What else can I help you with?
Impulses from motor neurons control the contraction of skeletal muscles?
false
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 qualities do cardiac and skeletal muscles share?
Cardiac and skeletal muscles are both striated muscles that contract in response to nerve impulses. They contain sarcomeres as their basic contractile unit and rely on the presence of calcium ions for muscle contraction. Additionally, both types of muscles are composed of muscle fibers that vary in size and length.
Do skeletal muscles have involuntary muscle?
The skeletal muscles do have the involuntary muscle because they help it in the contraction process.
What muscles are straited?
smooth skeletal cardiac and contraction mbroro
What proteins help contraction of skeletal muscles?
Actin and myosin cause muscles to contract.
What division transmits impulses from the cns to the muscles or glands?
The sensory or afferent division of the peripheral nervous system transmits impulses from the sense organs to the CNS.
What makes our skeleton?
the contraction of our muscles which are contracted by neurones carrying impulses from the brain
A test using inserted needles to measure nerve impulses?
Electromyography.Electromyography measures the electrical impulses of muscles at rest and during contraction.
Which of these parts receive nerve impulses?
dendrites receive electrical and chemical signals from axon terminals.
Do muscles push or pull when they contract?
pullThey pull on connective tissue sheaths of skeletal muscles which transmits pulling force to the bone to be move.
Do motor neurons send impulses to muscles or glands?
Motor neurons send impulses to muscles to stimulate muscle contraction. Glands are typically innervated by autonomic neurons that regulate secretions like hormones and enzymes.
