They also need to connect with other neurons to form communication networks so they have many long branches RBCs are shaped like a doughnut to carry more hemoglobin and to fit through small spaces.
WebBiological cells adopt a variety of shapes, determined by multiple processes and biophysical forces under the control of the cell. These shapes can be studied with different quantitative measures that reflect the cellular morphology (MGCKCKDDRTWSBCC2024). Web15 sep. 2009 · The shape of the cell is defined by the geometrical information of the space occupied by the cell and is determined by its external boundaries. It is the result of the mechanical balance of the forces exerted on the cell membrane by intracellular components and the outside environment 2, 3.
