Retiform lymphoid or adenoid tissue is similar to areolar, but a particular kind od cell, the lymphocyte, is present in very large numbers and forms the bulk of the tissue. The lymphocytes are held together by fine connective tissue fibres, These are like immature collagen fibres. Mucoid tissue is found in the umbilical cord, at birth, in the jelly of Wharton. It is also found in the adult in the vitreous humour of the eye. Adipose tissue . Adipose or fatty tissue is deposited in most parts of the body. It is associated with areolar tissue by the deposition of fat cells and is present in all subcutaneous tissue except that of the eyelids and the penis, and inside the cranial cavity. It consists of minute lobules of fat cells which are specially adapted to storing large droplets of fat. The substance contained in the cell is made up of compounds of fatty acid and glycerin. Adipose tissue has a very liberal blood supply; each lobule possesses a network of capillary blood vessels which closely surrounds the fat cells contained in it' Adipose tissue performs a number of functions; To help support and retain in position the organs of the body. It is well known that the kidneys, for example, are deeply embedded in fat. To form a protective covering for the body. To act as a store of material which when required can be re-absorbed and, by combustion in the tissues during metabolism, provide a source of heat and energy for the use of the body. | . |
