Object Name # of Images Description
Z bands 1 Border between two sarcomeres. The area at which the thin filaments of adjacent sarcomeres attach. Named from the German Zwischenscheibe meaning the band in between.
Z line 1 Border between two sarcomeres. The area at which the thin filaments of adjacent sarcomeres attach. Named from the German Zwischenscheibe meaning the band in between.
Z lines 1 Border between two sarcomeres. The area at which the thin filaments of adjacent sarcomeres attach. Named from the German Zwischenscheibe meaning the band in between.
Z lines 2 Border between two sarcomeres. The area at which the thin filaments of adjacent sarcomeres attach. Named from the German Zwischenscheibe meaning the band in between.

Zona fasciculata 2 The middle of the three layers of the adrenal cortex. Produces mostly glucocorticoids. Stimulated by ACTH.

Zona glomerulosa 2 The outermost of the three layers of the adrenal cortex. Produces mineralocorticoids. Part of the renin-angiotensin circuit.

Zona pellucida 1 Amorphous extracellular layer surrounding primary and secondary oocytes in ovarian follicles. Produced by the oocyte and surrounding follicular cells.
Zona pellucida 3 Amorphous extracellular layer surrounding primary and secondary oocytes in ovarian follicles. Produced by the oocyte and surrounding follicular cells.
Zona reticularis 1 The innermost of the three layers of the adrenal cortex. Probably produces sex steroids.
Zona reticularis 1 The innermost of the three layers of the adrenal cortex. Probably produces sex steroids.
Zona reticularis 2 The innermost of the three layers of the adrenal cortex. Probably produces sex steroids.
Zonae pellucidae 1 Amorphous extracellular layers surrounding primary and secondary oocytes in ovarian follicles. Produced by the oocytes and surrounding follicular cells.
Zonula occludens 1 Forms an impermeable seal between two cells. In the GI tract tight junctions prevent the escape of digestive enzymes from the lumen into the intracellular space. Also prevent lateral migration of proteins of the apical cell membrane.

Zymogen granules 1 Storage vesicles containing inactive (ordinarily) precursors of proteolytic enzymes. Become converted into active digestive enzymes in the gut. Sometimes visible as granules in LM, as is the case here.
