The patellar reflex, also called the knee reflex or knee-jerk, is a stretch reflex which tests the L2, L3, and L4 segments of the spinal cord. Many animals, most significantly humans, have been seen to have the patellar reflex, including dogs, cats, horses, and other mammalian species.
Hoffmann's reflex (Hoffmann's sign, sometimes simply Hoffmann's, or finger flexor reflex) [1] is a neurological examination finding elicited by a reflex test which can help verify the presence or absence of issues arising from the corticospinal tract. It is named after neurologist Johann Hoffmann. [2]
Hering–Breuer reflex — is a reflex triggered to prevent over-inflation of the lung; Hoffmann's reflex — also known as the finger flexor reflex; middle finger and thumb response. Test can indicate both neurological damage and nerve regeneration; often combined with the Babinski reflex test. Jaw jerk reflex
For example, a majority of dogs will exhibit the reflex when scratched with fingernails, while only some with a stronger reflex might react to a lighter tapping. Allergies and itchiness often play a role in the scratch reflex, with dogs who are already itchy before the additional stimulation often producing a stronger reflex than other dogs.
The crossed extensor reflex is contralateral, meaning the reflex occurs on the opposite side of the body from the stimulus. To produce this reflex, branches of the afferent nerve fibers cross from the stimulated side of the body to the contralateral side of the spinal cord.
My unsuspecting German shepherd mix, Daisy, helped me test out four different dog DNA kits to find the best one. All instructions were followed closely, with the exception of required swabbing times.
The tail flick assay or tail flick test uses a high-intensity beam of light aimed at a rodent's tail to detect nociception. [1] In normal rodents, the noxious heat sensation induced by the beam of light causes a prototypical movement of the tail via the flexor withdrawal reflex. [2]
The normal animal will position its paw onto the surface properly. The second (sometimes called the proprioceptive positioning reflex) is similar. The dorsal (top) surface of an animals paw is placed onto a surface, and a fully healthy animal would flick it back up to be in the normal position (dorsal side up).
