What is the function of the chief cells of the parathyroid?
Gastric chief cells are in the digestive system. They release pepsinogen which is a digestive enzyme that when activated by hydrochloric acid turns into pepsin and helps in the digestion of proteins. Chief cells may also refer to parathyroid chief cells which produce and secrete parathyroid hormone when stimulated by low levels of calcium.
What is the secretary cell of parathyroid gland?
The secrotory cells of the parathyroid gland have the ability release chemicals, for example, the chief cells which secretes the parathyroid hormone.
Which gland secretes parathormone?
Parathyroid chief cells secretes parathormone.
What do parietal cells and chief cells produce together?
Parietal cells produce cover cells and chief cells produce micro and megaspores
What cells produce pepsinogen and hcl?
Chief cells of the stomach (gastric glands in stomach have chief cells)
What organ has chief and parietal cells?
Chief and parietal cells are found in the fundic zone of the stomach.Chief cells produce pepsinogen, and parietal cells produce hydrochloric acid. Both of these products assist in the chemical breakdown of stomach contents.
How are chief cells activated?
Gastric chief cells (as opposed to the chief cells present in the parathyroid gland) are the zymogen cells in the stomach that release pepsinogen (a precursor (zymogen) of pepsin). Without stimulation chief cells normally secrete pepsinogen at about 20% of the maximum ability. ACh (released by nerves) is the most important pathway for gastric chief cell activation. ACh also stimulates parietal cells, which secrete HCl (stomach acid). The fall in pH causes a reflex which further stimulates chief cells. Alternatively, acid in the duodenum (the first portion of the small intestine), stimulates release of secretin from S cells of the small and large intestine. Secretin also activates gastric chief cells.
Does the gallbladder produce hydrochloric acid?
No, the gall bladder does not produce hydrochloric acid the oxyntic cell (chief cells) produce the hydrochloric acid.
What gland secretes pth?
Parathyroid hormone (PTH), parathormone or parathyrin, is secreted by the chief cells of the Parathyroid Glands as a Polypeptide containing 84 amino acids.Basically these glands are present behind the thyroid gland and varies in number. The main function of PTH is to increase Blood Ca2+ level.
What are the similarities and differences between parietal cells and chief cells in the wall of the stomach?
both cell produce gastric juice to digest the food
What do chief cells in the stomach produce?
theses cells produce gastric enzymes such as pepsinogen and lipase. this helps digest triglercerides into free fatty acids and di, mono-glycerides. hope this was helpful:)
Which hormones stimulate gastric juice secretion?
You have the glands in the wall of stomach. You have the cells that secrete the mucus. You have the chief cells that secrete the precursor of the enzyme pepsin. This precursor is called as pepsinogen. Then you have the parietal cells that produce the hydrochloric acid. You have the hormones that induce the production of the gastric juice, when food enters the stomach. The same is controlled through the autonomic nervous system also. Like when you see or smell the food.
