Break down those connective tissues that we can't chew, so we could get to the meat.
Our muscle, nervous, and epithelial tissue types are more uniform, more obviously grouped together.
No matter how different a tendon, bone, or hunk of fat may appear, they are indeed very closely related.
<Loose vs. Dense Connective Tissue Proper>
Loose connective tissue have fewer fibers, and more cells and more ground substance.
<Types of Loose Tissue Proper: Areolar, Adipose, and Reticular>
Areolar Tissue is the most common loose connective tissue you have, found ALL over your body, just under your epithelial tissue, and wrapped around your organs.
It's got a loose and random arrangement of fibers, with just a few fibroblast cells that make those fibers.
Reticular tisssue is like areolar tissue, but with a woven mess of reticular fibers - rather than collagen and elastin fibers - hence the name.
This tissue provides the soft internal framwork, or stroma, of the spleen, lymph nodes, and bone marrow, and it supports lots of developing blood cells.
Your reticular tissue is what holds your blood in place in many of your organs.
<Types of Dense Tissue Proper: Regular, Irregular, and Elastic>
Your body has places that require more elasticity than rigidity, like say, around your joints.
Connective tissue proper is the most diverse group in this tissue family.
<Types of Cartilage: Hyaline, Elastic, and Fibro>
Cartilage Doesn't have any blood or nerves, and it stands up against both tension and compression pretty well.
Hyaline cartilage is your most common type - it's kind of glassy looking and provides pliable support.
It connects your ribs to your sternum and keeps the tip of your nose all perky.
Elastic cartilage is very similar to hyaline, but with more elastic fibers that are easier to see, and it's found in places where strength and stretchability are needed.
<Types of Osseous (Bone) Tissue: Spongy and Compact>
The word "bone" can refer to an entire organ - like your femur or scapular - or just bone tissue. And that bone, or osseous tissue, is just calcified connective tissue, perfect for supporting and protecting your body's various structures.
Spongy bone tissue is typically found in the heads of long bones and in the inner layer of flat bones like the sternum.
This spongy tissue is strong, but porous, even to the naked eye, and it uses this extra room to make and store bone marrow.
Compact bone tissue on the other hand is quite dense, with no visible spaces. It forms the external layer of your bones and stores calcium for bone cells to use to make more tissue.
<Blood is a Connective Tissue>
Blood is our fourth type of connective tissue.
In this case, the ground substance is your blood plasma, which has protein fibers floating around it.
Your blood's main job, of course, is delivering godds - it transports cells, and nutrients, and hormones, and wastes, and all kinds of other stuff, keeping all the parts of your body connected in the process.
Most of your blood cells are erythrocytes, or your famous red blood cells that zoom around, carrying oxygen and carbon dioxide through your body.
