This can be caused by inhibitor molecules known as neurotoxins occupying the active sites of the receptor molecules of the postsynaptic neurone membrane, this prevents an action potential from being carried from the presynaptic neurone to the postsynaptic neurone, thus preventing the passage of a nerve impulse and consequental muscular contractions that produce an effect to stimuli

What is the adaptive advantage of faster conduction of nerve impulses?
Faster conduction of nerve impulses allows for quicker responses to stimuli, which can be crucial for survival in situations that require rapid decision-making or action. This adaptation enhances an organism's ability to react to potential threats or opportunities in the environment, improving its chances of survival and reproductive success.
Path way of the message to the nervous system?
The stimuli will be picked up by the sensory neurons then nerve impulses travel to your spinal cord. Those nerve impulses return to motor neurons that will react (like you pull your hand away, or you yell) as you react the nerve impulses travel to your brain.
What are the two ways main ways in which neurons are able to react stimuli?
Nerves receive signals meaning that they can respond to a stimulus. Once a stimulus is received by a nerve cell it converts it to a neural impulse which passes along the nerve. Nerves are able to transmit impulses along the length of the nerve cell in the form of an electrical signal.
What muscles react very quickly?
Skeletal muscles react very quickly of all three muscle type, probably.
How do the notochord and nerve chord and backbone help an organism to move around?
well it depends on where the organism starts but usually the organism will be around the shoulder blade and then be pished to the spine by the neck muscles. when the organism reaches the spine, the larjdick then vibrates forcing the organism down to the arcerooter causing a reaction in the notochord wich is the start of the process of moving the organism around. the nervr chord and bachbone react and relate to the movement of the notochord thus moving the organism.
Which muscle trait is the ability to respond to a stimulus such as a nerve or hormone?
Muscle excitability is the ability to respond to a stimulus, such as a nerve signal or hormone, by generating an electrical impulse that leads to muscle contraction. This trait allows muscles to react to signals from the nervous or endocrine systems to produce movement.
What does the tissues responsible for sensing stimuli?
The tissues responsible for sensing stimuli are called sensory receptors. These receptors are specialized cells that detect changes in the environment, such as pressure, temperature, and chemicals, and convert them into electrical signals that can be interpreted by the brain. Various types of sensory receptors are found throughout the body, including in the skin, eyes, ears, and internal organs.
Is the following sentence true or false skeletal muscles react quickly and tire easily?
its false... skeletal muscles cannot react quickly and they don't tire easily...
What are the nerve cells that react to gases?
Olfactory receptor neurons are nerve cells that react to gases, specifically in the context of the sense of smell. These neurons are located in the olfactory epithelium in the nasal cavity and are responsible for detecting various odors in the environment.
How might smooth muscles react slowly and tire slowly be an advantage for smooth muscles?
it makes it tight
What is the weakest nerve in the body?
There is not a weakest nerve in the body. All nerves react the same to stimuli granted the stimuli is strong enough.
What is a neroun that carries impulses away from the central nervous system to the body parts that react?
They are called as motor neurons.
