Skeletal muscle

Vedclass · Answer

(A) Skeletal muscles are voluntary muscles that are attached to the skeleton. They undergo rapid contraction and relaxation,leading to the accumulation of lactic acid due to anaerobic respiration during strenuous activity. This accumulation of lactic acid causes muscle fatigue. In contrast,cardiac muscles are fatigue-resistant due to their long refractory period and abundant mitochondria,and smooth muscles are slow-acting and fatigue-resistant.
