Slide Pituitary gland Masson cross Webscope Imagescope orientation.
Slide Pituitary gland Masson sagittal Webscope Imagescope orientation. Study the pars distalis anterior lobe in the slide stained with Masson trichrome pars distalis Webscope ImageScope. The cells are arranged in irregular clusters or cords and are distinguishable by their staining as either acidophils, basophils, or chromophobes.
Theacidophils stain red or orange-red, while the basophils stain various shades of blue or blue-gray. To a lesser extent, corticotropes also produce other signaling factors derived from POMC such as lipotropins involved in lipid metabolismendorphins endogenous opioids that reduce pain perceptionand melanocyte stimulating hormone MSH.
You will only be required to distinguish acidophils from basophils. Your best strategy is first to identify acidophils, which are more distinctively stained, and then the remaining cells are almost entirely basophils. The cells are not uniformly distributed throughout the pars distalis, but instead there are areas where acidophils predominate, other areas where basophils are more numerous, while still other regions may show a more even mixture of acidophils and basophils.
INDO Note the abundant sinusoidal capillaries often filled with red blood cells sinusoidal capillaries Webscope ImageScope that lie between the cell cords or clusters. You can appreciate how readily the hormones secreted from the cells can reach the blood. Since collagen stains bright blue with the Masson trichrome method, you can see the delicate connective tissue partitions between cords and around blood vessels.
Slide Pituitary gland Masson sagittal Webscope Imagescope. The pars nervosa looks like brain tissue, which it is.
It is an extension of the brain, composed primarily of nerve fibers axons which originate from nerve cell bodies in the hypothalamus and pass to the pars nervosa by way of the hypothalamo-hypophyseal tract and the infundibular stalk. These nerve fibers carry oxytocin and antidiuretic hormone ADH, vasopressin to nerve endings, from which they are released into nearby capillaries upon neural stimulation from the hypothalamus.
There is not much to see in the posterior lobe in these histological sections.Cell id info
Since there are no neuron cell bodies in this structure, most of the prominent nuclei belong to pituicyteswhich are the characteristic glial cells of the pars nervosa. You will also see the nuclei of blood vessel endothelial cellsand fibroblasts which are in the connective tissue around these vessels. Slide Pituitary gland monkey Masson cross Webscope Imagescope.
The pars intermedia is very poorly developed in the human pituitary, but is prominent in the pituitaries of most other mammals. For example, in the monkey pituitary, you will see the pars intermedia as a prominent layer several cells thick, lying between the pars distalis and pars nervosa.
Cells of the pars intermedia also produce POMC pro-opiomelanocortinwhich in these cells is processed primarily into endorphins and MSH melanocyte stimulating hormone. Although most of the human axial sections in your sets do not show the human pars intermedia very well, the sagittal sections in some of the sets show some indication of it. This slide shows the hypophyseal portal blood vessels Webscope ImageScope that carry releasing hormones from the hypothalamus to regulate the release of hormones from the pars distalis of the pituitary.
Look for these prominent blood vessels in portions of the pars distalis that extend up around the infundibular stalk. In many of these slides the sinusoidal capillaries Webscope ImageScope lying between cords of pituitary cells throughout the anterior pituitary are shown particularly well. Scan over the slide, reviewing other features you saw in slides and e.Lavarniya mishra bella agency
You will not be required to identify these cell types in electron micrographs, but should note that the cells differ in size, shape and in the number, size and distribution of their secretory granules small black structures in the cytoplasm.
When the content of a secretory granule is released from the cells, the hormones diffuse to nearby capillaries. The endothelium of these capillaries is very thin and, as with most endocrine organs, contains fenestrations not seen clearly in this micrograph.
Two gonadotropes occupy most of the lower half of the figure.Biology, Other Sciences. Played 64 times. Print Share Edit Delete.

Ductless gland that secretes one or more hormones into the bloodstream. A condition caused by a failure of the adrenal cortex to secrete sufficient cortisol and aldosterone. Cushing's syndrome. Addison's disease. Hormone released by the parathyroid glands that regulates blood calcium levels.
External portion of the adrenal gland; its primary hormones, aldosterone and cortisol, influence inflammation, metabolism, interstitial fluid volume, and other functions. Disease caused by too much cortisol from excessive production of glucose from glycogen and protein, and retention of too much salt; causes fat accumulation in certain areas of the body including the face, abdomen, and back of the neck.
A hormone secreted by the pancreas that enhances the uptake of glucose by cells, thus lowering blood glucose levels. A type of cell in the hypothalamus that essentially functions as both a nerve cell and an endocrine cell because it generates nerve impulses and releases hormone into blood vessels. A chemical messenger molecule secreted by an endocrine gland or cell into the bloodstream that has effects on specific target cells throughout the body.
An intracellular messenger molecule generated by the binding of a chemical messenger hormone or neurotransmitter to a plasma membrane receptor on a cell's outer surface; mediates intracellular responses to an extra-cellular first messenger.
Body system that includes all of the hormone-secreting organs and glands; involved in coordination and control of body activities. Organ located behind the stomach; secretes digestive enzymes and bicarbonate into the small intestine and the hormones insulin and glucagon into the bloodstream. Substance produced by basophils and mast cells that causes vasodilation and increases vascular permeability. A hormone secreted by the pineal gland that seems to synchronize our body's daily rhythms and may induce sleep.
Glucocorticoid produced by the adrenal cortex, also called hydrocortisone, that during fasting assists in maintaining blood glucose levels by promoting the utilization of fats by increasing the breakdown of protein to amino acids in muscle.
Region of the brain forming the floor of the third ventricle; helps regulate the body's internal environment by secreting releasing factors that affect the secretion of hormones of the anterior pituitary. Hormone producing glands located atop the kidneys.Production by the adrenal gland is insignificant compared with sex hormone release from the gonads during late puberty.
