and motor neurons to quickly produce a reflex action in response to a stimulus, bypassing the brain.
The simplest pathway of an impulse is?
The simplest pathway of an impulse involves the sensory neuron transmitting a signal to the interneuron in the spinal cord, which then relays the signal to the motor neuron, causing a response in a muscle or gland.

The sensory receptor, sensory neuron, motor neuron, and effector involved in a reflex form a reflex arc. This is a neural pathway that controls a reflex action in response to a stimulus without conscious thought.
Do stretch reflex have interneuron?
Yes, the stretch reflex involves a simple monosynaptic pathway between sensory neurons and motor neurons without the involvement of interneurons in the spinal cord.
