The hyoid bone belongs to the |
axial skeleton |
|
The clavicle belongs to the |
pectoral girdle |
|
In the disease osteoporosis, there is a significant loss of cancellous bone. Explain how the loss of this specific bone material can weaken a bone |
It causes weakening in the internal support that the compact bone requires, making the entire bone break. |
|
Be able to label canaliculi, lucana, osteon, central canal, lamella |
Ex. 6 lab |
|
The ends of the long bone are known as the |
epiphyses |
|
The radius is a part of which skeletal division? |
Appendicular |
|
The ribs are a part of which skeletal division? |
Axial |
|
What is an osteon? |
An osteon is the modular unit of bone |
|
Describe the nature of decalcified bone. What was removed in the process of decalcification, and what impact did this have on the structure? |
Decalcified bone that has been placed in an acid and had the calcium salts removed. This weakens the bone and makes it rubbery. |
|
Fill in the major bones or bony regions of the body (carpals, clavicle, hip bone, HUMERUS, phalanges) |
Ex. 6 pg 77 |
|
The eyebrows are superficial to what bone? |
Frontal Bone |
|
What is the common name for the zygomatic bone? |
Cheek bone |
|
What occupies the depression in the sella turcica? |

|
Label the following terms of the jaw Angle, body, condylar process, ramus, etc |

Why would a fractured maxilla create more problems, in terms of bone healing, than a fractured femur? |

|
List all the fontanels in the fetal skull |

|
Which one of the fontanels is the most dorsal? |

What part of the rib articulates with the transverse process of vertebra? |
The tubercle |
|
The most inferior portion of the sternum is the |
Xiphoid |
|
The most superior part of the sternum is the |
manubrium |
|
Match the vertebrae from a region with the features or structures found there Cervical a. ala Coccyx b. vertebrae with the largest vertebral bodies Lumbar c. vertebrae with rib facets Sacral d. typically four fused vertebrae Thoracic e. Transverse foramina |
cervical (e) coccyx (c) Lumbar (b) Sacral (a) Thoracic (d) |
|
The humerus fits into what specific part of the scapula? |
Glenoid Cavity |
|
What part of the clavicle attaches to the scapula? |
Acromial end |
|
The clavicle is broken when the arms are extended to brace a fall. Explain how hitting the ground with your hands can break the clavicle |
The force from the fall will effect the wrist and forearm, then the pressure will keep going until it hits the thin clavicle bone which will break it. |

Trochlear Notch |

Trapezium |
|
Name the roughened line that runs along the length of the posterior femur |
