[1] Motility is the ability of an organism to move independently using metabolic energy . This biological concept encompasses movement at various levels, from whole organisms to cells and subcellular components.
For instance, a well known example of sensitiveness to a specific type of biological motion is expert dancers observing others dancing. Compared to people who do not know how to dance, expert dancers show more sensitiveness to the biological motion from the dance style of their expertise. The same expert dancer would also show similar but less ...
Bacterial gliding is a process of motility whereby a bacterium can move under its own power. Generally, the process occurs whereby the bacterium moves along a surface in the general direction of its long axis. [5] Gliding may occur via distinctly different mechanisms, depending on the type of bacterium.
Run-and-tumble motion is a movement pattern exhibited by certain bacteria and other microscopic agents. It consists of an alternating sequence of "runs" and "tumbles": during a run, the agent propels itself in a fixed (or slowly varying) direction, and during a tumble, it remains stationary while it reorients itself in preparation for the next run.
Stride range of motion: the leg's integrated path between stance onset and swing offset. Joint angles: Walking can also be quantified through the analysis of joint angles. [ 10 ] [ 11 ] [ 12 ] During legged locomotion, an animal flexes and extends its joints in an oscillatory manner, creating a joint angle pattern that repeats across steps.
A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of the corkscrew-like flagella of many prokaryotes).
A ribosome is a biological machine that utilizes protein dynamics. Molecular biophysics is a rapidly evolving interdisciplinary area of research that combines concepts in physics, chemistry, engineering, mathematics and biology. [1]
The motion of a particle located at position can be described by the Smoluchowski's limit of the Langevin equation: [11] [12] = + (), where is the diffusion coefficient of the particle, is the friction coefficient per unit of mass, () the force per unit of mass, and is a Brownian motion.
