Skeletal and smooth muscles move when nerve impulses sent from the stimulate the muscle fibers telling them to either contract or relax?
Skeletal and smooth muscles contract or relax in response to nerve impulses that stimulate their muscle fibers. In skeletal muscles, motor neurons release neurotransmitters at the neuromuscular junction, triggering contractions. Smooth muscles, which are involuntary, respond to autonomic nervous system signals and various hormones. This process allows for coordinated movements and functions throughout the body.
Skeletal and smooth muscles move when nerve impulses sent from the blank stimulate the muscle fibers telling them to either contract or relax?
Skeletal and smooth muscles move when nerve impulses sent from the nervous system stimulate the muscle fibers, instructing them to either contract or relax. In skeletal muscles, this stimulation comes from motor neurons, while smooth muscle contraction is typically regulated by autonomic nerve fibers. These signals trigger a series of biochemical events that lead to muscle contraction and relaxation.
What do the nerves carry to the muscles?
Electrical impulses telling them to contract or relax.
What organs are needed to make the muscular system work?
You need your brain to send signals to a skeletal muscle telling it to contract.
What role do nerves play in skeletal contraction?
When you think about moving your arm, your brain sends a signal down a nerve cell telling that muscle to contract. -
What are Most active muscle in the body?
what is the most active muscle in the body thats not telling the answer stupid someone wants to know the answer to it what you said was the ? not the answer stupid
Why can you bend your arms?
When you bend your arm your brain send signals to your arm muscles telling the biceps, your upper arm muscles, to contract, go taut or stretch, while telling your triceps, lower arm muscles, to relax, become less tense or ease. Both of these muscles act as an antagonistic pair and work together to bend the arm. Each muscle uses the bones in your arm, the Humerus, the ulna and the radius, as an anchor.MonkeyLover-Dinda
Is the muscle movement inthe human body an example of biology?
yes, the muscles in the human body are the effect of what are brain is telling us to do, the muscles will either contract or loosen according to what the brain has sent. All of this would come under the topic of Biology.
What does muscles do for me?
make your body move and function. The Brain sends electrical pulses to a certain part of the body telling the muscle to contract, then you move. Your brain cant type on a key board, but it can tell your hands to.
What body systems are involved in jumping up and down?
The instinctual "fight or flight" response. The hormone adrenaline is released from the adrenal glands, which stimulate your muscles giving an instantaneous (But temporary) boost of energy, which can be used to combat or flee from whatever threat may have startled you.
Does the nervous system have a relationship with a different organ system?
Yes. It is related to other organ systems. For example, the nerves are related to the digestive system, because they carry the messages telling you you're hungry or full (etc.). The nerves are related to the musculature, because they carry the messages telling the muscles to contract or relax. The nerves are related to the circulatory system, since through their conveying sensations of heat or cold, they cause and carry the messages telling the arterioles to expand or contract. And so on.
How are your hands able to move?
My hands are able to move due to the complex coordination of muscles, tendons, and nerves in my body. Signals from my brain are sent through my nervous system to the muscles in my hands, telling them to contract or relax in order to move them in a desired way. This intricate process allows for precise and controlled movements of my hands.
