What process involves muscle contractions that move food through the esophagus molecules?
Different types of muscle contractions
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 is an Isotonic Contractions?
Isotonic contractions. This happens when the muscle shortens as it contracts
What is responsible for muscle contractions?
most often uncontrollable contractions are cause by one or several of the following: CNS stimulants, reflex triggers, anxiety, stress, many pharmaceuticals (SSRI's for example), & overworking muscles without prior stretching/loosening
Does isotonic muscle contractions involve shortening of muscle?
Yes
The strongest muscle contractions are normally achieved by what?
The strongest muscle contractions are normally achieved by increasing the stimulation up to the maximal stimulus. There are various classifications of contractions, including eccentric and concentric.
What is released to muscle cell receptors to trigger muscle contractions?
Acetylcholine
A deficiency of parathyroid hormone can cause involuntary muscle contractions of a type called?
Tetany is the term for the muscle contractions that may be caused by hypoparathyroidism.
What are the two muscle contractions?
Flexion and extension.
Uncontrolled muscle contractions the same as skeletal muscle contractions?
Uhh, no uncontrolled muscle contraction occurs in smooth and cardiac muscles... there are many differences between these two types of muscles; controlled and uncontrolled muscle contraction.....
