A&P Lab Midterm: Overview of the Skeleton

  1. What are the five functions of the skeletal system?
    • Supports  the body as an internal framework
    • Protects vital organs
    • Used as a system of levers with which the skeletal muscles work to move the body
    • Bones store lipids and minerals
    • Provides a site for hematopoiesis(blood cell formation)
  2. How many bones are in the adult skeleton?
    206
  3. What color is used to represent the location of hyaline cartilage?

  6. What is the difference between a compact bone and a spongy bone?
    Compact bone look smooth and homogeneous; spongy bone(or calcellous) is composed of small trabeculae(bars) of bone and lots of open space.
  7. Where is a compact bone and a spongy bone found in the skeletal system?
    • Spongy bone is mainly found on the epiphysis of the long bones
    • Compact bone is mainly found in the diaphysis of the long bone.
  8. Name 2 short bones
    • Tarsals
    • Carpals
  9. Describe short bones.
    Roughly cube like, they contain more spongy bone than compact.
  10. Name 2 long bones.
    • Femur
    • Phalanges
  11. Describe long bones.
    Much longer than they are wide, generally consist of a shaft with heads at either end.
  12. Describe irregular bones.
    Bones that do not classify as any of the other clasifications.
  13. Describe sesamoid bones.
    A special type of short bone that form in a tendon.
  14. Describe flat bone.
    Generally thin, with two wafer-like layers of compact bone sandwiching a layer spongy bone between them.
  15. Name a sesamoid bone.
    Patella(knee cap)
  16. Name a flat bone.
    • Sternum

    • Canal-like passageway
    • Image Upload 14
  29. Describe the bone marking fossa
    • Shallow basin-like depression in a bone, often serving as an articular surface
    • Image Upload 15
  30. Describe the bone marking tubercle
    • Small rounded projection or process
    • Site for muscle and ligament attachment
    • Image Upload 16
  31. Describe the bone marking fissure
