A&p Lab Quiz #2

Front 1

The hyoid bone belongs to the

Back 1

axial skeleton

Front 2

The clavicle belongs to the

Back 2

pectoral girdle

Front 3

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

Back 3

It causes weakening in the internal support that the compact bone requires, making the entire bone break.

Front 4

Be able to label canaliculi, lucana, osteon, central canal, lamella

Back 4

Ex. 6 lab

Front 5

The ends of the long bone are known as the

Back 5

epiphyses

Front 6

The radius is a part of which skeletal division?

Back 6

Appendicular

Front 7

The ribs are a part of which skeletal division?

Back 7

Axial

Front 8

What is an osteon?

Back 8

An osteon is the modular unit of bone

Front 9

Describe the nature of decalcified bone. What was removed in the process of decalcification, and what impact did this have on the structure?

Back 9

Decalcified bone that has been placed in an acid and had the calcium salts removed. This weakens the bone and makes it rubbery.

Front 10

Fill in the major bones or bony regions of the body (carpals, clavicle, hip bone, HUMERUS, phalanges)

Back 10

Ex. 6 pg 77

Pituitary gland

Front 14

What are the names of the bones that surround the anterior opening of the nose?

Front 15

In what bone would you find the foramen magnum?

Back 15

Occipital bone

Front 16

Label the following terms of the jaw

Angle, body, condylar process, ramus, etc

Back 16

Ex. 7

Front 17

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

Back 17

Maxilla is thin and around a space, so it's hard. You're also using your maxilla to eat. A fracture in the femur is easier to set because it is a thicker bone.

Front 31

The humerus fits into what specific part of the scapula?

Back 31

Glenoid Cavity

Front 32

What part of the clavicle attaches to the scapula?

Back 32

Acromial end

Front 33

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

Back 33

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.

Front 34

Back 34

Anatomical neck

Front 35
