What else can I help you with?
What channels open when the nervous system signals a muscle to contract?
sodium ion
When the nervous system signals a muscle to contract what ion channels open?
When the nervous system signals a muscle to contract, calcium channels open in the muscle cell membrane. Calcium ions then flow into the muscle cell, triggering a series of biochemical events that eventually lead to muscle contraction.
What tells muscles when to contract?
Muscles contract in response to signals from the nervous system. Motor neurons release neurotransmitters that stimulate muscle fibers to generate a contraction. This process is initiated by electrical impulses called action potentials that travel along the nerves to the muscle cells.
What happens when these muscles contract?
When muscles contract, the brain sends signals through the nervous system to the motor neuron that supplies several muscle fibers. There are different versions of contraction, which includes voluntary and involuntary.
Does Electricity causes your muscles to contract?
Yes, electricity can cause your muscles to contract. This occurs because muscle contractions are triggered by electrical signals from the nervous system, which stimulate muscle fibers. When an electrical impulse reaches a muscle, it leads to the release of calcium ions, allowing the muscle fibers to contract. This principle is also utilized in medical therapies and devices, such as electrical stimulation for muscle rehabilitation.
What muscle can contract without the need for the nervous stimulation?
Smooth & cardiac muscle.
Is it true that the nervous system controls how your muscles move your bones?
Yes, that is correct. The nervous system controls muscle movement by sending electrical signals from the brain to the muscles via the spinal cord. These signals trigger the muscles to contract and relax, leading to movement of the bones.
Which type of muscle can contract without being stimulated by the nervous system?
cardiac muscle tissue
Name a structure that receives signals from autonomic nervous system?
Smooth muscle, cardiac muscle, gland
Is this true or false Muscle tissue sends electrical signals throughout the human body.?
False. Muscle tissue itself does not send electrical signals; rather, it responds to electrical signals sent by the nervous system. The nervous system generates these signals to initiate muscle contractions, allowing for movement. Muscle tissue can generate its own electrical impulses during contraction, but it does not communicate signals autonomously throughout the body.
What nervous system controls the skeletal muscle contractions?
The central nervous system supplies the body and muscle contraction. Striated muscle (skeletal muscle) contract voluntary with exception of the heart which is striated involuntary smooth muscle.
How does the nervous system and the circulatory system work with the muscular system?
The nervous system sends signals to make muscles move....Apexxx
