Kris' case is unusual, because parkinson's disease usually takes many decades to kill enough neurons (cells in the brain) to cause the symptoms that we see in this young man. under normal circumstances neurons contain the structural components found in any typical cell in the body. if the cytoskeleton of kris' neurons is damaged, what could happen?

Answer;

-The neurons would be unable to transport substance between different parts of the cell.

Explanation;

-Neurons are specialized eukaryotic cells that extend long processes to form connections in the nervous system. They have a cytoskeleton that consists of three main polymers: microtubules, intermediate filaments and actin filaments.

-The cytoskeleton is required for axon formation and axonal transport and also provides the structural basis for several specialized axonal structures, such as the axon initial segment and presynaptic boutons.

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
