Study Notes
Joint Movement and Types
- Supination: A type of rotation allowing palm to face upward.
- Flexion: Decreases angle between two bones; extension increases it.
- Abduction: Movement away from the body's midline; adduction moves toward the midline.
- Circumduction: Combines flexion, extension, abduction, and adduction in a circular motion.
- Rotation: Movement of bones around a central axis.
- Diarthrosis: Freely movable joints; amphiarthrosis: partially movable; synarthrosis: immovable.
Bone Structure and Function
- Bones in the skull are flat bones; the cranium protects the brain.
- Red marrow is where blood cells are formed; bones store minerals like calcium and phosphorus.
- Articular cartilage is smooth cartilage covering joint surfaces; articular capsule encloses joints.
Skeletal Anatomy
- Axial skeleton comprises the skull, vertebral column, hyoid, sternum, and ribs.
- Appendicular skeleton includes shoulder girdles, arms, wrists, hands, pelvic girdle, legs, ankles, and feet.
- The bone forming the base of the skull is the frontal bone; the key bone of the skull is the sphenoid.
Joint Types and Components
- Pivot joints are located in the shoulder; immovable joints are found in an infant's skull.
- Ligaments connect bones and cartilage; tendons connect muscle to bone.
- The point of contact between two bones is referred to as a joint.
Health Conditions
- Fracture: Break in the bone; dislocation: bone displacement in a joint; sprain: joint injury from sudden motion.
- Arthritis: Inflammatory condition affecting one or more joints; rheumatoid arthritis is chronic and autoimmune.
- Osteoarthritis: Degeneration of articular cartilage; gout is due to uric acid deposits in joints.
- Rickets: Softening of bones from Vitamin D deficiency.
Spine and Posture
- Kyphosis: Humped curvature in the thoracic spine; lordosis: exaggerated inward curvature in the lumbar region; scoliosis: lateral curvature of the spine.
Other Key Terms
- Calcaneus: Heel bone; femur: longest, strongest bone in the body; mandible: only movable bone in the face.
- Ribs attached directly to the sternum are called true ribs; the bones of the wrist are known as carpals.
- The radius is located on the thumb side of the arm.
