- The nervous system, the major anatomical and functional subdivisions. Three functional properties found in all neurons; define the three most basic functional categories of neurons List the six types of cells that aid neuronsReceptor for epinephrine consists of seven transmembrane helices. T/FNeuromuscular junction, also called myoneural junction, site of chemical communication between a nerve fibre and a muscle cell. The neuromuscular junction is analogous to the synapse between two neurons. A nerve fibre divides into many terminal branches; each terminal ends on a region of muscle fibre called the end plate. Synaptic Cleft is the space between the presynaptic terminal and postsynaptic cell. It is roughly the size of 30 nm. The synaptic cleft allows the neurotransmitters to diffuse and reach the other side of the synapse or the neuromuscular junction. It also contains enzymes for the degradation of the excess or extra neurotransmitters. Embedded in the end plate are thousands of receptors, which are long protein molecules that form channels through the membrane. Upon stimulation by a nerve impulse, the terminal releases the chemical neurotransmitter acetylcholine from synaptic vesicles. Acetylcholine then binds to the receptors, the channels open, and sodium ions flow into…
