Reflexes - Physiopedia
A reflex is an involuntary and nearly instantaneous movement in response to a stimulus. The reflex is an automatic response to a stimulus that does not receive or need conscious thought as it occurs through a reflex arc. Reflex arcs act on an impulse …
Reflexes – Basic Human Physiology
Describe the following reflexes and name all components of each reflex arc: stretch reflex, (Golgi) tendon reflex, flexor (withdrawal) reflex, and crossed-extensor reflex. Reflexes can be spinal or cranial, depending on the nerves and central components that are involved.
Reflex - Wikipedia
A reflex occurs via neural pathways in the nervous system called reflex arcs. A stimulus initiates a neural signal, which is carried to a synapse. The signal is then transferred across the synapse to a motor neuron, which evokes a target response.

Reflexes – Boundless Anatomy and Physiology
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.

Reflexes can also be classified in terms of the number of neurons or synapses between the primary afferent neuron and the motor neuron. We distinguish two types, the monosynaptic reflex and the much more common multisynaptic or polysynaptic reflex.

Reflex, in biology, an action consisting of comparatively simple segments of behaviour that usually occur as direct and immediate responses to particular stimuli uniquely correlated with them. Many reflexes of placental mammals appear to be innate.
