GENERAL HISTOLOGY

Detailed explanation-1: -endoplasmic reticulum: A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.

Detailed explanation-2: -From the endoplasmic reticulum, proteins are transported in vesicles to the Golgi apparatus, where they are further processed and sorted for transport to lysosomes, the plasma membrane, or secretion from the cell.

Detailed explanation-3: -The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.

Detailed explanation-4: -Golgi Apparatus. The Golgi apparatus (Figure 5.6. 5) is a large organelle that processes proteins and prepares them for use both inside and outside the cell.
