Does a efferent neuron convey information away from the hippocampus?
Technically efferent neurons carry information AWAY from anything, afferent neurons carry information TOWARD something. So the hippocampus may have efferent information going to other parts of the brain (limbic structures, frontal lobe structures, etc). Most often efferent information refers to motor output in or to the peripheral nervous system.
What is the most abundant class of neuron in the central nervous system?
multipolar
The most common type of neuron found in the central nervous?
I know that sensory neurons are a type of nervous tissue in the nervous system.
What structure insulates neurons?
Myelin Sheath is the structure that insulates most part of neuron
What is the shape of the sensory neuron?
The sensory neurons in our body have different shapes but most are unipolar-shaped. Neurons can either be unipolar-, bipolar- or multiparty-shaped depending on their function.

Is the sensory neuron multipolar?
No, they (sensory neurons) are either pseudounipolar or bipolar.To memorize, remember the word "M" for Multi-unipolar, and "M" for "Motor" (fibres).
What is the correct order of components of a reflex arc?
The three-neuron arc is the most common and consists of the afferent neurons, interneurons, and the efferent neurons. Afferent neurons conduct impulses to the CNS from the receptors. Efferent neurons conduct impulses from the CNS to effectors (muscle or glandular tissue). Two-neuron arc is the simplest form, fastest responding and consists of afferent and efferent neurons. Example is the knee-jerk reflex.
What neurons are most abundant in the central nervous system?
98.8%
Are all the efferent neurons motor all the afferent neurons sensory and all the CNS neurons inter neurons?
Yes. However, it is better put that most of the interneurons are found in the part of the CNS called the spinal cord.
What part of the neuron receives most of the incoming signals from other neurons?
dendrite

What does motor nuerons do?
Ultimately a motor neuron is involved in the pathway of sending information from your brain to your muscles, thus allowing your brain to control the movements of your body. As an analogy, think of your computer and the printer to which it is attached. The computer is your brain, the printer is the muscle that needs to perform an action, and the cable connecting the two is the motor neuron.A neuron is a cell in the central nervous system that has a cell body and a very long extension called an axon. There are two levels of motor neurons in your body, the upper motor neuron and the lower motor neuron. The upper motor neurons originate from the cortex of the brain and project their axons down to the spinal cord to terminate in the ventral horns of the spinal cord. The ventral horn in the spinal cord is a column of grey matter located towards the front (or the ventral side) in the spinal cord. In the ventral horn of the spinal cord, the axons of the upper motor neurons synapse with lower motor neurons, whose cell bodies are located in the ventral horn. The lower motor neurons then have axons that exit the spinal cord and leave through nerve roots, to the peripheral nerves of your body, and eventually to the muscles that control your movement. Some of the lower motor neurons that control facial movement are located in the brainstem and not the spinal cord.Motor neurons can also be classified functionally by what they do, i.e. general somatic efferent neurons, general visceral efferent motor neurons, or special visceral efferent motor neurons.This can get much more complicated when we take into account the amount of descending input from the brain, brainstem, and cerebellum; and the integration that occurs at the level of the lower motor neuron cell body. Most simplistically, the function of the motor neuron is to transmit the message from the brain to the muscle.Diseases of motor neurons, such as amyotrophic lateral sclerosis and spinal muscular atrophy, can be very serious and currently have no cure.
Do worms and jellyfish have neurons?
Yes jelly fish have neurons. The neuron is the brain of the jelly fish
