Chpt. 1 pt. 1 Anatomy
Anatomy | study of the structure of an organism (what is it?) |
Physiology | A specialized discipline within the field of biology. The study of the function of the living organism, its parts, and the chemical processes involved. (How it works.) |
Sagittal | splits the body into left and right halves |
Frontal/Coronal | Splits the body into front and back halves |
Transverse | Splits the body into top and bottom halves |
Anterior | toward the front opposite: posterior |
Posterior | toward the back opposite: anterior |
Ventral | away from the backbone opposite: dorsal |
Dorsal | toward the backbone opposite: ventral |
Central | Pertaining to or situated at the center opposite: peripheral |
Peripheral | away from the center opposite: central |
Superficial | Toward the surface opposite: deep |
Deep | away from the surface opposite: superficial |
External | Toward the outer surface opposite: internal |
Internal | Toward the inner surface opposite: external |
Medial | Toward the axis or midline opposite: lateral |
Lateral | Away from the axis or midline opposite: medial |
Proximal | Toward the body opposite: distal |
Distal | Away from the midline opposite: proximal |
Superior | Upper, above opposite: inferior |
Inferior | Lower, below opposite: superior |
Irritable | able to be affected or stimulated by a change in environment |
Metabolism | use food and oxygen to build and repair and to create heat and energy |
How we are put together | cells-tissues-organs-systems |
How many cells are in our bodies | 100 trillion (some are there for life like the nervous system while others die and are relaced like skin and others live only about 4 months like blood.) |
Cytology | the study of cells |
protoplasm | fluid that makes up a cell |
Nucleus | Chromatin- Contains DNA Nucleolus- Contains Ribosomes |
Why is protein important | helps keep the cells healthy |
cytoplasm (fluid) | 10-85% H2O 20% protein substance |
Centrosome | for cell division structure in cytoplasm |
Mitochondrian | provides energy or ATP structure in cytoplasm |
Golgi Apparatus | Stores secretary substances structure in cytoplasm |
Lipids | Energy storage structure in cytoplasm |
Vacuoles | Membrane-bound sacs within the cytoplasm of a cell structure in cytoplasm |
Glycogen Particles | primary energy source during activity structure in cytoplasm |
Crystalline Inclusion Bodies | structure in cytoplasm |
Lysosomes | Digestive organs of the cell structure in cytoplasm |
Inert Substances | structure in cytoplasm |
Parts of the cell | cilia, Lysosome, centrioles, microtubules, golgi apparatus, smooth endoplasmic reticulum (ER), Mitochondrion, Rough ER, Cell membrane, cytoplasm, nucleolus, chromatin, ribosomes, nuclear membrane |
