The most common type of neuron found in the central nervous system is the multipolar neuron. These neurons have many dendrites and a single axon extending from the cell body. Multipolar neurons are involved in processing and transmitting information in the brain and spinal cord.
A single reflex arc during a muscle stretch reflex involves two synapses: one at the sensory neuron in the spinal cord where the signal is transmitted to the motor neuron, and another at the neuromuscular junction where the motor neuron stimulates the muscle to contract.
There is one epiglottis in the human body.
over 640 muscles are in the human body
Nervous System - since brain and the spinal cord are part of it.
The reflex arc includes the sensory neuron (sensory intake) to the motor neuron (motor response). This two neuron arc is the fastest. Many times an interneuron at the level of the spinal cord is involved. It passes information to the brain more slowly. It is like an "incident report".
In a simple reflex arc, there are typically three neurons and two synapses. The sensory neuron carries the signal from the receptor to the central nervous system, where it synapses with the interneuron. The interneuron then synapses with the motor neuron, which carries the signal to the effector organ to produce a response.

Multipolar neurons This is the most common type of neuron, with one axon and many dendrites. Multipolar neurons are so-named because they have many (multi-) processes that extend from the cell body: lots of dendrites plus a single axon. Functionally, these neurons are either motor (conducting impulses that will cause activity such as the contraction of muscles) or association (conducting impulses and permitting 'communication' between neurons within the central nervous system).
The parts of a generic neuron are:- soma - cell body axon - upto 1 meter long dendrite - many
No, they (sensory neurons) are either pseudounipolar or bipolar.To memorize, remember the word "M" for Multi-unipolar, and "M" for "Motor" (fibres).
'Made of' is difficult to say, but the reflex arc includes within it Sensory Nerve Fibres, Receptor Cells and Sensory Neurones. The effect of these is to bypass the normal interface with the central nervous system, so that the body responds instantly to potentially dangerous stimuli.
A bipolar neuron typically has one axon and one dendrite. This structure allows it to transmit signals efficiently between two distinct regions, such as sensory receptors and the central nervous system. Bipolar neurons are commonly found in sensory pathways, including the retina of the eye and the olfactory system.

The average human brain contains around 100 billion neurons, with each neuron having multiple dendrites. While the exact number of dendrites per neuron can vary, an estimate is that each neuron may have thousands of dendritic branches.
Interneurons, which make sense--they're the intermediaries. Many interneurons can send simultaneous messages to the brain and motor neurons--this is called a reflex arc.This is the interneuron. It is in the spinal cord. They act as a "go between" the sensory neuron and the motor neuron. They also send information to the brain so that the brain is aware.Reflex arcs do NOT have these interneurons.
