Spina Bifida Spina Bifida is a rare birth defect that causes a malfunction in a baby’s spine when it develops. The spinal column is supposed to be closed all the way around‚ but for some children it never fully closes. This allows spinal nerves‚ cords‚ and sacs of fluid that would otherwise be enclosed be exposed. It can lead to serious damage like paralyzation. 8 children are born with this in the United States every day. “SB mostly occurs during first trimester of pregnancy.” Although nobody is

Framework of the Skull The bony framework of the head‚ called the skull‚ is subdivided into two parts: the cranium and the facial portion. Refer to Figures 3-5 through 3-8‚ which show different views of the skull‚ as you study the following descriptions. Color-coding of the bones will aid in identification as the skull is seen from different positions. Cranium This rounded chamber that encloses the brain is composed of eight distinct cranial bones. * The frontal bone forms the forehead‚ the anterior

Compare the bone markings of the vertebrae and distinguish the differences between the cervical‚ thoracic‚ and lumbar vertebrae. The vertebrae are the irregular bones that create the spinal column. These irregular bones are divided into four sections which are the cervical‚ thoracic‚ lumbar‚ and sacral or pelvic spine sections‚ which are also referred to as curvatures. There are seven vertebrae that make up the cervical spine (neck); twelve vertebrae that make up the thoracic spine (chest); five

Imbalance The spine is composed of bones called the vertebrae. The vertebrae purpose is to work with fibers to sort the spinal cord. The vertebrae are classified by main regions called the cervical‚ thoracic‚ lumbar‚ sacrum and coccyx. When there is an unusual disease affecting the spine by making an arch it is called scoliosis. Scoliosis is mainly now for its shaped S or C in the spinal column. Its twist and rotation‚have cause deformation in different parts of the section of the spine. Scoliosis can be

Cranial cavity‚ spinal cavity‚ thoracic cavity‚ abdominal cavity‚ and pelvic cavity are the five body cavities. The cranial cavity contains the brain‚ cranial nerves‚ and other structures. Spinal cavity is within the bones of the spinal column. It contains the spinal cord and spinal nerves. Thoracic cavity contains the lungs.

Gustavo Carro BIO-105 Human vertebral column In human anatomy‚ the vertebral column is a column usually consisting of 24 articulating vertebrae and 9 fused vertebrae in the sacrum and the coccyx. It is situated in the dorsal aspect of the torso‚ separated by intervertebral discs. It houses and protects the spinal cord in its spinal canal. There are normally thirty-three (33) vertebrae in humans‚ including the five that are fused to form the sacrum (the others are separated by intervertebral
