Parkinson's disease (characterized by tremors and progressive rigidity of limbs) is caused by degeneration of brain neurons that are involved in movement control and make use of neurotransmitter

Damage to thymus in a child may lead to

• a reduction in haemoglobin content of blood

• a reduction in stem cell production

• loss of antibody mediated immunity

• loss of cell mediated immunity

Gonadotropin releasing hormone is transferred to anterior pituitary by

• axons of neurosecretory cells

• nuclei of hypothalamus

When kidney of a person is damaged, he/she invariably suffers from anaemia because

• RBCs pass through the glomerulus

• sufficient erythropoietin is not produced

• haemoglobin is not synthesised sufficiently

• iron and vitamin B₁₂ are not able to bind to haemoglobin
