Forearm. Radial artery runs along the forearm and winds at the wrist. Due to the position of the artery (close to the surface of the arm and distally located to the radius bone), it is used to check for cardiac rhythm and heart rate. You have often observed medics place two finger on your wrist to feel for pulse.
Blood can also be drawn from the artery to perform tests such as arterial blood gas.
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.

Answer:
(C) glycogen
Explanation:
The polysaccharide formed from the enzyme insulin as a means to remove glucose from the blood is glycogen.
When glucose level in blood rises insulin is released from Pancreas that promotes the uptake of glucose into liver cells converting glucose into long chain polysaccharide that are stored in the liver. Glucose makes 6-10% of the liver.
