Cell motility can be classified into several types, including:
1. Amoeboid Movement: Characterized by the extension of pseudopodia, commonly seen in amoebas and certain immune cells like macrophages. 2. Mesenchymal Movement: Involves the formation of protrusions and focal adhesions, typical of fibroblasts and cancer cells. 3. Collective Cell Migration: Cells move as a cohesive group, maintaining cell-cell junctions. This is observed in tissue formation and cancer metastasis. 4. Flagellar and Ciliary Movement: Movement is facilitated by whip-like appendages called flagella and cilia, seen in sperm cells and epithelial cells of the respiratory tract respectively.
