Answer #1

Answer:

Skeletal muscle contraction:

Skeletal muscle contraction Smooth muscle contraction
Contraction is voluntary Contraction is involuntary
Contraction occurs via activation of myosim binding site in actin by calcium attachment Contraction involves the Myosin Light Chain Kinase activation
Contractile unit is called motor unit Contractile unit is called single unit or multiple unit depending upon the number of fibers activated by an action potential
Its contraction is regulated by the somatic motor neurons contraction is regulated by autonomic motor neurons
They have short refractory period hence they gets fatigued very early They have long refractory period hence they do not get fatigued
