Muscular System
This structural component of skeletal muscle is composed of bundles of muscle fibers.
What is a muscle fascicle?
These tough, fibrous tissues connect bones to other bones in joints.
What are ligaments?
Sarcopenia is characterized by the loss of this in skeletal muscle.
What is muscle mass?
Osteopenia is a condition characterized by lower bone mineral density but not to the extent of this condition.
What is osteoporosis?
This common type of arthritis often affects the small joints of the hands and feet.
What is rheumatoid arthritis?
These contractile units within muscle fibers are responsible for muscle contraction.
What are sarcomeres?
Tendons connect muscles to these skeletal components.
What are bones?
One symptom of sarcopenia is a decline in this, making daily activities more challenging.
What is physical strength or mobility?
People with osteoporosis are at greater risk of experiencing these types of fractures.
What are hip and vertebral fractures?
This type of arthritis primarily affects children and adolescents.
What is juvenile rheumatoid arthritis?
This molecule binds to calcium ions, allowing myosin to interact with actin during muscle contraction.
What is troponin?
Bone mineral density measures the concentration of these minerals in bones.
What are calcium and phosphorus?
The majority of muscle mass loss in sarcopenic patients is to these regions.
What are the arms and legs?
Osteoporosis can lead to a reduced quality of life due to increased risk of these health issues.
What are fractures, pain, and limited mobility?
Rheumatoid arthritis is characterized as this type of disease, involving the body's immune system.
What is an autoimmune disease?
During muscle contraction, this molecule releases stored calcium ions.
What is the sarcoplasmic reticulum?
This type of fiber makes up the composition of tendons and ligaments.
What are collagen fibers?
Sarcopenia may increase the risk of falls and fractures due to this factor.
What is reduced muscle stability and balance?
This medical imaging technique is commonly used to measure bone mineral density.
What is Dual-energy X-ray absorptiometry (DXA or DEXA)?
Rheumatoid Arthritis is the inflammation of these structures in the joints.
What are synovial membranes?
This energy system primarily uses glycogen and is dominant during short to moderate durations of moderate to high-intensity exercise.
What is the glycolytic (anaerobic) energy system?
Synovial fluid lubricates and nourishes this part of a joint.
What is the synovial membrane and cartilage?
This type of exercises is recommended to help maintain muscle mass and reverse atrophy.
What is resistance training?
The loss of this hormone in aging females is associated with greater risks of osteoporosis.
What is estrogen (estradiol)?
Osteoarthritis primarily affects this joint component.
What is cartilage?
