Skeletal Muscle Tissue:

Skeletal Muscle defined as voluntary striated muscle that is usually attached to one or more bones defined as voluntary striated muscle that is usually attached to one or more bones usually called muscle fibers or myofibrils. usually called muscle fibers or myofibrils. fibers packed with protein microfilaments that overlap each other in such a way as to produce alternating light and dark bands, or striations. fibers packed with protein microfilaments that overlap each other in such a way as to produce alternating light and dark bands, or striations. Because of these striations, skeletal muscle appears striped Because of these striations, skeletal muscle appears striped

Skeletal Muscle, cont’d only muscle tissue that is voluntary because it is usually subject to conscious control, although sometimes it is activated by our reflexes. only muscle tissue that is voluntary because it is usually subject to conscious control, although sometimes it is activated by our reflexes. cells have many nuclei, so we call it multinucleate cells have many nuclei, so we call it multinucleate located in your skeletal muscles- the ones that attach to your bones to create organismal movement. located in your skeletal muscles- the ones that attach to your bones to create organismal movement. Key words for skeletal muscle are skeletal, striated, multinucleate, and voluntary. Key words for skeletal muscle are skeletal, striated, multinucleate, and voluntary.
6
Cardiac Muscle:
7
Cardiac Muscle also striated also striated involuntary- not normally under conscious control. involuntary- not normally under conscious control. Its cells are not fibrous in shape. Its cells are not fibrous in shape. They only have one nucleus, so we call the cardiac muscle cells uninucleate. They only have one nucleus, so we call the cardiac muscle cells uninucleate. It is only found in one place in the body- the heart. It is only found in one place in the body- the heart. The key words for cardiac muscle are cardiac, striated, uninucleate, and involuntary. The key words for cardiac muscle are cardiac, striated, uninucleate, and involuntary.
8
Smooth Muscle:
9
Smooth Muscle no striations in smooth muscle no striations in smooth muscle involuntary involuntary located mainly in the walls of hollow visceral organs such as the stomach, urinary bladder and respiratory passages. located mainly in the walls of hollow visceral organs such as the stomach, urinary bladder and respiratory passages. It propels blood through our blood vessels, which are also made from smooth muscle. It propels blood through our blood vessels, which are also made from smooth muscle. uninucleate, like cardiac muscle. uninucleate, like cardiac muscle. Key words for smooth muscle are visceral, nonstriated, involuntary, and uninucleate. Key words for smooth muscle are visceral, nonstriated, involuntary, and uninucleate.
