Explanation:

The _axon_ conducts impulses toward the synaptic terminals.  

The _synaptic end bulb _ is the enlarged end of an axon.  

The _neurons _contains neurotransmitters.  

The _Nissl bodies _ is a cluster of RER and free ribosomes.  

The_cell body of a neuron _ is another term for the soma of a neuron.  

The _axolemma _ is the membrane of the axon.  

The _BB-endothelial cells _ is a cell that forms the blood 13brain barrier.  

The _telodendria_is a fine branch of an axon.

Explanation:

Axon (or nerve fibre): is a long projection of a nerve cell or neuron in vertebrates animals, that typically conducts electrical impulses away from the nerve cell body.

Synaptic end bulb: They contains synaptic vesicles that are filled with a neurotransmitter substance. The neurotransmitter substance is responsible for the transmission of impulses from axon to muscle fibers through the synapse.

Neurons: They are nerve cells and nerve fibers, which are electrically excitable cells in the nervous system that transmit and process information. Neurons are the basic working unit of the brain.

Nissl bodies: They synthesize proteins for intracellular use, they are responsible for the manufacture and release of proteins and amino acids in the body system.

Cell body of a neuron:  The cell body is the part of the neuron that contains the nucleus and as well connects the dendrites, that bring information into the neuron and the axon which sends information to other neurons. They control all of the functions of the cell.

Axolemma: it is the cell membrane of an axon, it is responsible for maintaining the membrane of the axon and contains ion channels through which ions flows rapidly.

BB-endothelial cells : They are the main regulator of vascular homeostasis, they interacts with circulating cells on one hand and the cells present in the vascular wall on the other hand.

Telodendria: It is the branched ends of nerve cells, they establishes the functional contact with other nerve cells.
