Orbicularis oris muscle, also known as musculus orbicularis oris is a complex, multi-layered muscle which attaches through a thin, superficial musculoaponeurotic system to the dermis of the upper lip and lower lip and serves as an attachment site for many other facial muscles around the oral region. A: According to scientists, fat cells never really disappear. There are two types of fibre: slender yellow fibre that branches freely and connects up to form the elastic network, and wavy white fibres that are grouped in bundles and yield gelatin when boiled. The osseous tissue is relatively hard and lightweight in nature.5. How many types of connective tissue are there? The collagen fibres help in the repair of injured tissues. The thrombocytes, or blood platelets, are a large number of irregular cells that help in the clotting of blood. It is made up of bone cells called osteocytes. Fig: Specialised Connective Tissues: (a) Cartilage, (b) Bone, (C) Blood. It forms layers protecting the body and is therefore, more tightly packed together. Meknes | Fes; OZYL ; texas highways travel guide It form inter cellular substance between cells of different types of tissue, so that help in friction less movement of the body organ. In this manner, irregular dense connective tissue may counterbalance multidirectional pressures, whereas regular dense connective tissue can only do so in one direction (in the sense that its collagen fibers are parallelly orientated).

They form a cellular organizational level that sits in the middle of the cell and organ system hierarchy. What is connective tissue and its function?Ans: Connective Tissue is defined as a group of tissues that help in binding and supporting other tissues or organs of the body.Function: It helps in linking and supporting other tissues and organs of the body. These disorders can involve the joints, muscles, skin, the eyes, heart, lungs, kidneys, gastrointestinal tract, and blood vessels. The mesothelial cells are supported by a basal membrane in continuity with a thin layer of richly vascularized loose connective tissue, with lymphatics and fatty tissue, which is called the subserosa. Some bones create blood cells in their bone marrow. It also helps to bind together the cells of smooth muscles. Loose connective tissue is composed of cells and fibers that are dispersed in a semi-fluid ground substance, such as areolar tissue found beneath the skin layer. This indicates tendency to malabsorption and toxins in nutritive zone.
