After studying this chapter, you will be able to:
Though you may approach a course in anatomy and physiology strictly as a requirement for your field of study, the knowledge you gain in this course will serve you well in many aspects of your life. An understanding of anatomy and physiology is not only fundamental to any career in the health professions, but it can also benefit your own health. Familiarity with the human body can help you make healthful choices and prompt you to take appropriate action when signs of illness arise. Your knowledge in this field will help you understand news about nutrition, medications, medical devices, and procedures and help you understand genetic or infectious diseases. At some point, everyone will have a problem with some aspect of his or her body and your knowledge can help you to be a better parent, spouse, partner, friend, colleague, or caregiver.
This chapter begins with an overview of anatomy and physiology and a preview of the body regions and functions. It then covers the characteristics of life and how the body works to maintain stable conditions. It introduces a set of standard terms for body structures and for planes and positions in the body that will serve as a foundation for more comprehensive information covered later in the text. It ends with examples of medical imaging used to see inside the living body.
Question: Branches of which cerebral artery vascularize the primary auditory cortex, Wernicke's area, and the angular gyrus?
Choices:
Thalamogeniculate.
Anterior Choroidal.
Middle Cerebral.
Posterior Cerebral.
Question: Which of the following is the lowest level at which "BINAURAL" input to the same neuron occurs?
Choices:
Hair Cells.
Spiral Ganglion Cells.
Cochlear Nuclei.
Superior Olivary Nuclei.
Inferior Colliculus.
Question: This artery supplies the Visual Cortex. Which one is it?
Choices:
Anterior Cerebral Artery.
Middle Cerebral Artery.
Posterior Cerebral Artery.
Question: The receptors in the Organ of Corti are hair cells. How are they stimulated?
Choices:
By air-borne waves.
Displacement of the vestibular membrane.
Displacement of the basilar membrane.
Displacement of the tectorial membrane.
Question: Unilateral Cerebral strokes can cause deficits in motor control, somatic sensation and vision. However, they do not cause deficits in hearing. The explanation for this is:
Choices:
Auditory information does not reach the cortex
Auditory information only goes to one hemisphere.
Auditory information goes to both hemispheres
Question: Cranial nerves VII and VIII pass through the:
Choices:
Stylomastoid foramen.
Jugular foramen.
Internal auditory meatus.
Oval foramen.
Question: Tumors originating from the Schwann cells of CN VIII (acoustic neuromas) are not uncommon. As the tumor grows, it not only compresses VIII but also encroaches upon adjacent cranial nerves. What cranial nerve close to VIII is likely to be involved? Choose one.
Choices:
IX and X.
VII.
V.
VI.
Question: Where is the dorsal root ganglion of the auditory portion of VIII ?
Choices:
In the medulla.
In the bony spiral lamina.
In the internal auditory meatus.
In the facial canal.
Question: Where are the cell bodies for the auditory part of this nerve?
Choices:
Otic ganglion.
Nodose ganglion.
Vestibular nuclei.
Spiral ganglion.
Cochlear Nuclei.
