The upper part (Z’) cecupies the groove between the neural spines 
and the zygapophyses. It is bound down by a dense tendinous fascia, 
and shows tendinous thickenings passing downward and slightly for- 
ward, from the summits of the spines to the articular processes. 
The lower part (ZL?) occupies the groove between the zygapo- . 
physes and the transverse processes, and consists of a number of 
cones, with the muscular apices posterior and the tendinous apo- 
neuroses anterior. Thus the muscle on being cut exhibits a number 
of aponeurotic layers placed one within the other, and shows exter- 
nally tendinous thickenings, passing backward and very slightly 
downward, from the zygapophyses to the ends of the transverse 
processes. 
Complexus major. This is merely the most anterior portion of 
the upper part of the longissimus dorsi. Passing to the back of the 
skull, internal to the postero-superior part of the temporal, it is 
deeply inserted into the side of the cranium, beneath the projecting 
occipital crest. 
The complerus minor (figs. 1, 6, and 7, C’) is the most anterior 

Deepest muscles of ventral aspect of neck.
