A nerve can stimulate impulses to several muscle fibers. When muscle fibers are grouped they form a single muscle group like the biceps.
What else can I help you with?
The most rapid nerve impulses are impulses that are carried?
The most rapid nerve impulses are carried by myelinated nerve fibers, which have a fatty sheath called myelin that enables faster signal transmission. These fast nerve impulses are crucial for quick reflex actions and communication between different parts of the body. Unmyelinated fibers are slower in transmitting nerve impulses compared to myelinated fibers.
The point of contact between the nerve and the muscle fibers it stimulates is called a?
The point of contact between the nerve and the muscle fibers it stimulates is called a neuromuscular junction. This junction allows for communication between the nervous system and the muscular system, facilitating muscle contraction in response to nerve impulses.
Which of these parts receive nerve impulses from the central nerous system causing muscle fibers to contract?
The motor neurons carry impulses from the central nervous system to the muscles. These impulses may be generated autonomically (instinctively) or through voluntary control by the brain.
Do converging nerve fibers amplify nerve impulses?
Converging nerve fibers do not amplify nerve impulses. Instead, they may integrate inputs from multiple sources and help to summate signals to generate a stronger overall signal that can lead to an action potential being generated.
What muscle and nerve will you need to isolate to study the physiology of nerve fibers?
To study the physiology of nerve fibers, you would need to isolate a specific muscle and the nerve innervating that muscle. This allows for the investigation of the interaction between the nerve and muscle, observing the transmission of signals and studying the response of the muscle to nerve stimulation. Commonly studied muscles and nerves in this context include the gastrocnemius muscle and the sciatic nerve in animal models.
Muscle fibers contract and relax in response to what?
nerve impulses
Which nerve fiber do impulses travel slowly?
Unmyelinated nerve fibers conduct impulses more slowly than myelinated nerve fibers. Myelinated nerve fibers have a fatty substance called myelin sheath that allows for faster transmission of impulses compared to unmyelinated fibers without this sheath.

Which Mineral is necessary for transmission of nerve impulses in the nerve fibers?
Zinc
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 part in the human body receives nerve impulses from the central nervous system that causes muscle fibers to contract?
Motor Neurons.
The point of contact between the nerve and the muscle fibers it stimulates is called a?
The point of contact between the nerve and the muscle fibers it stimulates is called a neuromuscular junction. This junction allows for communication between the nervous system and the muscular system, facilitating muscle contraction in response to nerve impulses.

What carries odor impulses to the cerebrum for interpretation?
nerve fibers?
Is it true that motor neurons receive nerve impulses from the central nervous system causing muscle fibers to contract?
It would be more accurate to say that the neurons transmit the impulses, rather than that they receive them.
Do converging nerve fibers amplify nerve impulses?
Converging nerve fibers do not amplify nerve impulses. Instead, they may integrate inputs from multiple sources and help to summate signals to generate a stronger overall signal that can lead to an action potential being generated.
How fast nerve impulses travel?
Nerve impulses travel through nerve fibers, and the speed of which they travel depends on the type of nerve fiber. They travel usually around 86 miles per hour.
