Understanding the Skeletal and Musculoskeletal Systems

These flashcards cover key vocabulary related to the skeletal and musculoskeletal systems, including definitions of various types of bones, structures, and functions.

Long Bones

Bones that have a bulbous end and a shaft in the middle; examples include the femur and humerus.

Short Bones
