What does the contraction of the gastrocnemius muscle usually result in?
type of contraction of gastrocnemius muscle?
What extension of the lower arm is a result of the contraction of?
The Triceps muscle
How optimum resting length of a muscle will result in maximum force of a contraction?
Due to starling law,
Heart excitation nerve impulses that result in heart muscle contraction originates in?
the pacemaker area or the sinoatrial node
What is creatine made of?
Creatine is a result of the metabolism of protein. It is present in living tissue. It supplies the energy for muscle contraction.
What is the relationship between spinal cord injury and spasticity?
Spinal cord injury prevents the brain from telling the muscle to relax. The result is prolonged muscle contraction or spasticity.
What is contraction of muscles?
"Muscle contraction begins with an electrical nerve impulse that results in a release of Ca2+ ions into the myosin-actin structure. The calcium ions in turn produce conformational changes that result in the sliding of the threads through each other, shortening the myosin-actin structure. The collective effect of this process is the contraction of the muscle."
What triggers muscle contraction?
Muscle fibers generates throught the action of actin and myosin. Contraction of Voluntary muscles occurs as a result of conscious effort originating in the brain. The brain sends signals, in the form of action potentials,through the nervous system to the motor neuron that innervates the muscle fiber. Involuntary muscles like the heart or smooth muscles in the gut contracts as a result of unconscious brain activity stimuli endogenous to the muscle itself.
What causes lymph to move toward the heart?
The lymph is circulated via muscle movement. The lymphatic system is not closed and has no central pump; thus transport is slow and sporadic. Lymph movement occurs due to peristalsis (propulsion of the lymph due to alternate contraction and relaxation of smooth muscle), valves, and compression during contraction of adjacent skeletal muscle and arterial pulsation.
When does your muscle contract?
Voluntary muscle contraction is controlled by the central nervous system. Voluntary muscle contraction occurs as a result of conscious effort originating in the brain. The brain sends signals, in the form of action potentials, through the nervous system to the motor neuron that innervates several muscle fibers. In the case of some reflexes, the signal to contract can originate in the spinal cord through a feedback loop with the grey matter. Involuntary muscles such as the heart or smooth muscles in the gut and vascular system contract as a result of non-conscious brain activity or stimuli proceeding in the body to the muscle itself.
What does ventricular repolarization result in?
contraction
What painful muscle condition can result if you use a muscle too much and tear muscle fibers?
A muscle strain can result from overuse of a muscle and tearing of muscle fibers.
