Textbook Question

Which criterion (or criteria) is/are used in naming the gluteus medius?
a. Relative size
b. Muscle location
c. Muscle shape
d. Action
e. Number of origins

Verified step by step guidance

Step 1: Understand the naming conventions for muscles. Muscles are named based on specific criteria such as size, location, shape, action, and number of origins. These criteria help describe the muscle's characteristics and function.

Step 2: Analyze the name 'gluteus medius.' The term 'gluteus' refers to the location of the muscle, which is in the gluteal region (buttocks). This indicates that muscle location is one of the criteria used in naming this muscle.

Step 3: Examine the term 'medius.' This word refers to the relative size of the muscle, as 'medius' means middle or intermediate in size compared to other muscles in the same group (e.g., gluteus maximus and gluteus minimus). This indicates that relative size is another criterion used in naming this muscle.

Step 4: Consider the other criteria listed in the problem. The gluteus medius is not named based on its shape, action, or number of origins, as these characteristics are not explicitly described in its name.

Step 5: Conclude that the criteria used in naming the gluteus medius are 'relative size' and 'muscle location,' based on the analysis of the terms 'gluteus' and 'medius.'

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Muscle Naming Criteria

Muscles are often named based on specific criteria that describe their characteristics. These criteria include relative size, location, shape, action, and number of origins. Understanding these criteria helps in identifying and categorizing muscles in the human body.

Gluteus Medius

The gluteus medius is a muscle located on the outer surface of the pelvis. It plays a crucial role in hip stabilization and movement. Its name reflects its position and size relative to other gluteal muscles, which is essential for understanding its function and anatomical significance.

Muscle Location

Muscle location refers to the specific anatomical position of a muscle within the body. In the case of the gluteus medius, its name indicates that it is situated in the gluteal region, specifically between the gluteus maximus and minimus. This criterion is vital for identifying muscles based on their spatial relationships.
