Changing … WebTonic in physiology refers to a physiological response which is slow and may be graded. 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.

For sensory neurons, which do not have a cell body between the dendrites and the axon, the initial segment is directly adjacent to the dendritic endings.

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 response curves depict the dependence of continuous outcomes on dose in individuals or individual samples (Figure 1).Examples of continuous outcomes include blood pressure, enzymatic activity, weight, essential nutrients (i.e., those that must be consumed in the diet), or any other outcome that is actually or presumptively associated with animal …
