Agents that paralyze skeletal muscle by simple competitive inhibition of acetylcholine at muscle receptor sites are called?
a. nondepolarizing
b. depolarizing
c. antagonizing
d. repolarizing
Answer:
a. nondepolarizing
Explanation:
As the nerve impulse arrives, the synaptic end bulbs of the motor neurons release acetylcholine in the synapse. Acetylcholine binds to its receptors present at the motor endplate. This results in the opening of an ion channel in the ACh receptor to allow the movement of the Na+ into the cell. This makes the inside of the muscle fiber more positively charged, that is, depolarized.
Depolarization triggers a muscle action potential. Drugs or chemicals that paralyze skeletal muscle by competitive inhibition of acetylcholine at muscle receptor sites are called non-depolarizing as they do not allow the acetylcholine to facilitate the depolarization of the muscle fiber.
<span>Traction
The question pretty much defines the term "traction" as used in orthopedic medicine. There are two main types of traction, skin traction and skeletal traction. If traction is used, it is generally used in conjunction with some other form of treatment.</span>
The medulla is the inner region of the parenchyma of the kidney. The medulla consists of multiple pyramidal tissue masses, called renal pyramids.
The kidney's parenchyma's interior section is called the medulla.
The renal pyramids, which are triangle-shaped structures with a dense network of nephrons within them, are a collection of several pyramidal tissue masses that make up the medulla.
The Bowman's capsule, which is shaped like a cup and is located in the cortex of the kidney, is at one end of each nephron. The glomerulus, a group of capillaries that conducts blood from the renal arteries into the nephron where plasma is filtered via the capsule, is encircled by it.
The filtered fluid exits the capsule and travels via the collecting ducts and distal convoluted tubule before exiting the body through the ureter. It then travels down the proximal convoluted tubule to the loop of Henle. The complicated management of water and ion concentrations in the body is made possible by the numerous components of the nephrons, each of which is selectively permeable to distinct molecules.

Answer:
Smooth endoplasmic reticulum
The eruption of the fluid lava causes the flow of the liquid present inside the volcano. The lava flow is referred to the streams of the fluid which come out of the lava during the eruption.
The fluid lava can be erupted either when the non explosive activity of the fountain occurs or when the explosion in volcano causes fountain of fluid lava to come out.
So, the correct answer is Lava Flow.
