Intro + classification Flashcards
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
