Skeleton Labeling Contest!

I had a lot of fun with this contest, and studied one part of the skull- anterior view! This was a little bit of a challenge, more than I expected it to be. But I did it :) I was extremely nervous when trying to label this skull (my sticky notes were not sticking!) But oh well...

Bone Structure Quiz... uhhhh

Since I don't do good on test/quiz/etc... and after taking the bone structure quiz, it didn't show much that I learned anything.  I am starting to get the idea of what kind of different fractures do what and what they mean.  So I put some pictures up with the meaning underneath them to show what I know.  Some fractures are caused by sports injury, old age, common.. just because.  Bones can fracture doing anything not just a hard fall, or playing rough or anything like that.. it can just happen.  So BE CAREFUL!!!

Broken Bones

Spiral Fracture- most common in sports injury

Compound Fracture- A fracture in which the bone is crushed; common in the vertebral column

Greenstick Fracture- A break common in children; bone splinters, but break is incomplete

Comminuted Fracture- Often seen in the brittle bones of the elderly

Simple Fracture- Also called a closed fracture

Depressed Fracture- A common type of skull fracture

Open Reduction- Surgical realignment of broken bone ends

Closed Reduction- Nonsurgical realignment of broken bone ends and splinting of bone

Nondisplaced Fracture- Bone ends retaining their normal position

Linear Fracture- Epiphysis separates from diaphysis along epiphyseal line;

occurs where cartilage cells are dying

Compression Fracture- A fracture in which the bone is crushed; common in the vertebral column

  I read an article about engineering skin, and I thought that it was kind of interesting and it has been approved by the U.S Food and Drug Association (FDA).
   In the lab, they grow cartilage and skin and it goes to the need of severely burned victims.  They are working their way up making bones so it can help people that have artheritus and blood vessel, muscle tissue and cardiac valves could save a ton of people with cardiovascular diseases.  FDA believes that custom made hearts, bone marrow, and bladders are the best ideas for most life threatening illnessess.  At the Tissue Engineering and Organ Fabrications Laboratory at Massachusetts General Hopsital, doctors say they are working on 30 different tissues today.
  So, I guess that you have been severely burned or are seriously injured that you have no skin left in that area, a non- used skin would be better than not having anything to protect your body from that type of injury or whatever.  Cardiovascular diseases happen when the function of you heart or blood vessels are abnormal.  It can make a person more suspect able to heart attacks, heart failure, stroke, and even worse, sudden death.  I would much rather have a lab-grown function of some type to help me from fearing that I could die.

Human Epithelia

Simple Squamous Epithelium



Characteristics of simple squamous epithelial tissue: one layer of flat cells with disk shaped nuclei.
Function: Filtration and diffusion




Examples of simple squamous epithelial tissue: lining in lymphatic vessels.









Simple Cuboidal Epithelium


Characteristics of simple cuboidal epithelial tissue: one layer of cube-like cells with spherical central nuclei
Function: secretion and absorption



Examples of simple cuboidal epithelial tissue: Kidney tubules, duct and secretory portions of small glands, ovary surfaces






Simple Columnar Epithelium


Characteristics of simple columnar epithelial tissue: One layer of column shaped cells with oval nuclei. Most have cilia (hair-like things that helps them move)
Function: absorption and secretion


Examples of simple columnar epithelial tissue: nonciliated type line digestive tract and gallbladder. ciliated type line small bronchi, uterine types and some regions of the urterus. cilia help move substances through the internal passageways

Pseudo-stratified Columnar Epithelium



Characteristics of pseudostratified columnar epithelial tissue: column shaped cells with different heights
Function: secretion and propulsion of mucus


Examples of pseudostratified columnar epithelial tissue: present in male-sperm carrying ducts, and trachea











Stratified Squamous Epithelium


Characteristics of stratified squamous epithelial tissues: thick membrane that consists of many layers of flat cells
Function: protection to underlying areas subject to abrasion.



Examples of stratified squamous epithelial tissues: forms the outside layer of skin, lining of the esophagus mouth and vagina.





Stratified Cuboidal Epithelium

Characteristics of stratified cuboidal epithelial tissues: Cube shaped cells in multiple layers


Examples of stratified cuboidal epithelial tissues: protects the ducts of some sweat glands and mammary glands and salivary glands















Stratified Columnar Epithelium



Characteristics of stratified columnar epithelial tissue: column shaped cells stacked on top of each other in multiple layers.


Examples of stratified columnar epithelial tissue: pharynx, male urethra, and glandular ducts









Transitional Epithelium



Characteristics of transitional epithelial tissues: several layers of cells, base cells are cuboidal and the surface cells are dome shaped
Functions: to stretch and retract for the bladder.



Examples of transitional epithelial tissues: lines the bladder the ureters and part of the urethra
