Question

Which of the following muscle names and their naming descriptors is not correctly matched?

a. adductor brevis // short muscle that moves bone closer to the midline
b. rectus abdominis // muscle with fibers parallel to the midline of the abdomen
c. levator scapula // muscle that raises the scapula
d. intercostal // muscle associated with the rib cage
e. all of the above are correctly matched

Answer 1

All the muscle names given are correctly matched with their naming descriptors: Adductor brevis is short and brings a bone closer to the midline, Rectus abdominis has fibers parallel to the midline, Levator scapula elevates the scapula, and Intercostal muscles are associated with the rib cage.

Step-by-step explanation:

The naming of skeletal muscles in human anatomy is often based on several characteristics, including muscle size, shape, location, direction of fibers, and the bones they are associated with. Correctly matching muscle names with their descriptors is essential for understanding their function and anatomy.

Name Matching Review

• Adductor brevis - This muscle is indeed a short muscle that moves a bone closer to the midline of the body, so it is described accurately.
• Rectus abdominis - The muscle fibers run parallel to the midline of the abdomen, meaning its name correctly describes its character.
• Levator scapula - Appropriate for a muscle that raises (elevates) the scapula (shoulder blade).
• Intercostal - The intercostal muscles are located between the ribs; hence, they are correctly described as being associated with the rib cage.

Option e. all of the above are correctly matched - This is the correct answer, as all the muscle names listed are appropriately matched with their naming descriptors.
