Answer:
Stellate cells are resident lipid-storing cells of the pancreas and liver that transdifferentiate to a myofibroblastic state in the context of tissue injury. Beyond having roles in tissue homeostasis, stellate cells are increasingly implicated in pathological fibrogenic and inflammatory programs that contribute to tissue fibrosis and that constitute a growth-permissive tumor microenvironment. Although the capacity of stellate cells for extracellular matrix production and remodeling has long been appreciated, recent research efforts have demonstrated diverse roles for stellate cells in regulation of epithelial cell fate, immune modulation, and tissue health. Our present understanding of stellate cell biology in health and disease is discussed here, as are emerging means to target these multifaceted cells for therapeutic benefit.
To calculate the mass of a single atom, you would need to add up the protons and neutrons of a single atom.
Answer:
The correct answer is: is controlled by the somatic nervous system.
Explanation:
The urethra is an organ that is part of the urinary system, and consists of a tube that connects the urinary bladder to the urinary meatus, which is important for the excretion of urine. The urethra has two sphincters, which are muscles with the function to control the exit of the urine: <u>the internal urethral sphincter and the external urethral sphincter</u>.
The external urethral sphincter, unlike the internal one that is composed of smooth muscle, is made of skeletal muscle and is controlled by the somatic nervous system - this is what makes urination voluntary. Being the most external sphincter, it opens after the internal urethral sphincter during the micturition reflex.
Any damage in either sphincter can produce incontinence.
The correct option is D.
Antibiotic resistant is said to occur, when a particular antibiotic has lost its capacity to effectively eliminate or control the growth of a particular type of bacteria. In this case, the bacteria continues to grow and multiply in the present of the antibiotic drug. Antibiotic resistant usually occur when a bacteria has develop a variation that makes it possible for it to inactivate the antibiotic drug that is used against it. A bacteria that is formerly susceptible to a particular antibiotic may later become resistant to the same drug by developing variations that inactivate the antibiotic drug that is administer to destroy it.
