WHERE SCIENCE INTERSECTS INNOVATIONTM, Hematoxylin & Eosin Stain: Pineal Gland Tissue Slides (Adult Normal) [NBP2-77770] - Tissue: Human Brain (Pineal Gland), Pathology: Normal. In a paper published in 1940, Le Gros Clark investigated the neural and vascular connections of the pineal gland in the brain of the rhesus monkey and humans.

If the pineal gland is not able to produce sufficient amounts of melatonin, a person could experience insomnia, anxiety, low thyroid hormone production (hypothyroidism), menopause symptoms, or intestinal hyperactivity.

Label pinealocytes and astrocytes. Journal of Anatomy, 74 (4), 471-492. The conical-shaped pineal gland, or epiphysis cerebri, is attached by the pineal stalk to the roof of the diencephalon of the brain, from which it develops.
A chorioidal vessel extends into the straight sinus and this vessel has recurrent twigs descending into the apex of the pineal gland. Small dark nuclei belong to the astrocytes found in the pineal gland. Product What do the pinealocytes produce? From this research, Le Gros Clark (1940) concluded (p 490-491) that the pineal gland of the rhesus monkey contains a central core of neuropil containing a great number of large ganglion cells with branching processes.
The main secretory product of pinealocytes is melatonin, which regulates light-dark cycles (circadian rhythms).
The tissue was cut at 30 and 150 µ and stained with haemotoxylin and eosin.
In fact, less than 1 percent of brain tumors occur in the pineal gland, but 3 to 8 percent of brain tumors in children are found here. The central core is perfused by a rich capillary plexus. Corpora arenacea, or brain sand, are commonly found in the pineal gland. Did u try to use external powers for studying? Pineal gland anatomical location illustration. Because the pineal is a midline structure, these radio-opaque corpora arenacea are often used as indicators of midline deflection of the brain resulting from pathological conditions. Normal sizes have been described in the radiology literature up to 14 mm 9. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads.
