What else can I help you with?
What are two mechanisms that control motility and secretion of the digestive system?
peristalsis and segmentation
Gastrin secretin and cholecystokinin are examples of?
Gastrin, secretin, and cholecystokinin are examples of hormones that play roles in the regulation of the digestive system. Gastrin stimulates gastric acid secretion, secretin stimulates pancreatic bicarbonate secretion, and cholecystokinin stimulates gallbladder contraction and pancreatic enzyme secretion.
How do sympathetic and parasymphatetic activity affect gastric secretion?
Sympathetic activity inhibits gastric secretion by causing vasoconstriction of blood vessels in the stomach lining. Parasympathetic activity stimulates gastric secretion by increasing blood flow and activating gastric glands, leading to increased production of stomach acid and digestive enzymes.
What cranial nerve affects smooth muscle in the stomach?
The cranial nerve that affects smooth muscle in the stomach is the vagus nerve, or cranial nerve X. It plays a crucial role in the autonomic nervous system, particularly in promoting parasympathetic activity, which stimulates digestive processes. The vagus nerve innervates the smooth muscle of the stomach, facilitating peristalsis and the secretion of digestive enzymes.
In which portion of digestive system are there no secretion or digestion?
There is no secretion or digestion in the esophagus. It is a muscular tube that connects the mouth to the stomach and serves as a passageway for food to travel down to the stomach through a process called peristalsis.
Which hormone stimulates the secretion of milk?
prolactin
What stimulates the secretion of breast milk?
The hormone oxytocin stimulates the secretion of breast milk. It is released when a baby suckles at the breast, triggering the milk ejection reflex.
How can FSH be the cause of not producing eggs?
FSH, secreted by the Pituitary gland,stimulates the secretion of Oestrogen from the ovaries, Oestrogen in turn stimulates the secretion of LH by the pituitary and inhibits the secretion of FSH, LH then stimulates ovulation (the release of an egg). Without FSH this chain reaction does not happen.
Which anterior pituitary hormone shows increased secretion in response to stress?
That hormone is called as ACTH or adrenocorticotropic hormone. It stimulates the adrenal cortex to produce corticosteroids.
What structure controls secretion of hormones from the anterior pituiary gland?
The brain controls the secretion of digestive enzymes. The brain tells your body when there is food that needs to be digested.
What stimulates the secretion of estrogen?
Oestrogen stimulates the hormone LH. LH is secreted in pituitary gland and stimulates the release of an egg
What hormone stimulates secretion from the adrenal cortex?
What a weird question!
