Quickly memorize the terms, phrases and much more. The concavity index of the sheep was greater than humans especially at the caudal lumbar vertebrae and its values at L1, L2 and L5 were comparable with those of humans. There are also seven cervical (neck) vertebrae, 13 thoracic (ribcage) vertebrae, six lumbar … Therefore, discovering how many vertebrae we have also reveals their name and location within the body. It usually takes between 2 to 2.5 minutes per sheep, although it takes longer to do the rams and wethers (the castrated male sheep) since they have a larger frame. It is truly back breaking work. They are also shorter in height, with long, flattened transverse processes that project laterally. A modern shearer gets through 40 sheep per hour in an 8 hour day. The six lumbar vertebrae, L1 to L6, make up the spine between the thoracic vertebrae and the pelvis. Lumbar Vertebrae.
