Refers to bone mineral density (BMD) that is lower than normal peak BMD but not low enough to be classified as osteoporosis.
Irreversible decrease in mineralized bony tissue.
Growth by the addition of new layers on those previously formed. Characteristic of tissue formed of rigid materials.
Process of bone formation whereby a cartilage model is replaced by bone.
Transverse cartilage plate near the end of a child's bone responsible for growth in length of the bone.
The volume of bone in the body measured by mineral content.
Bone mineral density
The mineral content in a given volume of bone, used as a measure of bony health and in the diagnosis of osteoporosis.
A point of articulation between two or more bones, especially such a connection that allows motion.
Consist of two bones that are united by fibrous tissue and exhibit little or no movement.
Unites two bones by means of either hyaline cartilage or fibrocartilage.
Contain synovial fluid and allow for considerable movement between articulating bones.
A tough, elastic, fibrous connective tissue found in various parts of the body, such as the joints, outer ear, and larynx.
Cartilage that allows for greater movement capabilities due to its flexible nature.
A plate or ring of fibrocartilage attached to the joint capsule and separating the articular surfaces of the bones.
A sac enclosing a joint, formed by an outer fibrous membrane and an inner synovial membrane.
The dense fibrous membrane covering the surface of bones except at the joints and serving as an attachment for muscles and tendons.
Tough fibrous band of connective tissue that supports internal organs and holds bones together properly in joints.
A tough band of fibrous connective tissue that connects muscles to bones.
A layer of connective tissue which lines the joint and produces synovial fluid.
A tiny fluid-filled sac that functions as a gliding surface to reduce friction between tissues of the body.
Describes joints that stretch further than is normal
Thickened connective tissue that envelops a muscle or a group muscles.
Thread-like fibrils that make up the contractile part of a striated muscle fiber.
Filaments, made up of actin and myosin, that are the structural units of a myofibril.
A contractile protein in muscle cells, responsible for the elastic and contractile properties of muscle. It is commonly referred to as the thick contractile protein.
A protein found in muscle that together with myosin functions in muscle contraction. It is commonly referred to as the thin contractile protein.
Anterior curvature of the spine, creating a swayback appearance.
An abnormal convex (outward) curvature of the upper portion of the spinal column, sometimes called a humpback or hunchback.
A spinal position that retains the three natural curves: a small lordotic curve at the base of the neck, a small kyphotic curve at the middle back, and a small lordotic curve in the low back.
A fibrocartilaginous disc serving as a cushion between the vertebrae of the spinal column.
Anterior pelvic tilt
Anterior pelvic movement, originating from the lumboscacral joint and affecting the curvature of the spine.
Posterior pelvic tilt
A posterior pelvic movement, originating from the lumboscacral joint and affecting the curvature of the spine.
