What are two aways the hypothalamus sends mesasge to the pituitary glands?
for the anterior pituitary gland it is through the blood capillaries located in the infundibulum and for the posterior pituitary gland it is through the axons in the neurons running through the infundibulum
How is the anterior pituitary connected to the hypothalamus?
The anterior pituitary is connected to the hypothalamus through a network of blood vessels called the hypothalamic-hypophyseal portal system. This system allows hormones produced by the hypothalamus to be transported directly to the anterior pituitary where they can regulate the release of pituitary hormones into the bloodstream.
What connects the hypothalamus to the pituitary gland?
the infundibulum connects the hypothalamus to the pituitary gland, its like a stem. for the posterior lobe (neurohypophysis) is linked by neurons while the anterior lobe is linked by a complex network of blood capillaries it's the spinal column
How does the anterior and posterior pituitary differ?
The anterior pituitary produces and secretes its own hormones in response to releasing hormones from the hypothalamus, while the posterior pituitary stores and releases hormones produced by the hypothalamus. The anterior pituitary is derived from glandular tissue, while the posterior pituitary originates from neural tissue.
Where is the posterior pituitary gland located?
The posterior pituitary is located in a portion of the sphenoid bone called the sella turcica. It is attached to the anterior pituitary gland by the pars intermedia which is a thin layer of endocrine tissue. The posterior pituitary is actually just an extension of the neural tissue that composes the hypothalamus.
Are the adrenal glands divided in to the anterior lobe and posterior lobe?
No it's not! it's the Pituitary Glands that divided the anterior and posterior lobes and thats because it's connected to the hypothalamus!!!!!!
What body system is responsible for thermoregulation?
which body systems are responsible for maintenance of body temperature
What glands and organs release hormones in the female reproductive system?
These are the hormone glands of the endocrine system:OvaryTestesPancreasAdrenalThymusParathyroidThyroidPituitary (Posterior and anterior)HypothalamusPineal
What are the two lobes of the pituitary gland?
The pituitary gland is connected to the hypothalamus by a small stalk. The interaction between the nervous system and endocrine is evident in this hypothalamus-pitutary complex. The pituitary gland produces and stores hormones. The hypothalamus simulate the release of hormones by the pituitary gland by way of nerves.The pituitary gland consist of two lobes. The posterior lobe stores and releases hormones, such as ADH and oxytocin. The anterior lobe of the pituitary gland produces its own hormone. It is richly supplied with nerves from the hypothalamus.
Can the hypothalamus function without the pituitary?
No, because the hypothalamus manufactures the hormones for the posterior pituitary gland and it sends the instructions for the anterior pituitary gland to produce hormones.
Is the hypothalamus is a gland or not?
The parts that traditionally comprise the hypothalamus are not usually considered as a gland. However, a part of the pituitary gland -- which is a type of gland called an endocrine gland-- is actually just an extension of part of the hypothalamus. So technically, it'd be perfectly reasonable to say that that part of the hypothalamus is also part of an endocrine gland.Glands come in two types: endocrine and exocrine. Endocrine glands secrete chemicals into the bloodstream, whereas exocrine glands secrete chemicals and fluids out of the body.The pituitary gland (also called the hypophysis) is one of the body's major endocrine glands. In fact, it is considered the "master gland" of the endocrine system. The pituitary gland can be divided into parts; two major parts are called the anterior pituitary gland and the posterior pituitary gland. "Anterior" means that part is towards the front of the gland; "posterior" means it is towards the back.Both parts of the pituitary gland, both anterior and posterior, are endocrine glands. But they have very different structures. The structure of the anterior pituitary is reflected in its other name, adenohypophysis; "adeno-" means glandular and refers to the glandular appearance of the anterior pituitary when viewed under a microscope. In contrast, the posterior pituitary is also called the neurohypophysis; "neuro-" refers to the fact that the posterior pituitary resembles tissue of the nervous system when viewed under a microscope.The two major pieces of the pituitary gland have different microscopic appearances because they come from different areas of the body. The anterior pituitary actually develops from an outpouching of the roof of the mouth early in development. In contrast, the posterior pituitary comes from the gradual extension of the hypothalamus, which lies directly on top of the pituitary gland.During development, nerve cells (called neurons) of the hypothalamus send long projections (called axons) to form the posterior pituitary. Once they reach the right spot, they set up shop next to a blood vessel. There they organize themselves so that the ends of their projections (called axon terminals) sit right next to the blood vessel wall. These terminals contain little sacs of hormones that get released into the bloodstream whenever the nerve cell is excited.So yes, it's definitely fair to consider at least a part of the hypothalamus as an endocrine gland.
What gland contains the anterior pituitary?
The anterior pituitary is controlled by the hypothalamus, which releases hormones that stimulate the anterior pituitary to release its own hormones. The anterior pituitary itself is not contained within a particular gland, but is connected to the hypothalamus via the pituitary stalk.
