What nerve is also known as the acoustic or auditory nerve?
The nerve that is also known as the acoustic or auditory nerve is the vestibulocochlear nerve (cranial nerve VIII). It is responsible for transmitting auditory and balance information from the inner ear to the brain.
Is the optic nerve a single nerve or a bunch of nerves connected?
It is a bundle of neurons, all flowing from the same general source (the eye) to the optic chiasm.
What is the process where sensory receptors become less sensitive to the same stimuli?
You can think of what happens when you smell things that are usually the same day to day. You will notice that smell less and less. Olfactory fatigue is an example of neural adaptation or sensory adaptation. The body becomes desensitized to stimuli to prevent the overloading of the nervous system, thus allowing it to respond to new stimuli that are out of the ordinary or new.
Can there be smaller or larger nerve impulses?
Nothing stays the same, right? The answer is, of course.
Is ctyolasm the same thing as plastid?
No, the Chloroplast is the same thing as the plastid.
What is the same as a sensory nerve?
The peripheral nervous system is the same as the sensory nerves. These are the nerves which are responsible for the various senses.
Are effernet nerve fibers described as motor nerve fibers?
Yes, remember the mnemonic SAME DAVESAME DAVE:sensory is afferent, motor is efferentdorsal is afferent, ventral is efferent
What are sensory receptors?
A sensory receptor is a sensory nerve ending that responds to a stimulus in the internal or external environment of an organism. The sensory receptor initiates sensory transduction by creating graded potentials or action potentials in the same cell or in an adjacent one.
What is the difference between foot drop due to sciatic nerve injury and common peroneal nerve injury?
no difference except for the sensory supply. if you damage your sciatic nerve, the sensory and muscle supply above the knee also lost as the sciatic nerve is damage. This is because common peroneal nerve is the brach of sciatic and it is at level of your knee. Only muscle and sensory below the knee level will be affected if you damage the common peroneal nerve. However the condition of foot drop would be the same
Are neurons and nerve cells different name for the same thing?
True
Can atomic neurons be sensory or afferent neurons?
I believe you mean autonomic neurons (part of the ANS) and yes, they can be sensory neurons. Sensory neurons are the same as afferent neurons--meaning they carry signals towards the CNS. Think as afferent as 'approaching'. Anyhow, these neurons sense the conditions of your visceral organs and whatnot. Other wise it would have no information to judge for what signals to send. So yes, autonomic neurons consist of both sensory (afferent) and motor (efferent) neurons.
What is the definition of sensory?
1. relating to sensation and the sense organs - "heightened sensory awareness" 2. involving or derived from the senses 3. connected with the physical senses of touch, smell, taste, hearing and seeing 4. of, pertaining to, or transmitting stimuli to the senses. 5. conveying nerve impulses from the sense organs to the nerve centers - "sensory neurons" In medieval cultures, literature as communicative action is at all times also physical and sensory action. Emotional poetry by early writers in United States continued in the same lines.
Which of the following types of neurons carries impulses away from the CNS?
They are called as motor neurons. They are same like sensory neurons. Only difference the direction of the nerve impulse. The nerve impulse travel from dendrites to body to axon to axon terminals.
Does the cerebral and basal ganglia is same?
Not really. Basal ganglia are a grouping of nerve cell bodies that are associated with various parts of the brain, mostly for sensory input, and one of these associations is the cerbrum.
Can a nerve fibre and nerve both carry sensory and motor impulses?
There are the Mixed Nerves in the spinal column that carry both sensory and motor nerves, but these neurons have 2 different jobs that they do,& I know of no neurons doing both as the impulses travel to 2 different locations which couldn't be done at the same time.
What happens when the serpentine belt breaks?
The same thing that happens when you cut the Jugular, its like the main nerve in a car!
What are afferent and efferent neurons and inter neurons?
These neurons are classified by the direction in which they send their messages. Afferent neurons are typically sensory neurons--neurons which send information to the brain and spine. They send information about the body and immediate environment. Efferent neurons are typically motor neurons, sending information from the brain and spine to the rest of the body. They allow the main control system a way to act on the body. Another way to distinguish these two is to think of afferent nerves as 'approaching' the brain (A) and efferent nerves as 'exiting' the brain (E). Interneurons are relay neurons and their signals, connecting efferent and afferent neurons in network. They can link up the same types or different types of neurons, meaning connecting sensory neurons together, motor neurons together, or the different types together. The simplest example of these three types working in unison is a reflex arc (which is what is activated when you hurt yourself, like stepping on a pin or burning your hand). The sensory/afferent neuron detects pain and signals the interneuron. Simultaneously, the interneuron sends a signal to your efferent/motor neurons to retract your hand/leg/whatever, while also sending a message to the brain. This is why you pull back before you feel pain :).
