supraorbital pressure - this is the manual stimulation of the supraorbital nerve by pressing a thumb into the indentation above the eye, near the nose. [ 2 ] sternal rub - this involves creating a turning pressure (akin to a grinding motion with a pestle and mortar) on the patient's sternum [ 1 ]
Compression of a trigger point may elicit local tenderness, referred pain, or local twitch response. The local twitch response is not the same as a muscle spasm. This is because a muscle spasm refers to the entire muscle contracting whereas the local twitch response also refers to the entire muscle but only involves a small twitch, no contraction.
Merkel nerve endings provide information on pressure, position, and deep static touch features such as shapes and edges. They are tactile sensors in the business of mechanotransduction . They encode surface features of touched objects into perception, but also have to do with proprioception .
The Slowly Adapting type 1 (SA1) mechanoreceptor, with the Merkel corpuscle end-organ (also known as Merkel discs) detect sustained pressure and underlies the perception of form and roughness on the skin. [1] They have small receptive fields and produce sustained responses to static stimulation.
Pressure points [a] derive from the supposed meridian points in Traditional Chinese Medicine, Indian Ayurveda and Siddha medicine, and martial arts. They refer to areas on the human body that may produce significant pain or other effects when manipulated in a specific manner.
Effector muscle innervated by the efferent nerve fiber carries out the response. A reflex arc, then, is the pathway followed by nerves which (a.) carry sensory information from the receptor to the spinal cord, and then (b.) carry the response generated by the spinal cord to effector organs during a reflex action.
Babinski reflex — in infants up to one year of age, and also in older individuals with neurological damage, a spreading of the toes and extension of the big toe in response to stroking the side of the foot. Bainbridge reflex - increasing heart rate in response to increased central venous pressure.
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
