Answer:

c. saltatory conduction

Explanation:

An electrical impulse begins at the upper end of the neuron. This area is known as the axon ridge, and this ensures that the electrical impulse will travel in one direction only.

Through the myelin, the electrical impulse jumps from one node to another, instead of having to travel the entire distance from the axon. This type of signal conduction is called saltatory conduction.

Saltatory conduction speeds up impulse movement, as some axons may be up to one meter long. With this, the body achieves fast and efficient nerve conduction, and it is what allows you to react so quickly during reflexes.

Origin: In biology, origin can be described as the location where the muscle joins a stationary bone and as a result, no movement occurs.

Insertion: In anatomy, insertion can be described as the point of attachment which allows movement of a bone to occur. It moves when the muscles contract.

Tendon: In biology, the tendon can be described as a type of connective tissue which attaches a bone to a muscle.
