How do muscles get signals from the brain?
Brain sends signal through spinal cord to nerves. Nerves contract which muscle to move and sends a message back to the brain. BOOM! Movement.
What Chemical enters a muscle cell upon excitation?
Acetylcholine is the chemical that crosses the synapse causing a muscle to contract. It is released due to an electrical impulse sent from your brain down your nervous system.
What type of nerve stimulates muscle cells to contract?
Somatic type of nerves stimulate the muscle cells to contract.
What travels from your brain to your skeletal muscle cells when you move?
When you decide to move, an electrical signal called an action potential is generated in your brain. This signal travels along your neurons and reaches the skeletal muscle cells via motor neurons. At the neuromuscular junction, a chemical called acetylcholine is released, which stimulates the muscle fibers to contract and initiate movement.
Inability of muscle fibers to contract after a long period of contraction?
This is likely due to muscle fatigue, which happens when muscle fibers become depleted of energy sources like ATP needed for contraction. Accumulation of waste products like lactic acid and a decrease in calcium availability can also contribute to muscle fatigue. Rest and replenishing energy sources can help muscles recover and regain the ability to contract.
How is the brain like a muscle?
no of course its not,it cannot contract and relax (horten and lengthen)
What do muscle nerves do?
muscle nerves carry messages from the brain to tell the muscle to contract.
Human skeletal muscle cells are signaled to contract by what?
I think its the brain using the spinal cord
How is your brain like your muscle?
Your brain is meat so it is a muscle.
How does neuronal firing cause muscle contraction?
When a neuron in a muscle is fired, or triggered, it sends a message to the brain telling the muscle to contract.
When a muscle contracts it does what?
In order for a muscle to contract, the brain sends a nerve impulse to the muscle it wants to contract. The nerve impulse triggers the potassium inside the muscle fiber cell to switch places with the calcium outside the cell wall, thereby feeding the cell and contracting the muscle. A second nerve impulse from the brain triggers the calcium to switch places with the potassium, releasing the contracted muscle.
Will the leg muscle contract when it is removed from the body and you pinch it?
No, as the muscle is dead (it doesn't contract like while the muscle is still alive either). However, it will contract if you give it an electrical "jump."
Can you find muscle tissue in plants?
yes because their is signals that contract from the brain to make the muscles move
If your brain tells your leg muscles to contract what carries the message to the leg muscle?
the nerves and the nervous system
How do muscles get signals from the brain?
Brain sends signal through spinal cord to nerves. Nerves contract which muscle to move and sends a message back to the brain. BOOM! Movement.
What two actions make muscle movement possible?
brain says move triceps triceps contract and moves
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.
