HOW WELL DO YOU KNOW YOURSELF
Start
31/40
The condition which the bones become weak and break easily is called as ……
d) Clubfoot
c) Osteoporosis
b) Arthritis
a) Osteoarthritis
right answer
Osteoporosis is a disease that weakens the bones and have a greater risk for sudden and unexpected bone fractures. Risk factors for osteoporosis include low body weight, smoking, aging, menopause and some medications. This disease may be prevented by taking more calcium and vitamin D and do exercise.
32/40
Which statement correctly identifies a similarity between cartilage and bone?
c) Both are produced by specialized mesenchymal cells
d) Both are avascular.
a) Both are sites of haematopoiesis
b) Both are innervated
right answer
The Haversian canals of bones provide pathways for nerves and blood vessels. Cartilage does not contain a structure comparable to Harversian canals. Haematopoiesis occurs within red bone marrow. The cells that produce cartilage (chondrocytes) and the cells that produce bone (osteoblasts) are both specialized mesenchymal cells. Mesenchymal cells are undifferentiated connective tissue cells, able to become osteoblasts, chondrocytes, and adipocytes..
33/40
Which bone is the longest and strongest bone in the human body?
d) Radius
c) Tibia
b) femur
a) cranium
right answer
The femur, or thigh bone, is the longest, heaviest, and strongest bone in the body. Its proximal end articulates with the acetabulum of the hip bone. Its distal end articulates with the tibia and patella. The main function of the femur is weight bearing and stability of gait..

which of the following statements are true?
b) II only
a) I , II and III
d) II, III and V
e) III , IV and V
c) IV only
right answer
The pectoral girdle consists of clavicle and scapula. The pectoral girdles do not articulate with the vertebral column and are held in position and stabilized by a group of large muscles that extend from the vertebral column and ribs to the scapula. The anterior component of the pectoral girdle is the clavicle while posterior component of the pectoral girdle is the scapula. t..
35/40
What type of bone undergoing intramembranous ossification?
c) clavicle
b) humerus
d) femur
a) tibia
right answer
The process of bone formation from fibrous membranes is known as intramembranous ossification. The flat bones of the skull, the mandible, and the clavicles are all formed by it.
36/40
In endochondral ossification, where is the primary ossification center located?
c) distal epiphysis
b) metaphysis
d) promixal epiphysis
a) middle of diaphysis
right answer
It is made up of cortical bone and contains adipose tissue and bone marrow (fat). It's a tubular centre section made of compact bone that surrounds a central marrow cavity with red or yellow marrow. Primary ossification occurs in the diaphysis..
37/40
Cartilage is a precursor to many bones throughout the embryonic stages. What cells are required to cause the differentiation of cartilage to bone?
c) Osteoblasts
b) Osteocytes
a) Osteoclasts
right answer
Osteoblasts are bone cells that are important for producing bone matrix proteins and minerals during early embryonic bone development, as well as controlling bone growth and mineralization throughout life..
38/40
Fibrous membranes and cartilage combine to form bone. Which of the following terms describes the formation of bone from cartilage?
c) b) Intramembranous ossification
b) Endochondral ossification
a) Periosteal ossification
right answer
The embryonic cartilaginous model of most bones contributes to longitudinal development and is gradually replaced by bone through the process of endochondral ossification.
39/40
There are five steps of intramembranous ossification. What is D?
c) Secondary ossification centers develop in the epiphyseal region after birth
a) Blood vessels form the red marrow
b) Replacement of hyaline cartilage with bone
right answer
As the osteoid continues to be secreted by osteoblasts, it surrounds blood vessels forming trabecular, cancellous and spongy bone and this vessels will eventually form the red bone marrow. .
40/40
Which of the following lists the zones of endochondral ossification in the correct order?
c) Maturation, proliferation, resting, ossification, calcification
d) Proliferation, maturation, resting, calcification, ossification
b) Proliferation, calcification, maturation, ossification, resting
a) Resting, proliferation, maturation, calcification, ossification
right answer
There are five zones in regions of endochondral ossification. These are the resting zone, the zone of proliferation, maturation, calcification and ossification. .

There are five steps of intramembranous ossification. What is D?
c) Secondary ossification centers develop in the epiphyseal region after birth
a) Blood vessels form the red marrow
b) Replacement of hyaline cartilage with bone
right answer
As the osteoid continues to be secreted by osteoblasts, it surrounds blood vessels forming trabecular, cancellous and spongy bone and this vessels will eventually form the red bone marrow. .

Which of the following lists the zones of endochondral ossification in the correct order?
c) Maturation, proliferation, resting, ossification, calcification
d) Proliferation, maturation, resting, calcification, ossification
b) Proliferation, calcification, maturation, ossification, resting
a) Resting, proliferation, maturation, calcification, ossification
right answer
There are five zones in regions of endochondral ossification. These are the resting zone, the zone of proliferation, maturation, calcification and ossification. .
