biod 151 module 1 Study online at https://quizlet.com/_dykfg7 1. what is the study of the function of the human body physiology 2. ___ is an example of the organ level of organization in the human body liver 3. what is the synthesis of more complex structures anabolism 4. list the four basic types of tissues epithelium, mus- cle, connective, nervous 5. list the three layers of the skin in order from superficial to deep. 1. epidermis (outer layer) 2. dermis (middle layer) 3. hypoder- mis (inner/subcu- taneous tissue lay- er) 6. testosterone contributes to muscle strength and bone mass. based upon your learning of metabolism, would it be considered an anabolic or catabolic hormone? explain why? anabolic because it is the building of new tissues from smaller cells 7. what anatomical orientation term is used to indicate "toward the back of the body"? dorsal/posterior 8. what anatomical orientation term is used to indicate "toward the upper part of a structure"? superior/cranial 9. what anatomical orientation term is used to indicate "away from the head end"? inferior/caudal 10. what anatomical orientation term is used to indicate "further from the origin of the body part"? distal 11. you are looking at a diagram of a patient standing in anatomical position. on the sheet of paper containing left 1 / 5

The thoracic cavity is superior to the di- aphragm. 16. list two organs contained in the pelvic cavity bladder, reproduc- tive organs, rec- tum 17. true or false: the ventral body cavity contains the cranial cavity, the thoracic cavity, and the abdominal cavity. if your answer is false, rephrase the statement to make it a true statement false. the ven- tral cavity contains the thoracic cavity and the abdominal cavity 18. the body is divided into anterior and posterior sec- tions by what type of plane frontal/coronal 19. a section that is diagonal between horizontal and ver- tical planes is called what oblique 20. a cell beginning to shrink is in what solution hypertonic 2 / 5
