Simple Anonymous Essay

It is made up of either liquid, solid, or connective tissue, within the matrix there are many types of connecting fibres, such as collagen and elastic fibres.

The skeletal system is made up of cartilage and bone. Both bone and cartilage are connective tissues, that is, they are composed of cells in a matrix with intracellular fibers. Just imagine connective tissue as a gelatin salad with grapes and coconut. The grapes would represent cells, the gelatin the support material for matrix, and the pieces of coconut the intracellular fibers. By changing the amounts of each ingredient and adding extra substances, we can produce a material that is very hard like bone and can withstand weight or softer like cartilage which can be used as a cushioning material.

55) Which of the following substances would NOT be found in significant amounts in the extracellular matrix of the illustrated areolar connective tissue? Keratin

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.

In this exercise, we will examine a fresh raw chicken bone to study bone

3. Describe the primary functions of each type of body tissue and give examples of each.

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.

The basic function of the connective tissue is to support, bind or connect all other types of tissues together in the body.Blood, cartilage, and bone are usually considered as connective tissue

The second type of tissue found in the body is connective tissue. They lie beneath the epithelial tissue helping to connect different part of the internal structure, the cells are more widely separated from each other then in epithelial tissue. The intercellular substance known as the matrix is found in considerably large amounts. Within the matrix there are usually fibres which may be a jelly like consistency or dense and rigid depending on the type, function and positioning of the tissue. Theses fibres form a supporting system for cells to attach to. The major functions of connective tissue are to transport materials, give structural support and protection. The types of connective tissue that will be explained are blood, bone, cartilage, bone, areolar tissue and adipose tissue.

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

Bones are living tissues. They provide support, protect organs, contain multiple minerals, and store the marrow that creates cells for our entire body. Bones consist of compact bone, cancellous bone, osteoblasts, osteocytes, osteoclasts, osteoid, and inorganic salts. Compact bone is a dense bone tissue that makes up eighty percent of the human skeleton. It is made of primarily of inorganic salts, which produce bone hardness, and contains tiny spaces for osteocytes. Matured compact bone is layered, it contains vascular canals that provide necessary blood supply for osteocytes. Cancellous bone makes up the remaining twenty percent of the human skeleton. It is lightweight and porous, allowing small spaces for bone marrow and blood vessels.

The organisation of the body is cell, tissue, organ, system and within the body there are many types of tissues. The four main tissues within the body are: epithelial, connective, muscle and nervous tissue. Tissue is a group of cells which are similar to one another and carry out specific functions. In this report detailed explanations of the four main tissue types and where they can be located within the body.

Tissues are defined as groups of cells with a common structure and function. However, there are four different main categories in the human body: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Even within the four main categories, there are different types of cells assembled in a different formation. For example, the cells in the epithelial tissue are joined closely together with little material in between them. There are different types of epithelium tissues, including the simple epithelium and stratified epithelium. A simple epithelium has a single layer of cells and a stratified epithelium has multiple layers of cells. Just within the epithetical tissue, the cells connect to each other in a different structure

14. Using the key, choose the best response to identify the connective tissues described below. c a c f i b h d h i a 1. attaches bones to bones and muscles to bones 2. acts as a storage depot for fat 3. the dermis of the skin 4. makes up the intervertebral discs 5. forms the hip bone 6. composes basement membranes; a soft packaging tissue with a jellylike matrix 7. forms the larynx, the costal cartilages of the ribs, and the embryonic skeleton 8. provides a flexible framework for the external ear 9. firm, structurally amorphous matrix heavily invaded with fibers; appears glassy and smooth 10. matrix hard owing to calcium salts; provides levers for muscles to act on 11. insulates against heat loss

The skeletal system is made up of bones and joints. Bones are a dry dense tissue that is composed of calcium phosphorous and organic matter. The bones are protected and covered by a layer of fibrous connective tissue membrane called the periosteum (Brown, et al., 2015, p. 1547). There are two basic types of bone tissue: Compact Bone and Spongy Bone. Compact bones are dense smooth bones, while Spongy bones are composed of small needle-like pieces of bones and open space. Bones are then categorised according to the shape of the bone into four groups: long, short, flat and irregular. Long bones characteristically are typically longer then they are wide and generally have a shaft with heads at either ends e.g. the humerus. They are mainly compact bones. Short bones
