What are two divisions of the pituitary gland?
Adenohypophysis and neurohypophysis
How is the relationship between adenohypophysis and neurohypophysis different?
The adenohypophysis, also known as the anterior pituitary gland, produces and secretes its own hormones under the control of releasing hormones from the hypothalamus. In contrast, the neurohypophysis, or posterior pituitary gland, stores and releases hormones produced by the hypothalamus, including oxytocin and vasopressin, which are transported down axons from the hypothalamus.
What are the two parts of the pituitary gland?
The parts of the pituitary gland are the adenohypophysis (anterior) gland and the neurohypophysis (posterior)
What is rathke's pouch?
Rathke's pouch is an upgrowth from the roof of the embryo stomodium that contributes to the adenohypophysis of the pituitary or hypophysis. The pouch contains ectoderm as it is located cranial to the buccopharyngeal (oropharyngeal or oral) membrane. The neurohypophysis is from a simultaneous downgrowth from the developing diencephalon.
What gland is also called the neurohypophysis?
An adenohypophysis is the anterior lobe of the pituitary gland, which produces and secretes peptide hormones which regulate many physiological processes.
How many lobes make up the pituitary gland?
The pituitary gland has three lobes: The anterior, intermediate, and posterior
What is thehormone produced by an endocrine gland located below the brain?
The endocrine gland below the brain is the pituitary gland. It is split into anterior (adenohypophysis) and posterior (neurohypophysis) sections. They differ in the hormones they produce. Adenohypophysis: ACTH (adrenocorticotropic hormone), TSH (thyroid stimulating hormone), FSH (follicle stimulating hormone), LH (luteinizing hormone), GH (growth hormone), Prolactin Neurohypophysis: Oxytocin, ADH (antidiuretic hormone, aka vasopressin)
How does AIA identify anterior pituitary?
AIA (anterior internal artery) identifies the anterior pituitary gland by supplying blood to it. This artery branches from the internal carotid artery and courses through the pituitary gland, providing oxygenated blood to its anterior portion.
Are the hypothalamus and the neurohypophysis the same?
The hypothalamus and the neurohypophysis are not the same. They are separate parts of the brin.
What are the two sections of the pituitary?
The pituitary gland is divided into two sections: the anterior pituitary (adenohypophysis) and the posterior pituitary (neurohypophysis). The anterior pituitary produces and releases hormones that regulate various physiological processes, while the posterior pituitary stores and releases hormones produced by the hypothalamus.
What is an other name for anterior lobe of the pituitary gland?
It is also called the neurohypophysis. ADH and oxytocin are produced in the hypothalamus. These are stored in the posterior pituitary. No hormones are actually produced in the posterior pituitary, they are only stored.
Where is the pituitary gland located in the human body?
Anatomically, the pitutary gland is formed of two parts: Adenohypophysis and Neurohypophysis. The adenohypophysis develops as an outgrowth of pharynx, called Rathke's pouch and is again divided in to three parts -- pars distalis, the pars intermedia and the pars tuberalis. Pars distalis and pars tuberalis together are known and ANTERIOR LOBE of pitutary gland.
