Definition

viewed from the side, there are four slight bends of the vertebral column

Term
Abnormal Curves
Definition
  • kyphosis
  • lordosis
  • scoliosis
Term
Kyphosis
Definition
an increase in the thoracic curve of the vertebral column; may be caused by rickets and poor posture; it is common in females with advanced osteoporosis; "round-shouldered"[image]
Term
Lordosis
Definition

an increase in the lumbar curve of the bertebral column; may result from increased weight of the abdomen as in pregnancy or extreme obesity, poorposture, rickets, osteoporosis, or tuberculosis of the spine

[image]

Term
Scoliosis
Definition

most common; lateral bending of vertebral collumn, usually in thoracic region; may result from congenitally malformed vertebrae, paralysis of muscles on one side of the bertebral column, poor posture, or one shorter leg

Term
Spina Bifida
Definition
  • Spina bifida is a birth defect that involves the incomplete development of the spinal cord or its coverings. The term spina bifida comes from Latin and literally means "split" or "open" spine
  • Spina bifida occurs at the end of the first month of pregnancy when the two sides of the embryo's spine fail to join together, leaving an open area. In some cases, the spinal cord or other membranes may push through this opening in the back. The condition usually is detected before a baby is born and treated right away.
  • causes are largely unknown

Term
Intervertebral discs
Definition
  • account for about 25% of the height of the vertebral column
  • found between the bodies of adjacent vertebrae from the second cervical vertebra to the sacrum
  • avascular
  • each disc has an outer fibrous ring and an inner soft, pulpy, highly elastic substance called the nucleus pulposus
  • discs form strong joints, permit various movements of the vertebral column, and absorb vertical shock
  • under compression, they flatten and broaden
