Histology: Muscle and Connective Tissue

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.

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

Compact bone looks dense and solid, yet it is filled with passageways that serve as conduits for nerves, blood vessels, and lymphatic vessels (Marieb, 181).

- Gross, or macroscopic, anatomy: Study of large body structures visible to the naked eye, such as the heart, lungs and kidneys.

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

12. What are the 3 types of cartilage and where would you find each type?

Tissues: Tissues are groups of similar cells that have specific functions. In this piece of work I’ll talk about these types of cells:

Based on color, the cartilage was whitish in color while the bone was cream colored. The cartilage was relatively more flexible than the bone. On composition, bone is made up of calcium while cartilage is made up of hyaline materials. Upon piercing with a knife, the bone is resistant to piercing. On application of more force, it cracks and breaks unevenly as compared to the cartilage that is less resistant to piercing and was cut clean through upon application of a relatively lesser

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.

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.

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.

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.

For many years, 3D computed tomography (CT) models were primarily used for the 3D reconstruction of human anatomy having taken over from radiographs due to the latter’s inability to reconstruct in 3D which was limiting both research and knowledge [4, 5]. CT models have the ability to rotate the reconstruction and can isolate specific anatomical sections, making them highly useful as a method for 3D reconstructions method. However soft tissues are not as visible as their osseous counterparts in CT [6].
