Usually between L2-L3 or L3-L4.
You have the convex anteriorly curve of cervical vertebrae. You have the concave anteriorly curve of thoracic vertebrae. Again you have the convex anteriorly curve of lumber vertebrae. The sacrum goes steep backward from the last lumber vertebra. Here no curve is described probably. So you have lardosis of cervical and lumber vertebrae. You have kyphosis of the thoracic vertebrae.
There isextension of brain in neck, thorax and abdomen in what is called as vertebral column. You have seven cervical vertebrae, twelve thoracic vertebrae and five lumber vertebrae fallowed by sacrum.In between them, you have inter-vertebral disc and various ligaments. Which keep them in position. In the hollow part of these vertebrae, there is spinal cord. It extends to the lower border of second lumber vertebrae. Down to it, there is bundle of nerves called as cauda-equina.
The time it takes for lumber to air dry can vary depending on factors such as the species of wood, its thickness, humidity levels, and ambient temperature. Generally, it can take several months to a year for lumber to air dry completely. It is recommended to regularly monitor the moisture content using a moisture meter to determine when the lumber is ready for use.
HF lumber stands for "hem-fir lumber," which is a type of softwood lumber typically made from a combination of western hemlock and true firs. It is commonly used in construction for framing and general building purposes due to its strength and versatility.
Softwoods are generally less expensive than hardwoods because they grow faster and are more abundant. However, the price of softwoods can vary depending on factors such as the species, quality, and market demand. Overall, softwoods are typically more affordable compared to hardwoods.
in adults its done at L3 and L4 or L4 and L5
It is called as vertebral column. The vertebrate and non-vertebrate is one of the major classification in biology. You have 7 cervical, 12 thoracic, 5 lumber and one sacrum with coccyx to give you vertebral column.
The lumbar region of the vertebral column contains 5 vertebrae (the bones of the spine).
Actually its still spine. The spine in anatomy is the combination of the vertebral column (the bone part) and the spinal chord (the nervous tissue part). that may be all right and so but there is still another wscientific word for spine and and that is dorsal and lumber vertebrate

second lumber vertebrae
There isextension of brain in neck, thorax and abdomen in what is called as vertebral column. You have seven cervical vertebrae, twelve thoracic vertebrae and five lumber vertebrae fallowed by sacrum.In between them, you have inter-vertebral disc and various ligaments. Which keep them in position. In the hollow part of these vertebrae, there is spinal cord. It extends to the lower border of second lumber vertebrae. Down to it, there is bundle of nerves called as cauda-equina.
Yes, lumber is generally the term for wood in it's prepared form, ready to use for jobs.
They are usually divided into 3 groups: Cervical (7, Neck) Thoracic (12, Chest) Lumber (5, Abdomen) They are then given numbers starting at the top (eg. C1 (Cervical 1), C2, C3, T1, L3 ect.) Some have individual names like 'Atlas' or 'Axis' but this is uncommon.
Kiln-dried lumber is generally of higher quality than air-dried lumber because it is dried in a controlled environment, resulting in more consistent moisture content and reduced risk of warping or cracking.
You don't have to have the same number Sometimes a lower rib doesn't develop on one or both sides. Sometimes a lower thoracic vertebral bone and an upper lumber vertebral bone just below it look so much alike you can't tell which kind is which -a Musculoskeletal Diagnostic Radiologist
The lumbar vertebrae in the abdoninal region The segment, or group, of vertebrae that bear the most weight in the body is at the lumbosacral joint between lumbar vertebra number five (L5) and the sacrum.
