What substance is released by the nervous system and excites muscle cells?
Calcium
Where are the calcium ions stored in the muscle cells?
terminal cisternae of the sarcoplasmic reticulum
What organelle makes steriods in gland cells regulates calcium in muscle cells and break down toxins in liver cells?
lysosomes
What organelle synthesizes steroids in the ovary and stores calcium in muscle cells?
Smooth ER
What is the organelle that makes steroids in gland cells regulates calcium in muscle cells and breaks down toxins in liver cells is the?
The endoplasmic reticulum is involved in the production of steroids, the regulation of calcium and the breakdown of toxins.
What is done by calcium channel blockers?
Calcium channel blockers block the entry of calcium into muscle cells in artery walls. Muscle cells need calcium to constrict, so reducing their calcium keeps them more relaxed and lowers blood pressure.
What is calcium channel blockers?
A calcium channel blocker is a drug that lowers blood pressure by either preventing calcium from entering cells of the cardiac muscle, or the smooth muscle cells of the blood vessel walls.
What is a calcium channel blocker?
Calcium channel blockers are medicines that slow the movement of calcium into the cells of the heart and blood vessels.
Which organelle contains calcium in muscle cells?
sarcoplasmic reticulum
What substance is released by the nervous system and excites muscle cells?
Calcium
In certain kinds of muscle cells calcium ions are stored?
Smooth ER
Where are the calcium ions stored in the muscle cells?
terminal cisternae of the sarcoplasmic reticulum
Chemical a binds and blocks acetylcholine receptors of muscle cells chemical b floods the cytoplasm of muscle cells with calcium ions which would make the best muscle relaxant and why?
Chemical A, because if the cytoplasm is flooded with calcium, then the actin and myosin would slide into eachother, causing the muscle to contract.
What organelle makes steriods in gland cells regulates calcium in muscle cells and break down toxins in liver cells?
lysosomes
What structure lets calcium ions enter cardiac muscle cells?
sarcoplasmic reticulum
What organelle synthesizes steroids in the ovary and stores calcium in muscle cells?
Smooth ER
What is the organelle that makes steroids in gland cells regulates calcium in muscle cells and breaks down toxins in liver cells is the?
The endoplasmic reticulum is involved in the production of steroids, the regulation of calcium and the breakdown of toxins.
