In the Igbo culture, masks are used in almost all of the ceremonies and are essential to the understanding of the holiday. Also, both cultures have holidays that celebrate ancestors and family. Such as the american Fathers day, and the Igbo celebration of ancestors.
Bending forward or rounding your lower back is called flexion. Flexion in the lumbar spine is primarily limited by compression of the intervertebral disks and tension in the ligaments that run along the back of the spine. The normal range of movement of lumbar flexion is 40 to 50 degrees.he range of motion, or how far your spine can move, is limited by the disks between the vertebrae, the ligaments that tie the vertebrae together and the orientation of the facet joints on the back part of the vertebrae.
United Kingdom. Range of motion or ROM is a medical/anatomical definition not a mathematical one. The range of 180-360 degrees is not factored in, presumably because the lower leg cannot move in an entire circle! To measure degrees of flexion using the goniometer, the zero is on the ankle and the 180 on the hip.Thus full extension is 0 degrees.As the foot moves towards to hip, so the numbers go up-the right angle at the knee being (hardly surprisingly) 90 degrees, and so on.ange of motion or ROM is a medical/anatomical definition not a mathematical one. The range of 180-360 degrees is not factored in, presumably because the lower leg cannot move in an entire circle!
