P2 - The four main tissues.
• Epithelial is layers and linings of the skin
e.g. legs, inside the mouth this is lining of
skin around organs.
• This tissue can also be the membrane
lining and help to keep the organs and
body separate to keep them in place and it
will also protect them aswell.
• Muscles is cells that are specialised to
contract and move parts of the body.
Muscle tissues are in the heart, both
intestines and liver all these are muscles
that the person does not have power over.
• There are different types of muscles these
are smooth and rough, slow and fast,
twitch and voluntary and involuntary.
• Connective tissues hold structures
together and provide support, there are
many different connective tissues.
• Connective tissues are one of the only
tissues that does not have blood going
through the tissue.
• Examples of connective tissue are the
inner layers of skin, tendons, ligaments,
cartilage, bone and fat tissue.
• Nervous tissues are all over the body, it is
also things you can feel. There is two
types of nervous tissues these are
neurons and glial cells.
• Nervous tissues sends signals around the
body to make it move. The signals come
from the brain they are then sent down the
spine then to the body, then the body acts
in which ever way the signal is sending it.
