motor behavior quiz #5 Flashcards
a main difference between skills and reflexes is that skills are innate and involuntary while reflexes are learned and voluntary
false
the brain and spinal cord make up the central nervous system
true
the compensation period may occur during adolescence, adult, and/or older adulthood
true
efferent pathways send/transmit electrical signals from the brain to the muscular system.
true
the brain stem is the area of the brain that involves basic, vital functions such as breathing
true
motor control involves the question ‘‘how does the brain control the movement of the body?’’
true
to watch and respond to the movement of an offensive player in field hockey, a defender would engage in afference followed by efference.
true
integration of sensory information takes place in the peripheral nervous system
false
both autonomic and somatic components of the nervous system have connections to the spinal cord
true
sensory neurons are afferent neurons
true
most neurons are motor neurons
false (interneurons)
chemical transmission between 2 neurons occurs at a synapse.
true
afferent pathways send/transmit electrical signals (sensory information) from the muscular system to the brain.
true
the presynaptic neuron is the transmitter and its impulse travels toward the synapse
true
which type of axon has the slowest conduction speed?
large axon diameter with low amount of myelin
which of the following proposes that warm, caring, and supportive relationships are important for healthy development?
attachment theory
which of the following proposes that development involves multiple, continuous influences such as genetic, neural/cognitive, behavioral, and social/environmental?
dynamic systems theory
which of the following best relates to the following statement, ‘‘the study of changes in motor behavior across the lifespan and the processes that underlie these changes?
motor development
which of the following are levels of the mountain of motor development?
skillful, compensation, pre-adapted, context-specific, fundamental motor patterns, reflexive
which of the following would best include the topic of locomotor skills?
fundamental motor patterns
which of the following are characteristics of action potentials?
-obeys all or none law
