In contrast, in the single example from a Mopan story, time flow and plot development are represented along the sagittal (i.e. front-back) axis. There is no Mopan example in which the projected lateral axis is used to represent time-flow or plot development.

A) Transections of the heart following the classical human body planes (1) frontal plane, (2) horizontal plane and (3) sagittal plane. (B) Transections of the heart following the heart planes that cut the body obliquely. These are the planes used by the cardiac imaging experts (1) short-axis (transverse) view, in this case at mid-level (see B(1)) ...

Fig. 4. Slices through a three-dimensional image of a fixed mouse embryo (14 days post conception). Data were acquired with a UFLARE sequence with eight echoes TR/TE = 2000 ms/38 ms resolution 50 pm in the long axis, 80 pm in the other two dimensions. Sagittal (top) and coronal (bottom) slices show a wealth of anatomic detail. Scale bar = 1 nun (image courtesy B. Boulat and R. Jacobs).

Purkinje cells. The recurrent collaterals extend into the molecular layer where they contact basket cells (O Donoghue et al., 1989). The whole collateral arborization is oriented perpendicular to the long axis of the folia, i.e. in the same plane as the dendritic tree of the Purkinje cell. In the cat it measures 300-700 //m in the sagittal and 100 00 m in the transverse direction (Bishop, 1988). The width of the arborization and its penetration in the molecular and granular layers varies for different parts of the cerebellum. Recurrent collaterals of Purkinje cell axons are constituents of the infra- and supraganglionic plexus. The main Purkinje cell axon enters and traverses the white matter to terminate on cells of the cerebellar or the vestibular nuclei.

The tibiofemoral joint is mainly a joint with two degrees of freedom. The first degree of freedom allows movements of flexion and extension in the sagittal plane. The axis of rotation lies perpendicular to the... 

The sagittal plane is the y, z plane and the frontal (or coronal) plane is the y, x plane and the horizontal (or transverse) plane is the x, z plane. Movements are described in relation to the origin of the coordinate system. The arrows indicate the positive direction of each axis. An anterior translation is +z a posterior translation is —z. Clockwise rotations are +9, and counterclockwise rotations are —9. 

The optical properties of, e.g., lenses change from the center to the comer. To describe this behavior a different graph is used. Instead of spatial frequency the x-axis represents the distance from the image center. The graph contains at least two pairs of lines, each pair at a certain spatial frequency. A pair consists of a line for sagittal and tangential orientation. An example of an optical lens system is given in Fig. 4.
