An abdominal reflex is a superficial neurological reflex stimulated by stroking of the abdomen around the umbilicus. It can be helpful in determining the level of a central nervous system (CNS) lesion. Being a superficial reflex, it is polysynaptic (involving multiple connections between nerves). [1]
The epigastrium is the part of the abdomen where abdominal thrusts (the Heimlich manoeuvre) are able to produce a rapid and forceful exhalation of breath. [citation needed] Palpation of the epigastrium can be used to feel the structures below it. [2] This includes the liver, and the stomach. [2] An aortic aneurysm may be felt as a mass in the ...
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.
In medicine, Murphy's sign (also known as Sweeney’s sign) is a maneuver during a physical examination as part of the abdominal examination. [1] It is useful for differentiating pain in the right upper quadrant. Typically, it is positive in cholecystitis, but negative in choledocholithiasis, pyelonephritis, and ascending cholangitis.
McBurney's point is located one third of the distance from the right anterior superior iliac spine to the umbilicus (navel). [1] [2] This point roughly corresponds to the most common location of the base of the appendix, where it is attached to the cecum. [3] Normal location of the appendix relative to other organs of the digestive system ...
Mucus is released in the stomach and intestine, and serves to lubricate and protect the inner mucosa of the tract. It is composed of a specific family of glycoproteins termed mucins and is generally very viscous. Mucus is made by two types of specialized cells termed mucous cells in the stomach and goblet cells in the intestines. Signals for ...
The vagovagal reflex is active during the receptive relaxation of the stomach in response to swallowing of food (prior to it reaching the stomach). When food enters the stomach a "vagovagal" reflex goes from the stomach to the brain, and then back again to the stomach causing active relaxation of the smooth muscle in the stomach wall.
Rovsing's sign, named after the Danish surgeon Niels Thorkild Rovsing (1862–1927), [1] is a sign of appendicitis.If palpation of the left lower quadrant of a person's abdomen increases the pain felt in the right lower quadrant, the patient is said to have a positive Rovsing's sign and may have appendicitis.
