Contents
What is located at the axon end?Axon terminals are the distal ends in the branches of an axon. An axon nerve fiber is an elongated projection of a nerve cell (neuron). This fiber transmits electrical impulses called action potentials from the body of the nerve cell (soma) to other nerve cells.
Which organelles are found in the cell body of the neuron?Many organelles are found in the cell body, including the large endoplasmic reticulum and granules made up of free polysomes, called Nissl granules. The cell nucleus plays a key role in the body. The nucleus is the source of most of the RNA produced by nerve cells. are specialized ports. If the synapse is between neurons, the pre-synaptic end is called "presynaptic neuron" and the post-synaptic neuron is called "postsynaptic neuron".
What is the protrusion of the axon membrane?
In the central and peripheral nervous systems, The insulating material in the form of a layer surrounding the axon of the nerve cell is called myelin. Myelin is a projection of neuroglia.
What is found in the structure of a neuron?Structure of the Neuron The main parts of the neuron are the nucleus, the cell body and the dendrites. There are many connections between neurons through axons or small branches. Axons help build networks whose function is to transmit messages from one neuron to another.
Where are neurotransmitters found?Neurotransmitters are one of the chemicals found in the brain and are hormones produced by the body. It allows the message that came to the gap in the synapse region to bypass and pass to the opposite side more easily.
What is not found in a mature neuron?
It contains organelles. •There are no centrioles in mature nerve cells.
What does postsynaptic potential mean?
Potential changes that occur as a result of conductivity or permeability changes in postsynaptic membranes against one or more ions as a result of synaptic transmissions are called postsynaptic potential.< /p> How does synaptic transmission happen?
If the cells are far from each other, information transfer takes place through chemical factors. Information transfer between neighboring nerve cells or between a neighboring nerve cell and a muscle cell is called synaptic transmission, and the specialized areas where this communication takes place between neighboring cells are called synapses.
