What is the function of the infundibulum?
connects the posterior pituitary and hypothalamus
Is the hypothalamic-hypophyseal tract partly contained in the infundibulum?
yeah the infundibulum connects the hypothalamus and the neurohypophysis
To what specific part of the brain does the infundibulum connect to the pituitary gland?
The infundibulum connects the hypothalamus of the brain to the pituitary gland.
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
What is the anotomical relationship between the hypothalamus and posterior pituitary?
They are attached by infundibulum , posterior pituitary is actually continuation of hypothalamus .
Which endocrine gland that is composed of an anterior and posterior lobes hangs from the infundibulum below the hypothalamus?
The pituitary gland hangs from a stalk from the inferior surface of the hypothalamus of the brain.
How is the anterior pituitary connected to the hypothalamus?
The hypothalamus is connected to the pituitary gland in two ways. One is via the hypophyseal portal system, which is a system of blood vessels that connects parts of the hypothalamus to the anterior pituitary gland. The hypothalamus secretes hormones into this portal system and the hormones act on the anterior pituitary to trigger the synthesis/secretion of pituitary hormones. The other is a direct anatomical connection between the hypothalamus and the posterior pituitary gland. In fact, the posterior pituitary gland is actually just an extension of the hypothalamus. When we talk about hormones released by the posterior pituitary, we're actually talking about hormones made and released by the hypothalamus. It just so happens that with the naked eye, it looks like the anterior and posterior pituitary are all part of one big pituitary gland. But microscopically, functionally and anatomically, the pituitary gland is just an outgrowth of the hypothalamus.
What is the infundibulum?
The infundibulum is a funnel-shaped structure at the top of the chickens oviduct. When a follicle ruptures and drops an ovum it lands in the infundibulum. This happens shortly after ovulation. The infundibulum captures the mature ovum and while in the infundibulum, the egg is fertilized if sperm is available. It is while in the infundibulum that the very first layer of albumen is deposited. The infundibulum holds the roosters sperm sac which can supply the germinal disk for each ovum for as much as 10 to 14 days.
How does the TRH travel from the hypothalamus to the pituaitary gland?
The hypothalamus sends releasing hormones to the pituitary gland down through a salk of tissue called the infundibulum. It tells it which hormones to make and when to make them.
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
What organ connects the endocrine and nervous systems?
hypothalamus
What connects the endocrine system and the nervous system?
hypothalamus
