What is the contraction phase?
The contraction phase refers to the stage of a muscle action where the muscle fibers shorten and generate force. This is when the muscle is actively contracting and pulling on the tendons to create movement.
What is the second phase of masters and johnson's sexual response cycle?
The second phase of Masters and Johnson's sexual response cycle is the plateau phase. This phase involves a continuation of the physiological changes that occurred during the excitement phase, leading to increased pleasure and arousal. It is characterized by further increases in heart rate, breathing, and muscle tension.
When was The Plateau Phase created?
The Plateau Phase was created in 1982-03.
What are the three stages of muscle cell contraction?
A Muscle Twitch is a single contraction of skeletal muscle. The three distinct phases are latent, contraction, and relaxation. Latent Phase: Is the interval from the stimulus application until the muscle begins to contract (shorten). Note that there is no traced activity during this phase, but there are some electrical and chemical changes taking place during this phase. Contraction Phase: This phase is when the muscle fibers shorten, the tracings will show during this phase (a) peak(s). Relaxation Phase: This phase is represented by the downward curve in your tracings, this is when the muscle is going back to its original state of relaxation and the muscle will once again lengthen
Of cephalic phase or celiac phase or plateau phase or intestinal phase or gastric phase which is not a phase of gastric regulation?
s phase
What is the significance of the plateau phase seen in the action potential of cardiac muscle cells?
The plateau phase in the action potential of cardiac muscle cells is important as it helps to prolong the refractory period, preventing rapid, repeated contractions that could lead to arrhythmias. It also allows for the synchronization of contractions between different regions of the heart, ensuring effective pumping of blood. This phase is primarily due to the balance of inward calcium and outward potassium currents.
What phase is between stimulus of a muscle and the shortening of the muscle?
The phase between the stimulus of a muscle and the shortening of the muscle is called the latent phase or latent period. During this phase, the muscle is receiving the signal to contract, but actual muscle shortening has not yet occurred. This period is important for the muscle fibers to prepare and generate enough force for contraction.
Nerve and muscle cells are in what phase?
G0 phase
What is the Prolonged plateau phase?
The prolonged plateau phase is a stage in the sexual response cycle where arousal is maintained at a high level for an extended period without reaching climax. It can occur in both males and females and may result in increased sexual tension and sensitivity.
What is a concentric contraction?
concentric contraction is atype of muscle contraction which the muscle shortens while genrating aforce The muscle shortens to produce movement. A muscle contraction in which shortening occurs.
Which phase of a muscle twitch is eliminated in complete tetanus?
relaxation phase
Explain the first and second phase of sexual activity?
The first phase of sexual activity is the arousal phase, characterized by increased blood flow to the genitals, muscle tension, and increased heart rate. The second phase is the plateau phase, where arousal continues to build and can lead to increased sensitivity and tension in the body.
