The gate control theory of pain states that the experience of pain is dependent on the complex interaction of the central and the peripheral nervous system. This theory was given by Ronald Melzack and Patrick Wall.
Usually, when a person experiences pain, the neurons transmits the message from the area of damage along the peripheral nervous system to the spinal cord and the brain. The gate control theory suggests that the neurons encounter the 'nerve gates' while transmitting the pain messages in the spinal cord. These opening and closing of these gates is dependent on the multiple factors.
The basket cells are the multipolar, inhibitory interneurons . Endorphins are the neuropeptide and the peptide hormones, which are secreted by the central nervous system and the pituitary gland. These structures have no relation with the transmission of the pain.
The hyperpolarization of the neurons by the opiate receptors resulting in the release of the substance P, which is a neurotransmitter involved with pain.
Hence, the correct answer is 'by releasing substance P'.
Answer:
Expanding triplet repeats
Explanation:
Expanding triplet repeats causes a disorder called Triple repeat disorder. It’s a genetic and dominantly inherited neurological disorder and is also classified as an unstable mutation.
Most of these disorders involve a CAG·CTG repeat expansion, such as Huntington disease etc.

Answer:
Nanotechnology is a field of producing materials and devices from atoms and molecules.
Explanation:
Nanotechnology is a field that concerned with producing materials and devices from atoms and molecules. A nanometer is one-billionth of a meter in size. Nanotechnology can be used to “recognize” the cells of interest which allows associated drugs to reach diseased tissue without damaging healthy cells. Nanotechnology produces new and faster kinds of computers, more efficient power sources and more effective medical treatments. Main disadvantages include threats to security, privacy, health and the environment. More research must be done in this field to get more benefits from it.
Answer:
Adaption is needed for a living thing to strive in a system, its how they survive.
Explanation:
Adaptation is needed to survive. This includes climate, predators around it etc. For example polar bears. Polar bears adapt to their environment by growing thick coats of fur. These coats keep the bears warm.Without it they would die.
