What is the definition of microscopic Anatomy
Examines cells and molecules
Definition of cytology
Study of cells
Definition of Histology
Study of tissues
What is the definition of physiology?
Is the study of functions of anatomical structures
What is the smallest living thing?
Cell
What is the smallest organism?
Atom
What are the levels of Hierarchy from smallest to biggest
Atom, Molecule, organelles, cells, tissues, organ, organ system
Atom level of Hierarchy
The most basic complete unit of an element
Molecule level of Hierarchy
A group of atoms bonded together, representing the smallest fundamental unit of a
chemical compound that can take part in a chemical reaction
Organelles Level of Hierarchy
Are cells parts that function within a cell
Cells Level of Hierarchy
The Basic structural unit of an organism from which living things created. Is one
individual cell
Tissues Level of Hierarchy
A group of cells with similar structure that functions together as a unit, but at a lower
level than organs
Organ Level of Hierarchy
A self contained part of an organism that performs specific functions. Is formed by two
or more similar tissues
Organ System Level Of Hierarchy
Functional groups of organs that work together within the body: Circulatory,
integumentary, skeletal, reproductive, digestive, urinary, respiratory, endocrine,
lymphatic, muscular and nervous
How many organ systems are there?
11
What are the organ systems?
,Circulatory, integumentary, skeletal, reproductive, digestive, urinary, respiratory,
endocrine, lymphatic, muscular and nervous
What is in the structure of a cell?
Nucleus, ribosomes, Golgi apparatus, vacuoles, cytoskeletal, microtubules, cytosol, cell
membrane, endoplasmic reticulum, mitochondria
Nucleus Function
Holds the cells DNA in form of chromatin
Ribosomes Function
Small structures that build proteins "amino acids"
Golgi apparatus Function
Modifies and packages proteins secreted from cell
Vacuoles Function
Storage, digestion, and waste removal
Cytoskeletal function
Series of rod shaped proteins that provide shape/support the cell
Microtubules Function
Part of the cytoskeletal
Cytosol definition
Liquid material in the cell
Cell membrane function
Separate internal and external cellular environment that allows material to enter and exit
cell
Endoplasmic reticulum function
Smooth or rough transport system of the cell
Mitochondria function
Generates ATP powerhouse of the cell. ATP production is called cellular respiration
What structures are in an animal cell
Centrosome, centriole, lysosomes, cilia, and flagella
Centrosome definition
Pairs of centrioles involved in mitosis
Centriole definition
Cylinders involved in cellular division
Lysosomes function
The purpose of the lysosome is to digest things. they might be used to digest food or
break down the cell when it dies
Cilia function
Cause cell to move
Flagella definition
Whip tail to move cell
Definition of Tissues
group of similar cells that perform a particular function
Group of cells
What are the four types of tissues?
muscle, nerve, epithelial, connective
Definition of epithelial tissue plus examples and function
, (Dense, loose, or fatty) Example: Tissue, cartilage, tendons, ligaments, fat, blood, lymph
It protects and binds body parts
Funciton of cartilage and example
Cushions and provides structural support
FIbrous
Function of blood
Transport oxygen to cells and removes waste. Also carries hormones and defends
against disease
Function of bone
(Hard). Produces red blood cells
Function of Muscle tissue
Supports and moves body
What are the three types of muscle tissue
smooth, cardiac, skeletal
Nervous tissue example
Brain, spinal cord, and nerves
Neurons Function
Control responses to changes in environment
Mitosis and its phases
It has 4 phases. Pink MAT / Prophase, Metaphase, Anaphase, Telophase
Interphase
Cell prepares for division by replicating genetic/cytoplasmic material
Prophase
Chromatin thickens into chromosomes and the nuclear membrane begins to
disintegrate. Pairs of centrioles move to opposite sides of cell and spindle fibers form
Metaphase
Spindle moves to the center of the cell and chromosome pairs align along the center of
the spindle structure.
Anaphase
Chromosome pairs pull apart into daughter chromosomes
Telophase
Spindle disintegrates, nuclear membrane reforms or is pinched
Cytokinesis
Physical splitting of the cell
Meiosis
Same as mitosis except happens twice, results in four daughter cells instead of two.
Mature haploid male and female germ cell uniting in sexual reproduction
Gametes in female
Egg
Gametes in male
Sperm
Meiosis is when
Gametes produce a zygote
Zygote
