Define and explain the following:
$(1)$ Skeletal muscles
$(2)$ Visceral muscles

(N/A) $(1)$ Skeletal muscles: These muscles are closely associated with the skeletal components of the body,such as the head,trunk,and limbs. Due to this association,they are termed skeletal muscles. They are typically striated and under voluntary control.
$(2)$ Visceral muscles: These muscles are located in the inner walls of hollow visceral organs of the body,such as the alimentary canal (digestive system),respiratory tract,and reproductive tract. They are smooth in appearance and are under involuntary control.
