Elastic fibers give elasticity to tissues and organs. Create your account. It has three types of fibres. Bone is a mineralized connective tissue that exhibits four types of cells: osteoblasts, bone lining cells, osteocytes, and osteoclasts [1, 2].Bone exerts important functions in the body, such as locomotion, support and protection of soft tissues, calcium and phosphate storage, and harboring of bone marrow [3, 4].Despite its inert appearance, bone is a it helps in repair of tissue after an injury. It is present in the vessels called lymph vessels. Name the connective tissue which helps in the repair of tissues. Common. Furthermore, they perform the function of transportation of For Example: Bone to bone, Muscle to bone or tissue. The fibers give the tissue strength, elasticity, and flexibility.These cells also release modified polysaccharides, which collect between cells and fibers and serve as a matrix (ground substance). As the name suggest connective tissue is a tissue that connects the different cell and structure of the body. Yellow fibres are thick straight elastic branched occuring singly formed of protein elastin.

Connective tissues are most abundant and widely distributed in the body of complex animals that surround many organs. Connective tissue is made up of cells, fibers, and a gel-like substance. The human body is made up of billions of cells that work together to execute numerous jobs. The function and types of connective tissues depend on the nature of the This kind of tissue is formed when multiple layers of squamous epithelium are arranged in a pattern. In this manner, irregular dense connective tissue may counterbalance multidirectional Question 6: What are the structural proteins that are secreted by cells? Salmonella is a genus of rod-shaped (bacillus) Gram-negative bacteria of the family Enterobacteriaceae.The two species of Salmonella are Salmonella enterica and Salmonella bongori. The orientation of fibers produces a regular or irregular pattern, resulting in dense regular and dense irregular tissues. Specialised Connective Tissues. i) The irregular pigmented cells (chromatophores or melanophores) contain yellowish-brown, black or blue melanin pigment granules.ii) This tissue is present in the choroid, ciliary body and iris of the eye and dermis of the human skin.Function: It provides colour to the structures.

The primary function of dense connective tissue is to protect the body from mechanical stress. The other classification scheme divides connective tissue based on the arrangement and amount of cells and fibers. Connective tissue is found deep and in-between the other three types of tissue: epithelium, nervous, and muscle tissue. What is the function of connective tissue class 9? The adipose tissues main function is to store energy in the form of fat. Soft connective tissues, as well as specialized forms such as cartilage, bone, fat, and blood, are examples. Collagen fiber is mostly found in dense connective tissue. They accumulate in high number in cases of allergic reaction and parasite infection. Mesenchymal connective tissue is pale staining and has few fibers and more cells. Non-embryological connective tissue includes loose connective tissue, dense irregular connective tissue, dense regular connective tissue, and elastic connective tissue,. 's' : ''}}.

Loose Connective Tissue. When cilia is present on these cells, they form ciliated columnar epithelium like those present in the respiratory tract. Types of Muscle Tissue Skeletal Muscle Tissue. There are three types of connective tissues: Question 3: Write about loose connective tissue? They are present in the lining of oesophagus and mouth. Animal tissue types include epithelial tissue, connective tissue, muscular tissue and nervous tissue. 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. The main function is binding ,supporting and packing together They have a segmented nucleus with granules that stain neutral.
