Chapter 13: Neurologic Diseases and Conditions: Overview Flashcards
the nervous system is composed of what two divisions
central nervous system (CNS)
peripheral nervous system (PNS)
includes the brain and spinal cord
central nervous system (CNS)
structures of the brain that control the intellectual functions of thinking, willing, remembering, and deciding, and those that control personality, are located

medulla oblongata
vast network of nerves throughout the rest of the body is
peripheral nervous system
transmits impulses toward the CNS
sensory (afferent) nerves
transmit impulses away from the CNS and produce responses in muscles and glands
Motor (efferent) nerves

carotid arteries (two internal and two external) originate from the two common carotid arteries and are located in the anterior portion of the neck; the two vertebral arteries join with the cerebral arteries and posterior cerebral arteries and the two anterior and posterior communicating arteries to form
