Answer:
The muscle used to elevate the hyoid bone during swallowing is the <u>Suprahyoid muscles.</u>
Explanation:
<u>Suprahyoid muscles consists of digastric, stylohyoid, geniohyoid, and mylohyoid muscles. These four muscles are located above hyoid bone in neck. </u>
The digastric muscles pull upward on hyoid bone on contracting. The mylohyoid elevates hyoid bone and tenses the mouth's floor. The Geniohyoid pulls hyoid bone anterosuperiorly results in the shortening floor of the mouth and widening pharynx during swallowing. The Stylohyoid elevates and retracts hyoid bone, elongating the mouth's floor.
<u>The functions of all these muscles are different. In general, they assist in elevating the hyoid bone and widening the esophagus while swallowing.</u>
Answer:
The answer to the question: What thoracic muscle is the prime mover of shoulder flexion, would be, A: Pectoralis minor.
Explanation:
The movement, and stability of the shoulder joint, and the arm itself, depends mostly on many muscles and tendons that keep it from coming apart with movement. While all of them work together to protect this joint and permit arm movement, some of them will aid in a certain type of movement, while others will antagonize these first. The important thing here is that as your joint moves, these muscles activate to ensure stability and movement. During flexion, which is literally the movement of bringing the arm closer to the body, there are several muscles that act as synergists, meaning, they act together to ensure correct movement and stability. One such muscle is the pectoralis minor, which arises from the ribs, and then inserts into the coracoid process of the scapula. In conjunction with other muscles, the pectoralis minor will be prime in shoulder flexion, and will be aided by others.
The target heart rate zone is the range of exercise intensity that allows you to stress your cardiorespiratory system for optimal benefit without overloading the system.
The target heart rate of an individual refers to the heartbeat range during exercise and is measured as a percentage. The resting heart rate is calculated by checking the pulse beat for one minute. It normally ranges between 60-100 beats/minute. The target heart rate is 220 subtracted by the age of an individual. For example, the target heart rate for a 27-year-old would be 220-27= 193 beats/minute. Therefore, at a 50% exertion level, the target heart rate must be 50% of the maximum value, that is, 97 beats/minute.
