Cellular Processes

• Endocytosis: A process where cells engulf large particles or whole cells by enclosing them in vesicles.

  • Phagocytosis: Involves the ingestion of whole cells or large particles (e.g., bacteria) by white blood cells.

  • Pinocytosis: Often referred to as "cell drinking," involves the uptake of fluids and dissolved substances.

Neuron Structure

• Nerve Cells (Neurons): Specialized cells that transmit information throughout the body.

  • Can be very long, for example, some neurons are the length of an arm, allowing them to efficiently carry signals from one part of the body to another.
