Introduction to Cell Components: Cell Membrane, Nucleus, and Cytoskeleton

Cell Biology

• The main function of the cell membrane is to regulate what enters and leaves the cell.

Cellular Organelles

• The nucleus is described as the 'brain of the cell' because it contains the cell's genetic material.
• The nucleolus is responsible for ribosome synthesis and plays a crucial role in protein synthesis.
• DNA is the component associated with cancer as a disease of nucleic origin.
• The common feature in neurodegenerative diseases related to the cytoskeleton is the abnormal aggregation of cytoskeletal proteins.
• Mitochondria are the organelles responsible for ATP production.
• The centrioles are responsible for forming the spindle fibers in mitosis of every cell.
• Lysosomes are particularly abundant in cells with great phagocytic activity, such as macrophages.
• Ribosomes are the organelles responsible for protein synthesis.
• Lysosomes are involved in the process of autophagy and heterophagy, which are mechanisms of cellular recycling.
