What cables transmit signals as pulses of light over glass strands inside protected tubing?
Fiber Optic cables carry data as light.
What liquid is inside the cochlea?
The cochlea contains a fluid called endolymph, which plays a crucial role in the process of hearing. Endolymph helps transmit sound vibrations to the auditory nerve, which sends signals to the brain for interpretation.
An electrical impulse moving down an axon is called?
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
How does the resting potential of a neuron work?
The resting potential of a neuron is the electrical charge difference across the cell membrane when the neuron is not sending any signals. This difference is maintained by the unequal distribution of ions inside and outside the neuron, with more sodium ions outside and more potassium ions inside. The resting potential allows the neuron to quickly generate and transmit signals when needed.
Where are neurotransmitters synthesized and stored?
Neurotransmitters are synthesized inside the neuron's cell body and stored in vesicles at the nerve terminal. When an action potential occurs, the neurotransmitters are released into the synaptic cleft to transmit signals to the next neuron.
What are DNA strands packed into?
DNA strands are packed into structures called chromosomes. Chromosomes are made up of long strands of DNA that are tightly coiled and condensed to fit inside the nucleus of a cell.
What is contained inside a synaptic terminal?
A synaptic terminal contains synaptic vesicles filled with neurotransmitters, which are chemical messengers that transmit signals between neurons. It also includes mitochondria for energy production, endoplasmic reticulum for protein synthesis, and other organelles necessary for synaptic function.
In a cell Which function is NOT accomplished by receptor proteins?
Receptor proteins do not typically carry out functions such as cell metabolism, protein synthesis, or DNA replication. Their main function is to receive and transmit signals from the extracellular environment to the inside of the cell.
Why does hyperpolarization cause a spike in neuronal activity?
Hyperpolarization causes a spike in neuronal activity because it increases the difference in electrical charge between the inside and outside of the neuron, making it more likely for the neuron to generate an action potential and transmit signals.
Intracellular chemical signals known as second messengers?
Second messengers are small molecules that transmit signals inside cells, amplifying and regulating the cellular response to the original stimulus. Common examples include cAMP, calcium ions, and IP3. They are crucial in cellular communication and are involved in a wide range of signaling pathways.
Inside the nucleus of a cell are strands of blank molecules that are important in cell reproduction?
Try DNA.
