In response to cold or stress, your fingers or toes might turn white and then purplish blue. The ciliary body is a ring-shaped thickening of tissue inside the eye that divides the posterior chamber from the vitreous body.It contains the ciliary muscle, vessels, and fibrous connective tissue.Folds on the inner ciliary epithelium are called ciliary processes, and these secrete aqueous humor into the posterior chamber.The aqueous humor then flows through the pupil into the . As the name implies, connective tissue serves a connecting function: It supports and binds other tissues in the body. Connective tissues develop from the mesodermal cells of the embryo. It is the most abundant and widely distributed tissue in the body. Specialised Connective Tissues. As the name implies, regular elastic dense connective tissue provides elastic characteristics to the organ in which it is found, allowing it to stretch and generate a certain degree of flexion when coupled with rigid parts. Reinforcing joints also strengthen and supports the articulations connecting bones. Lacunae are niches that contain bone cells (osteocytes).

Bone, cartilage, fat, blood, and lymphatic tissue are all examples of connective tissue. Choose all that apply. 1 The thickness of this subcutaneous layer varies throughout the body and also from person to person. Collagen fibers are found in rows between several antiparallel bundles of fibers in dense regular connective tissues. It is the primary tissue that supplies the body with structural support. Connective tissue performs the following major functions: 1.Enclosing and separating other tissues. CONNECTIVE TISSUE PROPERTIES The functions of various connective tissues are to bind cells together to form and organize tissues, organs, and systems and to provide a mechanical link between musculoskeletal junctions and the articulations of joints. (c) The sub-cutaneous adipose tissue acts as shock absorber, e.g. It may surprise you to learn that all sophisticated animals are made up of only four fundamental types of tissues.
