Mississippi's whole body donors: Analysis of donor pool demographics and their rationale for donation.

Background: Whole body donation (WBD) is fundamental to anatomical education and research because human dissection provides an educational tool for training healthcare professionals. Investigation into the demographics and rationale of whole body donors can provide insight on who donates their bodies to science. Literature reports a typical donor who is a 60 to 70-year-old, white, married, educated man with the reason for donating to be altruism.

Improving Academic Performance Using an Innovative Cranial-Nerve Table.

To facilitate the review and retention of the complicated contents of the Head Block in the Dental Gross Anatomy course, an innovative cranial-nerve table was introduced to first-year dental students using an interactive self-retrieval format. Our analysis of exam data shows the efficacy of this learning tool.

Visualization of stereoscopic anatomic models of the paranasal sinuses and cervical vertebrae from the surgical and procedural perspective.

Recent improvements in three-dimensional (3D) virtual modeling software allows anatomists to generate high-resolution, visually appealing, colored, anatomical 3D models from computed tomography (CT) images. In this study, high-resolution CT images of a cadaver were used to develop clinically relevant anatomic models including facial skull, nasal cavity, septum, turbinates, paranasal sinuses, optic nerve, pituitary gland, carotid artery, cervical vertebrae, atlanto-axial joint, cervical spinal cord, cervical nerve root, and vertebral artery that can be used to teach clinical trainees (students, residents, and fellows) approaches for trans-sphenoidal pituitary surgery and cervical spine injection procedure. Volume, surface rendering and a new rendering technique, semi-auto-combined, were applied in the study.

The hLAMP-1-positive particulate matrix involved in cardiac mesenchyme formation in the chick does not include BMP-2.

Early heart development involves the transformation of endocardial cells in the atrioventricular canal and outflow tract regions into mesenchymal cells, a process called endocardial mesenchymal transformation (EMT). This process is initiated by factors, termed the particulate matrix, that are secreted by the myocardium. The particulate matrix causes a subset of endocardial cells to hypertrophy, lose their cell-cell contacts, form migratory processes, transform into mesenchymal cells, and migrate into the underlying endocardial cushions.
