|---|---|
| pedunculus of pineal body | See: habenula. (05 Mar 2000) |
| pineal | A gland-like structure in the brain which appears to be the major site of melatonin biosynthesis. The exact role of the pineal remain obscure. (27 Sep 1997) |
| pineal body | A small conical midline body attached to the posterior part of the third ventricle and lying between the superior colliculi, below the splenium of the corpus callosum. (12 Dec 1998) |
| pineal cells | Cell's of the corpus pineale or pinealocyte. (05 Mar 2000) |
| pineal cyst | A cyst of the pineal gland; rarely of clinical importance. (05 Mar 2000) |
| pineal eye | A non-image-forming, photoreceptive eye in or near the median line in certain crustacea and lower vertebrates; homologue of pineal gland in higher forms. Synonym: epiphysial eye, parietal eye. (05 Mar 2000) |
| pineal gland | A small, flat gland found within the brain which produces the hormones melatonin and serotonin. (09 Oct 1997) |
| pineal gland calcification | <radiology> Visible on plain skull film (33-76% in adults), seen more frequently on CT, rare in kids less than 6 y.o. (presence suggests neoplasm), usually in the form of a cluster of amorphous, irregular densities, may be solitary, the size of calcification: usually 3-5 mm, if greater than 1 cm, suspect pinealoma, AV malformation, etc. See: physiological intracranial calcifications (12 Dec 1998) |
| pineal habenula | The peduncle or stalk of the pineal gland. See: habenula. (05 Mar 2000) |
| pineal recess | A diverticulum from the posterior part of the third ventricle extending back between the posterior commissure and the habenular commissure. Synonym: recessus pinealis. (05 Mar 2000) |

| brain tumours | Can be malignant or benign and can occur at any age. Primary brain tumours initially form in the brain tissue. Secondary brain tumours are cancers that have spread to the brain tissue (metastasized) from tissue elsewhere in the body. (12 Dec 1998) |
