Experiment No. 5
Gross Examination of a hemorrhagic event in the basal ganglia
The large hemorrhage in this adult brain arose in the basal ganglia region of a patient with hypertension. This is one cause for a "stroke".
Experiment # 6
Gross examination of Atrophy and compensatory hypertrophy in kidneys
There is one large-sized kidney with a granular surface and a few scattered, shallow cortical scars. The other kidney shows atrophy because of a narrowed renal artery, most often from atherosclerosis. Such a situation can lead to hypertension.
Experiment # 7
Gross examination of atrophied and hyperplastic pair of adrenals
The pair of adrenals in the center are normal. Those at the top come from a patient with adrenal atrophy (with either Addison's disease or long-term corticosteroid therapy). The adrenals at the bottom represent bilateral cortical hyperplasia. This could be due to a pituitary adenoma secreting ACTH (Cushing's disease), or Cushing's syndrome from Elevated ACTH production.
