    Heart rate, digestion, breathing, and perspiration are all controlled by which part of the peripheral nervous system
    the autonomic nervous system
    Which of the following best describes the function of nerves
    They carry sensory and motor impulses
    Which kinds of nerves are found in the peripheral nervous system
    spinal and cranial nerves
    The sympathetic nervous system and parasympathetic nervous system work together to maintain a stable
    internal state
    What are the main components of the central nervous system?
    brain and spinal cord
    Which of the following best describes the function of the brain?
    It provides the interpretative power that dictates how to behave.
    Which of the following best describes the function of the sympathetic nervous system?
    It arouses the body and expends energy
    Which of the following is the best example of the function of the peripheral nervous system?
    It connects the central nervous system to the rest of the body.
    Controlling voluntary skeletal muscles is a function of the __________ nervous system.
    somatic
    About how many neurons are in the brain?

    the peripheral nervous system
    Both the sympathetic and parasympathetic divisions can be found in the __________ nervous system.
    autonomic
    Which of the following best describes the function of the parasympathetic nervous system?
    It calms the body and conserves energy.
    What are the two divisions of the autonomic nervous system?
    sympathetic and parasympathetic nervous systems
    What are the two main components of the nervous system?

    Regulating unconscious biological functions is a function of the
    medulla
    The outermost layer of the brain, the __________, is housed in the cerebrum
    cerebral cortex
    The __________ is the innermost region of the brain.
    brainstem
    Aiding in emotional processing and arousal functions are functions of the
    thalamus
    The organ that acts as the control center for the body
    Brain; Brain processes allow us to coordinate movement, process information, and interact with the world around us
    The anterior region of the brain that is comprised of the cerebrum, thalamus, and hypothalamus
    forebrain; The forebrain is the largest and most complex region of the brain.
    The region of the brainstem that is located between the forebrain and hindbrain
    midbrain; Before our brain can fully integrate our audio and visual sensory information, it must first be projected through the midbrain.
    The region of the brain that is located underneath the forebrain and the midbrain.
    hindbrain; The hindbrain contains all of the structures positioned lowest in the brain
    The largest part of the forebrain that is responsible for the integration of sensory and neural functions
    cerebrum; The cerebrum is divided into two hemispheres and houses the cerebral cortex
    The brain structure that serves as the main input center for most sensory information.
    thalamus; All incoming sensory information is sorted through the thalamus and sent to the higher brain centers for further processing
    The innermost region of the brain that includes structures of the midbrain and hindbrain.
    brainstem; The brainstem plays a very important role in the conduction of neural impulses up to the brain, as it is where the reticular formation is found.
    Brain structure located in the hindbrain that is largely responsible for unconscious biological functions
    medulla; Biological functions regulated by the medulla include breathing, heart and blood vessel activity, swallowing, vomiting, and sneezing.
    Structure located in the hindbrain that connects the brainstem to the cerebellum.
    pons; The pons is adequately named from the Latin term for “bridge” because it connects the brainstem to the cerebellum.
    Brain structure located at the back portion of the brainstem
    cerebellum; Hand-eye coordination is one example of the function of the cerebellum
    Which of the following make up the three regions of the brain?
    forebrain, midbrain, and hindbrain
