To determine:
The words that are commonly used for naming the muscle and denoting their characteristics.
Introduction:
Muscle provides strength, balance, and posture to the body. The three types of muscle found in vertebrates are skeletal, smooth, and cardiac muscles. Cardiac and smooth muscles are involuntary, while skeletal muscles are voluntary.
Explanation of Solution
The terms that can be used for the muscles based on their different sizes are brevis, longus, major, maximus, minimus, and minor. One of the examples of usage of these terms is pectoralis major. The other examples include gluteus maximus, pectoralis minor, and pectoralis major.
The terms that can be used for the muscles based on their different shapes are deltoid, quadrates, rhomboid, teres, and trapezius. One of the examples of usage of these terms is rhomboid major. The other examples include pronator quadrates, pronator teres, and trapezius.
The terms that can be used for the muscles based on their different locations are abdominis, carpi, cervicis, digiti, and intercostal. One of the examples of usage of these terms is rectus abdominis. The other examples include semispinalis cervicis, external intercostals, and extensor digiti minimi.
The terms that can be used for the muscles based on their different numbers of heads are biceps, triceps, and quadriceps. One of the examples of usage of these terms is triceps brachii. The other examples include biceps femoris and quadriceps femoris.
The terms that can be used for the muscles based on their different orientations are obliques and rectus. The examples of usage of these terms are external oblique and rectus abdominis. The terms that can be used for the muscles based on their different actions are abductor, adductor, depressor, extensor, and supinator. One of the examples of usage of these terms is abductor digiti minimi. The other examples include adductor pollicis, depressor anguli oris, extensor carpi radialis, and supinator.
Thus, the terms that can be used for categorizing the muscles based on their shapes are deltoid, quadrates, rhomboid, teres, and trapezius. The terms for categorizing the muscles based on their sizes are brevis, longus, major, maximus, minimus, and minor. The terms based on their actions are abductor, adductor, depressor, extensor, and supinator.
