neuromuscular control Flashcards
what is neuromuscular control
interaction of the sensory and motor systems that enables synergists, agonists, and antagonists, as well as stabilizers and neutralizers to anticipate or respond to proprioceptive and kinesthetic information and, subsequently, to work in correct sequence to create coordinated
movements
how do we defined neuromuscular control
unconscious activation of dynamic restrain occurring in preparation for and in response to joint motion and loading for the purpose of maintaining and restoring functional joint mobility”
what is feedback control
stimulation of a corrected response within a system after sensory detection
what is feedforward control
anticipatory actions occurring before the sensory detection of a homeostasis disruption
what is stability
state of a joint remaining or promptly returning to alignment through an equalization of forces
* Complementary relationship between static and dynamic components
what is proprioception
Afferent information arising from internal peripheral areas of the body that contribute to postural control, joint stability and conscious sensations”
role of ruffini ending
Static and dynamic receptors
Low threshold, slow adapting characteristics
pacinia corpscule
role Dynamic receptors
Low threshold, quick adapting
role of GTO
Very low threshold, high dynamic sensitivity
Provide CNS with feedback concerning muscle tension
role of muscle spindle
Mainly sensitive to changes in muscle length, or rate of change in muscle length
the central axis corresponds with
spinal cord
brainstem
cerebral cortex
associated area of central axis
cerebellum
basal ganglia
which part of brain control postural equilibrium
brainstem
which part of brain Directly regulate and modulate motor activity from visual, vestibular and somatosensory information
brainstem
which part of the brain Relay station of information from spinal cord to cerebral cortex
brainstem
what type of body mvt does brainstem has a rol with
Automatic and stereotype movements of the body
role of cerebral cortex
Directing and initiating more complex and discrete voluntary movements
Responsible for choosing the muscles to be activated, force produced and direction of movement
which part of the brain program complex sequence of mvt
cerebral cortex
which part of the brain organize and prepare motor commandes
cerebral cortex
role of cerebellum
Subconscious levelàplanning and modification of motor activities through
comparison of intended movement and outcome movement
role of basal ganglia
higher order, cognitive aspect of motor control
which part of the brain that cant independly initiate motor actovity
cerebellum and basal ganglia
what can impair proprioception
joint injury, muscle damage, joint swelling
