WebSensation is the activation of sensory receptors at the level of the stimulus. Perception is the central processing of sensory stimuli into a meaningful pattern involving awareness. Perception is dependent on sensation, but not all sensations are perceived. Receptors are the structures (and sometimes whole cells) that detect sensations. Web-Myofilaments (or filaments) are ultramicroscopic, thread-like structures found in myofibrils. -In other words, the myofilaments are bundled together to make a myofibril.

This term is typically used in opposition to a fast response. For instance, tonic muscles are contrasted by the more typical and much faster twitch muscles, while tonic sensory nerve endings are contrasted to the much faster phasic sensory nerve endings. biological regulation of weight psychology

http://pressbooks-dev.oer.hawaii.edu/anatomyandphysiology/chapter/nervous-system-control-of-muscle-tension/ WebAn important characteristic of skeletal muscle is its ability to contract to varying degrees. A muscle, like the biceps, contracts with varying degrees of force depending on the circumstance (this is also referred to as a graded response). Muscles do this by a process called summation, specifically by motor unit summation and wave summation.

WebGraded potentials are fast-acting, meaning that the membrane potential typically returns to resting membrane potential quickly, within a couple msec. The opening of mechanical or ligand-gated ion channels are what induce graded potentials.
