2/13/12 ORIENTATION TO 1ST LAB • Goals: • Anatomical Vocabulary: • Learn common anatomical terms that we will use all semester ! • Comparative Anatomy: HUMAN ANATOMY L A B # 1 : H U M A N A N AT O M Y I N P E R S P E C T I V E • Human anatomy in comparison to other mammals • Evolutionary basis for modern human features • Human variation: • Sex • Age PROCEDURE • Work in groups of 5 to 6 people • 6 Stations • 15 minutes/station; groups rotate from station to station • Review all together at the end of lab STATION 1: ANATOMICAL TERMS • What are you supposed to know? • Memorize the terms in Station 1 and be able to use the terms appropriately in complete sentences. • Where to find the information 1. Your text (Saladin Human Anatomy, 3rd ed.) 2. Other resources we have set on the table. STATION 2: COMPARISON OF CAT, MONKEY, AND HUMAN • What are you supposed to know? • Identify and name bulleted regions such as specific areas of the vertebral column, the pelvis, etc. • Context for human Anatomy: We are all mammals! • Humans share many aspects of anatomy with other mammals. • Structure/Function relationship. How do observed differences relate to adaptation/way of life? • e.g. how does anatomy relate to how the animal moves around its environment? STATION 2 • We are all mammals! • Humans share many aspects of anatomy with other mammals. • Compare skull, vertebral column, pelvis, and hands and feet; what is shared and what is unique about human anatomy?. • Go beyond description; ponder FUNCTION. How do the observed differences relate to adaptation/way of life? • e.g. locomotion—how does anatomy relate to how the animal moves around its environment? 1 2/13/12 2= ILIUM 3= ISCHIUM 4= PUBIS CAT SKELETON C O M PA R E S K U L L , V E R T E B R A L C O L U M N , H A N D S & F E E T STATION 3: COMPARISON OF CHIMP & HUMAN • What are you supposed to know? • Describe similarities and differences between humans and chimpanzees.
