Overview of the Skeleton Packet

 

1.

    1. sharp, slender process = spine

    2. small rounded projection = tubercle

    3. large rounded projection = tuberosity

    4. structure supported on a neck = head

    5. armlike projection = ramus

    6. rounded, convex projection = condyle

    7. canal-like structure = meatus

    8. opening through a bone = foramen

    9. shallow depression = fossa

    10. air-filled cavity = sinus

    11. large, irregularly shaped projection = trochanter

 

2. The four major anatomical classifications of bones are long, short, flat, and irregular. Which category has the least amount of spongy bone relative to its total volume? long bones

 

3.

  Long Short Flat Irregular
Humerus X

5.

    1. Site of spongy bone in the adult = C, epiphysis

    2. Site of compact bone in the adult = A, diaphysis

    3. Site of hematopoiesis in the adult = C, epiphysis, & D, red marrow

    4. Scientific name for the bone shaft = A, diaphysis

    5. Site of fat storage in the adult = A, diaphysis, & E, yellow marrow cavity

    6. Site of longitudinal growth in a child = B, epiphyseal plate
