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.
Example Question #241 : Gross Anatomy
On which portion of the sternum does the first rib insert?
Manubrium
Clavicle
Humerus
Body of the sternum
Xiphoid process
Manubrium
The first rib inserts on the manubrium of the sternum.
Example Question #242 : Gross Anatomy
Which rib inserts at the sternal angle?
Fourth rib
Fifth rib
First rib
Second rib
Third 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 #243 : Gross Anatomy
On which portion of the sternum do the third through sixth ribs insert?
Body of the sternum
Xiphoid process
Manubrium
Clavicle
Humerus
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 #244 : Gross Anatomy
Where is the jugular notch located in the sternum?
Clavicle
Body of the sternum
Xiphoid process
Humerus
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 #245 : Gross Anatomy
What joint separates the body of the sternum and the xiphoid process?
Xiphisternal joint
Acromioclavicular joint
Costoclavicular joint
Sternal angle
Coracoclavicular 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 #31 : Bones
The pelvic outlet is bounded by which of the following structures?
Public tubercle and the ischial tuberosity
Inferior margin of the pubic symphysis and the tip of coccyx
Inferior margin of the pubic symphysis and the sacral promontory
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 #32 : Bones
How many vertebrae are located in the vertebral column?
12
33
5
7
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.
