Anatomical Terminology and Muscle Identification

Dr. Morton introduces the directional terms 'anterior' and 'posterior', explaining their definitions and usage in anatomy. Anterior refers to the front, while posterior refers to the back. The video provides practical examples, such as the position of the hand and sternum, and discusses muscle identification using these terms. It also covers spinal cord anatomy, highlighting the dorsal and ventral horns, and includes a neck dissection to identify muscles. Finally, a CT scan analysis demonstrates identifying posterior regions, summarizing the key concepts of anterior and posterior in anatomy.
