Skull fontanelles

The video tutorial by Dr. Morton, The Noted Anatomist, explores the anatomy and functions of fontanelles in the fetal skull. It covers the structure of the fetal skull, the role of fontanelles in childbirth and brain growth, and conditions like hydrocephalus and cleidocranial dysplasia. Fontanelles, also known as soft spots, are crucial for skull flexibility during childbirth and accommodating rapid brain growth. The tutorial also highlights the cultural practice of head binding and the condition CCD, which affects fontanelle fusion.
