consists of a single motor neuron and all the muscle fibres that it innervates

is defined as all of the muscles that act about the same joint.

consists of a whole muscle and all of the motor neurons that innervate it.

can produce a graded contraction as the action potential travelling down the nerve axon excites progressively more muscle fibres.

Greatest when the H-band is at its widest

Greatest when the myosin filaments are next to the Z-lines

Directly related to the size of the sarcomere

Directly related to myofilament overlap

Indirectly related to the length of the myosin tails

First use rate coding and recruitment of small motor units, then of intermdiate sized motor units, and finally of large motor units

First use the mechanism of rate coding and when all motor units are activated, they then use the recruitment 

First recruit small motor units, then recruit intermdiate sized motor units, and finally use recruitment and rate coding of large motor units

First use the mechanism of recruitment and when all motor units are activated, they then use the rate coding mechanism

First use rate coding of small motor units, then rate coding of intermdiate sized motor units, and finally rate coding and recruitment of large motor units

Electrotonic flow of current is faster in small motor neurons than larger motor neurons

Small motor neurons lose current faster than larger motor neurons

Electrotonic flow of current is slower in small motor neurons than larger motor neurons

Small motor neurons produce larger EPSPs than larger motor neurons

Small motor neurons produce larger APs than larger motor neurons
