The adenohypophysis is a part of the pituitary gland, which is located at the base of the brain. It is also known as the anterior pituitary.
The adenohypophysis, also known as the anterior pituitary, is a small gland located at the base of the brain. It is a part of the pituitary gland, which is often referred to as the "master gland" because it regulates the functions of several other endocrine glands in the body.
To locate the adenohypophysis in terms of its position in the brain, follow these steps:
1. Identify the brain: The brain is located within the skull and is divided into several regions, including the forebrain, midbrain, and hindbrain.
2. Locate the pituitary gland: The pituitary gland is positioned at the base of the brain, just below and behind the hypothalamus. It is housed in a small bony cavity called the sella turcica, which is located within the sphenoid bone.
3. Differentiate between the posterior and anterior pituitary: The pituitary gland is divided into two parts - the posterior pituitary and the anterior pituitary. The posterior pituitary, also known as the neurohypophysis, is a glandular extension of the hypothalamus and is composed of nerve fibers. It is located behind the anterior pituitary.
4. Identify the adenohypophysis (anterior pituitary): The adenohypophysis is the front portion of the pituitary gland and accounts for approximately 80% of its total weight. It is made up of glandular tissue and secretes various hormones that regulate bodily functions such as growth, reproduction, and metabolism.
Therefore, to locate the adenohypophysis, you would first locate the brain, then find the pituitary gland at the base of the brain, and finally identify the anterior portion of the pituitary gland, which is the adenohypophysis.
