Epithelial, muscle, connective, And nervous.
epithelial covers the body surface, connective tissues support and protect (serve many functions) the nervous tissues receive stimuli while alsoconduction to and from all over the body, lastly muscle tissues.
muscles tissue consist of three types :/
skeletal, smooth and cardiac. skeletal muscle is use to help contract the skeleto., the cardiac muscle is found within the heart, and the smooth muscle is found in the walls of internal organs and blood vessels
hope this helped.
Answer:
1. Potassium
2. increasing towards zero
3. hyperpolarization
4. voltage-regulated Potassium
Explanation:
Membrane potential can be defined as the difference in electric charges inside and outside of a cell. The resting membrane potential (RMP) occurs when there is no net current across the membrane and therefore the cell is in a non-excited state. At the RMP, sodium ions (Na+) are more concentrated inside the extracellular fluid (ECF) than inside the intracellular fluid (ICF), while potassium ions (K+) are more concentrated inside the ICF. The diffusion of K+ outside the cell triggers its hyperpolarization, by becoming the membrane potential more negative compared to the resting potential. As the potential nears +35 mV, the voltage-regulated potassium channels are open, thereby K+ ions leave the cell down its concentration gradient, while voltage-gated Na+ channels become saturated and inactivate.
