HBS UNIT 1 Flashcards
Structural Hierarchy of The Body
Chemical - Cells - Tissues - Organ - Organ System - Organism
Difference Between Cells and Tissue
Tissue is an integrated group of cells working together
Epithelial
Tightly packed sheets, it’s function is absorption, protection, transportation and sensing (Skin)
Connective
connects/supports (Bone, Cartilage , Adipose ,Blood,ligaments, and tendons)
Muscle
Movement (Tendons)
Nervous
Reactions (Neurons)
Functions of Skeletal System
Help gives the body shape, provides muscle attachment sites to help move the body, provides protection, also it produces blood cells and stores minerals
Skeletal System Divisions
Axial: Vertebral column, Skull, Ribs, and Sternum
Appendicular: Pectoral Girdle, Pelvic Girdle, and Appendages upper and lower
Bones of the Pelvis
Composed of two coxal hip bones (ilium, ischium, pubic symphysis)
Bones of the Skull
Frontal, Temporal, Parietal, and occipital
Types of Ribs and how they’re Attached
True Ribs - First 7 connect to the sternum
False Ribs - 8-12 do not attach directly to the sternum (cartilage)
Floating Ribs - 11 and 12 they do not attach to sternum or vertabrae
Sutures of the Skull
Coronal - Frontal to pariental
Lambdoid - Occipital to Parietal
Saggital - Between Parietal Bone
Squamosal - Temporal to Parietal bone
Function and Location of the obicularis oris, obicularis oculi and temporalis
obicularis oris - located around your lips and helps you kiss
obicularis oculi - located around your eye and helps you blink
temporal - above and in front of your eye helps you chew
What does the field of Forensic Anthropology study?
Forensic Anthropologists use data criteria and techniques to determine the sex, age, genetic population, or parentage of skeletal or biological materials in questions of civil or criminal law
What bones are used to determine height?
Femur, Tibia and Humerus
Conversion of CM to Feet
2.54 CM = 1 inch
Bone used to determine gender? how do males and females differ?
Pelvis is used to determine gender (females more round and males are V or Heart shaped)
Where do restriction enzymes come from?
Restriction enzymes are found naturally in bacteria
Why do they have restriction enzymes?
They can be used to cut foreign DNA fragments in specific places
How do restriction enzymes get their name?
Restriction enzymes are named for the bacteria from which they’re isolated
What location do restriction enzymes cut?
They cut a specific combination or sequence of nucleotides
What is a palindrome?
word or sequence that reads the same in either direction
What is RFLP? (restriction fragment length polymorphism)
A collection of DNA fragments of precisely defined length
What is PCR (polymorph chain reaction) and why do we use it?
Polymorph Chain Reaction amplifies DNA found at crime scenes into billions of copies to which makes identifying the culprit easier
