1. Muscle Cells: These cells are responsible for movement, and they are highly specialized for this function. They contain unique proteins that allow them to contract and relax, producing force. There are different types of muscle cells, including skeletal muscle cells, smooth muscle cells, and cardiac muscle cells.

2. Nerve Cells (Neurons): These cells are responsible for transmitting information throughout the body. They have long, slender projections called axons that carry signals to other cells, and dendrites that receive signals from other cells. Neurons are essential for communication, sensation, and thought.

While plants have cells that perform similar functions, like conducting signals and providing support, these cells are structurally and functionally different from animal muscle and nerve cells.
