What else can I help you with?
A muscle that causes a desired action and is often made more efficient with the assistance of synergists?
Agonist
What is a muscle that causes a desired action and is often made more efficient with the assistance of synergists?
The answer is AGONIST.
What is the action of the muscles that causes air to come into the lungs?
The action is the flattening of your diaphragm, or the muscle that helps your lungs inhale and exhale.
What and where are sarcomeres?
These are found in muscle cells. The action causes contractions. They cause a sliding or shortening movement.
What kind of stimulus travels from the motor neuron to skeletal muscle?
The stimulus that travels from the motor neuron to skeletal muscle is an electrical signal called an action potential. This action potential causes the release of neurotransmitters, specifically acetylcholine, which then stimulates muscle contraction.
The action potential is conducted into a skeletal muscle fiber by?
The action potential is conducted into a skeletal muscle fiber by the depolarization of the motor end plate, which triggers the opening of voltage-gated sodium channels. This causes an influx of sodium ions into the muscle fiber, leading to depolarization and the initiation of muscle contraction.
What is effector muscle for calcaneal reflex action?
The effector muscle for the calcaneal reflex (also known as the Achilles reflex) is the gastrocnemius muscle in the calf. When the Achilles tendon is tapped, it causes a contraction of the gastrocnemius muscle, resulting in plantar flexion of the foot.
The combining of the neurotransmitter with the muscle membrane receptors causes the membrane to become permeable to sodium ions and blank of the membrane?
The combining of the neurotransmitter with the muscle membrane receptors causes the membrane to become permeable to sodium ions and depolarization of the membrane. This depolarization triggers an action potential that leads to muscle contraction.
When horse pulls the cart the action is on what?
When a horse pulls a cart, the action is on the horse. The horse exerts force on the cart through its harness, which causes the cart to move. This action is a result of the horse's muscle power and body strength.
What causes an action potential when it binds the motor end plate?
When the neurotransmitter acetylcholine binds to the motor end plate, it triggers the opening of sodium channels in the muscle cell membrane. This influx of sodium ions leads to depolarization of the cell, creating an action potential that propagates along the muscle fiber, ultimately leading to muscle contraction.
What muscle that counteracts the action of another muscle?
antagonist muscle
What causes depolarisation of sarcolemma of muscle fibre?
An incoming action potential to an alpha motor neuron causes acetylcholine (Ach)release at the end plate, Ach binds to Ach receptors on the sarcolemma causing a sodium influx which causes depolarization.
