The pituitary gland or hypophysis is derived from two embryologically-distinct tissues. As such, it is composed of both neural and glandular tissue. Both tissues produce hormones that affect a large number of physiological processes.

What tissues make up the pituitary gland?
The pituitary gland or hypophysis is derived from two embryologically-distinct tissues. As such, it is composed of both neural and glandular tissue. Both tissues produce hormones that affect a large number of physiological processes.
Are endocrine glands connective tissue?
CONNECTIVE TISSUE, derived from mesoderm, provides the organizational pattern for endocrine cells of testicular Leydig cells and ovarian stromal cells.
What tissue does the pituitary gland target?
| Endocrine gland/ source of hormone | Hormone | Target organ or tissue |
|---|---|---|
| Anterior pituitary (adenohypophysis) | TSH (thyroid stimulating hormone) | Thyroid gland |
| Prolactin | Mammary gland | |
| Posterior pituitary (neurohypophysis) | ADH (antidiuretic hormone) | Kidney tubules Smooth muscle in arterioles |
| Oxytocin | Uterine smooth muscle Mammary gland |
Which tissue type makes up endocrine glands?
Answer is EPITHELIAL tissue.
What is the histology of the posterior pituitary gland?
Posterior Pituitary. It contains non-myelinated axons which are the neurosecretory cells. The cell bodies of these cells are located in the hypothalamus. It only secretes two hormones: Antidiuretic hormone (ADH) which acts on the kidney, and oxytocin, which acts on the uterus.
What Colour is the pituitary gland?
Glands with light-brown color and which exhibit spongy property are selected for extract preparation. The active principle of pituitary gland is GTH, which is glycoprotein in nature and extremely sensitive to temperature denaturation.
Is pituitary gland endocrine or exocrine?
The pituitary gland is sometimes called the “master” gland of the endocrine system because it controls the functions of many of the other endocrine glands. The pituitary gland is no larger than a pea, and is located at the base of the brain.
Is pituitary endocrine or exocrine?
How the endocrine glands are classified. Discrete Endocrine Glands – these include the pituitary (hypophysis), thyroid, parathyroid, adrenal and pineal glands. Endocrine component of Glands with both an Endocrine and an Exocrine Function. These include the kidney, pancreas and gonads.
What are the 7 hormones of the anterior pituitary gland?
Anterior pituitary
- Adrenocorticotrophic hormone (ACTH)
- Thyroid-stimulating hormone (TSH)
- Luteinising hormone (LH)
- Follicle-stimulating hormone (FSH)
- Prolactin (PRL)
- Growth hormone (GH)
- Melanocyte-stimulating hormone (MSH)
What are the 8 hormones produced by the pituitary gland?
The major hormones produced by the pituitary gland are:
- ACTH: Adrenocorticotrophic hormone.
- FSH: Follicle-stimulating hormone.
- LH: Luteinizing hormone.
- GH: Growth hormone.
- PRL: Prolactin.
- TSH: Thyroid-stimulating hormone.
What is the histology of the anterior pituitary?
The anterior pituitary (adenohypophysis) is composed of two histologically and functionally distinct regions: the pars distalis and the pars intermedia. Brain, rat. The three major regions of the pituitary gland are labeled here: the pars distalis (D, blue), pars intermedia (I, green), and pars nervosa (N, red).
