Connective Tissues

Definition

connects and joins the different parts of the body together.
The cells of the connective tissue are loosely packed and the space between the cells are filled with a jelly like matrix. (extracellular matrix)

is a hard and strong tissue.
It consists of cells which are embedded in a hard matrix containing calcium and phosphorus compounds.
Bone forms the framework of the body and supports the body and the main organs.

mineralized connective tissue made by bone-forming cells called osteoblasts which deposit collagen.
The matrix of collagen is combined with calcium, magnesium, and phosphate ions to make the bone hard.

Blood vessels and nerves are found at a central canal surrounded by concentric circles of osteons.

Spongy
- heads of long bones and inner layer of flat bones.
- strong but porous.
- also stores bone marrow.
Compact
- no visible spaces
- external layer of your bones
- stores calcium

in short for CTP.
made up of loose connective tissue that is found in the skin and fibrous connective tissue that is made up of collagenous fibers found in tendons and ligaments.

Dense Connective Tissues
- Ligaments
  - are flexible tissues which joins bones together and helps in movements.
- Tendons
  - are fibrous tissues which joins muscles to bones and helps in movements.
Loose Connective Tissues
- Areolar Tissues
  - fills the space between skin and muscles, inside the organs, around blood vessels etc.
  - It helps to repair the tissues.
- Adipose Tissues
  - is found below the skin and between internal organs.
  - It contains fats and helps to store fats.
  - This tissue is called adipocytes.
