Adhering together to form plugs when exposed to collagen

Liberating high conceintrations of calcium

Inhibiting fibrinolysis by blocking the conversion of plasminogen to plasmin

Both A and B

Disease of the extra pyramidal motor system in parkinsonism causes

Tremor which is more obvious when the patient is performing skilled movements

Muscle paralysis

Increased involuntary facial movements during speech

An unusual gait with small fast regular steps

Hemisection of the spinal cord at C7 on the right side would cause

Greater loss of pain sensation in the right foot than in the left foot

Greater loss of conscious proprioception in the right than in the leftleg

Loss of micturition reflex

Respiratory failure

In which condition does the lung compliance increase

Chronic obstructive lung disease

Tuberculosis

Respiratory distress syndrome

Abscess

What is the significance of residual volume

No significance

To make continuous exchange of gases available and maintain concentration of oxygen and carbon dioxide

To prevent lung collapse

To aid breathing

Which is the false statement

Peripheral chemoreceptor are located in carotid and aortic bodies

Central chemoreceptors are located in pons

Peripheral chemoreceptors respond to changes in partial pressure of oxygen and carbon dioxide

Central chemoreceptors respond to changes in H+ ion concentration

Antidiuretic hormone

Tends to raise the osmolality of plasma rise

Increases the permeability of the cells in the loop of Henle to water

Secretion is little affected by changes in plasma osmolality of less than 10 percent

Secretion increases when plasma volume falls but osmolality is unchanged

Growth hormone ( choose the false statement)

Secretion is under hypothalamic control

Levels in blood are higher in children than in adults

Secretion surges during sleep

Stimulates liver to secrete somatomedins which regulate bone and cartilage growth

Thyroid stimulating hormone secretion is increased

Pain due to poor coronary blood flow (angina) may NOT be relieved by

Cutting the sympathetic nerve trunks supplying the heart

Correcting anemia if present

Providing the patient with a cold environment
