Tissues (Mod 2 Lesson 1)

Epithelial Tissue: Stratified Squamous
Stratified squamous epithelial tissue is flat and scale-like, and contains stacked layers. The function of stratified squamous epithelial tissue is to help protect from abrasion or rubbing. The form of stratified squamous epithelial tissue relates to its function because the stacked layers and tightly packed cells create a protective barrier that allow the tissue to protect from abrasion.
Connective Tissue: Bone
One type of connective tissue is bone. Bone is the most rigid type of connective tissue and has the same strength as cast iron. It is surrounded by marrow tissue and contains many minerals and fibers. The structure of bone relates to its function heavily because the strong structure of this tissue allows it to support the framework of our body, as well as protect our organs.
Muscular Tissue: Skeletal
Skeletal muscle tissue is striated, has elongated cells, and is voluntary. Skeletal muscles tissue are found in large body muscles, such as biceps or hamstrings. The structure of this tissue relates to its function because the striated structure results in extra strength for the voluntary muscle that pulls on bones, which ultimately allows movement.
Nervous Tissue
Nervous Tissue is located in the brain, spinal cord, and peripheral nerves that branch throughout the body. It is composed of nerve cells called neurons, which are bound together by connective tissue. The structure of nervous tissue relates to its function because, the neurons that nervous tissue is composed of conduct impulses and allow the nervous tissue to generate and transmit nerve impulses to and from body organs.
Epithelial Tissue
Epithelial tissue is found throughout the body; it covers the inside and the outside body surfaces, including organs. Its functions include protection, absorption, filtration and excretion, and sensory perception. Epithelial tissue is the best type of tissue to be used in its specific locations and to perform its particular functions. One example of how epithelial tissue is the best tissue for its particular location is, the outside surface of our bodies, skin. The skin protects our bodies from physical and chemical injury, and microbial invasion. Epithelial tissue is the best tissue to perform this function because epithelial cells pack tightly together and perform a protective barrier. Epithelial tissue is also the best particular tissue because the cells in epithelial tissue reproduce rapidly, which allows the tissue to fix itself quickly; if a person gets a skinned knee or sunburned the tissue repairs itself rapidly.
