Of, relating t,o or constituting the loins or the vertebrae between the thoracic vertebrae and the region of the sacrum. The sacrum is the triangular bone made up of five fused vertebrae that forms the posterior section of the pelvis. The thorax is the part of the human body between the neck and the diaphragm, partially encased by the ribs and containing the heart and lungs; that is, the chest.
The lumbar section of the spine consists of five vertebrae, referred to as L1 through L5 and is the lower part of the spine between the thoracic region and the sacrum. There are five lumbar nerves correspond to the five lumbar vertebrae.
region of the back between the thorax and the pelvis Motor Unit the motor neuron together with the muscle fibres that it innervates. It varies in size greatly for extraocular muscles. It is 510 muscle fibres per motor nerve while for gastrocnemius it is 1600 1900 muscle fibres per motor nerve.
The lower part of the spine between the thoracic region and the sacrum. The lumbar spine consists of five vertebrae. The five moveable spinal segments of the lower back and largestof the spinal segments.
Referring to the 5 lumbar vertebrae which are situated below the thoracic vertebrae and above the sacral vertebrae in the spinal column. The 5 lumbar vertebrae are represented by the symbols L1 through L5. There are correspondingly 5 lumbar nerves.
The lumbar refers to the lower portion of the back, between the dorsal (thoracic) and sacral portions of the spine. The 4th lumbar center is a key coordinating nerve center providing nerve energy to the pelvic organs and lower locomotories (legs).
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.
