Iris diaphragm

Which part of the microscope increases or decreases the light intensity?


What is the platform that supports a microscope slide called?


What concentrates light onto the specimen (microscope)

Adjustment knob

What causes stage (or objective lens) to move upward or downward?

Objective lens system

After light passes through specimen it next enters this lens system.

stage (slide) Clip

Holds a microscope slide in position.


Contains a lens at the top of the body tube


Serves as a handle for carrying the microscope


Part to which the objective lenses are attached.

Field of view.

Circular area seen through the eyepiece.


What total magnification will be achieved if the 10x eyepiece and the 10x objective are used?


What total magnification will be achieved if the 10x eyepiece and 100x objective are used?


What total magnification will be achieved if the 10x eyepiece and 40x objective are used?


Loosely coiled fiber containing DNA and protein with nucleus.


Location of ATP production from digested food molecules.


Small RNA-containing particle for synthesis of protiens.

Vesicle (vacuole)

Membranous sac formed by a portion of the cell membrane pinching off.


Dense body of RNA within nucleus


Slender tubes that provide movement in cilia and flagella.

Endoplasmic reticulum

Composed of membrane-bound canals, sacs, and vesicles for tubular transport.


Occupies space between cell membrane and nucleus

Golgi Apparatus

Flattened membranous sacs that package a secretion.


Membranous sac that contains digestive enzymes.

Nuclear envelope

Separates nuclear contents from cytoplasm


Spherical organelle that contains chromatin and nucleolus.


Mitosis: Cell has passed the restriction checkpoint and completed DNA replication as well as replication of centroles and mitochondria and synthesis of extra membrane.


Mitosis: Chromosomes condenzse and become visible. Nuclear envelope and nucleolus disperse. Spindle apparatus forms.


Chromosomes align along equator or metaphase plate of cell.


Sister chromatids seperated to opposite poles of cell. Events begin which lead to cytokinesis.


Chromosomes complete migration toward centrioles. Chromosomes unwind from rods into threadlike chromatin when they approach one another.


Division of cytoplasm


Division of nucleus (simple cell division)


Telophase and cytokinesis


Has 23 chromosomes


Has 46 chromosomes

Adipose tissue

Areolar tissue

Blood tissue

Bone tissue

Cardiac muscle tissue

Dense Connective tissue

Elastic cartalige tissue

fibrocartilage tissue

Hyaline cartilage tissue

Nervous Tissue

Pseudostratified columnar epitheluim

Simple Columnar epitheluim

Simple cubidol epitheluim

Simple squamos epitheluim

Skeletal muscle tissue

Smooth Muscle tissue

Stratified squamouse epithelium

transitional epithelium

Hold structures together with tensile strength. Structures are skin muscles ends of bones and bones.

What are the functions and structures of connective tissue?

Binds, supports, protects, fills spaces, stores fat, and produces blood cells.

Describe the function of the connective tissue matrix.

Anchor down the epitheluim

What is the function of the basement membrane?

Epithelial- body surface, line organs and glands. Connective- throughout body
Muscle- Bone walls, hollow organs.
Nervous- Brain spinal cord

List the four major tissue types and their location.

Forms outer ear and parts of larnyx

Where is elastic cartalidge found in the body?

There is no direct blood flow to them.

Why is a sprained tendon or ligament slow to heal?

Neurons are nerve cells, neuroglia divide and are crucial to functioning of neurons.

Distinguish between neurons and neuroglia.

walls of hollow internal organs (uterus, bladder, stomach.)

Where is smooth muscle found in the body?

Skeletal muscle tissues- voluntary movement of skeletal parts. (striated) found attached to bones.
Smooth muscle- involuntary movement of internal organs. (non striated) walls of hollow organs.
Cardiac muscle- heart movements found in heart muscle.

Compare and contrast smooth, skeletal, and cardiac muscle tissues.
