What else can I help you with?
Why does tetradotoxin lead to death?
It blocks the channel for sodium on the sceletal muscle and inhibits therefor the transmission of electrical impulses that are necessary for muscle contraction
What minerals are needed for muscle contraction and conduction of nerve impulses?
Minerals such as calcium, magnesium, sodium, and potassium are essential for muscle contraction and nerve impulse conduction. Calcium is particularly important for initiating muscle contractions and transmitting nerve impulses, while magnesium, sodium, and potassium help regulate muscle relaxation and contraction as well as nerve impulse transmission.
Impulses from motor neurons control the contraction of skeletal muscles?
false
What allow the nerve impulses that initiate muscle contraction to travel along the sarcolmena?
Nerve impulses initiate muscle contraction by traveling along the sarcolemma through a process called depolarization. When a nerve impulse reaches the neuromuscular junction, it releases neurotransmitters that bind to receptors on the sarcolemma, leading to a change in membrane potential. This depolarization creates an action potential that propagates along the sarcolemma and into the T-tubules, allowing the signal to reach the muscle fibers and trigger contraction. Additionally, the presence of voltage-gated sodium channels facilitates the rapid transmission of these impulses.
A test using inserted needles to measure nerve impulses?
Electromyography.Electromyography measures the electrical impulses of muscles at rest and during contraction.
What kinds of compounds in the body transmit impulses between nerve and muscle cells?
Neurotransmitters such as acetylcholine transmit impulses between nerve and muscle cells. These chemical messengers are released at the synapse where nerve and muscle cells meet, allowing for the transmission of signals that trigger muscle contraction.
What makes our skeleton?
the contraction of our muscles which are contracted by neurones carrying impulses from the brain
What is the tissue that directs how and when muscles move?
The nervous system, specifically the brain and spinal cord, directs how and when muscles move through the transmission of electrical signals called nerve impulses. These impulses travel along motor neurons from the central nervous system to the muscles, triggering muscle contraction and movement.
Muscle contraction is triggered by impulses carried over what?
when ATP attaches to the myosin heah
What major mineral is required for transmission of nerve impulses?
neuro transmitter is essential for the transmission of nerve impulses in nerve fibres.it is a chemical which is present in the axon terminal bulb(ending of a neuron).
Cardiac muscle fibers electrically connect to neighboring fibers by?
intercalated discs, which contain gap junctions that allow for the rapid transmission of electrical impulses between cells. This ensures synchronized contraction of the heart muscle.
Which Mineral is necessary for transmission of nerve impulses in the nerve fibers?
Zinc
