Muscle Tissue Research Paper

They are very strong, yet lightweight. Dense connective tissue, are cells crowded between collagen fibers. Loose connective tissue is the most common type of tissue in vertebrates. It holds the organs in place, and attaches to epithelial tissue. Reticular connective tissue is found around the liver, the kidney, the spleen, the lymph nodes, and in bone marrow. It forms a soft skeleton that supports. Blood is used to transport oxygen and nutrients to the cells.

58) Connective tissues that possess a large quantity of collagen fibers often provide the framework for organs such

• *Describe the 3 main types of cells and the 3 main types of fibers found in connective tissue? Reference Table 5.6.

The fibers in both cells are striated, and the fibers are long and each muscle cell is fused to one another. This is why so many nuclei are included. Also, the fibers are almost threadlike, with dark and light colored striations.

Tissues are groups of cells, which are placed together to achieve a common function. There are four main types of tissue: Epithelial, connective, muscle and nervous. Most of these tissues are found in our bodies, however the epithelial tissue is covered all over the surfaces of the body.

1-1: List the four types of tissue found in the human body and give an example of each.

Our bone tissues are made of a much harder substance than the cartilage, but they can be worn away by friction. They are tough on the outside, but on the inside they have a sponge-like design that helps to reduce the weight while retaining strength. They are designed to maintain the body’s structure and support the body’s movement and are used to protect weaker tissues, such as the brain, lungs and heart.

Identify the major surface muscles located in the body. Where are the orgins and insertions of these muscles? List the intended actions as well as an exercise or movement for each. A minimum of fifteen muscles is required.

List the four types of tissue found in the human body and give an example of each.

The matrix of a tissue can be secreted by the connective tissues within the body. The functions of connective tissues are to transport materials around the body to give support to the weak areas to protect and support the body.

Muscle tissue - Muscle cells are the contractive tissue of body that produce force and cause motion within internal organs. Muscle tissue is separated into three different categories: visceral or smooth muscle that are located in the inner linings of organs and skeletal

In this assignment I’m going to talk about the structure of the main tissues which are found within the body as well as what their role is in the terms of two named organs of the body. Tissues are a collection of similar cells that group together to carry out a specific function within the body. There are four different types of tissue found in the human body which include; epithelial tissue; connective tissue; muscle tissue and nerve tissue.

It is made of connective tissue, mainly areolar tissue which is tough and elastic, and contains white collagen fibrous connective tissue and yellow elactic connective tissue otherwise known as elastin. Collagen plumps the skin and elastin keeps it supple and elastic. Both of which diminish with age. The dermis contains eight main types of structure: 1) Specialised cells • Fibroblasts: responsible for the production of areolar tissue, collagen and elastin.

Visceral muscle is seen in the skin and walls of organs, such as the uterus, stomach, and intestine. Nervous tissue, which originates from the ectoderm, is seen in the central nervous system, or the brain and spinal cord, the peripheral nervous system, which is composed of nerves, and in all the body’s organs. Nervous tissue is composed of neurons and glial cells. Neurons create an impulse, which is sent between different areas, to respond to physical and chemical stimulations. Glial cells support neurons.

Connective tissue forms extracellular matrix (ECM): Consists of a mixture of proteins, polysaccharides, and in some cases, minerals.
