Histology Flashcards
What are the 4 basic cell types?
Epithelial, Muscle, Connective tissues, Nerve
Epithelial cells structure (layers and shape)
- Simple or Stratified or Pseudostratified
- Squamous, Cubical, Columnar
Function of epithelial cells (3)
- Covers and protects
- Separates organs and body compartments
- Secretory + absorptive
Types of muscle (3)
- Skeletal (voluntary control)
- Cardiac
- Smooth (sustained + involuntary)
Muscle function (3)
Control orifices, regulates temperature, regulates blood flow
Connective tissue function
Support, protect, give structure to (gel-like substances)
Connective tissue in ligaments purpose
Really strong to hold joints together
Connective tissue in tendons purpose
Fibrous, attaches muscle to bone and transfers force from muscle to bone
Adipose tissue function
Energy storage, insulation, cushioning, heat generation
Neurones
Neural activity for automatic/ voluntary control
Glial cells (and their function)
Supporting nerve cells, hold neurons in place, protects and nourishes
Apical surface (epithelial cells)
Side facing lumen/ free space
Transitional epithelium shape and purpose
Diamond shape to be able to stretchhhh
3 types of connective tissue
Fibrous (fibre), Fibro-cellular (fibre + cells), matrical (hard)
Interstitial growth
- Happens in young animals
- Chondroblasts lay matrix + fibres
- They get trapped in lacunae in mature cartillage
