Textbook Question

Match the bone markings listed on the right with their function listed on the left.
1. Attachment site for muscle or ligament
2. Forms a joint surface
3. Passageway for vessels or nerves
a. Trochanter

Verified step by step guidance

Understand the problem: You are tasked with matching the bone marking 'Trochanter' with its function. Bone markings are specific features on bones that serve distinct purposes, such as attachment sites, joint surfaces, or passageways.

Recall the definition of a 'Trochanter': A trochanter is a large, blunt, irregularly shaped projection found on the femur. It serves as an attachment site for muscles and ligaments.

Analyze the functions provided: The functions listed are (1) Attachment site for muscle or ligament, (2) Forms a joint surface, and (3) Passageway for vessels or nerves. Based on the definition of a trochanter, it is primarily associated with function (1).

Eliminate irrelevant functions: A trochanter does not form a joint surface (function 2) or serve as a passageway for vessels or nerves (function 3). These functions are typically associated with other bone markings like condyles or foramina.

Conclude the match: The trochanter is best matched with function (1), 'Attachment site for muscle or ligament,' based on its anatomical role.

Key Concepts

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

Bone Markings

Bone markings are specific features on bones that serve various functions, including attachment points for muscles and ligaments, joint formation, and pathways for nerves and blood vessels. Understanding these markings is crucial for identifying how bones interact with other structures in the body.

Trochanter

A trochanter is a large, bony prominence found on the femur, specifically serving as an attachment site for muscles. There are two main trochanters: the greater and lesser, which provide leverage and stability for muscle action, particularly in the hip region.

Joint Surfaces

Joint surfaces are the areas of bones that come into contact with each other to form joints. These surfaces are often smooth and covered with cartilage to facilitate movement and reduce friction, playing a vital role in the overall function and mobility of the skeletal system.
