Describe the path a nerve impulse travels throughout your body from stimulus to response?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineAcetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
What is the medical term meaning nerve pain through the thigh and leg?
The medical term for nerve pain through the thigh and leg is "sciatica." Sciatica is characterized by pain, tingling, or numbness that radiates along the path of the sciatic nerve, which runs from the lower back down the back of each leg. It is often caused by compression or irritation of the nerve roots in the lower spine.
Would conduction speed of a nerve fiber be the fastest in a large or small myelinated fiber?
The conduction speed of a nerve fiber is fastest in large myelinated fibers. This is because myelin acts as an insulator, allowing for faster propagation of the action potential by saltatory conduction in large fibers compared to small unmyelinated fibers.
What are the nerves that pass the elbow?
The three main nerves that pass the elbow are the ulnar nerve, the median nerve, and the radial nerve. They are responsible for providing sensation and motor function to different parts of the arm and hand. Each nerve follows a different path through the elbow to reach its respective destinations.
How does the shape of a nerve cell aid in its function?
The nerve cell's thin and dainty shape helps it transmit signals. Also, the "fingers" at the ends help transmit the messages to more than one other nerve cell so the message can reach either the brain or the spinal cord faster. The thin shape also helps keep the message on a straight path and keeps the message from getting confused or mixed up with other messages being transmitted so as to insure the direct and immediate receiving of all the messages. 👍👍👍

Can nausea be caused from a pinched nerve in the cervical spine?
Yes. Nausea can be caused by entrapment or irritation of the vagus nerve which itself travels a long meandering path from the brain to deep within the gut.
Which statement correctly describes the path that an electrical impulse would take after someone touched a hot pot?
The signal travels though the nerve endings in the hand to the spinal cord. From there, it reaches the brain and in less than one second, your body realizes the pot is hot, causing you to react by quickly removing your hand from the hot pot.

Describe the path a nerve impulse travels through?
When an impulse travels to the brain, it is first received by sensory receptors, then sent through the neurons by an electrical current. When the neuron receives the signal from a sensory receptor or from another neuron, the nucleus processes the impulse and then sends it down the axon. When a neuron is resting, the inside of the cell has a negative charge caused by active transport of NA and K molecules. This is called the resting potential. When the impulse hits the axon, the electricity causes NA pumps to open, allowing a flow of positively charged the molecule into the cell, causing the charges to switch. This is called the action potential. As the impulse passes, the K pumps open, restoring the original charge. When the impulse reached the end of the axon, neurotransmitters chemically pass the impulse to the next neuron. ;
What carries electrical impulses from the ear to the brain?
The auditory nerve carries electrical impulses from the ear to the brain. It connects the hair cells in the cochlea of the inner ear to the brainstem, allowing sound signals to be transmitted and interpreted by the brain.
Can you and if you can have shingles on the head will they be only on one side or can they be at the back of the head or base of neck?
Anywhere! Shingles follow the path of a nerve.
Why transmission at chemical synapses is unidirectional and why is it significant?
ok why is it uni directional. because there are only the receptors for the neurotransmitter on the receiving dendrites and not on the terminating bud. this means that the sodium can only be absorbed into the next nerve cell/brain cell in the line. but sodium released in a nerve impulse that is not absorbed into the next cell is asimilated back into the original terminating bud for reuse.as for why this is important. im speculating here but it means that the impulse can only go down the intended path and cannot go backwards in the chain.*addition*Uni-directionality is a function of the asymmetry of the synaptic cleft. Exocytosis of the neurotransmitter only occurs from the presynaptic terminal and is received at the postsynaptic receptors to cause initiation of the next impulse (Ca++ carried in dendrons). Although there are receptors on the presynaptic membrane, these are not depolarizing but inhibit further neurotransmitter release. Since the postsynaptic membrane does not release neurotransmitters and the receptors on the presynaptic membrane (auto-receptors) are not depolarising, the impulse is not back propagated.Uni-directionality of the impulse also occurs due to the characteristic membrane potential changes caused by the action potential. The hyper-polarisation of the nerve section caused by K+ efflux (repolarising and then hyper-polarising the nerve as the channels are slow to close), allows for the resetting of Na+ channels. This period (and slightly beforehand when the Na+ channels inactivate) is called the refractory period. Not only does this stop another impulse passing along the neurone, but the impulse can not pass backwards either. NB: local currents in nerves will travel in both directions, but since the previous section of the nerve has inactivated Na+ channels and is undergoing a period of hyper-polarisation, the impulse will not be back propagated.Uni-directionality is crucial to allow for the transmission of discrete impulses that can be interpreted by the brain as signals rather than an entire nerve depolarisation (which is not an impulse at all).So:Uni-directionality due to:asymmetry of cleftNa+ inactivationK+ efflux hyperpolarisationUni-directionality important because:allows for discrete impulses
