i think its the brain...
What else can I help you with?
In some reflex actions skeletal muscles contract without the involvement of what?
In some reflex actions, skeletal muscles contract without the involvement of conscious thought or decision-making processes from the brain. These reflex actions are controlled by the spinal cord and are known as spinal reflexes.
Without what can skeletal muscles contract in some reflex actions?
the brain.
Are your leg muscles smooth muscles?
No, the muscles in your leg are skeletal muscles. Smooth muscle is found for example in vessels and the gastrointistinal tract. Yes smooth muscles are involuntary, which means they contract and relax without our conscious decision for them to do so, however we have control over when we want to move our leg muscles, so it cannot be smooth muscle, they are as said before my answer, quite rightly, skeletal muscles
What muscle actions would be classified as an isometric contraction?
1. We can isometrically contract any skeletal muscle of our body. We can contract just one skeletal muscle of the body without contracting any other.However, we should be masters of Original Meditation to be able to put the small muscles of the head into pure isometric contraction. These are muscles of face, muscles within the oral cavity, muscles in front of the neck, those around eye ball and those in the middle ear.2. We can Isometrically contract and relax all the skeletal muscles of the body as a single unit.
Which joint in the body allow movement to be produced by the skeletal muscle?
all four of the joints are moved by skeletal muscles without skeletal muscles joints wouldn't move
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.
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.
How are voluntary and involuntary muscle different from each other?
Generally, voluntary muscles are striated and skeletal muscles, while involuntary muscles are smooth muscles and are visceral (located in organs). Voluntary muscles are muscles that can be consciously contracted, while involuntary muscles are muscles that are contracted at certain times or at all times without the conscious consent of the brain.
How do the skeletal and muscular systems work to move the body?
The skeletal system works as the support system, holding you in shape and upright. The muscles are attached to the skeletal system using contractions and relaxation of the muscles to pull and move the bones.
Are nerves needed for muscles to contract?
Yes, without the nerves the muscles would be rendered useless. The muscles MUST have stimulation from somehwere in order to contract.
What organ has involuntary and striated muscles?
The heart as both involuntary and striated muscles. The striations are similar skeletal muscles. Heart muscles are involuntary like the muscles seen in the digestive tract, called smooth muscle.
What would happen if the skeletal muscels were not there?
If skeletal muscles were not present, the body would not be able to move or maintain posture. Skeletal muscles enable us to perform voluntary movements like walking, running, and lifting objects. Without skeletal muscles, activities that involve movement would not be possible.
