neurohypophysis
The posterior pituitary gland is composed of nervous tissue. It stores and releases hormones produced by the hypothalamus, such as oxytocin and vasopressin, into the bloodstream.
The adrenal medulla and the pituitary gland are two endocrine glands that contain a mixture of nervous and epithelial tissues. The adrenal medulla is part of the adrenal glands and is composed of neural tissue, while the pituitary gland is located in the brain and consists of both nervous and glandular tissue.
The portion of the brain that controls the pituitary gland is known as the hypothalamus. The pituitary gland is responsible for all the functions in the body.
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.
I'll use the pituitary gland as an example. Anatomically, the pituitary gland is located at the base of the brain attached to it by a puny little stalk called the infundibulum. In a gross specimen of the brain, it looks as though the pituitary gland is brain tissue, but brain tissue that's organized and separated from the rest of the brain. It turns out that the pituitary gland is really two separate glands smashed together: the anterior pituitary and the posterior pituitary. Embryologically, the anterior pituitary comes from the early roof of the mouth, called Rathke's pouch. The posterior pituitary is a direct extension of the hypothalamus. It's this latter relationship that makes the pituitary gland a real, bona fide part of the nervous system. Another example is the medulla of the adrenal gland, which is an endocrine organ that secretes the hormones adrenaline and noradrenaline. The adrenal medulla comes from the same embryonic tissue that much of the sympathetic nervous system comes from (called the neural crest cells). So the adrenal medulla is really just a modified part of the sympathetic nervous system. Specifically, the medulla is made of specialized postganglionic neurons of the sympathetic nervous system.
Yes, the pituitary gland is composed of both glandular and neural tissue. The anterior pituitary is primarily glandular and produces and releases hormones, while the posterior pituitary is neural tissue that stores and releases hormones produced by the hypothalamus.
The autonomic nervous system is controlled by the brainstem, hypothalamus, and spinal cord. The pituitary gland is controlled by the hypothalamus through the release of specific hormones that regulate pituitary function.
The pituitary gland controls the endocrine system.
Correct, the posterior pituitary gland is mostly composed of nerve tissue, specifically axons and nerve endings. It stores and releases hormones produced by the hypothalamus, but it does not manufacture its own hormones like the anterior pituitary gland does.
Puberty is started by a sudden increase in hormones, released by the Pituitary gland.
It depends on the tissue, but generally speaking, the pituitary gland is responsible for releasing growth hormones.
The hypothalamus is a portion of the brain that controls the pituitary gland, water balance, and body temperature. It plays a crucial role in regulating various bodily functions by sending signals to the pituitary gland to release hormones that control these processes.
