Smooth & cardiac muscle.
What else can I help you with?
Which type of muscle CANNOT contract without being stimulated by the nervous system?
Cardiac muscle. Unlike skeletal and smooth muscle, the contraction of cardiac muscle is involuntary and requires stimulation from the nervous system. This ensures that the contractions of the heart are synchronized and coordinated.
Which type of muscle can contract without being stimulated by the nervous system?
cardiac muscle tissue
Skeletal muscles need nerve stimulation for contraction to occur?
Yes, nerve stimulation is necessary for skeletal muscles to contract. This stimulation causes an action potential to travel down the motor neuron, leading to the release of acetylcholine at the neuromuscular junction, which triggers muscle contraction by causing calcium release in the muscle fiber. Without this nerve input, skeletal muscles would not be able to contract voluntarily.
After nervous stimulation of the muscle cell has ceased the calcium in the muscle?

Do Cardiac muscle fibers need outside nervous stimulation in order to contract?
No, cardiac muscle fibers do not require outside nervous stimulation to contract. They have an inherent ability to generate action potentials due to specialized pacemaker cells, primarily located in the sinoatrial (SA) node. This intrinsic property allows the heart to beat rhythmically and autonomously, although the autonomic nervous system can modulate the heart rate and contraction strength.
What do muscles do list two different functions of muscles?
Some muscles (skeletal muscles) will not contract unless stimulated by neurons; other muscles (smooth & cardiac) will contract without nervous stimulation but their contraction can be influenced by the nervous system. Thus, the nervous and muscle systems are closely interconnected.
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.
Weak stimulation of a motor neuron causes the muscle to what?
contract weakly
Does skeletal muscle need stimulation to contract?
Yes! Although we have total control over these muscles, they still need stimulation to contract. The difference with muscles that we don't control is that we decide if we want to make this stimulation.
What are smooth muscle contractions?

How do muscles work independently?
it depends on how you use them like it you curl your arm that will be the biceps working alone but if you bench press the triceps and pectoralis muscles work together
What can the nervous system do to increase muscle tension?
The nervous system can increase muscle tension through the recruitment of motor units and the frequency of action potentials sent to the muscles. When more motor neurons are activated, additional muscle fibers contract, leading to greater force production. Additionally, increasing the rate of stimulation (temporal summation) can enhance muscle tension by allowing muscle fibers to contract more forcefully before they have a chance to relax. This coordinated control allows for precise adjustments in muscle tension to meet various demands.
