Module Two Lesson One Assignment

Tissue's

Epithelial

The epithelial tissue is packed tightly together to form a protective barrier. The epithelial cell absorbs nutrients from connective tissue to which it is attached underneath. The functions of epithelial tissue are to protection, absorption, filtration, and sensory perception. There are 3 different shapes; squamous, cuboidal, and columnar. Simple squamous is one thick cell, forms a solid layer of cells which line blood vessels and organs. Stratified squamous is multiple layers thick and forms the epidermis, lines the body cavities (mouth, and the outer layer of the skin). Simple cuboidal is found in the lining of the kidney tubules and gland ducts and its function is secretion and reabsorption. Simple columnar is one cell thick, found in the lining of the digestive track. Stratified columnar is quite rare found in portions of the larynx. Pseudostratified columnar is ciliated. Transitional epithelium is mainly found in the bladder, ureters of the urinary track, it can stretch or change.

Connective

A connective tissue consists of living cells and non- living substance, various consistencies (fluid, solid, gel-like or very hard), gives the tissue its density. Connects binds and support structures (tendons and ligaments), wraps around organs and protects and cushions them, bear weight, stretch, and take abuse, insulates and fills space and stores fat, transports nutrients and other substances through the body, the supporting framework of our body and protects our organs. There are 5 different kinds of connective tissue; bone, cartilage, dense then loose connective tissue, and blood. The function of bone is it provides protection and support, and stores minerals and is a site of blood cell production. There are 3 types of cartilage; hyaline, elastic, and fibrocartilage. Hyaline covers the end of bones and joints, supporting respiratory passages (trachea). Elastic is found in the larynx (voice box) and the outside of the ear, flexible and elastic. a. Fibrocartilage is tough, having a large number of collagenous fibers, found in the discs between the vertebrae. Dense regular connective tissue is regularly arranged bundles packed with fibers running the same way in one direction. Dense irregular connective tissue is irregularly arranged bundles, with fibers running all directions. There are 3 kinds of loose connective tissue; areolar, adipose, and reticular. Areolar is a loose arrangement of cells and fibers, cushions organs and holds them together. Adipose appears empty, storehouse energy and functions to protect and insulate. Reticular is a delicate network of fibers and cells, located in lymphoid organs (spleen, bone marrow, and lymph nodes provide an internal supporting framework for the lymphoid organs.

Nervous

The nervous system is made up of the brain, spinal cord, and nerves. The nervous system controls your whole body. The function of the nervous tissue is to generate and transmit nerve impulses to and from body organs. The brain controls everything that we think and receives the signals from different parts of our body. the spinal cord provides support it also helps send the signals to the rest of the body. The nerves are what sends the signals and they are passed between the nerves.

Muscular

There are three different kinds of muscles; skeletal, smooth, and cardiac. The function of skeletal is to provide movement and support and it is found in large body muscles (biceps). Skeletal muscles are voluntary. The function of smooth muscle is to move blood, food and waste through the body and is found in organ walls and blood vessel walls. Smooth muscles are involuntary. The function of cardiac is to make the heart beat and is only found in the walls of the heart. Cardiac muscles are involuntary.

Tissue that is best for it's location.

I think the tissue type that is best for its location is the nervous system. I think the nervous system because the nervous system controls our whole body. The nervous system includes the brain, spinal cord, and all the nerves. The brain controls everything that we think and receives the signals from different parts of our body. the spinal cord provides support it also helps send the signals to the rest of the body. The nerves are what sends the signals and they are passed between the nerves. The nervous system is the main control board of our body and without that, we couldn't do anything.
