What two body structures contain flexible elastic cartilage
-
Interstitial
-
The epiglottis
-
External ear cartilage
-
Aeriolar
Correct Answer(s)
A. The epiglottis
A. External ear cartilageExplanation
The epiglottis and external ear cartilage are the two body structures that contain flexible elastic cartilage. The epiglottis is a flap of cartilage located at the base of the tongue, which prevents food and liquid from entering the windpipe during swallowing. External ear cartilage is the cartilage that gives shape and structure to the outer ear, allowing it to be flexible and movable. Both of these structures require flexibility and elasticity to perform their respective functions effectively.Rate this question:

Cartilage grows by interstitial growth. What does this mean?
-
It depends on the specific unit
-
Bilateral
-
Exterior
-
From within
Correct Answer
A. From withinExplanation
Cartilage grows by interstitial growth, which means that it grows from within. This process involves the division and multiplication of chondrocytes, the cells that make up cartilage, within the existing cartilage matrix. As the chondrocytes divide, they produce new matrix material, causing the cartilage to grow from the inside out. This type of growth allows cartilage to expand and maintain its structure, making it an important process for the development and repair of cartilage tissue.Rate this question:

The relationship between skeletal muscles and bones is that skeletal muscles use bones as levers to cause movement in the body and it's parts
-
True
-
False
Correct Answer
A. TrueExplanation
Skeletal muscles and bones have a functional relationship in the body. Skeletal muscles are attached to bones and use them as levers to generate movement. When the muscles contract, they pull on the bones, causing them to move and enabling various actions such as walking, running, or lifting objects. This relationship allows for coordinated movement and provides stability and support to the body. Therefore, the statement that skeletal muscles use bones as levers to cause movement in the body is true.Rate this question:

What two types of substances are stored in bone matrix?
-
Minerals
-
Growth factors
-
Enzymes
-
Protein
Correct Answer(s)
A. Minerals
A. Growth factorsExplanation
Bone matrix is a complex structure that provides strength and support to bones. It consists of various substances, including minerals and growth factors. Minerals, such as calcium and phosphorus, are stored in the bone matrix and contribute to its hardness and rigidity. Growth factors, on the other hand, are proteins that regulate the growth and development of bone cells. They play a crucial role in bone remodeling and repair. Therefore, both minerals and growth factors are stored in the bone matrix to maintain the structural integrity and promote bone growth.Rate this question:

Two functions of a bones marrow cavities are
-
Lacunae
-
Blood cell formation
-
Kittens
-
Fat storage
Correct Answer(s)
A. Blood cell formation
A. Fat storageExplanation
The bone marrow cavities have two main functions. One of them is blood cell formation, where the bone marrow produces different types of blood cells, including red blood cells, white blood cells, and platelets. This process is crucial for maintaining a healthy immune system and ensuring proper oxygenation and clotting in the body. The second function is fat storage, as the bone marrow contains adipose tissue that stores and releases fat cells when needed for energy. These two functions play vital roles in maintaining overall health and homeostasis in the body.Rate this question:

Which membrane lines the internal canals and covers the trabecular of a bone?
-
Periosteum
-
Ossiflex
-
Osteoblasts
-
Endosteum
Correct Answer
A. EndosteumExplanation
The endosteum is a membrane that lines the internal canals and covers the trabecular of a bone. It is composed of a single layer of cells and is responsible for bone growth, repair, and remodeling. The endosteum contains osteoprogenitor cells, which can differentiate into osteoblasts or osteoclasts, and plays a crucial role in regulating bone formation and resorption.Rate this question:

Which component of bone-organic or inorganic- makes it hard?
-
Bone salts
-
Osteocytes
-
Osteoid
-
Osteoblasts
Correct Answer
A. Bone saltsExplanation
Bone salts, also known as inorganic components of bone, are responsible for making it hard. These salts primarily consist of calcium and phosphate minerals, such as hydroxyapatite. They form a dense network of crystals that gives bone its strength and rigidity. In addition to bone salts, bones also contain organic components, such as osteocytes, osteoid, and osteoblasts, which play important roles in bone formation and maintenance, but it is the presence of bone salts that gives bone its hardness.Rate this question:

Which cell has a ruffled border and acts to break down bone matrix?
-
Osteoblasts
-
Osteoclasts
-
Osteocytes
-
Osteoflex
Correct Answer
A. OsteoclastsExplanation
Osteoclasts are cells that have a ruffled border and are responsible for breaking down bone matrix. They are involved in the process of bone resorption, where they release enzymes and acids to dissolve the mineralized matrix of bone. This allows for the remodeling and reshaping of bones, as well as the release of calcium and other minerals into the bloodstream. Osteoblasts, on the other hand, are responsible for bone formation, while osteocytes are mature bone cells that help maintain bone health. Osteoflex is not a recognized cell type involved in bone metabolism.Rate this question:

Bones don't begin with tissue, what do they begin with?
-
Fibrous membranes
-
Aerolar
-
Elastin
-
Hyaline cartilages
Correct Answer(s)
A. Fibrous membranes
A. Hyaline cartilagesExplanation
Bones begin with fibrous membranes and hyaline cartilages. Fibrous membranes, also known as fibrous connective tissue, serve as the initial framework for bone formation. They provide structural support and help in the attachment of muscles to bones. Hyaline cartilages, on the other hand, act as a precursor to bone formation. They are gradually replaced by bone tissue through a process called ossification. So, both fibrous membranes and hyaline cartilages play crucial roles in the development and formation of bones.Rate this question:

