Example Question #21 : Identifying Bones Of The Trunk And Core
Which of the following types of vertebrae tend to be fused in the adult skeleton?
Cervical
A healthy adult skeleton does not contain fused vertebrae
Lumbar
Thoracic
Sacral
Sacral
The sacral vertebrae, generally 4-6 in number, are fused in the adult to form the sacrum. Additionally, the coccygeal vertebrae are fused in many individuals to form the coccyx. These are the two types of vertebra that are typically fused in the adult skeleton.
The cervical, thoracic, and lumbar vertebrae do not fuse under normal circumstances.
Example Question #22 : Bones
Which of the following types of vertebrae are the smallest weight-supporting vertebrae?
Lumbar
Coccygeal
Cervical
Sacral
Thoracic
Cervical
The cervical vertebrae are the smallest weight-supporting vertebra. The coccygeal and terminal sacral vertebrae are smaller, but they support no weight. The thoracic and lumbar vertebrae are larger in size.
Example Question #22 : Identifying Bones Of The Trunk And Core
The first seven ribs are __________ ribs.
visceral
false
true
appendicular
floating
true
The first seven ribs are true ribs, in that they articulate with the sternum at the readily observable costal (rib) notches. The 8th, 9th, and 10th ribs are false ribs in that they do not articulate directly with the sternum, but with a cartilage which articulates with the sternum. The 11th and 12th ribs are floating ribs, in that they do not connect at all to the sternum.
Example Question #23 : Identifying Bones Of The Trunk And Core
The 11th and 12th ribs are __________ ribs.
floating
true
false
articular
appendicular
floating
The 11th and 12th ribs are floating ribs, in that they do not connect at all to the sternum. The first seven ribs are true ribs, in that they articulate with the sternum at the readily observvable costal (rib) notches. The 8th, 9th, and 10th ribs are false ribs in that they do not articulate directly with the sternum, but with a cartilage which articulates with the sternum.
Example Question #24 : Identifying Bones Of The Trunk And Core
The 8th, 9th, and 10th ribs are __________ ribs.
false
appendicular
somatic
true
floating
false
The 8th, 9th, and 10th ribs are false ribs in that they do not articulate directly with the sternum, but with a cartilage which articulates with the sternum. The first seven ribs are true ribs, in that they articulate with the sternum at the readily observable costal (rib) notches. The 11th and 12th ribs are floating ribs, in that they do not connect at all to the sternum.
Example Question #25 : Identifying Bones Of The Trunk And Core
The number of vertebrae in the cervical, thoracic, and lumbar spine, respectively, are: __________, __________, __________.
twelve . . . seven . . . five
twelve . . . five . . . seven
seven . . . twelve . . . five
five . . . seven . . . twelve
seven . . . five . . . twelve
seven . . . twelve . . . five
The cervical spine has 7 vertebrae, the thoracic has 12, and the lumbar has 5.
Example Question #21 : Bones
How many components are there to the sternum?
Five
Two
Three
Four
One
Three
The sternum is composed of 3 separate portions: the manubrium, the body of the sternum, and the xiphoid process.
Example Question #26 : Identifying Bones Of The Trunk And Core
What is the most inferior portion of the sternum?
Clavicle
Xiphoid process
Body of the sternum
Humerus
Manubrium
Xiphoid process
The most inferior portion of the sternum is the xiphoid. The most superior portion of the sternum is the manubrium. The body of the sternum is just inferior to the manubrium. The clavicle and the humerus are not part of the sternum.
Example Question #27 : Identifying Bones Of The Trunk And Core
What is the middle portion of the sternum known as?
Clavicle
Xiphoid process
Body of the sternum
Manubrium
Humerus
Body of the sternum
The middle portion of the sternum is the body of the sternum. The most superior portion of the sternum is the manubrium. The xiphoid process is the most inferior portion of the sternum. The clavicle and the humerus are not part of the sternum.
Example Question #28 : Identifying Bones Of The Trunk And Core
What is the most superior portion of the sternum?
Manubrium
Xiphoid process
Humerus
Clavicle
Body of the sternum
Manubrium
The most superior portion of the sternum is the manubrium. The body of the sternum is just inferior to the manubrium. The xiphoid process is the most inferior portion of the sternum. The clavicle and the humerus are not part of the sternum.
