abdominal r's the areas into which the anterior surface of the abdomen is divided, including the epigastric, hypochondriac (right and left), iliac (right and left), lumbar (right and left), hypogastric, and umbilical.

Nine abdominopelvic regions. From Applegate, 2000.

See illustration.

AN region the area of the heart where the atrial fibers merge with the atrioventricular node.

anal region the part of the perineal region that surrounds the anus.

axillary region the area of the upper chest surrounding the axilla, lateral to the pectoral region.

epigastric region the abdominal region that is superior and central in location, above the umbilical region and between the two hypochondriac regions.

hypochondriac region either of the abdominal regions that are in superior lateral locations, one on the left (left hypochondriac region) and one on the right (right hypochondriac region) of the epigastric region; called also hypochondrium.

hypogastric region suprapubic region.

I region that part of the major histocompatibility complex where immune response genes are present.

iliac region inguen.

inframammary region the part of the pectoral region inferior to the breast, bordered inferiorly by the hypochondriac region of the abdomen.

inguinal region inguen.

lateral region either of the abdominal regions that are in central lateral locations, one to the left (left lateral region) and one to the right (right lateral region) of the umbilical region; called also flank and lumbar region.

lateral pectoral region the most lateral part of the pectoral region, bounded laterally by the axillary region.

lumbar region

1. the region of the back lying lateral to the lumbar vertebrae. See also loin.

2. lateral region.

mammary region the part of the pectoral region surrounding the mammary gland.

N region [nodal region] the region of the atrioventricular node consisting of the body of the node.

NH region [nodal-His region] the area where the atrioventricular node becomes the bundle of His.

pectoral region the aspect of the chest overlying the pectoralis major muscle, subdivided into the lateral pectoral, mammary, and inframammary regions.

pelvic region suprapubic region.

perineal region the region underlying the pelvic outlet, subdivided into the anal and urogenital regions.

precordial region the part of the anterior surface of the body covering the heart and the pit of the stomach.

presternal region the region of the thorax overlying the sternum, bounded laterally by the pectoral regions.

pubic region suprapubic region.

suprapubic region the abdominal region that is inferior and central in location, below the umbilical region and between the two iliac(inguinal) regions; called also hypogastric or pelvic region.

umbilical region the abdominal region that is most central in location, surrounding the umbilicus; it is bounded laterally by the two lateral or lumbar regions, superiorly by the epigastric region, and inferiorly by the suprapubic or hypogastric region.

urogenital region the part of the perineal region that surrounds the external genital organs and the urethral orifice,

ABDOMINAL REGIONS

abdominal regions

The abdomen and its external surface, divided into nine regions by four imaginary planes: two horizontal, one at the level of the ninth costal cartilage (or the lowest point of the costal arch) and the other at the level of the highest point of the iliac crest; two vertical, through the centers of the inguinal ligaments (or through the nipples or through the centers of the clavicles) or curved and coinciding with the lateral borders of the two abdominal rectus muscles.

See: illustration

chest region

Any of the three areas of the chest: anterior, posterior, and lateral. The anterior divisions (right and left) are the clavicular, infraclavicular, and supraclavicular, the mammary and inframammary, and the upper and lower sternal. The posterior divisions (right and left) are the scapular, infrascapular, interscapular, and suprascapular. The lateral divisions are the axillary and infra-axillary.

hypochondriac region

Hypochondrium.

hypogastric region

Hypogastrium.

iliac region

lumbar region

That area of the abdominal surface lateral to the umbilical region, above the iliac region, and below the hypochondriac region.

Patient discussion about region

Q. Any idea on how to meet people who suffer from alcoolism in my region?

A. if you look for an AA meeting near your home- that should not be a problem- just "google" it. or ask your doctor to reffer you to the nearest clinic.
take care! and good for you on that big step!

Q. Is there any problem, if an arachnoid cyst ,2cmx1.5cm size, rostral to cerebellar region left untreated? symptoms: repeated headaches, twitching of muscles, tiredness

A. An arachnoid cyst that leads to symptoms usually needs treatment. Mild symptoms as you suggested are ok to left untreated however gradual onset of new symptoms may arise such as seizures, paralysis and other complications, therefore once symptoms occur one should consider treatment.

Q. experiencing sharp pain in my right kidney region... pain is acute and doesnt radiate... recently PE left lung have been taking warfrin, panadiene forte, two kinds of cholesterol/triglycerine reducing meds and champix quit smoking medication... recently tests showed the hight cholesterol and triglys' levels and also a swollen liver... pain is not in my liver area... past pain in this kidney recurrent but never as bad. always dull.. many years ago had a uti, which caused high protiene levels.. very bad at finishing anti-biotics... recently had tonsilitis.. This hurts and is tender to touch but does not bring on sharp pain when touched, sharp pain comes and goes after taking pain relief

A. Go to see a doctor - although its tempting to make the diagnosis over the net (I have several ideas about what it might be), it sounds like serious, especially if you had a PE lately - it could be a thrombus in the vein of the kidney, or maybe a stone (sounds like that according to the description of the pain). However, as I said, making the diagnosis without even seeing you isn't the wisest thing to do.

Take care,
