Study Notes
Joints and Connective Tissue
- Suture: Immovable joint; primarily found between skull bones.
- Synovial Joint: Freely movable joint, encased in a membrane that secretes lubricating synovial fluid.
- Ligament: Tough connective tissue band that links one bone to another in a joint area.
- Tendon: Fibrous tissue connecting muscle to bone, facilitating movement.
- Bursa: Synovial fluid-filled sac near joints, reducing friction between tissues and bones.
- Meniscus: C-Shaped fibrocartilaginous structure in the knee, providing cushioning and support.
Joint Function and Health Issues
- Synovial Fluid: Viscous, egg white-like fluid that nourishes and lubricates joints.
- Arthritis: General term for joint inflammation, affects mobility and comfort.
- Ankylosing Spondylitis: Progressive arthritis that causes spine joint stiffness.
- Gout: Painful condition from uric acid crystal accumulation in joints, commonly affects the big toe.
- Osteoarthritis: Age-related joint wear and tear, primarily impacts large joints (knees, hips, spine).
- Rheumatoid Arthritis: Autoimmune condition that thickens and inflames synovial membranes, often starts in smaller joints.
Conditions Related to the Musculoskeletal System
- Bunion: Benign increase in bone/soft tissue at the big toe base, often due to incorrect-fitting shoes.
- Carpal Tunnel Syndrome: Median nerve compression at the wrist, leading to numbness in thumb and fingers, often from repetitive strain.
- Subluxation: Partial dislocation of a bone from its joint, leading to misalignment and discomfort.
- Ganglion Cyst: Fluid-filled sac on tendons or joint capsules, typically found in wrist, hand, or knee.
- Herniated Disc: Protrusion of intervertebral disc into the spinal canal, causing nerve pressure and pain.
Systemic Conditions Affecting Joints
- Lyme Disease: Caused by tick bites leading to recurring arthritis and muscle pain; treated with antibiotics.
- Sprain: Joint injury affecting ligaments, resulting in pain and swelling.
- Strain: Muscle injury due to overstretching, leading to discomfort and limited movement.
- Systemic Lupus Erythematosus: Autoimmune disorder impacting collagen across the body, causing joint pain, fever, and a characteristic skin rash.
