Why is calcium important for nervous system?
In neurons, calcium is the ultimate multitasker. It helps propagate electrical signals down axons. It triggers synaptic terminals to dump their cargo of neurotransmitters into synapses. And, if that's not enough, it's also involved in memory formation, metabolism, and cell growth.
What are the functions of calcium and phosphorus in the body?
Phosphorus works with calcium to help build bones. You need the right amount of both calcium and phosphorus for bone health. Phosphorus also plays an important structural role in nucleic acids and cell membranes. It's involved in the body's energy production as well.
Which of the following are functions of phosphorus quizlet?
Function for health: its main function is to work with calcuim to harden or ossify bones and teeth. calcium and phosphorus bind to form caluim phosphate, which is the ossifying agent for hard tissue. Phosphorus is also a component of DNA. its assists in the contraction of muscles and in the functioning of kidneys.
What is the main effect when one's intake of calcium is less than adequate quizlet?
Inadequate calcium and vitamin D intake during tooth formation and maturation can result in hypomineralization of developing teeth. Generally, inadequate calcium intake affects bone mass and tooth structure equivalently.
