Tissue Lab:

B. This slide shows an epithelium tissue with a stratified squamous shape of the cells as well as a basement membrane on the bottom.
C. This slide represents muscle tissue because of the single nucleus and straight muscle cells.

E. This slide shows nervous tissue and the dendrites that carry signals towards the cell body.
Bone Basics Lab:
Microscopic Bone Anatomy
Write the function for these bone tissue structures.
1. The function of the Bone Canaliculi is to carry nutrients, oxygen, and CO2 towards and away from Osteocytes.
2. The function of the Central Canal is to transport blood vessels, nerves, and lymph through the bone and rungs parallel to the length of the bone axis.
3. The lamellae function is for strengthening and reinforcing bone and tissue.
4. The function of the Lacune is to contain cartilage and bone cells.
Define these terms.
Osteoclast- A bone cell that resorbs boney tissue, used in the maintenance and repair of bones.
Osteoblast- Cells with single nuclei that synthesize bone
Osteocytel- A star shaped cell found in mature bone to maintain structure as well as carry nutrients.
Skeleton Palpating
Zygomatic bone and arch
Your personal bones.
I guess I didn’t realize until now that I am mostly unfamiliar with all my bones. I broke my clavicle once and then re fractured it a few weeks later so I am slightly familiar with that bone. I know that it is a long thin bone that runs along the top of the shoulder. I am pretty sure it is attached to the rib cage and it is also attached the the scapula. I learned in this assignment that it attaches to the sternum. The bone helps to rotate the shoulder. I know that it is a hard bone to treat when broken because it is a hard spot to put a cast over so I just had to wear a sling until it healed.
A bone or groups of bones that I am unfamiliar with and would like to learn more about is the spine and skull. I have heard a bit about the skull from my chiropractor. From what I remember the the skull has plates that can shift around and are known as the temporal, frontal, parietal, and occipital lobe. There is also a couple bones called the zygomatic and sphenoid that sit basically in the middle of the head and can even be moved through a procedure called bilateral nasal specific. I believe that the skull attaches to the spine by a bone called the cranium.
You wrote an outstanding lab report. Also, the formatting is straight and easy to read :-).
