[1] [2] In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as when holding something heavy in the same position. [1] The termination of muscle contraction is followed by muscle relaxation, which is a return of the muscle fibers to their low ...
A Wiggers diagram modified from [1] A Wiggers diagram , named after its developer, Carl Wiggers , is a unique diagram that has been used in teaching cardiac physiology for more than a century. [ 1 ] [ 2 ] In the Wiggers diagram, the X-axis is used to plot time subdivided into the cardiac phases, while the Y-axis typically contains the following ...
Latent period (epidemiology), the time interval between when an individual is infected by a pathogen and when he or she becomes capable of infecting other susceptible individuals. Muscle contraction, the time between a stimulus to the nerve and the contraction of the muscle; Virus latency, a period during which a virus remains dormant in a cell ...
From there, an alpha motor neuron conducts an efferent impulse back to the quadriceps femoris muscle, triggering contraction. [3] This contraction, coordinated with the relaxation of the antagonistic flexor hamstring muscle causes the leg to kick. [4] There is a latency of around 18 ms between stretch of the patellar tendon and the beginning of ...
Period (two five-bar phrases) in Haydn's Feldpartita. Play ⓘ The second phrase is built of parallel (similar) melodic material, distinguished by an authentic cadence answering the half cadence at the end of the first phrase. [1] Period (two four-bar phrases) in Beethoven's Piano Sonata in C Minor, Op. 13 (Pathetique), second movement.
Cardiac diastole is the period of the cardiac cycle when, after contraction, the heart relaxes and expands while refilling with blood returning from the circulatory system. [ 1 ] [ 2 ] Both atrioventricular (AV) valves open to facilitate the 'unpressurized' flow of blood directly through the atria into both ventricles, where it is collected for ...
In January, a Japanese author admitted that her award-winning book, “The Tokyo Tower of Sympathy,” had been written with the help of ChatGPT. Shortly after receiving the Akutagawa Prize, Rie ...
Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
