-There's also connective tissues like loose, areolar and adipose tissue! Do you know what connective tissue is for?
Connective tissues like loose areolar are located in the hypodermis, as it is a collection of loos, irregularly arranged cells that contain fibroblasts, collagen, and elastic fibers. These elements help to store lipids, produce white blood cells and secrete antibodies in response to infection
Connective tissues are used to connect, bind, and support body structure. They consist of cells, fibers, and ground substance (fluid, viscous sol/gel, or mineralized).
Not only that! But have you heard of nervous tissue? We're currently learning about it in class!
No, Mr. Johnson I haven't heard of nervous tissue...but I wanted to-
Nervous tissue consists of neurons which communicate w/ other neurons. By doing so, the cells (containing dendrites and an axon) are able to send electrical impulses that generate muscle contractions, environmental awareness, and other body activities! That's awesome right?!
-Let me tell you 'bout it! Nervous tissue is located in the brain, spinal chord and, of course, nerves!
That is pretty awesome but I-
-Oh wait! There's one more typ of tissue I haven't talked about yet! MUSCULAR TISSUE!
Skeletal cells are long, striated, and multi-nucleated. These cells make up vascularized cell muscles that greatly contribute to the size/shape of the body.
So, muscular tissue responds to nervous tissue signals. Muscle are obviously all around your body and consist of three types of cells: skeletal, cardiac, and smooth.
Cardiac cells are branched and striated, w/ either one or two central nuclei. They make up the heart muscle and are highly vascularized.
Oh! Also, smooth muscle cells are long, tapered, and are surrounded by a plasmalemma. They are obviously smooth and are less organized than a skeletal muscle. The make up the walls of organs and cavities and serve to allow powerful, rhythmic contractions.
