Human Anatomy Cell Anatomy By/ Dr. Diana Eid  What is Anatomy? Anatomy is the study of the structure of the body. Gross Microscopic Anatomy Anatomy Reginal, Study of the cells systematic, and tissues under developmental microscopes & imaging (histology) anatomy  Gross Anatomy: Regional anatomy : the study of a certain region or part of the human body e.g. limbs – head & neck. Systemic anatomy: the study of a certain system of the human body e.g. nervous system – cardiovascular system. Developmental anatomy: the study of the development of the embryo (embryology). Imaging anatomy: X-ray – CT - MRI Cell Anatomy  What is the cell? Cells are the basic building blocks of all living things. They provide structure for the body.  Cell Anatomy: Simply cells are membranous sacs containing fluid and floating particles. There are many different types, sizes. & shapes of cells in the body. Any cell consists of three main parts: cell membrane nucleus (except mature red blood cells) cytoplasm Cell (plasma) membrane: Every cell in the body is enclosed by cell membrane. It separates extracellular fluid from intracellular fluid. It maintains integrity of a cell & control passage of materials into and out of the cell. It provide structural support of the cell Nucleus: It is the control center of the cell. Consists of nuclear membrane and fluid (nucleoplasm). The largest intracellular structure, spherical or ellipsoid in shape. The nucleus contains the DNA, the genetic material of the cell. The nucleus determines how the cell will function & the basic structure of the cell. Cytoplasm: The cytoplasm is a gel-like fluid inside the cell. All functions of the cell are carried out in the cytoplasm of a cell. Provides a medium for chemical reaction within the cell. All cell organelles are bathed in the cytoplasm.  Cytoplasmic organelles: Are little organelles suspended in the cytoplasm. Each organelle has a specific structure & function. Examples: - mitochondrion (produce energy of the cell, powerhouse of the cell) - ribosomes (form protiens) - golgi apparatus (post office of the cell, transport materials within cells). - lysosomes (protect cells, cell’s suicide bags). https://youtu.be/n_Jz9f7V6uA Body Tissues: Tissues: Is a group of cells that have similar structure and function. Intercellular Matrix: fluid fill the space in between cells of the same tissue, it contain special substances such as salts & fibers that unique to specific tissue There are 4 main types of tissues each is designed for specific functions: 1- epithelial 2- connective 3- muscular 4- nervous  The cell is the building unit of the body Cell + cell tissues organs systems body  (167) Biology: Cell Structure I Nucleus Medical Media - YouTube
