Name the tissue

What is the purpose of nervous tissue?

I am a single layer of cube-like cells that are found in the tubules of the kidneys; my job includes excretion and absorption.

I am a single layer of tall cells with round or oval nuclei; I can be found in the linking of the digestive tract and my job includes absorption and secretion of enzymes

I am made of many layers. The cells in my layers can be described as flat or squished. I can be found on your very arm as I am what makes up most of the epidermal layer of your skin!

I am arranged in several layers like stacks of cubes. I can be found in the sweat and salivary ducts of humans and my purpose is to protect!

I am a gel-like matrix with all three fiber types. I also contain cells such as fibroblasts, macrophages, mast cells and white blood cells. I wrap and cushion organs as well as release immune cells when needed to fight pathogens. I play a huge role in inflammation responses as I hold the tissue fluid. I am found all throughout the body under the epithelial lining!

I am comprised of closely packed adipocytes. I provide reserve food fuel; insulate against heat loss, as well as acting as a padding to protect and support organs.

Parallel collagen fibers that are densely packed together. I am great for attaching muscles to bone. I also attach bone to bone. I can work under stressful conditions when pulling and pushing for movement.

I am a solid calcified matrix containing many collagen fibers. I support and protect! I provide levers for the muscles to act on; I store calcium and other minerals and fat. I have marrow inside for blood formation.

Long, cylindrical multinucleated cells; obvious striations. Voluntary movement locomotion. I am attached to bones and occasionally skin

Branching, striated, uninucleated cells that are specialized. As I contract I propel blood into the circulatory system.

Spindle-shaped cells with central nuclei. There are no striations and the cells are closely arranged to form sheets. I am able to propel substances or objects along internal passageways and is controlled involuntarily. Found mainly in the walls of hallow organs.

These are branching cells that send electrical impulses and signals from the brain to the rest of the body.
