Schweigger-Seidel,

Franz, German physiologist, 1834-1871.
sheath of Schweigger-Seidel - (1) a spherical or spindle-shaped condensation of phagocytic macrophages in a reticular stroma investing the wall of the splenic arterial capillaries; - (2) the outer end of the inner segment of the retinal rods and cones. Synonym(s): ellipsoid

ellipsoid

1. The refractile outer portion of the inner member of a rod or cone cell. It is located between the myoid and the outer member of the cell, and contains mitochondria. The myoid is in contact with the external limiting membrane of the retina while the outer member is next to the pigment epithelium. 2. Surface of revolution generated by rotating an ellipse about a major or minor axis.
