Development

The pineal gland develops from the upper wall of the second brain bladder, i.e., the intermediate brain. In the lower vertebrates, it is the last among the outgrowths that are leaving near the specified place. They are located in the following order: 1) paraffiz, 2) the outcome of the vascular plexus, 3) a non -parish parietal eye, 4) epiphyse. In the human embryo, vascular growth and pineal gland remains of them. The latter at first is a simple epithelial protrusion, which subsequently surrounds the connective tissue and vessels and gives a large number of secondary outgrowths. The result is a compact body sitting on the leg.


Anatomy

Epiphyse or pineal gland of a person is placed on the upper surface of the brain barrel and lies back, in the furrow of the anterior quadruple. It is a small, slightly flattened body resembling a spruce bump. Its average size: in the sagittal direction - about 9 mm, in the frontal - about 6 mm, the diameter - about 4 mm; Weight - about 0.2 g. The pineal gland is connected by a stalk, which is relaxed on two brain plates; Between them, a slight continuation of the cavity of the 3rd ventricle was made. A bridle or the legs of the pineal gland departs from the upper plate; The lower plate, bending back and thickening, continues in the plate of the four -cholegol. The pineal gland is shrouded in the brain shell and easily breaks off when removing the latter, which must be borne in mind when preparing.

In a number of vertebrates of various classes, pineal glands is absent. This was found in the slope of Torpedo, a crocodile, an armadillo, a seal and some whales.


Histology

In a developed state, the cinema -shaped iron of a person reveals the following structure. The connective tissue covering the surface of the surface gives processes that divide the inside into slices of various sizes made by special cells. Slices are not everywhere tightly diligently dedicated to each other and between them there are gaps of various sizes and shapes, consisting of typical neuroglia with rare compact nuclei and a thick binding of thin fiber, as in the nervous fraction of the pituitary gland. As for the cellular elements of the slices, they are larger formations with a bubble oval core, often polymorphic and cut folds, and a cellular body, often equipped with processes and containing brown pigment grains. These elements are usually considered with glandular cells that give their secret to the blood capillaries, which, however, there are not so many.
