A reflex is a rapid, involuntary response to a stimulus such as a hot stove.
The reflex arc is the pathway traveled by the nerve impulses during a reflex. Most reflexes are pathways that traverse only the spinal cord.
During a spinal reflex, information may be transmitted to the brain, but it is the spinal cord that is responsible. They can happen faster than you can think about it.
A reflex arc involves the following components:
- The receptor is the part of the neuron (usually a dendrite) that detects a stimulus (burn).
- The sensory neuron transmits the impulse to the spinal cord.
- The integration center involves one, two or more synapses 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 form the motor neuron (remove the hand). In somatic reflexes, the effector is skeletal muscle. In autonomic reflexes, the effector is smooth or cardiac muscle, or a gland.

What is the sacral reflex arc?
The sacral reflex arc refers to the neural pathway that controls involuntary responses in the sacral region of the spinal cord. It involves sensory neurons detecting stimuli and transmitting signals to the spinal cord, which then sends motor signals back to the muscles or glands in that region to produce a reflex action. This reflex arc helps regulate functions such as bowel and bladder control.
How does effector relate to reflex arc?
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?
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.
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.
A reflex arc begins with the stimulation of a what?
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.
How hormones function in a reflex arc?
Hormones have nothing to do in reflex arc.

What is the sacral reflex arc?
The sacral reflex arc refers to the neural pathway that controls involuntary responses in the sacral region of the spinal cord. It involves sensory neurons detecting stimuli and transmitting signals to the spinal cord, which then sends motor signals back to the muscles or glands in that region to produce a reflex action. This reflex arc helps regulate functions such as bowel and bladder control.
What are the effectors of a reflex arc?
Muscles and glands are the possible effectors of a reflex arc
What type of neuron begins a reflex arc?
A sensory receptor is the type of neuron that begins a reflex arc.
What kind of reflex arc does not require an inter neuron?
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.
How does effector relate to reflex arc?
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 neural pathway of a single reflex is called?

Is reflex action and reflex arcs are same?
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.

What are the two types of reflex arcs?
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.
