Susan M. Webb, María-José Barahona, in Encyclopedia of Endocrine Diseases, Pineal Parenchymal Tumors. Pineocytomas require only local radiotherapy to the tumor (54 Gy). In pinealoblastomas, a high probability of spinal seeding should lead to craniospinal radiotherapy, since they are radiosensitive (25 to 30 Gy on the neuroaxis with a pineal boost of 40 Gy aimed at more effective Pineal Gland. The pineal gland (also called the pineal body, epiphysis cerebri, epiphysis, conarium, or the “third eye”) is the only unpaired midline brain structure. It is about the size of a grain of rice (5–8 mm) in humans. The pineal gland lies between the laterally positioned :_Anatomy_and.

Pineal Gland. The pineal gland, which is sometimes referred to as the pineal body or epiphysis (Fig 2), lies towards the back of the roof of the third ventricle of the brain, between the two hemispheres. It is a small pine cone-shaped structure (hence its name) and forms part of the mid-brain called the epithalamus (Marieb and Hoehn, ). Alot of information for the person knowing nothing about the pineal gland and its full potential, the book is more of a generalization of the topic and not a constructive guideline of what most people probably expect on how to open your third eye. But still by far A Great Little Book and theres only like 3 or 4 blank pages even at the $5 price

Some dismiss the power of the imagination as being unimportant, having no relevance in the physical world, when indeed the opposite is true.

The pineal gland is a small, pinecone-shaped gland of the endocrine system.A structure of the diencephalon of the brain, the pineal gland produces the hormone nin influences sexual development and sleep-wake cycles. The pineal gland is composed of cells called pinealocytes and cells of the nervous system called glial pineal gland connects the endocrine system with the   Chondrichthyes cartilaginous fishes • Acanthodii {extinct} Sarcopterygii lobe-finned fishes, tetrapods Actinopterygii ray-finned fishes Classes: Jawed vertebrates An alternative view of the phylogeny of fishes • Chondrichthyes are not ancestral to bony fishes based on DNA instead of morphology Arnason et al.

Sharks with teeth adapted for shearing and sawing are aided in biting by body motions that include rotation of the whole body, twisting movements of the head, and rapid vibrations of the :// The pineal gland is about inches long and weighs grams.

The adrenergic nerves entering the pineal gland regulate its functions. The pineal gland is composed of pinealocytes and supporting cells that resemble the astrocytes present in the brain.

Some lower vertebrates have a well-developed eye-like structure that acts as a light ://   Like any endocrine gland, the pineal gland secretes hormones into the bloodstream. The hormone that is produced by the pineal gland is known as melatonin.

The role of melatonin is to regulate a person's sleep-wake cycle, and this is why some people with insomnia or other sleep problems take melatonin supplements to achieve better ://   Some Eastern religions, psychics and metaphysicians consider the pineal gland the seat of higher consciousness and clairvoyance.

It is pea-sized (1/3 rd of an inch) lying deep at the center of the brain in the epithalamus. With a reddish-gray color, it is primarily made up of pineal cells and neural support ://   Racial differences have been noted in the rate of pineal calcification as seen in plain skull radiographs.

In Caucasians, calcified pineal is visualized in about 50% of adult skull radiographs after the age of 40 years (Wurtman et al, ); other scholars argue that Caucasians, in general, may have rates of pineal gland calcification as high as ­% (King, ).

Some scientists such as Dr. Rick Strassman believe the pineal gland releases neurochemicals that enhance altered states of consciousness. This would be quite plausible, considering that esoterically, activation of the pineal gland is said to create a deep connection with our higher selves—which goes by many names including that of the In providing a sound phylogenetic framework from leading authorities in the field, this book is an indispensable reference for a broad range of biologists, especially students of fish behavior, anatomy, physiology, molecular biology, genetics and ecology--in fact, anyone who wishes to interpret their work on fishes in an evolutionary :// The pineal gland — a tiny pine cone–shaped organ in the center of the brain — has been a mystery for years.
