Blood brings oxygen and ATP, which react with one another (oxidation), to the muscle cells. The result of this oxidation process (aerobic) is energy and heat. (Most of the body's heat originates from muscle activity.)
Skeletal muscles will not contract unless stimulated by neurons.
What else can I help you with?
Where do muscles get the energy they need to do work?
The energy is produced through an aerobic process called oxidative phosphorylation. About 60% of energy comes from fatty acids and triglycerides and 35% from carbohydrates. The remaining 5% is from amino acids and ketone bodies. The oxidation is supported by myoglobins that store oxygen in the muscle.
What one of these occurs wherever we need to move our bones?
Muscles. They contract and relax to allow movement of our bones.
Why do ligaments need to stretch much more than tendon?
Ligaments connect bones to bones and need to stretch more than tendons, which connect muscles to bones, because they are responsible for stabilizing joints and allowing a greater range of motion. Tendons need less flexibility as their main function is to transmit force from muscles to bones to facilitate movement.
Why do muscles require more energy even when they are not very active at the moment?
Muscles require more energy even when they are not very active because they need a baseline level of energy to maintain their structure and function, such as maintaining muscle tone and readiness to contract when needed. This baseline energy consumption is known as the basal metabolic rate of muscles.
Why do muscles need to act as antagonistic pairs?
Muscles need to act as antagonistic pairs to create movement at a joint. One muscle contracts (agonist) to produce the desired movement, while the opposing muscle relaxes (antagonist) to allow the movement to occur smoothly and efficiently. This coordinated action helps stabilize the joint and prevent injury.
Why do cardiac muscles have a better capillary network than skeletal muscles?
Cardiac muscle have a greater need for oxygen than skeletal muscles because they use up more energy in a shorter amount of time so they require regular refills of oxygen.
What are muscles skeletal cardiac and smooth?
smooth muscle is used in a train of thought (brain is need in the act) cardiac muscle can be found in the heart skeletal muscle moves your bones
What is steady exercise in which the heart can supply all the oxygen the muscles need?
Aerobic exercise
Explain why the skeletal and muscular systems cannot function without each other.?
We need all 11 of our body systems in order to function. Muscular system provides ligaments, tendons, and muscles to make the bones attach muscles. Without the skeletal system, our body will not have any support. Without muscular system, we'll just look like a skeleton covered with skin. Also there are blood vessels and nerves in the muscles, and that's how we move and use our feet and hands.
Why ligaments a part of the skeletal system?
If we didn't have a skeletal system we would be a blob on the ground. If we didn't have bones well basically the same thing but also we wouldn't be able to produce blood or marrow.<----- (important) We also need tendons and ligaments so our muscles stay attached to our bones (another reason why we need bones) and allow smoother movement.
What would happen if part of your skeletal system was removed?
Since muscles need bones to work on, we would not be able to move or do other functions.
Why must skeletal work in pairs to move a bone?
Skeletal muscles work in pairs to move a bone so that the muscles can function properly. Muscles can only pull, therefore bones need two muscles to make it move. To put a finger up one muscle might pull, the other will put to put back down. With two, the movement will be smooth, otherwise it will be "jerky" and uncontrolled.
Why is it important that muscular system be nourished by the blood on a priority basis?
It is important that muscular system be nourished by the blood on a priority basis. This is because the muscles are constantly using energy and need to be nourished and have the energy replaced.
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 does the skeletal system do to meet the cells need?
The skeletal system meet the cells need by .....

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.
