L1: Skeletal system

• What are the organ structures in skeletal system?

  • Bones, cartilage, and joints
  • Axial Skelton
  • Appendicular skeleton
  • Bone
  • Bone marrow
• What is the primary function of cartilage?

  Bone interfaces (blue)

  • Types: hyaline (ribs, joints);fibro (so that bone doesnt rub on bone and there is cushion)
• What is the primary function of axial skeleton?

  Protects brain and spinal cord, sense organs, and soft tissues of thorax.

  Support body weight over lower limbs
• What is the primary function of appendicular skeleton?

  Provides internal support and positioning of the external limbs; supports and enables muscles to move the axial skeleton.
• What is the primary function of skeletal system?

  Provides support; protects tissuesl stores minerals; firms blood cells
• What is in the axial skeleton?

  Skull, vertebrae, sacrum, coccyx, sternum, supporting cartilages, ligaments
• What is included in the appendicular skeleton?

  Limb bones, supporting cartilages & ligaments
• What is the primary function of bone?

  Store minerals
• What is involved in the bone marrow?

  Red and yellow
• Red blood cell production (flat bones( pelvis, sternum, skull, ribs; lose some of this with aging).
• Yellow bone marrow found in the long bone, and converted to make red blood cells. Gain with aging; yellow to red after major bleeding.
