Skeletal and Muscular System Questions
-
Nervous tissue
-
Epithelial tissue
-
Connective tissue
-
Muscle tissue
C
Correct answer
Explanation
Cartilage is a type of connective tissues composed of special cells known as chondrocytes along with collagen or yellow elastic fibres. The fibres and the cells are embedded in a firm gel like matrix rich in mucopolysaccharides. Cartilage is not as hard and rigid as bone. It is much more flexible and elastic.
-
Hyaline
-
Fibrous
-
Elastic
-
Neuron
D
Correct answer
Explanation
A neuron is an electrically excitable cell that processes and transmits information by electrical and chemical signalling. Chemical signalling occurs via synapses, specialized connections with other cells/
-
Chondrocytes
-
Osteocytes
-
Osteoblasts
-
Osteocalcin
A
Correct answer
Explanation
Chondrocytes are the only cells found in cartilage. They produce and maintain the cartilaginous matrix, which consists mainly of collagen and proteoglycans.
-
Periosteum
-
Osseous tissue
-
Endosteum
-
Bone marrow
D
Correct answer
Explanation
Bone marrow is the flexible tissue found in the interior of bones. In humans, marrow in large bones produces new blood cells. It constitutes 4% of the total body mass of humans, i.e. , approximately 2.6 kg (5.7 lbs.) in adults weighing 65 kg or 143 lbs. Bone marrow also prevents the backflow of lymph, working as a vital part of the lymphatic system.
-
It is insensitive
-
It contains blood vessels
-
It is surrounded by the perichondrium
-
It does not contains calcium salts
B
Correct answer
Explanation
Cartilage has no blood vessels or lymphatics and the nutrition of the cells diffuses through the matrix. This explains the slow healing in cartilages.
-
peritoneum
-
myocardium
-
perichondrium
-
pericardium
C
Correct answer
Explanation
The perichondrium is a layer of dense irregular connective tissues which surrounds the cartilage of developing bones. It consists of two separate layers: an outer fibrous layer and inner chondrogenic layer. The fibrous layer contains fibroblasts, which produce collagenous fibres.
-
muscular system
-
skeletal system
-
nervous system
-
all of the above
-
bones of vertebrates
-
harmones
-
kidney
-
none of these
A
Correct answer
Explanation
Osteology is the scientific study of bones (from Greek 'osteon' meaning bone and 'logia' meaning study). It focuses on the structure, function, and development of the skeletal system in vertebrates. Hormones (misspelled as 'harmones') are studied in endocrinology, and kidneys are the focus of nephrology.
C
Correct answer
Explanation
There are 206 bones in an adult human body.
