Appendicular Skeleton, and Joints
This overview explores the types of joints within the appendicular skeleton, with a detailed focus on the knee joint. Joints are classified into three main categories: Synarthrotic (non-movable), Amphiarthrotic (slightly movable), and Diarthrotic (freely movable), with the knee being a prime example of a diarthrotic joint. We will delve into the anatomy and function of the knee joint, including its synovial structure, ligaments, and the roles of key muscles like the quadriceps, providing a comprehensive understanding of its complexities.

Lab # 5 Appendicular Skeleton, and Joints
TYPES OF JOINTS (Martini, pages 267-268) 1- Synarthrotic (fibrous) They are non-movable. They have no joint cavity or capsule. Articulating bones are held together by fibrous tissue. Ex: sutures and syndesmoses 2- Amphiarthrotic (cartilaginous) They are slightly movable. They have no joint cavity or capsule. Bones are held together by cartilage and ligaments. Ex: Symphyses pubis 3- Diarthrotic or Synovial They are freely movable. Articulating bones are covering by a thin layer of articulating cartilage. The bones are joined by a fibrous capsule lined by a synovial membrane, and by ligaments
