The rolling of the dorsal, lumbar region of skin is instigated by the skeletal muscle (cutaneous trunci). This muscle is located directly under the skin and is hyperresponsive when scratched, which thereby causes the rippling effect.
A list of reflexes in humans. Abdominal reflex; Accommodation reflex — coordinated changes in the vergence, lens shape and pupil size when looking at a distant object after a near object. Acoustic reflex or attenuation reflex — contraction of the stapedius and tensor tympani muscles in the middle ear in response to high sound intensities.
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.
Tripping Activates Cutaneous Reflex. Cutaneous, superficial, [1] or skin reflexes, are activated by skin receptors and play a valuable role in locomotion, providing quick responses to unexpected environmental challenges. They have been shown to be important in responses to obstacles or stumbling, in preparing for visually challenging terrain ...
The peripheral nervous system (PNS) is divided into the somatic nervous system, the autonomic nervous system, and the enteric nervous system.However, it is the somatic nervous system, responsible for body movement and the reception of external stimuli, which allows one to understand how cutaneous innervation is made possible by the action of specific sensory fibers located on the skin, as well ...
WASHINGTON (Reuters) -The Trump transition team is considering a former Uber executive and three current or former Republican congressmen - one of whom is now a Fox News host - to lead the U.S ...
There are two frequently used placing reflexes. They are tests which allow clinicians to assess the proprioceptive abilities of small domestic animals (cats and dogs in particular). The first test is to lift an animal and bring the anterior/dorsal surface of a paw up to a table edge. The normal animal will position its paw onto the surface ...
