What part of the pituitary gland contains secretory cells?
The anterior pituitary, also known as adenohypophysis, is a classic endocrine gland in that it is composed of secretory cells of epithelial origin supported by connective tissue rich in blood and lymphatic capillaries.
What are the 5 hormones secreted by pituitary gland?
The major hormones produced by the pituitary gland are:
- ACTH: Adrenocorticotrophic hormone.
- FSH: Follicle-stimulating hormone.
- LH: Luteinizing hormone.
- GH: Growth hormone.
- PRL: Prolactin.
- TSH: Thyroid-stimulating hormone.
What gland regulates the secretory activity of the pituitary gland?
The pituitary gland has two main parts, the anterior pituitary gland and the posterior pituitary gland. The gland is attached to a part of the brain (the hypothalamus) that controls its activity.
What activates the pituitary gland?
In some cases, the hypothalamus signals the pituitary gland to stimulate or inhibit hormone production. Essentially, the pituitary acts after the hypothalamus prompts it.
What does the pituitary gland secrete?
There are four hormones secreted by the anterior pituitary gland that control the functions of other endocrine glands. These hormones include thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), and luteinizing hormones (LH).
What part of the pituitary gland contains secretory cells quizlet?
infundibulum. Region of the hypophysis that contains secretory endocrine cells derived from the oral ectoderm. Region of the hypophysis that releases hormones stored in neurosecretory bodies in axon terminals.
Does the hypothalamus regulate the secretory activity of the pituitary gland?
The hypothalamus links the nervous and endocrine systems by way of the pituitary gland. Its function is to secrete releasing hormones and inhibiting hormones that stimulate or inhibit (like their names imply) production of hormones in the anterior pituitary.
What are the two modes through which hypothalamus cause the release of hormone by pituitary gland?
There are two sets of nerve cells in the hypothalamus that produce hormones. One set sends the hormones they produce down through the pituitary stalk to the posterior lobe of the pituitary gland where these hormones are released directly into the bloodstream. These hormones are anti-diuretic hormone and oxytocin.
How the hypothalamus controls the pituitary gland?
How is the secretion of pituitary hormones regulated?
Their secretion is regulated, however, by releasing and inhibiting hormones from the hypothalamus. The six anterior pituitary hormones are: growth hormone (GH), thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin (PRL).
Are there glial cells in the pituitary gland?
Pituicytes are the glial cells of the pituitary gland; the nuclei that are visible in sections of posterior pituitary belong to these cells, as well as cells of the vasculature. A third section of the pituitary, the intermediate lobe, is vestigial in man.
What kind of cells are in the anterior pituitary?
The anterior pituitary contains cells that, when viewed under the light microscope, appear as acidophils, basophils, or chromophobes. This slide displays the three cell types of the anterior pituitary under H&E stain. The acidophils appear as cells with pink cytoplasm and dark nuclei.
Is the hypothalamus part of the pituitary gland?
The pituitary gland, or hypophysis, is a collection of different cell types that control the activity of other endocrine organs. It is governed by the hypothalamus, which sends both electrical and hormonal signals to the pituitary, and by feedback regulation (both positive and negative) through the secretions of its target glands.
