The neuron is a nerve cell composed of a soma, dendrites, and a myelinized axon. Neurons connect to other nerons through synapsis.
b-1), c-3), d-4), e-2), f-5),
Neurons are nerve cells that transmit nerve impulses.
These cells are formed in general by a cellular body, dendrites, and an axon.
There is a directly proportional relationship between the axon diameter and the conduction velocity. Mielinized fibers are thick and their conduction velocities are very fast.
The conduction velocity increases substantially in myelinated fibers because of the high concentrations of sodium channels in the Ranvier nodes, which are not myelinated areas and the diameter of the axon becomes thinner.
Every neuron forms connections with other neurons known as synapsis. As it happens in every synapsis between neurons when a presynaptic neuron sends information, a neurotransmitter is released.
Neurotrasmitters are chemical substances that travel through the synaptic cleft to the junctional area of the other neuron and bind to its receptors in the postsynaptic membrane.
The binding neurotransmitter-receptor produces a depolarization of the cell called an excitatory postsynaptic potential.
An action potential is initiated and spreads to the rest of the membrane depolarizing it.
B. Dendrites ⇒ 1) Receives information from another neuron's axon terminal through the Synapse. Sends messages to the soma.
C. Myelin Sheath ⇒ 3) Insulating substance that protects the axon and speeds up the transmission of the messages.
D. Nodes of Ranvier ⇒ 4) Gaps in the myelin sheath.
E. Soma ⇒ 2) Contains the nucleus.
F. Synapse ⇒ 5) Gap between two neurons.
A. Connective nerve tissue,
G. Transmits movement to muscle.
