The chin is referred to as the mental region. The neck is referred to as the cervical region. The trunk of the body contains, from superior to inferior, the thoracic region encompassing the chest [1] the mammary region encompassing each breast; the sternal region encompassing the sternum; the abdominal region encompassing the stomach area
On the sides of the abdomen the other six regions are the left and right hypochondriac regions, on either side of the epigastrium; the left and right lumbar flank regions, on either side of the umbilical region, and the left and right iliac or inguinal regions on either side of the hypogastrium.

This difference, and because the lumbar spines of the extinct Nacholapithecus (a Miocene hominoid with six lumbar vertebrae and no tail) are similar to those of early Australopithecus and early Homo, it is assumed that the chimpanzee–human last common ancestor also had a long vertebral column with a long lumbar region and the reduction in the ...
The lumbar region is sometimes referred to as the lower spine, or as an area of the back in its proximity.. In human anatomy the five lumbar vertebrae (vertebrae in the lumbar region of the back) are the largest and strongest in the movable part of the spinal column, and can be distinguished by the absence of a foramen in the transverse process, and by the absence of facets on the sides of the ...
The regions are the left and right hypochondriac regions, so named because they lie under the ribs; the epigastric region which is approximately where the stomach is located between the hypochondriac regions; the right and left lumbar regions which flank the umbilical region (which surrounds the umbilicus, or belly button), the right and left ...
The lumbar (or lower back) region is the area between the lower ribs and gluteal fold which includes five lumbar vertebrae (L1–L5) and the sacrum. In between these vertebrae are fibrocartilaginous discs, which act as cushions, preventing the vertebrae from rubbing together while at the same time protecting the spinal cord.
It is sometimes called the lumbar region. References This page was last edited on 15 December 2023, at 01:53 (UTC). Text is available under the Creative ...
In anatomy, lumbar is an adjective that means of or pertaining to the abdominal segment of the torso, between the diaphragm and the sacrum (pelvis). The five vertebrae in the lumbar region of the back are the largest and strongest in the spinal column. In most mammals, the lumbar region of the spine curves outward; this is called lordosis. Date
