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.
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.
The patellar reflex (knee jerk) is an example of the stretch reflex and it is used to determine the sensitivity of the stretch reflex. Reflexes can be tested as part of a neurological examination, often if there is an injury to the central nervous system. To test the reflex, the muscle should be in a neutral position.
The Hannington-Kiff sign is a clinical sign in which there is an absent adductor reflex in the thigh in the presence of a positive patellar reflex.It occurs in patients with an obturator hernia, due to compression of the obturator nerve.
The definitive treatment for pre-eclampsia is the delivery of the baby and placenta, but danger to the mother persists after delivery, and full recovery can take days or weeks. [13] The timing of delivery should balance the desire for optimal outcomes for the baby while reducing risks for the mother. [15]
Preeclampsia superimposed on chronic hypertension occurs when a pregnant woman with chronic hypertension develops signs of pre-eclampsia, typically defined as new onset of proteinuria ≥30 mg/dL (1+ in the dipstick) in at least 2 random urine specimens that were collected ≥4 h apart (but within a 7-day interval) or 0.3 g in a 24-h period. [19]
Eclampsia is the onset of seizures (convulsions) in a woman with pre-eclampsia. Pre-eclampsia is a disorder of pregnancy in which there is high blood pressure and either large amounts of protein in the urine or other organ dysfunction. Pre-eclampsia is routinely screened for during prenatal care. Onset may be before, during, or rarely, after ...
Grasp reflex of a 5 month old baby. The palmar grasp reflex appears at birth and persists until five or six months of age. When an object is placed in the infant's hand and strokes their palm, the fingers will close and they will grasp it with a palmar grasp. To best observe this reflex, on a bed where the child could safely fall onto a pillow ...
