Essentially, blood pressure is monitored by baroreceptors found in the aorta and carotid arteries and regulated by the cardiovascular centre in the medulla of the brain. Baroreceptors continually send impulses to the cardiovascular centre. If blood pressure rises, the rate of impulses being sent to the cardiovascular centre increases. In response to this, the cardiovascular centre reduces heart rate and force of contraction by decreasing sympathetic stimulation and increasing parasympathetic stimulation of the heart. At the same time sympathetic stimulation of blood vessels decreases.

The trachea divides into two bronchi, which enter the lungs. The bronchi divide into secondary and tertiary bronchi and further into smaller branches called bronchioles. The airways are lined with ciliated mucosal epithelium.

Aplastic anaemia is due to loss of haemopoietic tissue in bone marrow and therefore decreased production of red blood cells. This a common side effect of cytotoxic drugs. Effective haemoglobin synthesis and red blood cell production also depends on the action of a growth factor, erythropoietin, produced by the kidneys. In chronic renal failure lack of this growth factor results in anaemia. Replacement therapy is by intravenous or subcutaneous injection of epoetin.

Many of the hormones of the anterior pituitary gland in turn regulate the activity of other endocrine glands and are known as trophic hormones or trophins. This is a large gland in the neck, lying just below the larynx and anterior to the trachea. The thyroid gland produces and secretes thyroid hormone and calcitonin.

Fungal infections are known as mycoses and can be either superficial infections of the skin and nails or systemic infection of the internal organs, particularly the lungs. Both types of infection have become more common since the broad-spectrum antibiotics and an increase in numbers of immunocompromized individuals because of HIV infection and the use of immunosuppression and cancer chemotherapy. Overuse of broad-spectrum antibiotics leads to a reduction in the bodys normal flora (harmless bacteria) that compete with fungi, allowing the fungi to overgrow.

Side effects of MAO-B inhibitors include nausea, dry mouth, dizziness, postural hypotension, insomnia, confusion and hallucinations.

With the advent of the HIV and acquired immunodeficiency syndrome that follows infection with HIV, many new antiviral drugs have been introduced since the end of the about how viruses replicate inside cells and how they affect cell function, then no doubt more antiviral drugs will be developed.

The main distinction is that the newer drugs produce fewer motor side effects. Phenothiazines were developed after it was noticed that the antihistamine, promethazine had a sedative action.
