Then separate the last page of the exam and answer all the short answer/essay questions. When finished, fold the last pagein half lengthwise, write the first 3 letters of your last name in the blanks provided, and insert your computer form. Finally, shove the folded last page between the pages of this stapled question section, write your name on the exam, and turn it in.1.

What is the name of the brain part indicated by letter “E”?a. cerebrum/frontal lobeb. cerebellum/occipital lobec. cerebrum/temporal lobed. diencephalon/hypothalamuse. brain stem5. The most superficial of the meninges surrounding the brain is the:a. dura materb. arachnoid layerc. mediastinumd. pia matere. cephalomater6. The Organ of Corti which responds to different frequencies of sound can be found in:a. the cochlea of the inner earb. the semicircular canals of the inner earc. the retina of the eyed. the taste buds of the tonguee. the receptor area of the site of olfactionBIOS 160 Exam II pg 1 A B C D EUse the eye diagram at the right to answer the following questions.7. Which structure is known as the retina?8. Which structure is known as the choroid layer?9. Which structure is a transparent and clear part of thesclera?10. Which structure senses light and produces a nerveimpulse?11. Which space is filled with aqueous humor?12. Which structure changes shape when muscles pullor relax?13. Which arrow points to the pupil?14. Which layer contains the cells called rods andcones?----------------------------------------------------------------TRUE/FALSE Answer "a" if true and "b" if false.15. The word "accommodation" in reference to the human eye refers to howwell the lens fits within the pupillary gap.16. Rod cells in the eye are more sensitive to weak light than cone cells.17. Both hearing and the sense of equilibrium are achieved through thebending of hairs on special cells that can initiate an action potential.18. The lens of the eye is thinnest when focusing on objects that are far away(see diagram to the right).19. The function of the incus (anvil), malleus (hammer), and stapes (stirrup)bones are to:a. Support and hold open the pharyngotympanic tubeb. Amplify and transmit sound vibrations between the tympanic membrane and oval windowc. Support the base of the tongued. Provide anchoring points for the hypothalamus of the diencephalone. Protect the delicate olfactory receptorsBIOS 160 Exam II pg 220. In which structure (in the diagram to the right) aresounds converted into nervous impulses?21. Which structure is technically called the tympanum?22. Which structure helps to equalize the pressurebetween the inner ear and the environment?23. Which arrow points to the stapes bone?--------------------------------------------------------------------------------------------------------------------------------------------Match the hormone on the left with the organ or structure that produces it on the right. If the correct answer is morethan one letter, like "abc", fill in "a" AND "b" AND "c" on your answer sheet for that question.24.

The hormone responsible for regulating wakefulness and sleepiness.------------------------------------------------------------------------------------------------------------------------------------------32. In the steroid hormone mechanism of action, the hormone binds to a receptor and:a. acts to initiate transcriptionb. stimulates the production of second messenger like cAMPc. causes change only in the cytoplasm of the target celld. moves through the blood stream to other cellse. causes glucose breakdown within the cell33. The hypothalamus signals the release of hormones in the anterior pituitary by sending electrical signals through a “wire”. This type of stimulus is known as:a. neural stimulusb. hormonal stimulusc. humoral stimulusd. bipolar diphasic stimuluse. intentional stimulus--------------------------------------------------------------------------------------------------------------------------------------------BIOS 160 Exam II pg 3True/False Questions. Mark "a" if true and "b" if false.34. One function of the thyroid gland is to regulate the rate of cellular respiration in most of the body's cells.35. Glucagon and aldosterone have exactly opposite effects in regulating blood glucose levels.36. The risk of seeing a huge destruction of red blood cells in a newborn baby is greatest if the mother is Rh positive and the father is Rh
