Three types of Muscle Tissue correct answers -Skeletal -Cardiac -Smooth Skeletal Muscle Tissue correct answers striated and voluntary/skeleton smooth muscle tissue correct answers Involuntary muscle is found in the intestines where it pushes food along the digestive tract. Also found in arteries and veins. cardiac muscle correct answers Involuntary muscle tissue found only in the heart. Anatomy of Skeletal Muscle correct answers Muscle -- Fascicles -- Muscle Cells/Fibers -- Myofibrils -- myofilaments connective tissue of skeletal muscle correct answers epimysium, perimysium, endomysium Plasmalemma (cell membrane) correct answers Fuses with tendon Conducts action potential Maintains pH, transports nutrients satellite cells correct answers involved in muscle growth and development aids response to injury, immobilization, training sarcoplasm correct answers cytoplasm of a muscle cell Transverse tubules (T-tubules) correct answers -Serve as extensions of plasmalemma. -Carry action potential deep into muscle fiber. sarcoplasmic reticulum correct answers stores calcium sarcomere correct answers Contractile unit of muscle Sarcomeres (protein filaments) correct answers -muscle contractions -actin (thin filaments) -myosin (thick filaments) a-motor neuron correct answers neurons that carry outgoing information from the brain and spinal cord to the muscles and glands steps of muscle fiber contraction: excitation-contraction coupling correct answers 1. Action Potential (AP) starts at brain 2. AP arrives at axon terminal, releases acetylcholine (ACh) 3. ACh crosses neuromuscular junction, binds to ACh receptors on plasmalemma 4. AP travels down plasmalemma and T-tubules
