For Neuromusculoskeletal Systems concepts and terminology, see the chapter by Winters on Terminology and Foundations of Movement Science [as Word doc (576K) or htm (371K)], plus 

Muscle Actions (Table H)

Biomechanics & Movement Science (Table I)



For Terminology & Foundations of Movement Science, you are to scan the chapter so as to understand the following words that are in bold within the text:

Section 2 on Systems:  system, input, output, state variables, SISO system, MIMO system, unidirectional, action potential, twitch response, impulse response, tetanus, step response, bidirectional, isokinetic, isotonic, isometric, contractile element, series element, parallel element, constitutive relations, nonlinear, operating range, energy dissipating elements, muscle power

Section 3 on Musculoskeletal Mechanics: eccentric, concentric, stretch-shortening, origin, insertion, actuator, moment arm, multiarticular, synergist, antagonist, kinematics, rigid body, serial chain, four bar linkage, axis of rotation, planar, spatial, generalized joint, constrained, restrained, velocity, acceleration, jerk, kinematic redundancy, forward kinematics, inverse kinematics, static equilibrium, quasi-static, statically determinant, statically indeterminant, stable equilibrium, dynamics, mass moment of inertia, anthropometric tables, equations of motion, inverse dynamics, forward dynamics.

Section 4 on Neuromotor Terminology & Function: sensory neurons, motor neurons, interneurons, muscle cells, motor pool, motor unit, motor end-plate (neuromuscular junction), slow-twitch (type 1) fibers, fast-fatigable (type 2b), fast-fatigue-resistant (type 2a), orderly recruitment, size principle, firing rate, pennation angle, aponeurosis.

Section 6 on Neural Control:  Negative feedback, feedback control, unstable, parameters, signals, adaptive control system, synaptic weights, impedance control.
