What else can I help you with?
What is GI motility and the release of GI secretion carefully regulated by?
Auntonomic efferents from the vagus (X) nerve
Do apocrine glands use exocytosis to make secretions?
No holocrine glands release their secretions by cell lysis, the entire cell disintegrates.
How Hormonal Secretions Are Regulated?
Most hormone secretions are regulated by negative feedbacks. The 3 main feed backs are:1)(Blood level of certain chemicals controls hormone secretion) Blood composition; Ex: blood glucose levels control the insulin secretion.2)(Hormones controlled by nervous system) Neural control; Ex: Epinephrine is release from adrenal medulla as result of nervous system stimulation.3)(Hormone secretion controlled by other hormones) Hormonal control; Ex: hormones from pituitary gland act on the ovaries and testes causing release of sex hormones.Source: Seeley's Essentials of Anatomy and Physiology (seventh edition)
What is merocrine secretion?
Merocrine secretion is a method of secretion in which secretory vesicles release their contents through exocytosis without the loss of cellular membrane. This process is common in glands that produce sweat, saliva, and digestive enzymes.
What are glands that release their secretions directly into the body fluids and help regulate metabolic processes?
endocrine glands
What three things regulate hormone secretions?
Hormone secretions are primarily regulated by three mechanisms: feedback systems, particularly negative feedback, which maintain homeostasis by adjusting hormone levels in response to changes in the body; hormonal regulation, where one hormone stimulates or inhibits the secretion of another hormone; and neural regulation, where the nervous system directly influences hormone release through nerve impulses. Together, these mechanisms ensure precise control of hormone levels to support bodily functions.
How do you release a lobster from its pot?
Carefully.
Do tree frogs release gases when threatened?
There are many types of tree frogs. Some do release noxious skin secretions that some preditors find unpalitable.
Why occur your cecretion?
Secretions in the body occur to perform various functions such as lubrication, protection, digestion, and communication within the body. Glands in the body produce and release these secretions in response to signals or stimuli that are part of normal physiological processes.
How are sweat and tear glands different from endocrine glands?
Sweat and tear glands are exocrine glands that release their secretions through ducts onto the body's surface, while endocrine glands release hormones directly into the bloodstream. Sweat and tear glands help regulate body temperature and protect the eyes, whereas endocrine glands regulate various physiological processes and maintain homeostasis in the body.
Does parasympathetic stimulation of the intestine increase or decrease motility and increase or decrease digestive gland secretion?
Parasympathetic stimulation of the intestine increases motility by promoting smooth muscle contractions and enhances digestive gland secretion by stimulating the release of digestive enzymes and fluids.
Do merocrine glands produce their secretions by accumulating their secretions internally until the cell ruptures?
No, as far as I can tell from definition, and as far as rupturing the cell, because definition of Merocrine is: "of or relating to a gland whose secretory cells remain undamaged during secretion".
