Aim: To understand the identification and description of long bones

Materials Needed:

Table of Contents

  • Skeletal models or specimens of long bones (femur, humerus, radius, ulna, tibia, fibula)
  • Labels or markers
  • Notebooks and pens

Procedure:

Carefully observe the bone and identify its key features such as:

  • Diaphysis (shaft)
  • Epiphysis (ends)
  • Metaphysis (region between diaphysis and epiphysis)
  • Articular surfaces
  • Medullary cavity

DescriptionOnce the bones are identified by the key features, describe each feature in detail. This can include:

  • Size and shape of the bone
  • Location and appearance of the diaphysis, epiphysis, and metaphysis
  • Surface characteristics (smooth, rough, etc.) of the bone
  • Presence of any markings such as ridges, tubercles, or foramina
  • Articular surfaces and their orientations
  • Presence of nutrient foramina
  • Type and arrangement of bone tissue (compact or spongy)

The importance of understanding long bone anatomy in fields such as anatomy, anthropology, and forensic science.
