BIOLOGY 2325 HUMAN ANATOMY 75 Points Possible FIRST MIDTERM EXAMINATION SPRING SEMESTER 2011 Name Last First (Please print clearly) DIRECTIONS: Read each question carefully before answering. 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 9 questions and 6 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. 1. (12 points) Fill in the table with the proper tissues. If a structure consists of more than one tissue, list all tissues in that structure. Structure Arytenoid cartilage Tissue Myocardium Tunica adventitia of bladder Muscularis mucosae Lining of eccrine sweat gland Tunica mucosa of the ureter Tunica media of an artery Synovial membrane of a bursa Epimysium Meniscus Stratum reticulare of dermis Tunica mucosa of oral cavity

2 Name 2. (9 points) In the illustration of the integument below, clearly color-code each anatomical feature listed in Column 1 that has a box to the left of it. (Color the box to the left of the structure the same color that you color the structure in the illustration. When coloring the structure in the illustration, you must color it in its entirety. Also, make certain that the coloring is clear, distinct, and unambiguous. If coloring does not clearly demonstrate the entire labeled structure it will be marked wrong.) In Column 2, list the specific function of each layer, structure, or gland (list the function of the gland, not what it secretes) that is followed by a dotted line. Column 1 - Structure Column 2 - Function Epidermis Stratum corneum Stratum granulosum Stratum spinosum Stratum basale Hypodermis Eccrine sweat gland Apocrine sweat gland Sebaceous gland Hair follicle Arrector pili muscle Dermal papilla Dermal stratum papillare Dermal stratum reticulare 2

3 Name 3. (9 points) On the illustration of a section through the knee joint below clearly label, with distinct colors, all the structures listed in the column below. In the box next to each structure indicate the color used to label the structure on the illustration. You must color every structure in its entirety in all parts of the illustration. Partial coloring of a structure will be marked incorrect. Compact bone distribution Subchondral bone region Articular cartilage Periosteum Spongy bone distribution Medullary cavity Meniscus Fibrous membrane Synovial membrane 4. (3 points) Describe three structural features shared in common by a bursa, a synovial sheath, and a synovial capsule

4 5. (6 points) Fill in the blanks or circle the correct answer in the sentences below. Name and muscle tissue are both involuntary muscle, whereas muscle tissue is voluntary muscle. The perimysium is a thin layer of tissue that wraps around many muscle cells to form a unit within muscle called a. Slow oxidative (Type I or tonic) muscle fibers fatigue faster/slower (circle the best answer) than fast glycolytic (Type IIB or twitch) muscle fibers. 6. (10 points) Trace a molecule of urea from blood in the aorta through the kidney and into the toilet. Your trace must list all circulatory structures, urinary structures, and any tissue barriers traversed by this urea molecule. Urea molecule in blood of aorta Toilet 4

5 Name 7. (14 points) In the columns below trace a red blood cell from the capillaries of the left hand to the capillaries of the right foot. Your trace must list all heart chambers and valves, and the circulatory vessels traversed by the red blood cell in the column below. Capillaries of the left hand Capillaries of the right foot 8. (4 points) An osteon is the principal subunit of compact bone. For each key structure of an osteon listed below, describe what would be found in that structure in living bone, in other words, what occupies the structure listed below. Lacuna - Canaliculi - Central canal - Lamella - 5

6 9. (8 points) Label each numbered item in the illustrations below. Name 1. #1 2. (Circled structure) #2 7. #3 8. #4 #5 #6 #7 #8 6
