Simple Epithelial Tissues

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.

4. Organ level- Organs are made up of different types of tissues. Organ is a discrete structure composed of at least two tissue types that performs a specific function for the body.

types of muscle tissues : skeletal, cardiac, smooth. Each of these different tissues has the ability

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

The skin is divided into three different parts including the epidermis, dermis, and hypodermis. The epidermis is the outermost layer of the skin. This region of the skin has no blood cells or blood vessels running through it. All of the nutrients that the epidermis needs are received through diffusion from the dermis. The epidermis is made up of stratified squamous epithelial cells. The epidermis is made of five separate layers: the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and the stratum corneum. Starting at the innermost layer, the stratum basale is where mitosis of keratinocytes takes place. This layer of the epidermis also contains melanocytes which give the skin it’s pigment. As mitosis takes place in the stratum

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.

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

The three layers that make up healthy skin: Epidermis, Dermis and Hypodermis. Epidermis is composed of keratinized, stratified squamous epithelium. This layer provides a thick, water proof protective covering over the underlying skins. The dermis layer is composed of primarily of dense, irregular, fibrous connective tissue that is rich in collagen and elastin. The dermis contains blood vessels, nerve ending, and epidermally derived cutaneous oranges such as sweat glands, sebaceous glands and hair follicles. The last layer is Hypodermis this layer is composed primarily of loose dead skin. The fat layer provides cushioning and insulation for

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.

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.

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.

Stratum Granulosum is another shallow layer; it is made up 3 to 5 layers of flat packed grainy cells called kertaohylain cells which act similar to a water filter, to absorb any foreign bodies. This eases water loss and keeps up hydration in the skin.
