A somatic cell is a general term for a body cell and all human cells except for the cells that produce eggs and sperm which are referred to as germ cells are somatic cells. Parts of a human cell. The major parts of a cell are the nucleus cytoplasm and cell membrane.

Smooth er and rough er. The nucleus contains a nucleolus and is separated from the cytoplasm by the nuclear envelope. Cytology is the branch of microscopic anatomy that studies the cells and histology is the branch of microscopic anatomy that studies tissues.

Functions include odification packaging and distribution of proteins and lipids for secretion or internal use. From the smallest to the largest part of the human anatomy in that sequential order are the. The endoplasmic reticulum er is a network of membranes that form channels throughout the cytoplasm from the nucleus to the plasma membrane.

The human body is made up of 50 to 100 trillion cells and each cell is designed to perform a variety of functions to keep your body is functioning shape. Anatomy and physiology chapter 3. Cell theory in the late 1600s an english scientist named robert hook was the first to observe plant cells with a crude microscope.
