Nervous Tissue Connective

Most types of connective tissue contain fibrous strands of the protein collagen that add strength to connective tissue. Some examples of connective tissue include the inner layers of skin, tendons, ligaments, cartilage, areolar, adipose bone and fat tissue. In addition to these more recognizable forms of connective tissue, blood is also considered a form of connective tissue.

Skeletal Muscle Structure.The cells of skeletal muscles are long fiber-like structures. They contain many nuclei and are subdivided into smaller structures called myofibrils. Myofibrils are composed of 2 kinds of myofilaments. The thin filaments are made of 2 strands of the protein actin and one strand of a regulatory protein coiled together. The thick filaments are staggered arrays of myosin molecules.

The nervous system is made up of basic units called neurons. The main role of the neurons is to receive, integrate and transmit information throughout the body. There are some neuroglial cells found in nervous system aswell which provide support to the neurons by giving protection and nourishment Neurons have nerve processes that looks like finger like projections extended from the nerve cell body. They also contain axons and dendrites which enable them to transmit signals throughout the body. Normally, axon carry signals away from the cell body and dendrites carry signals toward the cell body according to Regina Bailey (2013). Neurons have three different shapes: bipolar, unipolar and multipolar where bipolar has two neuronal processes coming out of the cell body, unipolar has only one neuronal process coming out of the cell body and multipolar has many neuronal processes coming out of the cell body.

and connective tissue. Although an organ has a specific function, organs also function as part of

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

There are three main types of muscle tissue in the body: Skeletal muscle, smooth muscle and cardiac muscle. Firstly, skeletal muscle has a stripped appearance when it is examined under a microscope so it is sometimes known as striated/stripped muscle. Skeletal muscle is voluntary and this means that it is under conscious control. Secondly, there is smooth muscle which is an involuntary muscle that operates without any conscious control. This muscle is controlled by the nervous system. Smooth muscle can be found in the blood vessels and the walls of the digestive system and it helps to control digestion and blood pressure. Lastly, there is cardiac muscle which is located in in the wall of the heart. Cardiac muscle is involuntary and this means that it is not under conscious control. This is made up of a specialised type of tissue which is striated and it has its own blood supply. The contractions aid the pumping of blood through the blood vessels

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.

Connective tissue - Connective tissues holds and binds everything together which are found all around the body. This type of tissue is also called fibrous connective tissues as they are consisting of a lot of fibres eg. Collagen and Elastin.

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.

The Central nervous systems include the brain and spinal cord which transfers voluntary nerve impulse to skeletal muscles, skin, muscles, and glands.

When cells are grouped together they form what is known as a tissue. Different types of tissue make up different types of organs. The 3 main types of tissue are Muscular, Nerve and Epithelial. The muscular tissue is made up of three forms, they include the skeletal, smooth and cardiac tissues.

Muscle is formed with a long and thin tissue called muscle tissue which moves the organs and organisms, and the muscle tissue is made out of a group of cells called the muscle fibers. There are three types of muscle: skeletal muscle, smooth muscle, and cardiac muscle. Skeletal muscle is the muscle who moves the bones, it has much longer fibers than the smooth muscles. Smooth muscle forms the walls of organs, for example, the wall of a stomach. Cardiac muscle is the muscle that forms the heart. From the cross-section view of a muscle, it shows that there is a layer of muscle sheath around the outermost layer of the muscle. The blood vessels that brings glucose and oxygen to the muscle are weaved in the fibers, and there is a layer of epithelial cells around the muscle to keep the fibers together.Muscle tissue can repair itself, but with round scar tissue instead of long, stretchy fibers. Skeletal

There are the Smooth, the Skeletal, and the Cardiac muscular tissues. Smooth muscles are made of spindle-shaped cells.
