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. WebJul 6, 2024 · Definition Resting membrane potential (EM) originates from the different concentrations of ions (expressed in mmol/l) at the inner and outer surface of the cell membrane. There are four excitable tissues in our body, and all of them have different EM values: Skeletal muscle cell = -90 millivolts (mV) Smooth muscle cell = -55mV

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.
