SOPHIA Human Biology BIO-210 Introduction to Anatomy and Physiology Unit 3 – Milestone 3 1. Which developmental disorder of the brain hinders thinking, language and social skills? Autism 2. The cerebellum is the part of the brain that controls voluntary movements, while the medulla oblongata helps regulate activities that we do not control, including breathing and heartbeat. 3. Which structure of the ear monitors movement and equilibrium via its semicircular canals and two fluid-filled sacs? Vestibular apparatus 4. Dan is dehydrated. Which type of receptor alerts his brain of this? Osmoreceptor 5. How are signals transmitted using neurotransmitters? From the presynaptic cell to the postsynaptic cell across a synapse. 6. Which of these is TRUE of a neuron at resting potential? The neuron has more potassium ions inside than outside. 7. Which part of the cerebral cortex interprets the meaning of sensations? Sensory areas 8. Which ear disorder occurs when movement over-stimulates the hair cells found in the inner ear? Motion sickness 9. In the future, spinal cord injuries and diseases like Parkinson’s may be treated with stem cells. 10. Which nerves are mostly involved in pupil dilation and other “fight-or-flight” responses? Sympathetic 11. What is the purpose of the myelin sheath? To transport action potential faster. 12. Which part of the brain receives nerve impulses from the optic nerve? Visual cortex 13. Which eye disorder has the following characteristics: Eyeball is wider than it is tall; Images focus in front of the retina rather than on it. Myopia 14. Which of the following statements is true? The axon conducts signals away from the cell body. 15. Choose the correct order in which we experience taste/gustation. 1) Pores of taste buds receive stimuli, 2) Taste buds are stimulated, 3) Taste receptors signal sensory neurons, 4) Sensory neurons send signal to the brain for interpretation 16. What is the cerebral spinal fluid’s primary role? Washing the brain of metabolic waste. 17. Which area of the brain receives information collected from mechanoreceptors? Somatosensory cortex...
