Document Summary
Pathological basis of disease gastrointestinal tract and neurological histology. Lieberkuhn, which consists of: absorptive cells, goblet cells, regenerative cells, enteroendocrine cells: lamina propria > muscularis > submucosa > circular muscle of muscular externa, the colon has columnar cells on apical surface. Pancreas which histological areas secrete which products: pancreatic acinus > produces digestive enzymes that are released in the liver, exocrine function, islets of langerhans > produce insulin, endocrine function. Neurological pathology normal vascular responses in brain, types of haematoma & aneurysm characteristics and locations. There needs to be a constant cerebral blood flow (cbf), as the brain doesn"t really store any energy and it has such a high demand. Vessels in the brain are capable of autoregulation > capacity of the vessels to change their diameter, to regulate the blood being sent to certain areas (that need it the most). Haematoma > a solid swelling of clotted blood within the tissues.
