The Lumbar Spine refers to the bottom six vertebrae in the spine. Most strain on the Lumbar spine occur between L4 and L6, where the back bows. This forces blood from the rest of the back to flow over to even-out the blood flow in the back. Therefore, the small of the back has minimal blood flow, making a puncture easier.
in adults its done at L3 and L4 or L4 and L5

A lumbar puncture, also known as a spinal tap, is typically performed in a hospital, clinic, or doctor's office. It is done in a sterile procedure room by a healthcare provider such as a doctor or nurse.
Small slits or holes are poked in lumber when it is incised. It is done before treating the lumber with chemicals. Some lumber does not require incising. Lumber that doesn't require incising are Southern softwoods. Incising does effect the ultimate strength of the lumber, but not by much, say 2 to 5%. It is still considered a good trade off if the lumber is having additional value added treatments.
A lumbar puncture is generally performed in the lower back, between the third and fourth or fourth and fifth lumbar vertebrae. This location allows easier access to the cerebrospinal fluid in the subarachnoid space without risk of damaging the spinal cord.
I think you mean level of the vertebral column is a lumbar puncture generally performed?
The dura (sack containing the spinal cord and also the spinal fluid) is surrounded by the epidural space. So, when placing a lumbar puncture needle ("spinal" needle) successively through: the skin of the lower back, the underlying fat, the ligaments that run vertically between the spinous processes of the spine, it will have to go across the epidural space, then puncture the dura and enter the spinal fluid, a few milliliters of which is then sent for laboratory testing.

A sternal puncture is typically done at an angle of 45 degrees to avoid injury to underlying structures and to ensure proper access to the bone marrow for aspiration or biopsy in diagnostic procedures.
Since it is right under your ribs, 2 inches would be enough to puncture it, but 6 would get the job done better.
Arthrocentesis is the term meaning surgical puncture of a joint. This procedure is usually done to remove fluid for analysis or to increase comfort.
The primary purpose of stack lumber is to facilitate the dying process and to take away the moisture from the board surface quicker. If the stack lumber is not done right it can lose some of it value.
