1. True or False: The carpal bones are classified as short bones.                 

1. What type of bone has a shaft (diaphysis) and two expanded knoblike ends (epiphyses)?                 

1. The skull is composed of two distinct groups of bones: the cranial bones and the                  bones.

1. The                  vertebrae articulate (form joints) with the ribs.

1. In the fetal skull, the developing cranial bones are connected by areas of fibrous connective tissue called                 .

1. True or False: In a typical vertebra, the pedicles and laminae form the spinous process.

45. What is found within spongy bone that allows for hematopoesis?

46. The vertebral bodies, laminae, and spinous processes of adjacent

vertebrae are held together by what important structures to protect the

spine and spinal cord from injury?

45.

Answer 1

1. Spongy bone does not contain the osteons,Osteon are functional unit of compact bone.Statement is false.

2. Carpal bones are short bones ,as they are almost equal in length and width .Statement is true.

3. A long bone contains the elongated shaft i.e. diaphysis and two expanded knob like ends i.e. Epiphyses.

4.The skull is composed of two distinct groups of bones: the 8 cranial bones and the 14 facial bones.

5. The thoracic vertebrae articulate with ribs through the, thoracic facet present on the vertebrae.

6.In the fetal skull, the developing cranial bones are connected by areas of fibrous connective tissue called fontanelles.

7.In a typical vertebra ,lamina arise from the pedicles and fuse in the back to become a spinous process.Thus statement is True.

8. Costal cartilages of vertebrosternal ribs(true ribs) directly attaches to the sternum .Thus statement is True

9. Flat bones examples are Cranium ,sternum , ilium and Ribs.

10.Long bones examples are Femur, Tibia, Fibula ,Humerus,Radius, and Ulna.

11. Irregular bones are vertebrae, temporal, sphenoid, ethmoid, zygomatic, maxilla, mandible etc.

12. Short bones are Carpal,Tarsals, metacarpals , metatarsals .

45.. Spongy bones consist the red bone marrow in there trabeculae which is involved in hematopoesis.

46.The vertebral bodies, laminae, and spinous processes of adjacent vertebrae are held together by intervertebral discs which protect the spine and spinal cord from injury .
