Chapter 16: Sensory, Motor, and Integrative Systems – Flashcards

The awareness of differences in the external or internal environment is defined as: perception transduction sensation integration conduction

Which of the following would not be considered to be a sensory modality? pain vision equilibrium thought vibration

A generator potential produces action potentials and a receptor potential causes release of neurotransmitters. True/False

Which of the following does NOT consist primarily of rapidly adapting sensory receptors? body position touch pressure smell

Which of the following somatic sensations has an encapsulated nerve ending as its sensory receptor? tickle pain heat or cold pressure itch

The best example of referred pain is: shoulder pain while throwing a baseball pain still present several minutes after stubbing your toe pain felt into the left arm during a heart attack pain down your leg from a pinched nerve in your back

The body parts represented by the largest area on the somatosensory map are the: trunk fingers shoulders thighs legs

The basal ganglia provide direct input to the lower motor neurons (final common pathway). True/False

The vocal cords, lips, and face combined would occupy a larger area in the primary motor area of the cerebral cortex than the wrist, elbow, and shoulder combined. True/False

Which of the following is not a function of the cerebellum? monitors actual movement provides movement corrections monitors intentions for movement initiates movement receives input from the vestibular apparatus in the inner ear

Which stimulus does not stimulate the reticular activating system (RAS)? an alarm clock pain smoke bright light movement of the limbs

Sleep walking occurs in which stage of non-rapid eye movement (NREM) sleep? stage 1 stage 2 stage 3 stage 4

Memory is best defined as: the reinforcement that results from frequent retrieval of a piece of information the capability for change while learning the way in which information is stored and retrieved the ability to attain new information or skills

The term used for an increased memory response to an event is: synesthesia long-term potentiation memory consolidation plasticity bradykinesia

Sensation differs from perception in that perception involves activity of the cerebral cortex. True/False

Different somatic sensations are detected by different types of receptors True/False

Special senses like taste, hearing and vision require receptors that are separate from the first order neuron. True/False

The general senses are detected by receptors on the dendritic nerve endings of first-order-sensory neurons. True/False

Adaptation of sensory receptors involves decreasing the receptor potential as a stimulus decreases in intensity. True/False

People would benefit from losing the ability to perceive pain. True/False

Pain sensation is detected by slowly adapting receptors. True/False

Calling a receptor a mechanoreceptor is classifying that receptor by 1. type of stimulus detected 2. location 3. structure 1 only 2 only 3 only 1 and 2 are correct. 1, 2 and 3 are correct.

Which network of neurons is responsible for arousal and maintenance of consciousness? limbic system reticular activating system tectospinal circuit reticular activating system and tectospinal circuit are both correct limbic system, reticular activating system and tectospinal circuit are all correct

Changes in neurons that allow for learning and for changes in behavior are known as: plasticity long-term potentiation NREM plasticity and long-term potentiation are both correct plasticity, long-term potentiation and NREM are all correct

Damage to upper motor neurons results in flaccid paralysis and a loss of reflexes on the same side of the body as the injury. True/False
