Investigation Of Tissues Essay

Investigation of Tissues

Tissues are defined as a group of associated, similarly structured
cells that with their ground substance act together in the performance
of a specialised function for the survival of the multicellular
organism. The tissues are classified into four main groups which are
epithelial, connective, muscle and nervous.

(http://encarta.msn.com/encyclopedia accessed 08 October 2004)

Epithelial Tissues

Epithelial tissues form the covering of all body surfaces with the
functions being to provide protective covering, absorption, secretion,
diffusion, sensation and contractility. They are tightly packed
together with little intercellular matrix and can be squamous
(flattened or scale like), cuboidal (cube), or columnar (cylindrical
or column like) in shape and may be arranged in single or multiple
layers.

I have chosen to look more into Ciliated Columnar Epithelium;

This is a tall column like cell with a nucleus at the bottom near the
basement membrane, with cilia and lots of cytoplasm above the
nucleus. Examples of where this can be found are in respiratory
tracts and the fallopian tubes. The cilia move together in a wave
motion so mucus and other foreign particles are expelled. Goblet
cells are usually present for mucus production. Towards the fimbriate
end of the ovaries it is ciliated in order to pass the eggs through
the fallopian tubes although closer to the uterus area it is
non-ciliated due to that area being more for secretion. The numbers
of these two types of epithelium varies according to the time during
the menstrual cycle.

(ARMSTRONG, K AND JACKSON, S. (1972) Anatomy and Physiology for
Nurses)

Connective Tissues

These tissues are responsible for cushioning, supporting and
maintaining form within the body and are found all over the body
linking and supporting organs. Connective tissue examples are;
adipose (fatty tissues), loose connective tissue, dense fibrous
connective tissue, elastic connective tissue, cartilage, osseous
tissue (bone), tendons and ligaments.

I have chosen to look more at adipose (fatty tissue):

Adipose is a specialised type of connective tissue which stores
lipids. It collects in large numbers and is shaped to be large round
or oval cells. Adipose has a similar function to that of fibrous
tissue, which throughout the body connects by irregular network of
strands to form a cushion layer to support blood vessels, nerves and
other organs.

Adipose is essential for insulation due to its low thermal capacity
which allows the body to retain heat, thus functioning normally. Its
other vital function is that of protection of delicate organs such as
the eyes and kidneys. Fat cells offer this by forming liquid and
being excellent at absorbing pressure as they cannot be flattened.

Although teeth can develop from either endoderm or mesoderm, in mammals neural crest and ectodermal tissues produce ectodermal appendages, which later grow as teeth
