Quiz for Lab Exam 1/29/12
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)
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.
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.
Composed of membrane-bound canals, sacs, and vesicles for tubular transport.
Occupies space between cell membrane and nucleus
Flattened membranous sacs that package a secretion.
Membranous sac that contains digestive enzymes.
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
Cardiac muscle tissue
Dense Connective tissue
Elastic cartalige tissue
Hyaline cartilage tissue
Pseudostratified columnar epitheluim
Simple Columnar epitheluim
Simple cubidol epitheluim
Simple squamos epitheluim
Skeletal muscle tissue
Smooth Muscle tissue
Stratified squamouse 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.
Substage illuminator (lamp)
What is G?
Coarse adjustment knob
What is I?
Fine adjustment knob
What is J?
Stage control knob
What is K?
