Chapter 5: Flexibility and Lower Back Health Flashcards
The full motion possible in a joint.
Range of Motion
A technique in which a muscle is slowly and gently stretched and then held in the stretched position.
Static Stretching
Semielastic structures, composed primarily of connective tissue, that surround major joints.
Joint capsules
A disorder of the joints characterized by joint pain, stiffness, and inflammation. Osteoarthritis, the most common form, is a degenerative joint disease. Rheumatoid arthritis is an autoimmune disease that typically affects the hands and feet.
Arthritis
White fibers that provide structure and support in connective tissue.
Collagen
Yellow fibers that make connective tissue flexible.
Elastin
Temporary change in the length of muscles, tendons, and supporting connective tissues.
Elastic Elongation
Long-term change in the length of muscles, tendons, and supporting connective tissues.
Plastic Elongation
A nerve that sends information about the muscular and skeletal systems to the nervous system.
proprioceptor
A muscle that opposes the action of another. For example, the biceps brachius muscle (agonist) flexes the elbow, while the triceps brachius (antagonist) extends the elbow.
Antagonist Muscle
A technique in which muscles are stretched by the force generated as a body part is repeatedly bounced, swung, or jerked.
Ballistic Stretching
A technique in which muscles are stretched by moving joints slowly and fluidly through their range of motion in a controlled manner; also called functional stretching.
Dynamic Stretching
A technique in which muscles are stretched by force applied by an outside source.
Passive Stretching
A technique in which muscles are stretched by the contraction of the opposing muscles.
Active Stretching
Bony segments composing the spinal column that provide structural support for the body and protect the spinal cord.
Vertebrae
