medullary reticular nucleus
Acronym:
The term medullary reticular nucleus refers to the portion of the medullary reticular formation located caudal to the gigantocellular nucleus and the inferior olive of the human ( Paxinos-2012 ), the macaque ( Paxinos-2009a ), the rat ( Swanson-2004 ) and the mouse ( Hof-2000 ). Different authors subdivide it differently. But, all regard it as including two parts, the dorsal part of the medullary reticular nucleus and the ventral part of the medullary reticular nucleus ( Swanson-2000 ).
     Many consider the transition zone between the dorsal and ventral parts to be a separate structure, a caudal extension of the intermediate reticular nucleus, which separates the gigantocellular nucleus and the parvicellular reticular nucleus more rostrally ( Paxinos-2012; Paxinos-2009b; Paxinos-2009a; Hof-2000 ). Some further subdivide the ventral part of the medullary reticular nucleus of the macaque to include a medial medullary reticular nucleus ( Paxinos-2009a ).
     Functionally the medullary reticular nucleus belongs to the reticular formation (functional) of the subcortical motor system ( Swanson-2004 ).
