Karl Hürthle
Karl Hürthle (March 16, 1860 – March 23, 1945) was a German physiologist and histologist who was a native of Ludwigsburg. In 1884, he received his doctorate from the University of Tübingen, where he remained until 1886, working as a prosector at the anatomical institute. At Tübingen, he was a student and assistant to physiologists Karl von Vierordt (1818-1884) and Paul Grützner (1847-1919). In 1887, he became an assistant to Rudolf Heidenhain (1834-1897) at the physiological institute in Breslau, and in 1895 attained the title of ''professor extraordinarius''. In 1898, he succeeded Heidenhain at the department of physiology in Breslau. Later in his career, he worked at the physiological institute at Tübingen, and also in the department of experimental pathology and therapy at the Kerckhoff Institute in Bad Nauheim (now known as the Max Planck Institute for Heart and Lung Research). Hürthle is remembered for contributions made in the field of haemodynamics. He performe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blood Pressure
Blood pressure (BP) is the pressure of Circulatory system, circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured. Blood pressure is usually expressed in terms of the systolic pressure (maximum pressure during one Cardiac cycle, heartbeat) over diastolic pressure (minimum pressure between two heartbeats) in the cardiac cycle. It is measured in Millimetre of mercury, millimetres of mercury (mmHg) above the surrounding atmospheric pressure, or in Pascal (unit), kilopascals (kPa). The difference between the systolic and diastolic pressures is known as pulse pressure, while the average pressure during a cardiac cycle is known as mean arterial pressure. Blood pressure is one of the vital signs—together with respiratory rate, heart rate, Oxygen saturation (me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hürthle Cell
A Hürthle cell is a transformed (metaplasia) thyroid follicular cell with "enlarged mitochondria and enlarged round nuclei with prominent nucleoli", resulting in eosinophilia in the cytoplasm. Oncocytes in the thyroid are often called Hürthle cells. Although the terms oncocyte, oxyphil cell, and Hürthle cell are used interchangeably, "Hürthle cell" is used only to indicate cells of thyroid follicular origin.Cannon, J. (2011). The Significance of Hurthle Cells in Thyroid Disease. The Oncologist. doi:10.1634/theoncologist.2010-0253 Diseases While Hurthle cells can occur in healthy thyroid glands, they are often associated with Hashimoto's thyroiditis and Graves' disease. Hürthle cell neoplasms can be separated into Hürthle cell adenomas (benign tumours) and carcinomas (malignant tumours) arising from the follicular epithelium of the thyroid gland. The latter is a relatively rare form of differentiated thyroid cancer, accounting for only 3-10% of all differentiated thyr ...

Epithelial
Epithelium or epithelial tissue is a thin, continuous, protective layer of cells with little extracellular matrix. An example is the epidermis, the outermost layer of the skin. Epithelial ( mesothelial) tissues line the outer surfaces of many internal organs, the corresponding inner surfaces of body cavities, and the inner surfaces of blood vessels. Epithelial tissue is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue. These tissues also lack blood or lymph supply. The tissue is supplied by nerves. There are three principal shapes of epithelial cell: squamous (scaly), columnar, and cuboidal. These can be arranged in a singular layer of cells as simple epithelium, either simple squamous, simple columnar, or simple cuboidal, or in layers of two or more cells deep as stratified (layered), or ''compound'', either squamous, columnar or cuboidal. In some tissues, a layer of columnar cells may appear to be stratified due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thyroid Gland
The thyroid, or thyroid gland, is an endocrine gland in vertebrates. In humans, it is a butterfly-shaped gland located in the neck below the Adam's apple. It consists of two connected lobes. The lower two thirds of the lobes are connected by a thin band of tissue called the isthmus (: isthmi). Microscopically, the functional unit of the thyroid gland is the spherical thyroid follicle, lined with follicular cells (thyrocytes), and occasional parafollicular cells that surround a lumen containing colloid. The thyroid gland secretes three hormones: the two thyroid hormones triiodothyronine (T3) and thyroxine (T4)and a peptide hormone, calcitonin. The thyroid hormones influence the metabolic rate and protein synthesis and growth and development in children. Calcitonin plays a role in calcium homeostasis. Secretion of the two thyroid hormones is regulated by thyroid-stimulating hormone (TSH), which is secreted from the anterior pituitary gland. TSH is regulated by th ...

Morphology (biology)
Morphology (from Ancient Greek μορφή (morphḗ) "form", and λόγος (lógos) "word, study, research") is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of the overall structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fried ...
