Select the chromosomal disorders from the following diseases affecting humans

I. Haemophilia

II. Down's syndrome

III. Klinefelter's syndrome

IV. Sickle cell anemia

V. Turner's syndrome

VI. Thalessemia

Options:
A All except II, III and V
B All except I and IV
C All except I, IV and VI
D All except I, II and VI

The correct answer is:
All except I, IV and VI

Chromosomal disorders are the diseases/conditions occur due to change in the number of the chromosomes in the individual. Down's syndrome is due to extra 21st chromosome, Turner's syndrome is caused in female due to lack of one of the X chromosome from the 23rd pair of XX. Klinefelter's syndrome is caused due to extra copy of the X chromosome in a male making the 23rd pair as XXY. Haemophilia, sickle cell anemia, thalassemia are disorders occurring due to change in a single gene of the chromosome rather than the whole chromosome undergoing change. These are also called as Mendelian disorders as they generally follow Mendel's laws of inheritance.

Select the correct events that occur during inspiration.

(a) Contraction of diaphragm
(b) Contraction of external intercostal muscles
(c) Pulmonary volume decreases
(d) Intrapulmonary pressure increases

Options:
A (c) and (d)
B (a), (b) and (d)
C only (d)
D (a) and (b)

The correct answer is:
(a) and (b)

Solution:
INSPIRATION: Inspiration is an active process involving the contraction of the muscles. The external intercostal muscles contract, making the ribs move outward, sideward and upward. This increases thoracic volume. Simultaneously the muscles of the diaphragm also contract and the diaphragm becomes a flattened sheet, further increasing the thoracic volume. This decreases intrapleural pressure and the pressure in the lungs. This decrease in the pressure makes the air rush in from the surrounding atmosphere into the lungs. The lungs being elastic expand to accommodate the air rushing in. The air pressure in the lungs becomes equal to the atmospheric pressure. Even though the external intercostal muscles are necessary for breathing the diaphragm is the principal organ of breathing.
