Understanding the questions is a part of the examination. Answer all questions in the spaces provided on the examination. Print your name in the space provided on the first page and at the top of each subsequent page. This examination consists of questions and 9 pages. It is your responsibility to see that the examination is complete. DO NOT WRITE IN RED. Please write in a legible fashion. If we cannot read your answer it will be marked wrong.. (0 points) Trace a marked molecule of urea from the heart, through the kidney, to the point where it emerges from the body as a component of urine. List all the circulatory structures, urinary structures, and tissue diffusion barriers through which the molecule passes on its course through the body. Your trace should be in the form of a columnar list in the columns below. Heart Toilet

2 . (0 points) For each structure in Column I write the tissue from which it is made in Column II. Column I Column II Tunica mucosa of the principal bronchus Tunica intima of aorta Epiphyseal growth plate Dermis Tunica mucosa of the bladder Tendon Endomysium Periosteum Epiglottal cartilage Lining of sweat gland. (0 points) Define the term mesentery and clearly describe its relationship to the anatomy of the peritoneal coelom. In the columns below list the peritoneal organs that have a mesentery and those that are retroperitoneal. Description of the term mesentery Organs with a mesentery Retroperitoneal organs

3 . (0 points) In the spaces below write the correct vessel name for the corresponding labels in the illustrations

4 5. (0 points) Answer the questions that follow. Name The ischioanal fossa is found between which two layers of the lateral body wall? Name the body wall nerve and vessels that pass through the ischioanal fossa. How do these vessels and nerve relate to the sacrospinous and sacrotuberous ligaments? The deep perineal pouch corresponds to which layer of the body wall? Name four structure found in this pouch in the male: Name four structures found in this pouch in the female: List the muscles that form the erector spinae musculature. The pectoralis minor muscle shares a common attachment with two other muscles. Name the muscles and their common point of attachment on the skeleton.

5 6. (0 points) Fill in the table below. Name Muscle Origin Insertion Rhomboideus minor Teres minor Infraspinatus Coracobrachialis Subscapularis 7. (0 points) On the illustration of the cross section through the thigh, label the numbered muscles in the column below and color code the three muscle compartments of the thigh. Anterior compartment Posterior compartment Color Medial compartment

6 8. (8 points) Fill in the table below. In the action column you need only list one action the muscle produces, but you must state at what joint the action produces movement to receive credit. Muscle Origin Insertion Sartorius Vastus lateralis Semitendinosus Obturator internus Gluteus medius Adductor brevis Tensor fasciae latae Pectineus Piriformis 6

7 9. (8 points) For each numbered muscle in the diagram below, write its name on the first line and one joint movement that it produces when it contracts on the second line (the action must be accompanied by the name of the joint it moves).. Name What nerve innervates all the muscles illustrated in these drawings?

8 0. (8 points) The branchial (pharyngeal) arches play a significant role in the development of head musculature. The first two arches are major contributors to the facial anatomy. Fill in the table below for the first two branchial arches. List six muscles from the st arch List six muscles from the nd arch Name and number for nerve of st arch Name and number for nerve of nd arch. ( points) Label the papillae in the illustration below. For each papilla describe its functional significance and its location on the dorsal surface of the tongue. Name Location 8

9 . (0 points) Label the muscles indicated in the illustration and on the line below the number write the name and number of the cranial nerve that innervates the labeled muscle. Also, answer the questions that follow... X.. What is the function of muscle #? What specific nerve innervates the skin in the region marked by the X?. (8 points) Answer the questions pertaining to the illustration of a cochlear section below. D C A B What is the name of structure A? What is the name and number of the cranial nerve that the neurons indicated by B travel through to the brain? Name and Number What is the name of structure C? What type of fluid surrounds structure C? When a pressure wave is introduced into the cochlea, what structures vibrate as a result of the wave? What structure fills the opening into structure D? Within what bone of the skull is this anatomy located? 9
