How does gross anatomy differ from microscopic anatomy and developmental anatomy?
Gross anatomy is the study of the anatomical structures and microscopic is the study of tiny anatomical structures such as tissues and cells.
What is the difference between cytology and histology
Histology is the study of the tissue and cytology is the study of cells
What is the Principle of Complementarity of structure and function?
Function depends on the structure
What are the six levels of organization of an organism?
Chemical/molecular, cells, tissues, organs, organ systems, organisms
Maintaining Homeostasis
Tendency to resist change in order to maintain a stable, relatively constant internal environment.
Difference between catabolism and anabolism
Anabolism creates molecules the body needs and catabolism breaks down complex molecules and releases energy for the body to use.
What are the variables of homeostasis
Internal, physical, and chemical
What two systems play a major role in maintaining homeostasis?
Nervous and endocrine
What are the three main components involved in homeostasis and what are they responsible for?
A receptor that senses environmental stimuli, integrating center that receives information from receptor, and effector.
What is the difference between positive and negative feedback
What are the two main sets of cavities in the body?
Ventral and dorsal cavities
What is a serous membrane?
A tissue that lines certain internal cavities of the body forming a smooth two layered membrane that is lubricated.
What are the 2 layers of a serous membrane
The parietal layer lines the wall of the body cavity and the visceral layer covers the organs.
What is the difference between dehydration synthesis and hydrolysis?
Dehydration synthesis is when a water molecule is formed because of a covalent bond and hydrolysis is when a water molecule is consumed because of a breaking of a covalent bond.
What is the difference between a saturated and an unsaturated fatty acid?
Saturated fatty acids lack double bonds between carbon atoms and unsaturated fatty acids have at least one double bond in the fatty acid chain.
What is a Phospholipid
a lipid containing a phosphate group in its molecule
What is the function of DNA?
What are the three main parts of a cell
Cell membrane, the nucleus, and cytoplasm
What is extracellular matrix
Its a non-cellular component present in all tissues and organs and two components are polysaccharide chains and fibrous proteins.
What is the plasma membrane and what is its function?
What is intracellular fluid compared (ICF) to extracellular fluid (ECF)
Intracellular fluid contains K+ and is the liquid found inside of cells. Extracellular fluid contains Na+ and found outside the cell.
What is the function of membrane proteins?
Found within plasma membrane and channels or transports molecules across the membrane. Also acts as cell receptors.
What is the glycocalyx
Also known as the pericellular matrix and is a glycoprotein and glycolipid covering that surrounds the cell membranes of bacteria, epithelia, and other cells.
Glycocalyx plays a major role in regulation of endothelial vascular tissue
What is an intercalated disc made up of?
Fascia adherens, desmosomes, and gap junctions
