A reflex arc is a pathway that a nerve impulse follows during a reflex action. Reflex arcs are highly beneficial in situations that require a quick response and do not involve conscious thought. A typical example of a reflex action is the patellar reflex ('knee jerk' response), which occurs when the patellar tendon is tapped.

A reflex arc occurs when the body responds automatically to an outside stimulation. When someone touches a hot surface, the body responds utilizing a reflex arc to remove the body from the high.
Polysynaptic Reflex Arc Diagram Figure 29.1 Diagram Quizlet
A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.
5 Elements of a Reflex Arc
reflex arc, neurological and sensory mechanism that controls a reflex, an immediate response to a particular stimulus. The primary components of the reflex arc are the sensory neurons (or receptors) that receive stimulation and in turn connect to other nerve cells that activate muscle cells (or effectors), which perform the reflex action.

Key Points. Reflexes, or reflex actions, are involuntary, almost instantaneous movements in response to a specific stimulus. Reflex arcs that contain only two neurons, a sensory and a motor neuron, are considered monosynaptic. Examples of monosynaptic reflex arcs in humans include the patellar reflex and the Achilles reflex.
Reflex ARC sensory neuron pathway from stimulus to response outline diagram Neurons, Sensory
A reflex arc refers to the neural pathway that a nerve impulse follows. The reflex arc typically consists of five components: A receptor, and independent sensory cell, or an ending of a sensory neuron, reacts to a stimulus (e.g., a stretch receptor)..

The reflex arc is the pathway that a signal follows from stimulus to response during a reflex action. The typical reflex arc of a simple reflex has seven components, which are shown in Figure 2. Figure 2: A flow chart showing the 7 components of a reflex arc, from the stimulus to the response.

By definition, a reflex is an involuntary, stereotypical response of the effector tissue from the stimulation of receptors. These reflexes are executed by the successive activation of a certain number of neurons that are mutually connected.
The top panel in this figure shows a long reflex, where the spinal cord is connected to the
Draw a labelled diagram of reflex arc and explain reflex action. Solution Verified by Toppr The reflex arc describes the pathway in which the nerve impulse is carried and the response is generated and shown by the effector organ. The reflex arc typically consists of five components: 1. The receptor is present in the receptor organ. 2.

The best known of the reflexes is the patellar, or knee-jerk, reflex. The DTR exam involves a healthcare provider tapping your knee with a rubber hammer (it shouldn't hurt). This tap stretches your patellar tendon and the muscle in your thigh that connects to it. That's how the leg moved on its own. Comment.
