  1. Body & Mind – Yoga Skeletal system Dan Jakes 2010

  2. Structure of bone (long bone) Dan Jakes 2010

  3. Skeletal System • Support • Storage of minerals and lipids • Blood production • Protection • leverage

  4. Types of bone • Long (e.g. thigh bone) • Short (e.g. wrist bones) • Flat (e.g. ribs) • Irregular (e.g. vertebrae) • Sesamoid (e.g. knee cap) Dan Jakes 2010

  5. Axial Skeleton • consists of the 80 bones in the head and trunk of the human body. It is composed of five parts • Skull • Inner ear bones • Hyloid • Ribs • Spine Dan Jakes 2010

  6. Appendicular skeleton composed of 126 bones 1) Pectoral Girdle 2) Arm and Forearm 3) Hands 4) Pelvis 5) Thigh and leg 6) Feet Dan Jakes 2010

  7. Cranium Clavicle Sternum Scapula Humerus Spine Pelvis Ulna Femur Carpals Metacarpals Patella Phalanges Fibula Tibia Tarsals Talus Metatarsals Phalanges Dan Jakes 2010

  8. Other tissues in the Skeletal system • Cartilage (Cartilage is a stiff yet flexible tissue found on joint surfaces to provide less friction or more flexibility for movement) • Ligaments (strong bands of protein fibers that connect bone to bone) • Tendons (strong band that connect muscle to bone) • Can you think of examples of each? Dan Jakes 2010

  9. Yoga and Bone • Hatha Yoga is arguably the ‘original physiotherapy’ • Exercise increases bone mass in postmenopausal women. The key is that you must exercise consistently—at least 30 minutes a day, five days a week. • “It stimulates bone remodeling and “improves the absorption of calcium from the intestine and promotes its deposition on the bones.” In particular, weight-bearing exercises are what stimulate the bones to retain calcium and produce more bone mass. By contrast, swimming, which can help joint pain and limited mobility, does nothing to increase bone density in the spine.” (http://www.yogajournal.com, retrieved 23/2/10) • Yoga improves alignment and posture which takes stress off joints and other structures to improve skeletal health Dan Jakes 2010

  10. Links to other systems • Provides levers for the muscular system to act on • Provides ions (e.g. ca++ for muscle contraction) • Provides support & protection for nervous system • Endocrine system regulate bone growth and deterioration • Bone Marrow produces blood cells for cardiovascular system, while cardiovascular system provides nutrients, minerals and removes waste • Protects lungs • Protects organs of digestive system while digestive system provides nutrients for bone growth and repair • Reproductive system has an impact on the production of hormones that regulate bone development Dan Jakes 2010
