| primary biliary cirrhosis | <gastroenterology> A rare form of liver disease which results in the irreversible destruction of the liver and bile ducts. The cause is unknown, but is thought to be an autoimmune mechanism. (06 Mar 1998) |

| primary brain tumour | <neurology, oncology> May be subdivided into primary brain tumours and the more common, secondary brain tumours. Primary brain tumours (for example astrocytoma, craniopharyngioma, glioma, ependymoma, neuroglioma, oligodendroglioma, glioblastoma multiforme, meningioma, medulloblastoma) arise from the uncontrolled proliferation of cells within the brain. Secondary brain tumours occur from the spread of cancer into the brain from a distant cancerous organ (metastasis). Common symptoms of a brain tumour include headache, nausea, vomiting, seizures, change in mentation, neurologic symptoms and loss of memory. (06 Mar 1998) |
| primary brain vesicle | Each of the three divisions of the early embryonic brain (prosencephalon, mesencephalon, and rhombencephalon). Synonym: encephalic vesicle, primary brain vesicle. (05 Mar 2000) |
| primary bronchus | The main bronchus arising at the tracheal bifurcation and extending into the developing lung of the embryo. (05 Mar 2000) |
| primary butyl alcohol | Propylcarbinol, CH3CH2CH2CH2OH, the butyl alcohol of fermentation; isobutyl alcohol, isopropylcarbinol, 2-methyl-1-propanol, (CH3)2CHCH2OH; narcotic in high concentrations, secondary butyl alcohol, ethylmethylcarbinol, 2-butanol, CH3CH2CH(CH3)OH; and (05 Mar 2000) |

| primary cell culture | <cell culture> Of animal cells, the cells taken from a tissue source and their progeny grown in culture before subdivision and transfer to a sub culture. (18 Nov 1997) |
| primary cell wall | <plant biology> A plant cell wall that is still able to expand, permitting cell growth. Growth is normally prevented when a secondary wall has formed. Primary cell walls contain more pectin than secondary walls and no lignin is present until a secondary wall has formed on top of them. (06 Mar 1998) |
| primary cementum | Cementum that has no cementocytes; may cover the entire root of the tooth, but often is missing on the apical third of the root. (05 Mar 2000) |
