there are 2 - one between the sensory and relay neurones; the other between the relay and motor neurones.

How does effector relate to reflex arc?
An effector is at the end of a reflex arc as it is the muscle or gland that 'does' the reflex. What the effector does is the outcome of the reflex arc.
Reflexes are not carried to the brain?
A reflex arc does not pass through the brain. The somatic reflex arc and autonomic reflex arc are two types.
What is the function of reflex arc?
The reflex arc allows sensory neurons to synapse in the spinal cord instead of the brain, allowing actions to occur relatively quickly by activating spinal motor neurons without needing to send signals through the brain. For example, a person touching a hot stove would flinch before thinking about it, and protect tissues from further damage.
What controls reflex actions?
spinal cordautotomicspinal cord in the central nervous system controls reflex arc and reflex action.
How might damage to the spine affect a reflex arc?
Damage to the spine can affect the reflex arc by delaying the nerve pathway or making it so you are unable to move a muscle.
How many synapses are crossed in a single reflex arc during a muscle stretch reflex?
one
Which component of a reflex arc is located entirely within the central nervous system?
Many authors refer to the CNS portion of the reflex arc as the integration center.In regards to a monosynaptic reflex arc, the synapse is the only portion of the integration center.Polysynaptic reflex arcs, have multiple synapses and interneuron(s).
How many synapses are in a polysynaptic reflex arc containing 2 interneurons in the integrating center?
3 because there are regularly 2 synapses when there is only one interneuron. An extra neuron will add an extra synapse.
What is the speed of conduction through a reflex arc slower than the speed of conduction of an action potential along an axon?
First, do you're own anatomy homework in the future. Second, the number of synapses effects the overall time it takes for the signal to go through the reflex arc.
How does effector relate to reflex arc?
An effector is at the end of a reflex arc as it is the muscle or gland that 'does' the reflex. What the effector does is the outcome of the reflex arc.
How hormones function in a reflex arc?
Hormones have nothing to do in reflex arc.
What is the pathway of reflex?
reflex arc
What are the effectors of a reflex arc?
Muscles and glands are the possible effectors of a reflex arc
Reflexes are not carried to the brain?
A reflex arc does not pass through the brain. The somatic reflex arc and autonomic reflex arc are two types.
What type of neuron begins a reflex arc?
A sensory receptor is the type of neuron that begins a reflex arc.
First step in a reflex arc?
A reflex arc involves the following components:The receptor is the part of the neuron (usually a dendrite) that detects a stimulus.The sensory neuron transmits the impulse to the spinal cord.The integration center involves one synapse (monosynaptic reflex arc) or two or more synapses (polysynaptic reflex arc) in the gray matter of the spinal cord.A motor neuron transmits a nerve impulse from the spinal cord to a peripheral region.An effector is a muscle or gland that receives the impulse from the motor neuron. In somatic reflexes, the effector is skeletal muscle. In autonomic (visceral) reflexes, the effector is smooth or cardiac muscle, or a gland.
What is the neural pathway of a single reflex called?
Reflex Arc
