Study Notes
Types of Joints
- Immovable joints are called fibrous joints.
- Cartilaginous joints allow for slight movement.
- Freely movable joints are classified as synovial joints.
Study of Joints
- The study of joints is known as arthrology.
Joint Anatomy
- The thin, smooth layer of cartilage on articular surfaces is referred to as articular cartilage.
- The fluid-filled space between joint surfaces, enclosed by a fibrous capsule, is known as the joint cavity.
Joint Structures
- Bands of fibrous connective tissue that join bones together and stabilize joints are called ligaments.
- The collection of synovial fluid from a joint for analysis is termed arthrocentesis.
Movement Terminology
- The movement that decreases the angle between two bones is termed flexion.
- The twisting movement of a part on its axis is referred to as rotation.
- The synovial joint movement that allows movement in a circle at the distal end of an extremity is known as circumduction.
- Movement of the limb towards the median plane is called adduction.
- Movement of the limb away from the median plane is termed abduction.
Bone Composition
- Lightweight yet strong bone is classified as spongy bone.
- The outer layer of the periosteum is composed of dense irregular connective tissue.
- Compact bone makes up the shafts of long bones and the outer layer of all bones.
Bone Cells and Functions
- Osteoblasts are responsible for bone formation and the secretion of bone matrix.
- The intercellular matrix of bone primarily consists of collagen fibers and mineral content.
- Osteoclasts function in the resorption of bone tissue.
- The endosteum serves to line the inner surface of bones and is involved in bone growth and remodeling.
Periosteum and Bone Matrix
- The periosteum functions to protect bones, serve as an attachment point for muscles, and facilitate the supply of blood to the bone.
- The basic composition of the bone matrix includes organic components (collagen) and inorganic mineral salts (hydroxyapatite).
Structural Features of Bone
- Tightly compacted cylinders of bone, known as osteons, consist of concentric layers of ossified bone matrix arranged around a central canal, housing osteocytes between the layers.
