This theory of aging proposes that aging is programmed into our genes. The best evidence for this theory involvees telomeres, strutures that limit the maximum number of times cells can divide.
Genetic theory of aging

Which type of cell?
This cell carries the respiratory gases, oxygen and carbon dioxide. Its concave disc shape provides extra surface area for the uptake of respiratory gases. This steamlined shape also allows the cell to flow easily through the bloodstream. So much oxygen-carrying pigment is packed in erythrocytes that all other organelles have been shed to make room.
Erythrocyte (red blood cell)

Which type of cell?
The shape of these cells allows the maximum number of epithelial cells to be packed together in a sheet. This cell has abundant intermediate filaments that resist tearing when it is rubbed or pulled. Some of these cells are gland cells, with an abundant rough ER, Golgi apparatus, and secretory granules
Epithelial cells
Which parts does the back (dorsal) region include? (6)
Scapular, Vertebral, Lumbar, Sacral, Gluteal, Perineal (between anus and external genitalia)
The abdominopelvic cavity is divided into which two parts
(a) the superior part called the abdominal cavity (liver, stomach, kidneys, and other organs) (b) the inferior part, or pelvic cavity (bladder, some reproductive organs, and the rectum).
Which type of cell?
The elongated shape of this cell extends along the cablelike fibers that it secretes. It also has an abundant rough ER and a large Golgi apparatus to make and secrete the protein components of these fibers.
Fibroblast
Structure: Rodlike, double-membrane structures; inner membrane folded into projections called cristae
Mitochondira: Site of ATP synthesis; powerhouse of the cell
This theory of cellular aging proposes that free radicals are primarlily the by-products of normal cellular metabolism, although they also form in rsponse to external insults, such as radiation and chemical pollutants. **Free radicals build up and progressively damage the essential cell molecules. **
Free radical theory
Orientation and Directional term: Closer to the origin of the body part or the point of attachment of a limg to the body trunk
Proximal
Structure: Fine filaments of the contractile protein actin
Microfilaments: involved in muscle contraction and other types of intracellular movement; help form the cell’s cytoskeleton
Anatomical position and regional term: Cephalic, what does it stand for and what 5 features does it include?
Head; Frontal (forehead), orbital (eyes), Nasal (nose), Oral (mouth), Mental (chin)
(8)

Hypogastric (pubic) region
Serosae associated with the abdominal viscera

The thoracic cavity has three parts:
(a) two lateral parts, each containing a lung surrounded by a pleural cavity and (b) a central band of organs called the **mediastinum. **
The Ventral Body Cavity has two main divisions:
(1) a superior thoracic cavity surounded by the ribs and the muslces of the chest wall and (2) an inferior abdominopelvic cavity surrounded by the abdominal walls and pelvic girdle
