![]() Nerve impulses are created due to some of the characteristic properties of the nerve fibers, such as excitability, all or none rule, differential permeability, and conductivity. The neural membrane is referred to as the membrane surrounding the neurons. The process of action potential occurs when there is a threshold stimulus. The neural membrane has several kinds of ion channels. Nerve fibers help in the conduction of nerve impulses in the human body. ![]() Myofilaments overlap in sarcomere, which is the unit of muscle fiber. In the muscle, the maximum force production takes place because of the presence of interlaced myofilaments. These tendons control the constant level of the stretch called the resting length. Skeletal muscles normally remain linked to the cartilage and bone through the assistance of tendons. The muscles of human beings are elastic due to the presence of titin in muscles. In the same way, contraction and relaxation follow these rules for muscles of the body. When the stimulus is high, depolarization in the nerve impulses takes place and the signals in the axon can be sent towards the axon of the nerve cell. This rule is non-dependent on the intensity of the stimulus. A response can be generated from this single nerve fiber as per this rule. The shock generated by nerves and muscles gives rise to contraction. The conduction of nerve impulses in the body occurs in three stages, namely, the resting potential, action potential (also known as depolarization), and repolarisation. It is helpful in the generation of nerve impulses through axons. The all or nothing principle is the generation of the response depending on the stimulus.
