A neuromuscular junction refers to the chemical synapse between the muscle fiber and the motor neuron.
The neuromuscular junction is the site of communication. It's made up of four cell types which are the <em>muscle fibers, motor neurons, Schwann cells, and motor neurons.</em>
The neuromuscular junction also sends signals from the motor neuron to the skeletal muscles. It is responsible for transmitting <em>action potentials </em>from the motor neurons to muscle contractions.

The base found in RNA nucleotides, but not in DNA, is uracil.
RNA and DNA share three bases: adenine, cytosine, and guanine. However, for the fourth base, DNA has thymine while RNA
has uracil. When forming base pairs, cytosine bases are matched with guanine, while adenine bases are matched with uracil or thymine.
Answer:
Inspiration (breathing in)
The diaphragm contracts and moves downwards. The intercostal muscles contract and move the ribs upwards and outwards. This increases the size of the chest and decreases the air pressure inside it which sucks air into the lungs. During normal breathing, the major inspiratory muscles produce rib cage expansion and a downward movement of the diaphragm. These movements cause the pressure around and in the lung to become negative (relative to atmospheric pressure).

Answer:
EEG or electroencephalography
Explanation:
Electroencephalography or EEG is a technique to measure all the brain waves. These waves are occurred due to emotion, stress, or any change in stimuli received by the brain.
This is a technique where small metals are used to attach in the brain and detects the brain electrons wave. By using this technique individuals mental disorders like epilepsy and sleep disorders can be detected.
EEG measures the electrical activity of the brain. It also detects the activity of a large group of neurons.
Music therapy is also used with EEG to detect the anxiety, depression, of a person. As music induces strong emotions in a person, EEG is detected with music therapy.
But there are some limitations in this technique - it only detects the changes in the brain waves in the cortex, as the metals are attached to the skull. It can not measure deeper brain waves.
EEG also can't tell the exact location, where the brain wave changes. Because in a single time, it records several neuronal waves.
Besides these limitations, EEG is a useful technique to detect mental disorders.
