A concentric contraction is the contracting muscle that initiates movement. the opposing (relaxing) muscle during muscle contraction. a muscle that contracts and shortens as a weight is lifted. a muscle that contracts and lengthens as a weight is lowered.

A concentric muscle action occurs when a muscle is exerting force greater than the resistive force, resulting in shortening of the muscle.

The contraction of a single muscle fiber can be divided into three stages: the period (time between stimulation and initiation of contraction), the period (when the muscle shortens), and the period (when the muscle returns to its former length). When the muscle is not allowed to relax completely between stimuli, occurs. The contractions gradually increase in intensity. When maximal sustained contraction is reached, is achieved. This stage will continue until occurs, and the muscle relaxes even though stimulation continues.

For each label, determine whether it describes contraction of smooth muscle or contraction of skeletal muscle. Then place in the correct column. Contractions include peristalsis. Stretching results in reflexive contraction. Only response to stimulation is contraction. Can contract in response to nervous stimulation or to hormones. Contraction only in response to acetylcholine. Can be stretched and still maintain tension. Response to stimulation can be contraction or inhibition of contraction. Slow to contract and to relax. Contraction in response to acetylcholine or norepinephrine. Contraction only in response to nervous stimulation. Smooth Muscle Skeletal Muscle
