Question 1

A bone marking that consists of a hole through which vessels,nerves,and ligaments pass is called a

Accepted Answer

The term "foramen" specifically refers to a hole or opening in a bone through which other structures such as vessels, nerves, and ligaments can pass. The other options listed do not necessarily involve a hole or opening.

Question 2

Which type of bone makes up the dense,hard outer shell?

Accepted Answer

Compact bone is the dense, hard outer shell of bones. It is made up of tightly packed layers of bone tissue that provide strength and protection. Cancellous bone, on the other hand, is the spongy interior of bones that contains bone marrow. Marrow is a soft, gelatinous tissue found inside bones that produces blood cells. The periosteum is a thin layer of connective tissue that covers the outer surface of bones.

Question 3

A bone marking that consists of a rounded anterior projection is called a

Accepted Answer

A rounded anterior projection is typically a feature of a bone's head, which often articulates with another bone to form a joint. For example, the head of the femur articulates with the acetabulum of the hip bone to form the hip joint. A foramen is a hole through a bone, a crest is a narrow ridge, and a fossa is a shallow depression.

Question 4

How many bones make up the human skeleton?

Accepted Answer

There are 206 bones in the human skeleton.

Question 5

The membrane that surrounds the bone and contains nerves and blood vessels is the

Accepted Answer

The periosteum is a tough fibrous membrane that surrounds the bone and contains nerves and blood vessels. It also contains cells responsible for bone growth and repair. The epiphysis refers to the ends of long bones, while the medullary canal is the central cavity of long bones that contains bone marrow. The metaphysis refers to the area of the bone where growth plates are located during development.

Question 6

The scapula is an example of which type of bone?

Accepted Answer

The scapula, also known as the shoulder blade, is a flat bone. Flat bones are thin and flattened, providing a surface for muscle attachment and protection of underlying organs.

Question 7

The type of bone that makes up most of the appendicular skeleton is the

Accepted Answer

Long bones are the primary type of bone found in the appendicular skeleton, which includes the bones of the arms, legs, hips, and shoulders. These bones have a long, cylindrical shape and are characterized by a diaphysis (shaft) and two epiphyses (rounded ends). Examples of long bones include the femur, humerus, and tibia.

Question 8

Which of the following is a function of the skeletal system?

Accepted Answer

The skeletal system has multiple functions including providing shape and support, protecting vital organs such as the brain and heart, and manufacturing blood cells in the bone marrow. Therefore, all of the choices are correct.

Question 9

The structure of the bone where growth occurs is the

Accepted Answer

The epiphyseal plate, also known as the growth plate, is the area of the bone where growth occurs, particularly in adolescents. The diaphysis is the main shaft of the bone, the medullary canal is the hollow space within the diaphysis, and the endosteum is the lining of the medullary canal. None of these structures are directly involved in growth.

Question 10

A bone marking that consists of a sharp ridge or border is called a

Accepted Answer

A crest is a sharp ridge or border along the surface of a bone. Foramen refers to a hole in a bone, head refers to a rounded end of a bone, and fossa refers to a shallow depression on a bone's surface.

Question 11

A skeletal pathology characterized by pain in the knee area due to issues with traction epiphysis is which of the following?

Accepted Answer

Osgood-Schlatter disease is a condition that causes pain in the knee area due to issues with the traction epiphysis. It typically affects adolescents who are undergoing growth spurts and involves inflammation and microfractures at the site where the patellar tendon inserts into the tibia. Slipped femoral capital epiphysis is a separate condition that involves the femoral head slipping from its normal position at the top of the thighbone and is not associated with knee pain. Osteoporosis is a condition characterized by decreased bone density, while osteomyelitis is a bone infection that can lead to bone pain but is not specifically associated with the knee area.

Question 12

A bone marking that consists of a hollow or depression is called a

Accepted Answer

A fossa is a bone marking that consists of a hollow or depression. A foramen is a small hole in a bone, a crest is a ridge or projection on a bone, and a head is a rounded end of a bone.
