My name is Sarah, I am an Intern here at HDAC. I am currently a senior at the University of Maryland studying biological anthropology. Within biological anthropology I am most interested in studying the molecular and genetic applications of Anthropology. I am excited to learn about developmental embryology this summer here at HDAC.
Today Rebecca and I decided on the topic of our Intern project. We wanted to incorporate the neural tube development and pathology with comparative anatomy. To do this we have been looking into the development of the central nervous system (CNS). The two main books we have been looking at are Langman’s Medical Embryology (Eighth Edition) by T.W. Sadler, Ph.D. and Basic Concepts in Embryology: A Student Survival Guide by Lauren J. Sweeney. It was easy to find issues related to CNS development. If the neural tube does not close properly during the first four weeks of gestation entire sections of the brain and/or spinal cord can be exposed. Spina bifida is a neural tube defect (NTD) that occurs when the neuropore does not fuse. Eventually we will also look further into comparative anatomy regarding brain development.
