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
acetylcholine
norepinephrine
dopamine
GABA
C.
dopamine
A dopamine deficiency is due to low level of dopamine in the body. It leads to a problem with the receptors in the brain and develops into Parkinson's disease or depression.
Acetylcholine is a major neurotransmitter responsible for memory and learning. It can lead to diseases such as dementia and Alzheimer's.
Norepinephrine promotes arousal and alertness. Increased levels of norepinephrine leads to excessive activity of sympathetic nervous system, and it can further lead to obesity, metabolic syndrome and high blood pressure.
GABA or Gamma- Amino Butyric Acid deficiency can lead to depression, anxiety, insomnia etc.
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
Gonadotropin releasing hormone is transferred to anterior pituitary by
left coronary artery
hypophysial portal veins
axons of neurosecretory cells
nuclei of hypothalamus
Blood calcium level can be increased by the administration of
glucagon
thyroxine
parathormone
caleitonin
Moulting hormone is secreted by
corpora cardiacum
prothoracic gland
corpora allata
neurosecretory hormone
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
