Example Question #23 : Bones
The 11th and 12th ribs are __________ ribs.
true
floating
appendicular
articular
false
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 : Bones
The 8th, 9th, and 10th ribs are __________ ribs.
somatic
false
appendicular
floating
true
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 : Bones
The number of vertebrae in the cervical, thoracic, and lumbar spine, respectively, are: __________, __________, __________.
seven . . . five . . . twelve
twelve . . . seven . . . five
seven . . . twelve . . . five
five . . . seven . . . twelve
twelve . . . five . . . seven
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 : Bones
What is the most inferior portion of the sternum?
Body of the sternum
Xiphoid process
Humerus
Clavicle
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 : Bones
What is the middle portion of the sternum known as?
Body of the sternum
Xiphoid process
Clavicle
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 : Bones
What is the most superior portion of the sternum?
Body of the sternum
Manubrium
Xiphoid process
Clavicle
Humerus
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.
Example Question #31 : Bones
What is the structure of the xiphoid process of a child?
Striated muscle
Cardiac muscle
Cartilage
Smooth muscle
Bone
Cartilage
The xiphoid is composed of cartilage in children. By adulthood, this cartilage has undergone ossification and is replaced by bone.
Example Question #32 : Bones
On which portion of the sternum do the clavicles insert?
Supraspinatus muscle
Body of the sternum
Humerus
Manubrium
Xiphoid process
Manubrium
The clavicles insert in the most superior portion of the sternum known as the manubrium. The clavicles do not insert into the body of the sternum, the xiphoid process, the humerus, or the supraspinatus muscle.
Example Question #237 : Gross Anatomy
What does the sternal angle separate?
The manubrium and the second rib
The manubrium and the first rib
Manubrium and the xiphoid process
Body of the sternum and the xiphoid process
Manubrium and the body of the sternum
Manubrium and the body of the sternum
The sternal angle separates the manubrium and the body of the sternum.
