Jan 15, 2021 · The endoplasmic reticulum (ER) is a large organelle made of membranous sheets and tubules that begin near the nucleus and extend across the cell. The endoplasmic reticulum creates, packages, and secretes many of the products created by a cell. Ribosomes, which create proteins, line a portion of the endoplasmic reticulum.

Aug 14, 2020 · Human Anatomy (ana- = “up”, tome = “to cut”) is often defined as the study of structures in the human body. Anatomy focuses on the description of form, or how body structures at different levels look. Gross anatomy studies macroscopic structures (for example, the body, organs, and organ systems), and histology studies microscopic ...

Anatomical terms of movement are used to describe ways in which the body moves due to the action of certain muscles. This movement will occur at a joint which is an articulation between at least 2 bones. The main movements in the sagittal plane are flexion and extension. In the coronal plane we have abduction and adduction.
