106

206

306

None of the above

The human body has 206 bones. This is the correct answer because the average adult human skeleton consists of 206 bones. These bones provide structure, support, and protection to the body. They also allow for movement and serve as attachment points for muscles.

2. Red Marrow in large bones produces new blood cells.

True

False

The red marrow found in large bones is responsible for producing new blood cells. This is a true statement because red marrow contains stem cells that can differentiate into various types of blood cells, including red blood cells, white blood cells, and platelets. These blood cells are essential for carrying oxygen, fighting infections, and promoting clotting. Therefore, the red marrow plays a crucial role in maintaining a healthy blood supply in the body.

3. Cranial and Facial bones create the skull.

True

False

The statement is true because the cranial and facial bones together form the structure of the skull. The cranial bones include the frontal, parietal, temporal, occipital, sphenoid, and ethmoid bones, which protect the brain. The facial bones, including the maxilla, mandible, zygomatic, nasal, and lacrimal bones, form the framework of the face and protect the sensory organs such as the eyes, nose, and mouth. Together, these bones provide support and protection for the brain and facial structures, making the statement true.

4. The two types of bone are _____ and _____.

Broken and NonBroken

Compact and Spongy

Healed and Unharmed

Thin and Thick

The correct answer is "Compact and Spongy." Bones are composed of two main types of tissue: compact bone and spongy bone. Compact bone is dense and hard, making up the outer layer of most bones. It provides strength and support. Spongy bone, also known as cancellous or trabecular bone, is found inside the compact bone and is lighter and less dense. It contains a network of trabeculae, which gives it a spongy appearance. Spongy bone helps to reduce the weight of the skeleton and provides space for bone marrow.

5. The sternum is also the _____.

Backbone

Hipbone

Breastbone

Arm bone

The sternum is commonly known as the breastbone. It is a flat bone located in the center of the chest, connecting the ribs together. It plays a crucial role in protecting the heart, lungs, and major blood vessels.

Explanation

The sternum is commonly known as the breastbone. It is a flat bone located in the center of the chest, connecting the ribs together. It plays a crucial role in protecting the heart, lungs, and major blood vessels.

6. The three types of rubs are True Ribs, False Ribs, and _____.

Floating Ribs

Neutral Ribs

Attached Ribs

Missing Ribs

The three types of rubs are True Ribs, False Ribs, and Floating Ribs. True Ribs are directly attached to the sternum, False Ribs are indirectly attached to the sternum, and Floating Ribs are not attached to the sternum at all.

Explanation

The three types of rubs are True Ribs, False Ribs, and Floating Ribs. True Ribs are directly attached to the sternum, False Ribs are indirectly attached to the sternum, and Floating Ribs are not attached to the sternum at all.

7. The types of marrow are _____ and _____.

Red and Blue

Red and White

Red and Yellow

Red and Green

The types of marrow are red and yellow.

Explanation

The types of marrow are red and yellow.

8. The sternum protects the heart, lungs, and _____ from damage.

Major blood vessels

Stomach

Kidneys

Intestines

The sternum is a flat bone located in the center of the chest. It acts as a protective shield for vital organs such as the heart and lungs. In addition to these organs, the sternum also protects major blood vessels that are crucial for the circulation of blood throughout the body. Therefore, the correct answer is major blood vessels.

In addition to these organs, the sternum also protects major blood vessels that are crucial for the circulation of blood throughout the body. Therefore, the correct answer is major blood vessels.

9. There are more bones in an adult body than a child's.

True

False

The statement is false because children have more bones than adults. This is because some of the bones in a child's body fuse together as they grow, resulting in a decrease in the total number of bones. Therefore, the number of bones in an adult body is actually less than the number of bones in a child's body.

10. The Axial Skeleton includes:

Cranium, ribcage, spine, pelvic girdle

Arms, legs, and spine

Arms, legs and pelvic girdle

Cranium, ribcage, spine

The correct answer is cranium, ribcage, spine. The axial skeleton is composed of the bones that form the central axis of the body, including the skull (cranium), the ribcage, and the spine. These bones provide support and protection for vital organs such as the brain, heart, and lungs. The arms, legs, and pelvic girdle are part of the appendicular skeleton, which is responsible for movement and locomotion.
