Why are electrolytes important to athletes?
Electrolytes are important to athletes because they help maintain proper fluid balance in the body, regulate muscle function, and support nerve function. During physical activity, electrolytes like sodium and potassium are lost through sweat, so replenishing them is crucial to prevent dehydration, muscle cramps, and fatigue.
Communication in the nervous system depends on?
action potentials
Does nervous tissue generate action potentials?
Yes.
What substance excites the nervous system?
The nervous system responds to stimuli, that is referred to as excitability. The chemicals that are involved in carrying the impulse from being excited are called neurotransmitters.
What is the fucntion of a nerve cell?
the transport of nervous impulses ( also known as action potentials)
What does communication in the nervous system depend on which are electrical impulses that travel from neuron to neuron?
action potentials
How is information processed and transmitted in the nervous system?
It is transmitted along action potentials by way of chemical neurotransmitters.
What are the electrolytes in the body and what are their roles in the body?
they help your cardiovascular system and your nervous systems function
What does the central nervous system use to determine the strength of a stimulus?
frequncy of action poteinals
How do action potentials relay intensities of information?
The nervous system can detect the strength of a stimulus by measuring the frequency of action potentials . For example a hard hit might generate 10 impulses per second.
What are the two subdivisions of the motor subdivision of the peripheral nervous system?
The two subdivisions of the motor subdivision are the somatic nervous system and the autonomic nervous system. The somatic nervous system transmits action potentials from the CNS to skeletal muscle, and the autonomic nervous system transmits action potentials from the CNS to smooth muscle, cardiac muscle, and glands.
What is a tonic current?
Not all the electrical signalling in the nervous system is by way of action potentials, or impulses. Indeed it could be argued that some of the most important, if not the most important, of the central nervous system's communications depend upon non-impulse signalling. These signals, which are at least one order of magnitude and sometimes two or more orders of magnitude, weaker than action potentials have been termed electrotonic potentials. They are small depolarisations of a nerve process's membrane and are caused by the essentially passive spread of electrical current through the conducting fluids inside and outside nerve cells and their processes. Nonetheless, however small electrotonic potentials may be, they can have very considerable effect on the physiology of neuronal membranes and thus on the large-scale functioning of the brain. cited from - Elements of Molecular Neurobiology 3rd ed C.
