Physiological absent response can be due to obesity, frailty, or muscle laxity after multiple pregnancies or abdominal surgery. [1] It is not unusual for this reflex to be absent in children. [2] If the reflex is absent, or especially if it is asymmetric, it can indicate a neurological problem somewhere above the lower thoracic spine. [1]
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 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 ...
In the abdomen, general visceral afferent fibers usually accompany sympathetic efferent fibers. This means that a signal traveling in an afferent fiber will begin at sensory receptors in the afferent fiber's target organ, travel up to the ganglion where the sympathetic efferent fiber synapses, continue back along a splanchnic nerve from the ganglion into the sympathetic trunk, move into a ...
They supply the rectus abdominis and end as the anterior cutaneous branches of the abdomen; they supply the skin of the front of the abdomen. The lower intercostal nerves supply the intercostales and abdominal muscles; the last three send branches to the serratus posterior inferior. About the middle of their course they give off lateral ...
Layers of the Alimentary Canal.The wall of the alimentary canal has four basic tissue layers: the mucosa, submucosa, muscularis, and serosa. The enteric nervous system in humans consists of some 500 million neurons [11] (including the various types of Dogiel cells), [1] [12] 0.5% of the number of neurons in the brain, five times as many as the one hundred million neurons in the human spinal ...
This region of the abdomen contains part of the stomach, the head of the pancreas, the duodenum, a section of the transverse colon and the lower aspects of the left and right kidney. The upper three regions, from left to right, are the left hypochondriac, epigastric, and right hypochondriac regions.
An abdominal muscle strain, also called a pulled abdominal muscle, is an injury to one of the muscles of the abdominal wall. A muscle strain occurs when the muscle is stretched too far. When this occurs the muscle fibers are torn. Most commonly, a strain causes microscopic tears within the muscle, but occasionally, in severe injuries, the ...
