1
Q

3 components of tissues?

A

Cells, ECM and fluid

2
Q

5 main cell types?

A
  • Connective tissue cells- fibroblasts, chondrocytes and osteocytes (bone)
  • Contractile tissue cells- skeletal, cardiac and smooth muscle
  • Haematopoietic cells- blood cells, immune cells and bone marrow cells
  • Neural cells- neurones and glial (support) cells
  • Epithelial cells- Cell forming continuous layers
3
Q

4 types of tumours?

A

Carcinomas
Sarcomas
Lymphomas/leukaemias
Neuroblastoma/gliomas

4
Q

Two main criteria of epithelial classification

A

Their shape and layering

5
Q

Two facts about single squamous epithelium?

A
  • Form a thin epithelium for exchange to occur.

- Found in alveoli and endothelium lining in blood vessels

6
Q

single cuboidal epithelium?

A

Found in linings of ducts

7
Q

Simple columnar epithelium?

A

Found in surfaces involved in absorption and secretion of molecules

8
Q

Two types of stratified squamous epithelium?

A
  • Keratinizing- Epithelial cells which produce keratin and in doing so die becoming thicker and more protective structure like skin epithelium
  • Non-keratinizing- do not undergo keratin, epithelium lining mouth, oesophagus and anus
9
Q

Pseudo-stratified epithelium?

A

Look stratified but all cells have contact with the basal laminae
