Multipotent stem cells arepartially differentiated, so that they form a limited number of tissue types. Multipotent cells produce only cells of a closely related family of cells (e.g., hematopoietic stem cells differentiate into red blood cells, white blood cells, platelets). What is hematopoietic...
What do gland cells produce? What is squamous metaplasia of the bladder? Where are Langerhans cells found? What are gland cells? What is the function of chorionic villi? Where are glial cells located? What is the function of the fallopian tubes? What is ...
The parathyroid glands are located behind the thyroid gland in the neck. There are four parathyroid glands in the body, and they produce parathyroid hormone (PTH). PTH regulates the body's calcium and phosphorus levels.
These cells break down the calcified matrix of the bone tissue. Answer and Explanation: The correct answer is b. Parathyroid hormone (PTH). The parathyroid hormone (PTH) promotes an increase in the activity of osteoclasts. PTH increases...Become...
their primary function. For example, TSH is released by the anterior pituitary to stimulate the thyroid gland; gut hormone peptides (glucagon, OXM) act on intestinal epithelial cells; growth hormone can act on any cell that expresses its receptor, and some adult liver cells produce erythropoietin...
The immune system mistakes the parathyroid gland cells for foreign bodies and attacks them. Parathyroid glands stop the production of PTH because of this process. Hereditary hypoparathyroidism: The person may be born with a defective parathyroid gland that does not produce any hormone or some peop...
The thyroid gland also produces calcitonin, which opposes the effects of PTH and acts to lower blood calcium levels. Calcitonin lowers blood calcium level by increasing the amount of calcium excreted in the urine and suppressing the activity of the osteoclasts, cells that degrade bone. Learn more...
Both the osteocyte and periosteal cell layer are assuming greater importance in the process of maintaining skeletal integrity as our knowledge of these cells expand, as well being a target for pharmacological agents to reduce fracture especially in cortical bone. The bisphosphonate alendronate has been...
Which tissues also produce hormones? What is a hormone? What do hormones do for the cells and tissues of the body? What are the only two hormones released from the neurohypophysis but produced by the hypothalamus? Match the name of the hormone with the gland that produces it. What two ...
Menstruation: The menstrual cycle of females on average lasts 28 days in humans and processes the anatomical and chemical changes in the reproductive system that allow for the potential fertilization of a mature oocyte by male sperm cells in the Fallopian/uterine tubes. Answe...
