Vocab A&P1 Flashcards
Anatomy
The study of the structure of the body parts and their relationship with one another.
Physiology
The study of the functions of living organisms.
Ion
Atom or molecule with a positive or negative electric charge
Homeostasis
Stable internal environment of the body
Replication
Creating an identical copy of a cell, so its genes can be passed to each of its offspring.
Translation
One of the two major steps in the transfer of genetic code information, where info carried by mRNA is decoded and used to assemble polypeptides.
Transcription
One of the two major steps in the transfer of genetic code information, from a DNA base sequence to the complementary base sequence of an mRNA molecule
Triplet
Formed when three microtubules stack on top of one another
Codon
The three-base sequence on a messenger RNA molecule that provides the genetic info used in protein synthesis, code for a given amino acid
Gene
One of the biological units of heredity located in the chromatin, and it transmits heredity information
Chemical Level
The lowest level containing atoms, the tiny building blocks of matter which combine to form molecules such as water and proteins which help to form organelles, the basic components of microscopic cells.
Cellular Level
The 2nd level containing cells which are the smallest units of living things. Cells have some common functions but individual cells vary widely in size and shape, reflecting their unique function of the body
Tissue Level
The 3rd level containing tissues, which are groups of similar cells that have a common function, the four basic types are epithelium, muscle, connective and nervous
Organ Level
The 4th level where extremely complex functions become possible. example would be the process of the stomach digesting food
Organ System Level
The highest of all the levels which represents the sum total of all structural levels working together to keep us alive
