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.
Normal wrist motion has a range of flexion and extension as 65-70 degrees.Radial deviation wrist motion is 20 degrees and ulnar deviation is 40 degrees. Out of total deviation, carpal bones contribute about 10 degrees of rotation while rest is contributed by forearm [about 140 degrees].The wrist motion is as a result of complex arrangements between the two carpal rows.Wristâs versatility mostly is due to the intercalated three-bone system of the proximal carpal row. During flexion and extension, each carpal row angulates to equal extent in the same direction.he wrist motion is as a result of complex arrangements between the two carpal rows.
