Exercise 1: The Pituitary Gland obseRvations

A. Please describe in detail the structures and features you observed on the pituitary gland slide.

The Pituitary Gland Slides The Anterior Pituitary Gland was darker than the Posterior Pituitary Gland. In the Anterior Pituitary Gland Slide you can see Chromophobes and Acidophiles. Not super easy to distinguish which is which though. The Posterior Pituitary Gland slide showed Pitulcytes (Neuroglia) as light purple cells and the Herring Bodies are very ligjt pink with a lot of white clear space surrounding.

Data Table 1: Do some research and fill in the data table below. | Hormone | Functions | Adrenocorticotropic hormone (ACTH) | ACTH stimulates the cortex to secrete hormones called glucocorticoids. Like cortisol. Which regulates glucose, protein, and fat metabolism, and response to stress. | Antidiuretic hormone (ADH) | ADH regulates water retention in the kidneys, reduces urine volume, and helps prevent dehydration. Also a brain neurotransmitter. | Follicle stimulating hormone (FSH) | The pituitary secretes FSH. It stimulates the sex hormone estrogen and development of follicles in the ovaries. And Sperm production in the testes. | Growth hormone (GH) | GH promotes mitosis and cellular differentiation. GH does not have specificity like other hormones. | Luteinizing hormone (LH) | LH stimulates ovulation of eggs from the follicles developed by FSH in women. In males LH stimulates the testes to produce testosterone | Melanocyte stimulating hormone (MSH) | Fetal hormone determining the color of skin or hair. | Oxytocin | Released by posterior pituitary to stimulate labor, milk release, possibly involved in ejaculation, sperm transport, sexual affection and mother infant bonding | Prolactin (PRL) | Stimulates milk synthesis. Is also found in testes. | Thyroid stimulating hormone (TSH) | Thyrotropes in pituitary secrets and stimulates growth of

    Essay On Hypothalamus

    • 573 Words

    In vertebrates, the hypothalamus, located at the base if the brain, plays a central role in integrating the endocrine and nervous systems. The hypothalamus receives information from nerves throughout the body and the brain. (Mousa and Mousa, 2003) In response, the hypothalamus initiates endocrine signalling appropriate to environmental conditions. In many vertebrates’ nerve signals from the brain pass information to the hypothalamus about seasonal changes, therefore the hypothalamus regulates the release of reproductive hormones, which are required during breeding seasons. (Campbell and Reece, 2011) The hypothalamus signals travel to the pituitary gland, which is located at the base of the hypothalamus with posterior and anterior parts. The anterior pituitary is an endocrine gland that synthesises and…

    The aim of the female reproductive system is to produce mature oocytes which match with the male spermatocyte to create offspring. Fertilisation most commonly occurs in the fallopian tubes, though this can also occur later in a female’s menstrual cycle if the egg has already moved down into the uterus, though there is a higher chance of miscarriage as the lining of the womb may continue to shed. The external female reproduction features have two functions; to allow insemination and to also protect against infection and injury. These structures include; the labia majora, which contains glands that produce sweat, the labia minora which surrounds the opening of the vagina and urethra, bartholin's glands which are just behind the vaginal…

    The class viewed sheep brains, human models, and demo cats. The class separated into groups and began locating the listed endocrine glands on the human models. There were also human brain models to identify specific glands. Once finished, the major endocrine glands of the sheep brain were viewed. The sheep brain is quite similar to the human brain except for proportion. Although, the orientation of the human brain is superior to inferior whereas the sheep brain is anterior to posterior. The demo cats were very interesting. One of the cats viewed was pregnant. The placenta was obvious. It surrounded each kitten individually. Although the cat and human are very different externally, both have similar internal composition. Majority of the endocrine glands are placed in similar positions. Some endocrine glands are totally different when it comes to placement. For example, the adrenal glands, in the human models, sit on top of the kidneys. Opposed to the cat, the adrenal glands sit to the side of the kidneys. The thymus is anterior to the heart in the demo cat. The thymus is posterior to the heart in the human models. Although different, the studied examples of endocrine glands were all very similar in structure and…
