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'.
Secondary succession is a process started by an event (example forest fire) that reduces an already established ecosystem
Explanation:
In the analogy of a cell as a school, lysosomes could be thought of as a teacher.
Because teacher helps students by solving complex problems in simple way and as teacher lysosomes also helps us by breaking down the complex thing in the cell.
Answer:
The disease has been absent from the population for a long time.
Answer:
Option-C
Explanation:
A pulse-chase experiment which is used to study the cellular process taking place in the cells. This uses the labelled molecule which is incorporated into the cellular pathway and then the unlabeled molecules are used over time to determine how much time is required by the unlabeled molecule to replace the labelled molecule.
In the given question, the pancreatic cell which secretes the digestive enzyme known as the acinar cell is labelled with the leucine and then used unlabeled leucine.
When observed after three hours, the black spots will appear on the exterior of the cell as the protein has been synthesised by the ER and now has been secreted from the cell.
Thus, Option-C is the correct answer.
