When the kidneys return salts and water to the blood it is called?
Reabsorption via a process called "secretion".
What are the small sacs within the axon terminal called?
They are called as vesicles. They are constantly created. They contents the neurotransmitter. Neurotransmitter is required for transmission of the nerve impulse.
What is a process whereby one neuron communicates with another neuron?
When nerve impulses are triggered near the soma/cell body, an electrical current known as the ACTION POTENTIAL sweeps through the axon and into the axon terminal. When the action potential reaches the tips of the axon terminal, it causes the synaptic vesicles to move towards the membrane of the terminal buttons. The buttons then open up and release the neurotransmitters (drugs.) The neurotransmitter molecules cross over the synaptic gap and attach themselves unto the receptor sites of the other neuron. After accomplishing their work on the receptor sites, some of the neurotransmitter molecules are broken down into other chemicals in a process called Degradation. The rest of the neurotransmitter molecules are taken up by the vesicles for reuse in a process called Reuptake.
The transport mechanism for a neurotransmitter across the synaptic cleft is called?
simple diffusion
Combinbations of molecules are called?
combinations of molecules are called elements.
The reabsorption of a neurotransmitter after it has transmitted a neural impulse is called?
Reuptake
The process in which enzymes within neurons convert precusors into neurotransmitter molecules is called?
Synthesis
When the kidneys return salts and water to the blood it is called?
Reabsorption via a process called "secretion".
What are three ways neurotransmitters are removed?
3 ways neurotransmitters can be removed: 1. Reuptake- reabsorption of the neurotransmitter into the neuron. 2. Enzymatic degradation- destruction of the neurotransmitter with special chemicals called enzymes. 3. Diffusion- The neurotransmitter becoming detached from the receptor and drifting out of the synaptic cleft.
A chemical found in the synaptic vesicles that when released has an effect on the next cell is called a?
neurotransmitters
What is the substance released at axon terminals?
The substance that is released at an axonal ending to propagate the nerve impulse to the next nerve or muscle is called
When water moves from a nephron in the kidney back to the blood it is called?
Reabsorption
What are the small sacs within the axon terminal called?
They are called as vesicles. They are constantly created. They contents the neurotransmitter. Neurotransmitter is required for transmission of the nerve impulse.
Chemical substance released at the axon terminals are called?
the signals are known as Action pottential. and the chemical substances or signal molecules are known as Neurotransmiters
What part of the renal tubule has an elaborate countercurrent mechanism for reabsorption of sodium and water?
A part of the tubule called the Loop of Henle is involved in the reabsorption of sodium and therefore water.
Cocaine cause the sudden release the brain of a neurotransmitter called?
True. Cocaine causes the sudden release in the brain of a neurotransmitter called dopamine. Source. Prentice Hall
What are the small vesicles containing neurotransmitter substances called?
acetylcholine
