Summarized below are the 5 major components of the reflex arc:
1. Receptor
2. Afferent (sensory) neurons
3. Association neuron
4. Efferent (motor) neurons
5. Effector
An effector is a part of the body (such as a muscle or gland) that carries out the response in a reflex arc. In a reflex arc, when a stimulus is detected by a sensory receptor, a message is sent via a sensory neuron to the spinal cord, where it is processed, and then a message is sent via a motor neuron to the effector causing a response.
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.

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.
A reflex arc begins with the stimulation of a sensory receptor such as those on the skin. The stimulus is then passed as an electrical impulse along sensory, relay and motor neurones (by-passing the brain) before reaching an effector orgen, like a muscle, which then responds to the stimulus.
Five parts of a reflex arc are the receptor, sensory neuron (afferent), integration center, motor neuron (efferent), and effector.
Hormones have nothing to do in reflex arc.

Muscles and glands are the possible effectors of a reflex arc
A sensory receptor is the type of neuron that begins a reflex arc.
A monosynaptic reflex arc does not require an interneuron. In this type of reflex arc, the sensory neuron communicates directly with the motor neuron in the spinal cord or brainstem, resulting in a quick and simple reflex response.
An effector is a part of the body (such as a muscle or gland) that carries out the response in a reflex arc. In a reflex arc, when a stimulus is detected by a sensory receptor, a message is sent via a sensory neuron to the spinal cord, where it is processed, and then a message is sent via a motor neuron to the effector causing a response.
Reflex Arc
what is the role of sensory and motor neurones in a reflex arc
Reflexes are uncontrollable movements that happen almost instantly in response to a stimuli. A reflex arc, a neuronal circuit that controls reflexes, is where reflex activities takes place.
The answer is that the monosynaptic reflex arc links up with the duosynaptic reflex arc and forms a hypothalamus gland and forms a bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb```````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvbbbbbbbbbbbbbbbbbbbbbbbbbb bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbgggggggggggggggggggggggggggggggggggggggggggggggggggggggbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
The two types of reflex arcs are the monosynaptic reflex arc and the polysynaptic reflex arc. A monosynaptic reflex arc involves a direct connection between a sensory neuron and a motor neuron, allowing for a quick response, as seen in the knee-jerk reflex. In contrast, a polysynaptic reflex arc includes one or more interneurons between the sensory and motor neurons, enabling more complex responses and integration of information, such as in withdrawal reflexes.
