0%
a) Tetany
0%
b) Muscular dystrophy
0%
c) Myasthenia gravis
0%
d) Botulism
Explanation
Tetany: A condition that is due usually to low blood calcium (hypocalcemia) and is characterized by spasms of the hands and feet, cramps, spasm of the voice box (larynx), and overactive neurological reflexes. Tetany is generally considered to result from very low calcium levels in the blood. Muscular dystrophy is a group of diseases that cause progressive weakness and loss of muscle mass.In muscular dystrophy, abnormal genes (mutations) interfere with the production of proteins needed to form healthy muscle.These mutations are also called germline mutations because they are present in the parent's egg or sperm cells, which are also called germ cells. Myasthenia gravis is a chronic autoimmune, neuromuscular disease that causes weakness in the skeletal muscles. Myasthenia gravis is caused by an error in the transmission of nerve impulses to muscles. Botulism is a rare but serious illness caused by toxins that produce skeletal muscle paralysis. This paralysis affects muscles that help you breathe and move. Answer : (b)

Explanation
sesamoid bone is a bone embedded within a tendon or a muscle. These bones form in response to strain, or can be present as a normal variant. The kneecap is the largest sesamoid bone in the body.

c) Each rib is a flat thin bone and all the ribs are connected dorsally to the thoracic vertebrae and ventrally to the sternum.
0%
d) There are seven pairs of vertebrosternal, three pairs of vertebrochondral and two pairs of vertebral ribs.
Explanation
• Vertebrosternal ribs are true ribs, dorsally they are attached to the thoracic vertebrae and ventrally connected to the sternum with the help of hyaline cartilage. First seven pairs of ribs are called true ribs. • 8th, 9th and 10th pairs of ribs do not articulate directly with the sternum but join the seventh ribs with the help of hyaline cartilage. These are vertebrochondral or false ribs. • Last 2 pairs (11 & 12) of ribs are not connected ventrally and are therefore, called floating ribs. • Only first seven pairs of ribs are ventrally connected to the sternum. Answer : (d)
