Question

DOUBLE DEFINITION: Moving Cell - ?​

Answer 1

Cell Movement and Mechanism

Explanation:

• Cell movement may be a complex phenomenon primarily driven by the actin network beneath the cytomembrane, and may be divided into three general components: protrusion of the vanguard of the cell, adhesion of the vanguard and adhesion at the cell body and rear, and cytoskeletal contraction to tug the cell forward.
• Cell movement may be complex and causes cell adhesion by the action or actions. The movement of cells is initiated by the chemicals that are present in the cell membrane and its surrounding structures.
• Rapidly moving cells can often yield the substrate without microtubules (​keratocytes, neutrophils), but crawling motility always requires actin.
