If A nerve impulse travels through your nervous system at an avg rate of 132 m per s How much time does it take for an impulse a distance of 1.49 m to reach your brain?
11 mS
How does equilibrium information reach the brain?
The information of the equilibrium reach your brain via vestibulocochlear nerve. It is the eighth cranial nerve.
Can part of the impulse in a reflex action reach the brain?
because it is the cells
When your nose is stuffy cannot reach nerve receptors to initiate an impulse that would result in smell or taste?
chemicals
1 List the physiological events that occur between delivery of the stimulus and the start of the recorded response?
The speed of nerve impulse transmission changes as the body ages. In infants, the transmission speed is only about half that seen in adults. By age five, most people have attained the adult velocity. A gradual decline in conduction velocity begins as people reach their 20s, and continues for the remainder of life. Another factor that influences conduction velocity is the length of the nerve itself. An impulse that has to travel a longer distance will take longer. Some nerves are naturally longer than others. Measurement of nerve conduction takes into account the length of the target nerve. Some other factors are: · Initiation of action potential in nerve fibers; · Conduction of impulse; · Release of acetylcholine from the nerve terminals; · Binding of acetylcholine to receptors of the motor end plate; · Depolarization of the end plate; · Initiation of action potential in muscle fibers; · Muscle contraction.
What is the difference between nerve and neuron?
A neuron is an individual cell in the PNS or CNS that can be excited and conduct impulses along its axon. A nerve is a bundle of multiple neuron fibers that each are carrying their own signals. They are protected by connective tissue. Eventually the neuron fibers diverge away from the nerve to reach their destination.
What role does the nerve cord inside of the vertebrate play in the body?
It allows nerve signals, such as pain, to reach your brain from various parts of your body.
What type of nerve is the auditory nerve?
In the inner ear, "sound" is translated into electrical energy. This electrical energy is transmitted to the brain via the 8th cranial nerve more commonly called the auditory, acoustic or vestibulocochlear nerve. The brain receives the information and translates it into what we "hear", or at least into what is most important for us to hear at that time.
A nerve impulse that originates in the precentral gyrus of the cerebrum?
A nerve impulse that originates in the precentral gyrus of the cerebrum is responsible for initiating voluntary muscle movements. It travels along the corticospinal tract, crosses over to the opposite side of the brainstem, and descends through the spinal cord to reach the muscles that are involved in the intended movement. This process allows for precise and coordinated control of voluntary movements throughout the body.
Where are messages interpreted in the brain?
In most cases signals are sent to the brain through the nervous system. Individual signals are transfer from neuron to neuron in the form of chemical and electrical energy that eventually reach the brain.
How would severing the sympathetic nerves to legs help with pain?
Severing the nerve blocks the ability of pain signals to reach the brain. Therefore, the brain can not sense pain.
What is a vestibular neurectomy?
A vestibular neurectomy is a procedure where this nerve is cut so the distorted impulses causing dizziness no longer reach the brain.
