atrioventricular junction in the conduction system of the heart, the junction between the atrioventricular node and the nonbranching portion of the bundle of His.
cementoenamel junction the line at which the cementum covering the root of a tooth meets the enamel covering the crown.
gap junction a narrowed portion of the intercellular space, containing channels linking adjacent cells and through which can pass ions, most sugars, amino acids, nucleotides, vitamins, hormones, and cyclic AMP. In electrically excitable tissues the gap junctions serve to transmit electrical impulses via ionic currents and are known as electrotonic synapses; they are present in such tissues as myocardial tissue.
myoneural junction (neuromuscular junction) the site of junction of a motor nerve fiber and a skeletal muscle fiber that it innervates. The discoid expansion of the terminal branch of the axon forms the motor end plate, the neurotransmitter that diffuses across the synapse is acetylcholine.
sclerocorneal junction limbus (def. 2).
ureteropelvic junction the area where the renal pelvis meets the ureter.

u·re·ter·o·pel·vic junc·tion (UPJ),

site of origin of the ureter from the renal pelvis, a common location for congenital or acquired obstruction.

ureteropelvic junction

the area where the renal pelvis meets the ureter.
