Muscle Tissue Research Paper

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.

48) All epithelia have two surfaces, an apical surface and a basal surface, that differ in both structure and function. TRUE

Epithelial are the lining of internal and external surfaces and body cavities, including tubes/channels (ducts) carrying secretions from glands. Epithelial tissues can be made of several layers of cells (called compound epithelia), or a single layer known as simple epithelia. The lowest layer of cells is attached to the basement membrane for support and connection. Part of the basement

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.

There are three types of muscle tissues in the human body: skeletal, smooth and cardiac muscle. Skeletal muscles are striated muscles that attach to the bone by tendons and permit movement. Skeletal muscles promote movement by contracting and relaxing in response to voluntary messages from the nervous system, deeming skeletal muscles, the only voluntary muscles in the human body. Smooth muscles are involuntary muscles found inside the walls of the stomach,

The epithelium-connective tissue interface is the borderline where the connective and epithelial tissues meet. In the body it is most frequently to fine the connective and the epithelial tissues meet in an irregular or curvy way. The purpose of the irregular interface between these two tissues is to enhance adhesion and to provide

around. Each type of muscle does different things. “Your body has three types of muscle tissue-

Evaluate the types of epithelial and connective tissues found in the epidermis and dermis of the skin in terms of anatomy and functions.

Cardiac muscle is found only in the walls of the heart. The function is to power pump action of the heart. Cardiac muscle is involuntary tissue muscle that never gets tired, it has similarities with skeletal muscle, it is striated and with smooth muscle, its contractions are not under conscious control, this type of muscle is highly specialised. It is under the control of the autonomic nervous system. In cardiac muscle, without nervous input, contractions cannot occur due to cells called peacemaker. Cardiac muscle is highly resistant to fatigue due to presence of a large number of mitochondria and a good blood supply that allows continuous aerobic metabolism.

Collagen benefits active sportsmen and women by maintaining the strength of connective tissues in their joints. The ends of the bones are covered by a layer of cartilage, which acts as a durable lubricated pad to protect the bones as they move against each other with the movement of the muscles. Cartilage is in fact a mixture of water and collagen.

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

Tissues are primarily composed of cells and extracellular matrix. Cells are the biological building blocks of tissue. They maintain the function of the tissue by synthesizing proteins or metabolizing waste. Single cells communicate with one another and respond to stimuli in their surrounding environments. Cells secrete and maintain extracellular matrix (ECM) which is the structural component of tissues. Cells interact with each other and the ECM through direct contact as well as soluble signaling molecules, including cytokines, growth factors, hormones, steroids, enzymes, and other chemicals. These signals stimulate a chain reaction or cascade which alters cell behavior, both in the releasing cell itself, as well as other neighboring cells. Cells and structural matrix (for example, cardiomyocyte) are organized to function together as a tissue (e.g.,
