However a lot of time has past since then and we now have lots of furry creatures that are collectively called mammals. How did they get their? Where did they come from? These are the kinds of questions that led me to my subject of choice. I will endeavor to provide examples‚ using specific transitional fossils‚ to show that

OB PROJECT (WEEK 4) Definition: Spinal Bifida- congenital neural tube defect in which the vertebral spaces fail to close‚ allowing a herniation of the spinal contents into a sac. There are three types of spinal bifida: spinal bifida occulta‚ meningocele‚ and myelomeningocele. Cause: In spinal bifida‚ the vertebral spaces do not close‚ which allows herniation of the spinal contents into a sac. Risk factors include: • Genetic problems • Infection • Children born into lower socioeconomic families

sagittal cleft that separates the spinal cord along with the posterior vertebral components at varying levels such as‚ Conus Medullaris and Filum Terminale. Diastematomyelia is caused by an Osseous‚ cartilaginous‚ or fibrous septum. It results in either complete or incomplete sagittal division of the spinal cord into two hemicords. This condition could either be isolated or associated with other segmental abnormalities of vertebral bodies. It is classified into two types‚ Type

vital information about any history of falls/trauma‚ history of spinal fractures and comorbidities. It is important to review the results of any radiography tests (CT scan results‚ bone densitometry or MRI) as these may reveal the need to have a vertebral augmentation. As we proceed with the evaluation‚ it would be necessary also to review the current medications of our patients because procedures like kyphoplasty and vertebroplasty patients should be taken off all anticoagulants (Burton & Hamid‚

closed neural tube defects‚ the spinal cord has malformations of fat‚ bone‚ and meninges.1 Spina bifida meningocele occurs when spinal fluid and meninges protrude through an abnormal vertebral opening.1 This type of spina bifida does not have any neural contents in the vertebral opening.1 Depending on the patient‚ the vertebral opening may or may not be covered by skin.1 A person with meningocele may have very few symptoms‚ or may experience several severe symptoms.1 The final type is myelomeningocele;
