4. SKELETAL MUSCLE Skeletal muscle, striated in structure and under voluntary control, is anchored by tendons  to bone and is used to effect  skeletalmovement such as locomotion and to maintain posture. An average adult male is made up of 42% of skeletal muscle and an average adult female is made up of 36% (as a percentage of body mass ).  It also has striations unlike smooth muscle.

5. SMOOTH MUSCLE & CARDIAC MUSCLE Smooth muscle, neither striated in structure nor under voluntary control, is found within the walls of organs and structures such as the  esophagus , stomach,  intestines,bronchi , uterus, urethra, bladder, blood vessels Cardiac muscle (myocardium), found only in the heart, is a striated muscle similar in structure to skeletal muscle but not subject to voluntary control.
