  1. Skeletal System

  2. Anatomical Postion

  3. Body Planes and Directions

  4. Skeletal SystemTerminology • Osteo-Bone, frame work

  5. Skeletal SystemTerminology • Osteo-Bone • Myel/o- Bone marrow- creates bloods cells

  6. Skeletal SystemTerminology • Osteo-Bone • Myel/o- Bone marrow • Arthr/o- Joints-makes motion possible

  7. Skeletal SystemTerminology • Osteo-Bone • Myel/o- Bone marrow • Arthr/o- Joints- • Chondr/o- Cartilage- creates smooth surface for joints and protects ends of bones

  8. Skeletal SystemTerminology • Osteo-Bone • Myel/o- Bone marrow • Arthr/o- Joints • Chondr/o- Cartilage • Burs/o- Bursae— fluid filled sack that cushions areas subjected to friction

  9. 20 Little Known Facts About The Human Body • A human being loses an average of 40 to 100 strands of hair a day. • A cough releases an explosive charge of air that moves at speeds up to 60 mph. • Every time you lick a stamp, you're consuming 1/10 of a calorie. • A fetus acquires fingerprints at the age of three months. • A sneeze can exceed the speed of 100 mph. • Every person has a unique tongue print. • According to German researchers, the risk of heart attack is higher on Monday than any other day of the week.

  10. Skeletal System • Functions- provides frame work, calcium storage, blood cell formation, movement

  11. Skeletal System • Functions- provides frame work, calcium storage, blood cell formation, movement • 206 bones- a few people will have 205 or 207

  12. Skeletal System • Functions- provides frame work, calcium storage, blood cell formation, movement • 206 bones- a few people will have 205 or 207 • Axial Skeleton- 80 bones, skull, spine, ribs and sternum

  13. Skeletal System • Functions- provides frame work, calcium storage, blood cell formation, movement • 206 bones- a few people will have 205 or 207 • Axial Skeleton- 80 bones, skull, spine, ribs and sternum • Appendicular skeleton- 126 bones, upper and lower extremities, shoulders, and pelvis

  14. After spending hours working at a computer display, look at a blank piece of white paper. It will probably appear pink. • An average human drinks about 16,000 gallons of water in a lifetime. • A fingernail or toenail takes about 6 months to grow from base to tip. • An average human scalp has 100,000 hairs. • It takes 17 muscles to smile and 43 to frown. • Babies are born with 300 bones, but by adulthood we have only 206 in our bodies. • Beards are the fastest growing hairs on the human body. If the average man never trimmed his beard, it would grow to nearly 30 feet long in his lifetime.

  15. Bone structure

  16. Typical Long Bone Epiphysis Diaphysis Epiphysis Epiphysis

  17. Other bone landmarks • Foramen- hole in the bone for blood supply and nutrient transport

  18. Other bone landmarks • Foramen- hole in the bone for blood supply and nutrient transport • Tubercle- bump for tissue attachment

  19. Articulations-Joints

  20. Articulations-Joints • 2 or more bones join together/connect

  21. Articulations-Joints • 2 or more bones join together/connect • Ligaments hold bones together

  22. Types of joints • Suture- immovable joint in the skull

  23. Types of joints • Suture- immovable joint in the skull • Symphysis- moves slightly, connect pubic bones together

  24. Types of joints • Suture- immovable joint in the skull • Symphysis- moves slightly, connect pubic bones together • Synovial – movable joint, most of the joint in the body are synovial

  25. Synovial Joints • A joint capsule surrounds the joint

  26. Synovial Joints • A joint capsule surrounds the joint • Filled with synovial fluid • Lubricates and cushions the joints • Provides nutrients to the joints

  27. Types of Synovial Joints • Ball and Socket—hip and shoulder joints

  28. Types of Synovial Joints • Ball and Socket—hip and shoulder joints • Hinge- knee and elbow

  29. Types of Synovial Joints • Ball and Socket—hip and shoulder joints • Hinge- knee and elbow • Saddle- ankle and thumb- rotation

  30. By age sixty, most people have lost half of their taste buds. • By the time you turn 70, your heart will have beat some two-and-a-half billion times (figuring on an average of 70 beats per minute.) • Each square inch of human skin consists of twenty feet of blood vessels. • Every human spent about half an hour as a single cell. • Every square inch of the human body has an average of 32 million bacteria on it. • Fingernails grow faster than toenails. • Humans shed about 600,000 particles of skin every hour - about 1.5 pounds a year. By 70 years of age, an average person will have lost 105 pounds of skin.

  31. Bone to Memorize • Humerus- • Ulna • Radius • Carpals • Phalanges • Femur, trochanter, head, neck • Patella

  32. Bone to Memorize • Tibia • Fibula • Talus • Calacaneous • Sternum • Xyphoid proccess • Manubrium

  33. Bone to Memorize • Clavicle • Cervical vertebrae • Thoracic Vertebrae • Lumbar Vertebrae • Sagittal sutures • Coronal sutures • Fontanel • Mandible

  34. Bone to Memorize • Tarsals • Metacarpals • Metatarsals • Ilium • Sacrum • Scapula • Ribs- 7 true, 3 false, 2 floating

  35. Extra stuff • Right vs Left- humerus and femur • Hold the bone up to your body, understand the angles and projections • Be able to identify bones from an x-ray

  36. Male vs Femalethe “glass” sign
