Median Plane
Whether in reference to the anatomy of the human or other members of the Bilateria, the median plane, also called the midsagittal plane and related terms, is used to describe the sagittal plane as it bisects the body vertically through the midline marked by the navel, dividing the body exactly in left and right side. The term parasagittal plane is used to refer to any plane parallel to the sagittal and median plane. It is one of the lines used to define the right upper quadrant of the human abdomen. The midsternal line can be interpreted as a segment of the median plane. File:Sagittal brain MRI.jpg, Median plane magnetic resonance imaging of the head.

Trans Tubercular Plane
A lower transverse plane midway between the upper transverse and the upper border of the pubic symphysis; this is termed the intertubercular plane (or transtubercular), since it practically corresponds to that passing through the iliac tubercles; behind, its plane cuts the body of the fifth lumbar vertebra.

Transpyloric Plane
The transpyloric plane, also known as Addison's plane, is an imaginary transverse plane, horizontal plane, located halfway between the suprasternal notch of the manubrium and the upper border of the symphysis pubis at the level of the first lumbar vertebrae, L1. It lies roughly a hand's breadth beneath the xiphisternum or midway between the xiphisternum and the navel, umbilicus. The plane in most cases cuts through the pylorus of the stomach, the tips of the ninth costal cartilages and the lower border of the first lumbar vertebra. Structures crossed The transpyloric plane is clinically notable because it passes through several important abdominal structures. It also divides the Supracolic compartment, supracolic and infracolic compartments, with the liver, spleen and gastric fundus above it and the small intestine and colon below it. Lumbar vertebra and spinal cord The lower border of first Lumbar vertebrae, lumbar vertebra lies at the level of the transpyloric plane, according ...

Transverse Plane
A transverse plane is a plane that is rotated 90° from two other planes. Anatomy The transverse plane is an anatomical plane that is perpendicular to the sagittal plane and the dorsal plane. It is also called the axial plane or horizontal plane, especially in human anatomy, but horizontal plane can be misleading with other animals. The plane splits the body into a cranial (head) side and caudal (tail) side, so in humans the plane will be horizontal (dividing the body into superior and inferior sections) but in quadrupeds it will be vertical.

Costal Margin
The costal margin, also known as the costal arch, is the lower edge of the chest (thorax) formed by the bottom edge of the rib cage. Structure The costal margin is the medial margin formed by the cartilages of the seventh to tenth ribs. It attaches to the body and xiphoid process of the sternum. The thoracic diaphragm attaches to the costal margin. The costal angle is the angle between the left and right costal margins where they join the sternum. Function The costal margins somewhat protect the higher abdominal organs, such as the liver. Clinical significance The costal margin may be used for tissue harvesting of cartilage for use elsewhere in the body, such as to treat microtia. Different abdominal organs may be palpated just below the costal margin, such as the liver on the right side of the body. Pain across the costal margin is most commonly caused by costochondritis. The costal paradox, also known as Hoover's sign and the costal margin paradox, is a sign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lumbar Vertebrae
The lumbar vertebrae are located between the thoracic vertebrae and pelvis. They form the lower part of the back in humans, and the tail end of the back in quadrupeds. In humans, there are five lumbar vertebrae. The term is used to describe the anatomy of humans and quadrupeds, such as horses, pigs, or cattle. These bones are found in particular cuts of meat, including tenderloin or sirloin steak. Human anatomy In human anatomy, the five vertebrae are between the rib cage and the pelvis. They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the thoracic region). They are designated L1 to L5, starting at the top. The lumbar vertebrae help support the weight of the body, and permit movement. General characteristics The adjacent figure depicts the general cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inferior Mesenteric Artery
In human anatomy, the inferior mesenteric artery (IMA) is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal. The regions supplied by the IMA are the descending colon, the sigmoid colon, and part of the rectum. Structure Origin The IMA arises from the anterior aspect of the abdominal aorta. Its origin is situated at the L3 vertebral level ( subcostal plane), below the origins of the two renal arteries, 3-4 cm above the aortic bifurcation, at the level of the umbilicus, and posterior to the inferior border of the horizontal (III) part of the duodenum. Branches Along its course, the IMA has the following branches: All these arterial branches further divide into arcades which then supply the colon at regular intervals. Relations The IMA is accompanied along its course by a similarly named vein, the inferior mesenteric vein, which drains into the ...

Quadrants And Regions Of Abdomen
The human abdomen is divided into quadrants and regions by anatomy, anatomists and physicians for the purposes of study, medical diagnosis, diagnosis, and therapy, treatment. The division into four quadrants allows the localisation of pain and tenderness (medicine), tenderness, scars, lumps, and other items of interest, narrowing in on which organ (anatomy), organs and tissue (biology), tissues may be involved. The quadrants are referred to as the left lower quadrant, left upper quadrant, right upper quadrant and right lower quadrant. These terms are not used in comparative anatomy, since most other animals do not stand erect. The left lower quadrant includes the left iliac fossa and half of the Flank (anatomy), flank. The equivalent in other animals is ''left posterior quadrant''. The left upper quadrant extends from the umbilical plane to the left ribcage. This is the ''left anterior quadrant'' in other animals. The right upper quadrant extends from umbilical plane to the right ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supracristal Plane
Supracristal plane (''Planum supracristale'') (or supracrestal plane) is an anatomical transverse plane lying at the upper most part of the pelvis, the iliac crest. According to Gray's Anatomy, this anatomical plane crosses the upper border of the spinous process of L4 (fourth lumbar vertebra). It passes through the umbilical region and the left and right lumbar regions. Clinical significance The supracristal plane can be used as a landmark for several nerve branches, as well as an approximate marker for the umbilicus (belly button). It is also used as the divider between the lower (left and right) and upper (left and right) quadrants of the abdomen (where the vertical midline divides left from right). It is also the level where the abdominal aorta bifurcates into the left and right common iliac artery and just superior to the union of the common iliac veins. It can help in the identification of the level of L3/L4 where a lumbar puncture can be done safely. See also * Intertu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A lower transverse plane midway between the upper transverse and the upper border of the pubic symphysis; this is termed the intertubercular plane (or transtubercular), since it practically corresponds to that passing through the iliac tubercles; behind, its plane cuts the body of the fifth lumbar vertebra.
