4.3- Muscle Roles and Types of Contraction 3 Quiz Please sign up for the course before taking this quiz. A muscle is behaving as an agonist when:1 It contracts while lengthening. It contracts to initiate movement. It relaxes to initiate movement. The two ends of it move away from each other. A muscle contraction is isometric when:1 The distance between the two ends of the muscle stays the same. The distance between the two ends of the muscle increases. The distance between the two ends of the muscle decreases. It remains relaxed at its neutral length. A muscle contraction is concentric when:1 The distance between the two ends of the muscle stays the same. The distance between the two ends of the muscle increases. The distance between the two ends of the muscle decreases. All muscle contractions are concentric. A muscle contraction is eccentric when:1 The distance between the two ends of the muscle stays the same. The distance between the two ends of the muscle increases. The distance between the two ends of the muscle decreases. All muscle contractions are eccentric. When a muscle is behaving as a stabilizer, it is:1 never contracted. always contracted. It is not possible to know if a stabilizer is contracted without more information. sometimes contracted. When a muscle is behaving as an agonist, it is:1 It is not possible to know if an agonist is contracted without more information. never contracted. always contracted. sometimes contracted. A muscle is behaving as a stabilizer when:1 It contracts to initiate movement. It contracts while allowing movement to happen. It relaxes to initiate movement. It contracts to prevent movement from happening. A muscle is behaving as an antagonist when:1 It contracts to keep a joint from moving. It relaxes to initiate movement. It contracts to initiate movement. It lengthens to allow movement. When a muscle is behaving as an antagonist, it is:1 always contracted. It is not possible to know if an antagonist is contracted without more information. sometimes contracted. never contracted. In this transition, the bone at 2 is brought toward the bone at 1. That means that muscles between those bones are in which role?1Tadasana to Urdhva Hasta in Tadasana Agonist Antagonist Possible agonist or antagonist Stabilizer In this transition, the muscles between which bones are behaving as antagonists?1Tadasana to Urdhva Hasta in Tadasana The bone at 1 and the bones at 2 The bone at 2 and the bones at 4 The bone at 2 and the bones at 3 In this transition, the muscles between which bones are behaving as stabilizers?1Tadasana to Urdhva Hasta in Tadasana The bone at 2 and the bone at 4 The bone at 3 and the bone at 4 The bone at 2 and the bone at 3
