Bone Markings

Which description best defines a bone "head" as shown in the image of the humerus?

• Flat surface for tendon passage

• Bony expansion carried on a narrow neck that forms part of a joint

• Depression that allows nerve travel

• Large, rough projection for muscle attachment

In the context of bone markings, what is the primary function of a head?

• Increase marrow storage

• Form part of a joint by articulating with another bone

• Provide passage for blood vessels

• Serve as a site for fracture repair

Which statements correctly characterize a tubercle? Select all that apply.

• It is a small, rounded projection or process.

• It primarily forms a synovial joint surface.

• It serves as a point of attachment for connective tissue.

• It is always flat and smooth.

Match each bone marking to its typical feature or function.

• Bony expansion on a narrow neck; forms part of a joint

• Tuberosity

• Small rounded projection; attachment for connective tissue

• Tubercle

• Large rounded projection; may be rough; muscle/ligament attachment

• Head

Which example correctly identifies tubercles on the humerus?

• Medial and lateral epicondyles

• Greater and lesser tubercles

• Deltoid tuberosity and radial groove

• Olecranon and coronoid processes

A tuberosity is best described as which of the following?

• Small rounded projection that forms a joint surface

• Large rounded projection that may be rough and serves as a muscle/ligament attachment site

• Deep pit for vessel passage

• Thin ridge for nerve anchoring

Which bone marking on the humerus is specifically a site for muscle attachment and may present a rough surface?

• Head of humerus

• Intertubercular sulcus

• Deltoid tuberosity

• Greater tubercle

Which comparison between tubercle and tuberosity is accurate?

• Both are small rounded projections mainly forming joint surfaces.

• A tubercle is larger and rougher than a tuberosity.

• A tubercle is small and rounded; a tuberosity is larger and may be rough, with both serving as attachment sites.

• Neither is involved in connective tissue attachment.

Which statement best defines a trochanter as shown in the femur diagram?

• A small, sharp ridge that forms joint surfaces

• A very large, blunt, irregularly shaped process found only on the femur

• A rounded depression that accommodates hyaline cartilage

• A narrow passage for blood vessels in long bones

In the proximal femur image, which structure is specifically identified as a muscle attachment site and is unique to the femur?

• Greater trochanter

• Medial epicondyle

• Capitulum

• Coronoid process
