The midaxillary line is an imaginary vertical line that runs through the midaxillary region of the body, which is located midway between the anterior and posterior axillary lines. It is commonly used as a reference point in anatomy for assessing the location of structures or performing medical examinations.
The left midaxillary region is a specific anatomical area located on the left side of the body, in line with the armpit (axilla) and extending vertically down the side of the chest. It is commonly used as a reference point in medical examinations and procedures to describe the location of organs, structures, or pain. This region is important for clinicians to accurately assess and diagnose conditions affecting the thorax and abdomen.
The seventh intercostal space is located between the seventh and eighth ribs on the side of the body. It can be found laterally along the midaxillary line, which is an imaginary vertical line that runs down the side of the torso.

from what I've read its the following mid clavicular = 5-7 mid axillary = 7-9 paravetebral = 9-11 i believe that it is the second in the midclavicular and either 6,7, or 8 in he midaxillary
