motor skill correct answers an activity or task that requires voluntary head, body, and/or limb movement to achieve a goal movements correct answers are behavioural characteristics of the body, the head, and/or a specific limb or combination of limbs skills relate to a particular correct answers outcome movements relate to specific correct answers characteristics motor control correct answers how our neuromuscular system functions to activate and coordinate the muscles and limbs involved in the performance of a motor skill OR the ability to regulate or direct the mechanisms essential to movement 4 motor control problems correct answers - degrees of freedom - serial-order problem - perceptual-motor integration - skill acquisition degrees of freedom problem correct answers - the CNS must control many muscles and joints to perform a particular action - having many DOF provides greater flexibility - CNS needs to identify which DOFs are task relevant degrees of freedom solutions correct answers - efficiency = avoid extreme joint angles - synergy = freeze out a portion of the DOF and introduce temporary, rigid couplings between multiple DOF - relying on joint mechanics and the muscles serial-order problem correct answers sequence of elements of a movement serial-order solutions correct answers - planning includes sequential information - co-articulation or the simultaneous motions of different effectors that help to achieve a temporally extended task perceptual-motor integration problem correct answers - need to integrate sensory information to form perception and act on this information - movement normally enhances perception, but suppressive effects can occur perceptual-motor integration solutions correct answers - feedback and feedforward processes - neurons in brain encode in different coordinate systems - some neurons encode different sensory input in same coordinate system - neurons transform sensory input into motor signals
