Correctly label the following features of the muscle filament. Thin filament Head Actin Tail Thick filament
b) Which of the following are true statements about myosin? Select all the true statements. Each myosin head has a binding site for actin and ATP The interaction between myosin and actin converts chemical energy to mechanicall work muscle contraction, thick and thin filaments slide past each other causing an overall lengthening of the muscle. In a muscle cell, myosin tails group together to form a thick filament The myosin-actin reaction cycle is powered by ATP hydrolysis The tail of...

To demonstrate an understanding of the myofilaments, place the labels the correct location on the image. Myosin tail Thin filament ATP Tropomyosin Myosin head ADP Actin Thick filament Actin-binding Troponin
Muscle contraction: Select one O a occurs when myosin pulls on actin and the sarcomere shortens b. occurs when actin pushes on myosin and the sarcomere elongates O c occurs when the myosin tail splits the actin filament in half Od occurs when actin and myosin entangle, generating more distance between Z lines
Label the image of a skeletal muscle fiber below. Actin Muscle fascicle Muscle fiber Muscle (organ) Myosin Myofibril Sarcomere
true or false the striations in skeletal muscle are formed by tge arrangement of thick and thin filament
correctly label the following anatomical features of a tibiofemural
joint
Correctly label the following anatomical features of the tibiofemoral joint. Fibular collateral ligament Fibula Patellar ligament (cut) Posterior cruciate ligament Anterior cruciate ligament Tibial collateral ligament Lateral meniscus Medial meniscus Tibia Femur (a) Anterior view Lateral condyle This tissue attaches the patella to the tibia. < Prev 14 of 15 !!!

_________ or thin filaments interact with _________ or thick filaments during muscle contractions.
Correctly label the following features of the foot. Medial malleolus Calcaneal tendon Lateral longitudinal arch Calcaneus Head of metatarsal Head of fibula Medial longitudinal arch Lateral malleolus
8 Number the following events of skeletal muscle contraction in the proper order, with number 1 for the first event and number 6 for the last event. A power stroke occurs as myosin moves into its relaxed position and pulls the thin filament toward the M line. Calcium ions bind to troponin, which pulls tropomyosin away from actin. ATP breaks the actin-myosin attachment, after which ATP is hydrolyzed and myosin is recocked. The myosin head binds to an actin subunit....
(15). Muscle cells contain , which are composed of thin filaments made of ts made ofarranged as thousands of . Myosin is a motor protein that moves towards the WWwe end of actin. and eNN Calcium is stored in specialized endoplasmic reticulum called released in response to depolarization of the . Calcium binds to MMMN , uncovering the myosin binding which results in a conformational change in sites on actin. Binding of ATP to myosin causes the hydrolysis of ATP...
