\n\n\n\n12) Muscles that hold the scapula firmly in place while the forearm moves are called:<\/strong><\/h3>\n\n\n\n
Fixators are muscles that stabilize the origin of the prime mover, allowing for efficient and precise movement. In this case, muscles like the trapezius<\/strong> and rhomboids<\/strong> hold the scapula in position, ensuring that the arm and forearm movements can occur smoothly. Without these stabilizing muscles, the scapula would move excessively, disrupting the arm’s functionality.<\/p>\n\n\n\n
\n\n\n\n13) This name reveals the number of the muscle’s origins:<\/strong><\/h3>\n\n\n\n
The term “biceps” means “two heads,” indicating that the muscle has two points of origin. Similarly, “triceps” refers to three heads, and “quadriceps” refers to four heads. The biceps brachii<\/strong> originates from the scapula at two points: the supraglenoid tubercle and the coracoid process.<\/p>\n\n\n\n
\n\n\n\n14) The names of these muscles tell you their actions:<\/strong><\/h3>\n\n\n\n
Muscle names often describe their functions. For example, the adductor magnus<\/strong> adducts the thigh, while the extensor digitorum<\/strong> extends the fingers. In contrast, names like “gluteus maximus” describe size or location, not action.<\/p>\n\n\n\n
\n\n\n\n15) A runner suffers from a pulled hamstring. Which of these muscles might be involved?<\/strong><\/h3>\n\n\n\n
The biceps femoris<\/strong>, part of the hamstring group, works alongside the semitendinosus and semimembranosus to flex the knee and extend the hip. A pulled hamstring typically involves one or more of these muscles.<\/p>\n\n\n\n
\n\n\n\n16) An agonist for elbow flexion is<\/strong>, whereas the antagonist<\/strong> to this movement is:<\/h3>\n\n\n\n
The biceps brachii<\/strong> is the primary muscle (agonist) responsible for elbow flexion, while the triceps brachii<\/strong> serves as the antagonist, counteracting the movement by extending the elbow.<\/p>\n\n\n\n
\n\n\n\n17) The _ is a synergist of the latissimus dorsi; it extends, medially rotates, & adducts the humerus:<\/strong><\/h3>\n\n\n\n
The teres major<\/strong> assists the latissimus dorsi<\/strong> in its movements, including extending, adducting, and medially rotating the humerus.<\/p>\n\n\n\n
\n\n\n\n18) Spasms of this “straplike” muscle often result in wryneck or torticollis:<\/strong><\/h3>\n\n\n\n
The sternocleidomastoid<\/strong> muscle runs along the neck and is responsible for head rotation and flexion. Spasms in this muscle can lead to torticollis, a condition characterized by abnormal head tilt.<\/p>\n","protected":false},"excerpt":{"rendered":"
