Question
Evaluate how the name of a muscle can distinguish its location, action, shape, and function. Select five different muscles to make this distinction.
Examine the principal axial muscles of the body and distinguish their origins, insertions, actions, and innervations.
Examine the principal appendicular muscles of the body and distinguish their origins, insertions, actions, and innervations
Evaluate the major muscle groups of the upper and lower limbs and relate their similarities and differences to their function.
Explanation / Answer
1. Modern medical science was evolved with specific Universal terminology. Depend upon the anatomical position of the body part, specific prefixes, suffixes are used to locate its position verbally, this terminology is very useful for remembering names and position of body organs.
For the ease of remembering, skeletal muscles are named based on different criteria. They are,
The names of the following muscles are based on the criteria given below.
1. Gluteus maximus: Location of the muscle relative to a bone or body region (e), and relative size of the muscle.
2. Adductor magnus: Action of the muscle, and relative size of the muscle.
3. Biceps femoris: Number of origins, and Location of the muscle relative to a bone or body region.
4. Transverses abdominis: Location of the muscle relative to a bone or body region, and direction in which the muscle fibres run relative to some imaginary line.
5. Extensor carpi ulnaris: Action of the muscle, Location of the muscle relative to a bone or body region, and location of the origin.
6. Trapezius: Shape of the muscle.
7. Rectus femoris: Location of the muscle relative to a bone or body region, and direction in which the muscle fibres run relative to some imaginary line.
8. External oblique: Location of the muscle relative to a bone or body region, and direction in which the muscle fibres run relative to some imaginary line .
