Example Question #31 : Bones
What is the structure of the xiphoid process of a child?
Cartilage
Smooth muscle
Cardiac muscle
Bone
Striated muscle
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?
Humerus
Body of the sternum
Manubrium
Supraspinatus muscle
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 #33 : Bones
What does the sternal angle separate?
Body of the sternum and the xiphoid process
The manubrium and the first rib
Manubrium and the xiphoid process
Manubrium and the body of the sternum
The manubrium and the second rib
Manubrium and the body of the sternum
The sternal angle separates the manubrium and the body of the sternum.
Example Question #34 : Bones
On which portion of the sternum does the first rib insert?
Xiphoid process
Body of the sternum
Clavicle
Manubrium
Humerus
Manubrium
The first rib inserts on the manubrium of the sternum.
Example Question #35 : Bones
Which rib inserts at the sternal angle?
Fifth rib
Fourth rib
Third rib
Second rib
First rib
Second rib
The second rib inserts at the sternal angle. The first rib inserts on the manubrium and the third through six ribs insert on the body of the sternum.
Example Question #36 : Bones
On which portion of the sternum do the third through sixth ribs insert?
Xiphoid process
Body of the sternum
Humerus
Manubrium
Clavicle
Body of the sternum
The third through sixth ribs insert at the body of the sternum. They do not insert at the manubrium, xiphoid process, clavicle, or the humerus.
Example Question #31 : Identifying Bones Of The Trunk And Core
Where is the jugular notch located in the sternum?
Body of the sternum
Clavicle
Humerus
Xiphoid process
Manubrium
Manubrium
The jugular notch, also known as the suprasternal notch is located at the superior portion of the manubrium. It is not located on the body of the sternum, the xiphoid process, the clavicle or the humerus.
Example Question #32 : Identifying Bones Of The Trunk And Core
What joint separates the body of the sternum and the xiphoid process?
Sternal angle
Costoclavicular joint
Coracoclavicular joint
Acromioclavicular joint
Xiphisternal joint
Xiphisternal joint
The xiphisternal joint separates the body of the sternum and the xiphoid process. The sternal angle separates the manubrium and the body of the sternum.
Example Question #33 : Identifying Bones Of The Trunk And Core
The pelvic outlet is bounded by which of the following structures?
Inferior margin of the pubic symphysis and the sacral promontory
Inferior margin of the pubic symphysis and the tip of coccyx
Public tubercle and the ischial tuberosity
Superior margin of the pubic symphysis and the tip of coccyx
Inferior margin of the pubic symphysis and the tip of coccyx
The pelvic outlet is the lower circumference of the lesser pelvis. The pelvic outlet is bounded anterior-posteriorly by the pelvic arch (specifically the inferior margin of the pubic symphysis) and the tip of the coccyx. Laterally it is bound by the ischial tuberosities.
Example Question #34 : Identifying Bones Of The Trunk And Core
How many vertebrae are located in the vertebral column?
33
12
7
5
33
We have seven cervical vertebrae, twelve thoracic vertebrae, five lumbar vertebrae, five fused sacral vertebrae, and four fused coccygeal vertebrae. Adding these numbers tells us that we have thirty-three total vertebrae in our vertebral columns. A good way to remember that there are seven cervical, twelve thoracic, and five lumbar vertebrae is to think of the times that we eat breakfast, lunch, and dinner: 7 AM, 12 PM, and 5 PM.
