What is the neurotransmitter that initiates muscle contraction?
Voluntary muscle contraction is controlled by the central nervous system. The brain sends signals, in the form of action potentials, through the nervous system to the motor neuron that innervates several muscle fibers.Acetylcholine (ACh) is commonly secreted at neuromuscular junctions, the gaps between motor neurons and muscle cells, where it stimulates muscles to contract (by opening gated positive ion channels).
Whats the name of the chemical in the muscular system that causes contraction?
There's more than one chemical that causes contraction. The neurotransmitter (usually acetylcholine) is released from the nerve and excites the muscle. There is a change in calcium, sodium and potassium ion concentrations. ATP is used. All of these work together to produce a muscle contraction.
What is the neurotransmitter used to cause contractions in muscles?
Acetylcholine
How is bracing used in spasticity?
Bracing may be used to support a weak muscle, or to prevent excess contraction of a spastic muscle.
What word a noun is used to describe muscle shortening with stimulation?
The noun for muscle shortening is called contraction.
What is the medical term meaning without contraction?
Asystole means without contraction of the heart. Atony is a term used to denote no normal muscle contraction of the uterus.
When is botulinum toxin injection used?
In conditions of excessive and inappropriate muscle contraction, spasticity (persistent states of muscle contraction), sphincter contraction, eye-movement disorders, tics and tremors, and cosmetically to treat facial lines and wrinkles.
What type of muscle contraction is performed slowly and used to resist a weight or gravity?
Concentric
The myofilaments used during muscle contraction will return to their resting state when the relax?
actin
Why do you need fatty acids?
Fatty acids are used as fuel for muscle contraction and general metabolism.
What is muscle force and its vector representation?
Muscle force is the force produced by the contraction of a muscle. Force vectors, torque vectors, and difference vectors can all be used to help describe this force.
Does a skeletal muscle fiber contain many nuclei?
Skeletal muscle fibers contain numerous nuclei. This is used to produce large amounts of the enzymes and structural proteins needed for muscle contraction.
