  • The epiphysis is the rounded end of a long bone.
  • The diaphysis is the shaft or midsection of a long bone.
  • The diaphysis is the shaft or midsection of a long bone.
  • There are three types of joints: fibrous joints, cartilaginous joints, and synovial joints.
  • Synovial fluid lubricates the joint cavity and reduces friction during movement.
  • Hyaline cartilage covers the ends of most bones and forms the articular surfaces of some joints.
  • Fibrocartilage connects bones at intervertebral discs.
  • The two divisions of the skeletal are the axial skeleton and the appendicular skeleton
  • Long Bones have a shaft called the diaphysis with epiphyses at either end
  • Appendicular Skeleton consists of the upper limbs (arms) and lower limbs (legs)
  • Short Bones are roughly cubical in shape
  • Flat Bones are thin and flat, such as those that form the skull
  • Irregular Bones do not fit into any other category
  • Axial Skeleton is made up of the skull, vertebral column, rib cage, sternum, and hyoid bone
  • Flat Bones consist of thin plates that protect organs or form parts of joints
  • Irregular Bones do not fit into any other category and include the sphenoid bone of the cranium and the sacrum and coccyx of the pelvis
  • Flat Bones consist of thin plates that protect organs, such as the skull or rib cage

  • The skeleton system has 206 bones
  • The sutures of the skull are the coronal, lambdoid, and squamous suture.
  • The coccyx at the inferior end of the sacrum is composed of several fused vertebrae
  • The ribs are attached posteriorly to the vertebral column
  • The thoracic cage is composed of 12 pairs of ribs
  • The humerus, radius and ulna articulate to form the elbow joint
  • Condyle: a rounded process of a bone that articulates with another bone. Ex: Occipital Condyle
  • Crest: A narrow, ridgelike projection Ex: Iliac crest of illium
