connective tissues

tissues with a variety of functions including support, protection and partitioning around and within body structures. Different types vary from delicate networks to tough bands and sheets. All have cells within some type of matrix, which they form, and which may be mainly fibrous, cartilaginous, bony or fluid. Bundles of white collagen fibres (containing the protein collagen), strong and only slightly extensible, provide a supporting network in organs and tissues everywhere in the body (except the central nervous system) and in the sheaths and membranes that surround or separate them, form the basis of tendons and ligaments and are components of cartilage and bone. Extensible elastic fibres (containing the protein elastin) form networks, e.g. in the walls of arteries and in the lungs, and are a component of flexible cartilage (such as in the nose and ears); reticular fibres form delicate networks, e.g. in the skin deep to the epidermis, and in the walls of small blood vessels. The cells associated with all these fibres are known as fibroblasts or, when inactive, as fibrocytes . adipose tissue is a connective tissue with a fibrous stroma, widely distributed internally as well as subcutaneously; its cells, adipocytes, are closely related to fibrocytes; likewise the osteocytes in bone and chondrocytes in cartilage. Also classified as connective tissue are the various cells in the tissue interstices (e.g. macrophages) and in the blood.

But while laser is monochromatic and diffused, IPL, as its name implies, is more intense, which allows it to penetrate deeper into the skin to destroy not only the hair bulb, but also connective tissues around it, including stem cells.
If starfish body-wall connective tissues have mechanical mutability, they may contribute to the stiffening of the body wall through the stiffening of the dermis and the ligaments connecting the ossicles, thus making the ossicular framework less flexible.
