Why is it called Transpyloric plane?

The transpyloric plane (also called the transpyloric line) is one of the surface reference lines used in surface anatomy. … This plane also passes through the origin of the superior mesenteric artery, the body of the gallbladder, and of course through the pylorus of the stomach, from whence the name of this plane arises.

What is Stomachbed?

The stomach bed refers to the structures upon which the stomach rests in mammals. These include the pancreas, spleen, left kidney, left suprarenal gland, transverse colon and its mesocolon, and the diaphragm. The term was introduced around 1896 by Philip Polson of the Catholic University School of Medicine, Dublin.

Where is the Transtubercular plane?

A lower transverse line 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.

How do you split your stomach into 9 regions?

divided into 9 regions by two vertical and two horizontal imaginary planes. … Four abdominal quadrants

  1. right upper quadrant fossa (RUQ)
  2. right lower quadrant fossa (RLQ)
  3. left lower quadrant fossa (LLQ)
  4. left upper quadrant fossa (LUQ)

What is at the level of L1?

As the first vertebra in the lumbar region, the L1 vertebra bears the weight of the upper body and acts as a transition between the thoracic and lumbar vertebrae. The L1 vertebra is located in the spinal column of the lumbar (lower back) region inferior to the T12 vertebra and superior to the L2 vertebra.

How do you identify the 9th costal cartilage?

The xiphoid. The costal margin extends from the 7th costal cartilage at the xiphoid to the tip of the 12th rib (although the latter is often difficult to feel); this margin bears a distinct step, which is the tip of the 9th costal cartilage.

What is duodenal point?

The duodenum is the first part of the small intestine (5-7 m), followed by the jejunum and ileum (in that order); it is also the widest and shortest (25 cm) part of the small intestine. The duodenum is a C-shaped or horseshoe-shaped structure that lies in the upper abdomen near the midline (see the image below). [ 1 ,2 ]

Which line divides the body into right and left halves?

Sagittal Plane Sagittal Plane The sagittal plane divides the body vertically into equal right and left halves. This plane is also referred to as the midsagittal plane because it is on the midline of the body. Movements within the sagittal plane are flexion and extension forward and backward movements of the head, spine, and limbs.

What vertebral level is gallbladder?

The lowest point of the gallbladder, according to Eycleshymer and Schoemaker, varies from the upper third of the twelfth thoracic vertebra to the upper third of the fourth lumbar vertebra. The average position is at the level of the lower third of the second lumbar vertebra.

Which body plane could be used to separate the stomach from the liver?

coronal plane coronal plane: Any vertical plane that divides the body into anterior and posterior (belly and back) sections.

Is the Oesophagus retroperitoneal?

Retroperitoneal organs lie behind the posterior sheath of the peritoneum and include the aorta, esophagus, second and third parts of the duodenum, ascending and descending colon, pancreas, kidneys, ureters, and adrenal glands.

How is linea alba formed?

The Linea Alba. The linea alba is a tendinous raph in the middle line of the abdomen, stretching between the xiphoid process and the symphysis pubis. It is placed between the medial borders of the Recti, and is formed by the blending of the aponeuroses of the Obliqui and Transversi.

Where is Subcostal?

The subcostal muscle has variable anatomy and forms part of the intercostal muscle group. It lies on the deep surface of the innermost intercostal muscle in the posterior chest, near the angles of the ribs, usually running over 2-3 intercostal spaces.

What is the costal margin?

Costal margin: The lower edge of the chest (thorax), formed by the bottom edge of the rib cage.

What is Subcostal area?

subcostal plane [TA] a transverse plane passing through the inferior limits of the costal margin, that is, the tenth costal cartilages; it marks the boundary between the hypochondriac and epigastric regions superiorly and the lateral and umbilical regions inferiorly.

Is your pancreas above your belly button?

Located directly behind the stomach, the pancreas lies deep in the center of the abdomen. Its position corresponds to an area 3-6 inches above the belly button, straight back on the back wall of the abdominal cavity. In fact, the bones of the spine are just a few inches behind the pancreas.

What is the size of a normal stomach?

Most adults have roughly the same size stomach, even though people can weigh different amounts. Your empty stomach is about 12 inches long by 6 inches across at its widest point. As an adult, your stomach can expand to hold about 1 quart of food.

What is peritoneal lining?

Anatomical terminology. The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. It covers most of the intra-abdominal (or coelomic) organs, and is composed of a layer of mesothelium supported by a thin layer of connective tissue.

What are the 3 planes of the body?

The three planes of motion are the sagittal, frontal and transverse planes.

  • Sagittal Plane: Cuts the body into left and right halves. Forward and backward movements.
  • Frontal Plane: Cuts the body into front and back halves. Side-to-side movements.
  • Transverse Plane: Cuts the body into top and bottom halves.

The transtubercular plane (also called the transtubercular line) is one of the surface reference lines used in surface anatomy to delineate the abdominal regions. It is a horizontal or transverse plane that passes through the iliac tubercles, small elevations found in the iliac crest of the iliac bone.
