What does contractile impulse mean?
Contractile impulse refers to the electrical signal that initiates contraction in muscle cells. In cardiac muscle, this impulse originates from the sinoatrial (SA) node, propagating through the heart to coordinate rhythmic contractions. In skeletal muscle, it results from signals transmitted by motor neurons. Overall, contractile impulses are crucial for the effective functioning of both cardiac and skeletal muscles.
Substance released at axonal endings to stimulate a nervous impulse is?
a neurotransmitter
Where do nerve impulses first stimulate a skeletal muscle fiber?
The motor nerve cells control the skeletal muscle
What is a nerve impule transmitted by axons?
It is called a nerve impulse.
How does a single nerve impulse initiate many?
The nerve's endings are near to other nerve endings, when the potential of the potassium ion that is released is sensed by the other nerves they all might send an impulse to their other ends and the situation could be repeated.
What is Converging Circuit?
a neural curcuit in which a single impulse is transmitted over and over is a?
What is the location from which a nerve impulse is transmitted from one nerve cell to another?
synapse
What is the brief electrical impulse transmitted along the axon called?
Butter Steak.
Also called a nerve impulse transmitted by axons?
action potential
The reabsorption of a neurotransmitter after it has transmitted a neural impulse is called?
Reuptake
The greater the amount of coating the axon the faster the nerve impulse will be transmitted to the synapse?
myelin
What is the period of time after a nerve impulse has been transmitted when it is not possible for another impulse to act upon the dendrite and the axon?
The Resting Period; over with in less than milliseconds.
