Document Summary
Passive force is due to stretching of the elastic molecule titin (connectin). As a muscle get shorter the force began to go down . There is no passive or active force at that time because the muscle is not producing anything. There is a linear relationship between the input and the output of the force during contraction. The cns controls actuators that are not linear with feedback control. A negative feedback control loop automatically minimises error between desired and actual output, . Receptor that control feedback for respiration is baroreceptors. She can control her movement because her eyes are closed. Mechanoreceptors respond to pressure that depolarize initial region of the axon. To measure nerve velocity in a arm, the one close to the muscle give s short response. Diabetes reduce the conduction velocity because axons are compressed. Population code: the more you pressed the more you modify the skin surface, can generated 500,000 action potential per second. (a) population code.
