Chromaffin cells Principal cells O Parafollicular cells O Chief cells Follicular cells The cells of the pars distalis (anterior pituitary) can be classified as acidophils or basophils depending on their affinity for acid or basic dyes, respectively. The pars nervosa is the posterior lobe. Between all these organelles is the space in the cytoplasm called the cytosol. They secrete calcitonin. c. Parafollicular cells d. Lactotropic cells 9 major cell types, which form the human body, in a fun online biology learning game. This type of T-cell is also called "CD4 positive," or CD4. Which cell is a also called a septal cell? The endocrine portion of the pancreas secretes insulin, glucagon, and somatostatin. Parafollicular cells are pale-staining cells found in small number in the thyroid and are typically situated basally in the epithelium, without direct contact with the follicular lumen. The infundibulum connects the pituitary to the hypothalamus. Tropic hormones affect cellular activity in their target organ. The cell is the basic unit of life in all organisms. Within the islets, there are several cell types. Phloem, also called bast, tissues in plants that conduct foods made in the leaves to all other parts of the plant.Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells. These are called _____ cells. The acidophils are the somatotropic cells and the lactotropic cells. thrombocytes. They are always situated within the basement membrane, which surrounds the entire follicle. a. Alpha cells a. Pancreas The primary function of these cells is to secrete calcitonin. All rights reserved. b. Thyroid An antigen-presenting cell (APC) or accessory cell is a cell that displays antigen complexed with major histocompatibility complexes (MHCs) on their surfaces; this process is known as antigen presentation. Revising the embryonic origin of thyroid C cells in mice and humans. What are the cells of the pineal gland called? ... DNA segments at the end of chromosomes that play a part in cell age are called: telomeres. d. Pars nervosa e. Gonadotropic cells. The pancreas is both an endocrine and exocrine organ.

The cells of the adrenal medulla are chromaffin cells. These cells are large and have a pale stain compared with the follicular cells. e. All of the above are part of the adenohypophysis. In parasitology, a nurse cell is an infected cell in the disease trichinosis discovered by Dickson Despommier. e. Adrenal gland (medulla). Before a cell becomes specialised, it first starts out as a stem cell. Our Two Cell Types Your body is made of two basic cell types. The term phenotype refers to all the observable characteristics of a cell (or organism); its shape (morphology); interactions with other cells and the non-cellular environment (also called the extracellular matrix); proteins that appear on the cell surface (surface markers); and the cell's behavior (e.g., secretion, contraction, synaptic transmission). b. Corticotropic cells Amylin slows the rate of glucose entering the bloodstream, making it a more short-term regulator of blood glucose levels. Parafollicular cells are derived from pharyngeal endoderm. c. Pinealocytes The adenohypophysis can be further sub-divided into the pars distalis, pars intermedia, and pars tuberalis. Instructions: For each histology question, pick the one best answer. Follicular cells release and store thyroid hormone. Thyrotropic cells secrete thyroid stimulating hormone (TSH). Kupffer cells residing in the liver are a type of _____. e. PP cells. neutrophils. The adenohypophysis (more specifically, the pars distalis of the adenohypophysis) secretes tropic hormones. d. Catecholamine The pituitary can be subdivided into the adenohypophysis and neurohypophysis. Platelets are also called _____. B cells are a class of white blood cell known as a lymphocyte. T-helper cell: A type of T cell that provides help to other cells in the immune response by recognizing foreign antigens and secreting substances called cytokines that activate T and B cells. Like humans and animals, plants are also composed of several cells. Which of the following is not part of the adenohypophysis? In addition to insulin, beta cells also secrete the hormone Amylin and called C-peptide, a byproduct of insulin production. Neurons (also called neurones or nerve cells) are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at … Brush cells are occasionally, but rarely, seen in the alveolar epithelium. Beta cells Which cell type are also called C cells? Steroid hormones are cholesterol derivatives. a. Pars intermedia The type II pneumocyte secretes surfactant. e.g. c. Zona glomerulosa d. Delta cells b. are also called cytotoxic T cells. b. Zona reticularis The basophils are the gonadotropic cells, corticotropic cells and thyrotropic cells. They are located adjacent to the thyroid follicles and reside in the connective tissue. Parafollicular cells were previously believed to be derived from the neural crest based on a series of experiments in quail-chick chimeras. These cells are large and have a pale stain compared with the follicular cells. b. Pars tuberalis It secretes mineralocorticoids (such as aldosterone), glucocorticoids (such as cortisol) and sex steroids. Question 23 of 25 4.0/ 4.0 Points The cells that make up nearly all of the body contain an equal number of chromosomes that they receive from each parent. c. Somatotropic cells a. Lactotropic cells There are two cell types in the thyroid: follicular cells and parafollicular cells. Adult stem cells are sometimes also called somatic stem cells. What cell type secretes prolactin?
