Question

A scheme used the abdominal surface and the abdominopelvic cavity into four approximately equal regions called quadrants. These quadrants are named according to their relative position- that is, right upper quadrant, right lower quadrant, left upper quadrant, and left lower quadrant (Figure 1.8). Note that the terms left and right refer to the left and right side of the body in the figure, not the left and right side of the art on the page. The left and right of the figure are referred to as anatomical left and right. Examine the human torso model to respond to the following Right lower questions. Name two organs found in the left upper quadrant. _____ and _____ Name two organs found in the right lower quadrant. _____ and _____ What organ (Figure 1.8) is divided into identical halves by the median plane?_____ A different scheme commonly used by anatomists divides the abdominal surface and abdominopelvic cavity into nine separate regions by four planes (Figure 1.9). Although the names of these nine regions are unfamiliar to you now, with a little patience and study they will become easier to remember. As you read through the descriptions of these nine regions, locate them (Figure 1.9), and note the organs contained in each region. Umbilical region: The centermost region, which includes the umbilicus (navel) Epigastric region: Immediately superior to the umbilical region: overlies most of the stomach Hypogastric (pubic) region: Immediately inferior to the umbilical region: encompasses the pubic area Iliac, or inguinal, regions: Lateral to the hypogastric region and overlying the superior parts of the hip bones Lumbar regions: Between the ribs and the flaring portions ties contain of the hip bones: lateral to the umbilical region Hypochondriac regions: Flanking the epigastric region laterally and overlying the lower ribs