The term "bone chases cartilage," means the cartilage model grows and breaks down and is replaced by bone. Is this true or false?
-
True
-
False
Correct Answer
A. TrueExplanation
The term "bone chases cartilage" refers to the process of endochondral ossification, where the cartilage model is gradually replaced by bone. This occurs during the development and growth of long bones in the body. Initially, the cartilage model serves as a template for bone formation, but as growth continues, the cartilage breaks down and is replaced by bone tissue. Therefore, the statement is true.Rate this question:

As long bone grows in length, what is happening in the hypertrophic zone of the epiphyseal plate?
-
Chondrocytes enlarge
-
Recycling
-
Lacunae break down
-
Leave holes in the cartilage matrix
Correct Answer(s)
A. Chondrocytes enlarge
A. Lacunae break down
A. Leave holes in the cartilage matrixExplanation
In the hypertrophic zone of the epiphyseal plate, chondrocytes enlarge, lacunae break down, and leave holes in the cartilage matrix. This is a normal process that occurs during bone growth. As chondrocytes enlarge, they contribute to the lengthening of the bone. The breakdown of lacunae and the creation of holes in the cartilage matrix allow for the invasion of blood vessels and osteoblasts, which eventually replace the cartilage with bone tissue. This process is essential for the growth and development of long bones.Rate this question:

If osteoclasts in a long bone are more active than osteoblasts, how will bone mass change?
-
Bone mass will increase
-
Bone mass will decrees
-
Cancer will form
-
Fibromyalgia will form
Correct Answer
A. Bone mass will decreesExplanation
If osteoclasts, which are responsible for breaking down bone tissue, are more active than osteoblasts, which are responsible for building new bone tissue, the overall balance of bone formation and resorption will be disrupted. This means that more bone tissue will be broken down than is being replaced, leading to a decrease in bone mass.Rate this question:

Which bone disorder is characterized by excessive deposit of weak, poorly mineralized bone?
-
Osteoporosis
-
Osteogenesis Imperfecta
-
Fibrous Dysplasia
-
Pagers disease
Correct Answer
A. Pagers diseaseExplanation
Paget's disease is a bone disorder characterized by excessive deposit of weak, poorly mineralized bone. This condition causes the affected bones to become enlarged and deformed, leading to pain, fractures, and other complications. Osteoporosis, on the other hand, is a condition characterized by a decrease in bone density and strength, but not necessarily excessive bone deposition. Osteogenesis Imperfecta is a genetic disorder that causes brittle and easily fractured bones. Fibrous Dysplasia is a bone disorder where normal bone is replaced with fibrous tissue, but it does not involve excessive deposition of weak bone.Rate this question:

What are three measures that may help to maintain healthy bone density?
-
Relaxing
-
Vitamin D
-
Calcium
-
Weight bearing exercise
Correct Answer(s)
A. Vitamin D
A. Calcium
A. Weight bearing exerciseExplanation
Vitamin D, calcium, and weight-bearing exercise are three measures that may help to maintain healthy bone density. Vitamin D is essential for the absorption of calcium, which is necessary for strong bones. Calcium is a key mineral that supports bone health and helps prevent osteoporosis. Weight-bearing exercise, such as walking or weightlifting, puts stress on the bones, stimulating them to become stronger and denser. These three measures work together to promote healthy bones and reduce the risk of fractures or bone-related diseases.Rate this question:

What name is given to adult rickets?
-
Osteomalacia
-
Osteochondritis Dissecans
-
Osteopetroses
-
Paget disease
Correct Answer
A. OsteomalaciaExplanation
Osteomalacia is the correct answer because it refers to a condition in which the bones become soft and weak due to a vitamin D deficiency or problems with calcium and phosphorus absorption. It is commonly known as adult rickets because it shares similar symptoms and causes with rickets, a condition that affects children. Osteochondritis Dissecans, Osteopetroses, and Paget disease are all different conditions that do not specifically refer to adult rickets.Rate this question:

At what stage of life are most bones well formed and ossified, except for their epiphysis?
-
After 50
-
At 20
-
At birth
-
Puberty
Correct Answer
A. At birthExplanation
At birth, most bones are well formed and ossified, except for their epiphysis. This is because during fetal development, the majority of the skeletal system is formed, and by the time a baby is born, the bones are already well-developed. However, the epiphysis, which are the ends of the long bones, are not fully ossified at birth. Ossification of the epiphysis continues throughout childhood and adolescence, eventually completing around the age of 20. Therefore, at birth is the stage of life when most bones are well formed and ossified, except for their epiphysis.Rate this question:

The decrees in bone mass that begins in the fourth decade of life affects nearly all bones. What are the exceptions?
-
The humerous
-
The skull
-
The clavicle
-
The femur
Correct Answer
A. The skullExplanation
The decrees in bone mass that begins in the fourth decade of life affects nearly all bones except for the skull. This is because the skull is made up of flat bones that do not undergo significant changes in bone mass with age. The humerus, clavicle, and femur are all long bones that are susceptible to the decrease in bone mass that occurs with aging.Rate this question:
