Reflexes - Physiopedia
Reflexes are the body’s intrinsic stimulus-response systems for maintaining homeostasis, and when performed and interpreted correctly are the most objective evidence within the neurological screen to localise the lesion to specific structures within the nervous system.
Deep Tendon Reflexes - Stanford Medicine 25
There are five deep tendon reflexes and a number of superficial and visceral reflexes covered here. The reflex exam is fundamental to the neurological exam and important to locating upper versus lower motor neuron lesions.

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.
Reflex | Physiology, Definition, Types & Examples | Britannica
Reflexes include not only such simple acts as chewing, swallowing, blinking, the knee jerk, and the scratch reflex, but also stepping, standing, and mating. Built up into complex patterns of many coordinated muscular actions, reflexes form the basis of much instinctive behaviour in animals.
Reflexes – Basic Human Physiology
Define the term reflex. Describe reflex responses in terms of the major structural and functional components of a reflex arc. Distinguish between each of the following pairs of reflexes: intrinsic versus learned, somatic versus visceral, and ipsilateral versus contralateral.
Reflexes – Boundless Anatomy and Physiology
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.
Reflex actions - Human nervous system - Encyclopedia Britannica
The term is now used to describe an action that is an inborn central nervous system activity, not involving consciousness, in which a particular stimulus, by exciting an afferent nerve, produces a stereotyped, immediate response of muscle or gland. The …
Reflex | A Simplified Psychology Guide
Reflexes help the body respond quickly to potential threats or dangers without having to consciously think about the appropriate response. They are important for maintaining balance, protecting vital organs, and ensuring the body’s overall well-being.
