B) The effected neurons in the CNS regenerate gradually.
C) The path of impulses in the nervous system may be disrupted.
D) Both (A) and (B)
Answer:
The answer is c)The path of impulses in the nervous system may be disrupted
Explanation:
A spinal cord injury causes apoptosis of the oligodendrocytes found on damaged areas of the cord, several days or weeks later. The death of these oligodendrocytes is another serious consequence of the lesion, since these cells are what make up myelin, which is the one that envelops the axons, accelerating the direction of nerve impulses. This apoptosis causes axons that are still intact to lose myelin, which incapacitates the spinal cord to communicate with the brain.
b. oceans
c. plastics
d. animals
Answer:
Stem cells are special human cells that are used to repair damaged tissues
Answer:
In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and divide indefinitely to produce more of the same stem cell. Stem cells are undifferentiated cells that can turn into specific cells, as the body needs them. Scientists and doctors are interested in stem cells as they help to explain how some functions of the body work, and how they sometimes go wrong.

Answer:
The muscular system
Explanation:
The muscular system is a set of muscles that can be controlled voluntarily by a living organism (skeletal muscles) Its main function is to achieve mobility, an action that takes place when electrical stimuli from the nervous system cause the contraction of muscle fibers . Muscles that contract automatically such as heart muscle or smooth muscles are not usually considered part of the muscular system. The whole skeletal musculature corresponds to approximately 40% of the weight of an adult man. The sum of the muscular system plus the bone system formed by the bones gives rise to the musculoskeletal system.
The muscles of the chest, such as the diaphragm, play a crucial role in breathing by changing the size of the thoracic cavity. This relates to the muscle rules as the diaphragm contracts and relaxes to facilitate inhaling and exhaling.
The muscles of the chest play a key role in breathing by changing the size of the thoracic cavity. This allows for the expansion and contraction of the lungs. One example of a chest muscle is the diaphragm, which is dome-shaped and separates the chest from the abdominal cavity.
The structure and function of the diaphragm relate to the muscle rules because it is a skeletal muscle that contracts and relaxes to facilitate breathing. The diaphragm contracts when you inhale, flattening and enlarging the thoracic cavity, while it relaxes when you exhale, allowing the chest to fall.
