Final answer:
Stenosis and sclerosis do not have the same meaning; stenosis is the narrowing of a body passage, while sclerosis refers to the hardening of tissue.
Step-by-step explanation:
The terms stenosis and sclerosis do not have the same meaning, so the correct answer to whether stenosis and sclerosis have the same meaning is false.
Stenosis refers to the narrowing of a passage in the body, such as arteries or valves. This can lead to a reduction in the flow of fluids, like blood, through that passage. For example, spinal stenosis means a narrowing of the openings within the spine, which can compress the nerves and cause pain and other problems.
In contrast, sclerosis refers to a hardening of tissue, often due to overgrowth of fibrous tissues or a calcification process. This term is commonly used in the context of multiple sclerosis, a neurological disease where the insulating covers of nerve cells in the brain and spinal cord are damaged.
