To recognise various components of connective tissue and understand their functions.
- To recognise the histological appearance of mesenchymal and mucoid connective tissue, and revise loose and dense fibrous connective tissue.
- To recognise adipose tissue (white and brown fat) and understand its functions.
- To recognise the histological appearance of the different forms of cartilage: hyaline, elastic and fibrocartilage.
- To understand the role of the perichondrium in the formation of cartilage, and the mechanisms of appositional and interstitial growth.
Examine the following virtual slides. Identify, draw and label the main features and note their function.
- CT - connective tissue
- Dense CT - connective tissue mainly occupied by fibres (dermis of skin).
- Loose CT - connective tissue mainly cells, vessels and nerves. Generates a soft and compliant CT (mucous connective tissue, reticular connective tissue and adipose tissue).
- irregular CT - fibres do not show a clear orientation within the tissue and form a densely woven three-dimensional network.
- regular CT - fibres show a clear parallel orientation within the tissue.
unilocular - single lipid drop in cytoplasm. Nucleus flattened on edge of cell.
|Mesenchyme forming cartilage||Endochondral ossification|
- Mesenchyme - is an embryonic (undifferentiated) connective tissue
- occurs in tissues where "flexibility" required
- histologically similar to hyaline cartilage with the addition of a elastic fibres
- elastic fibres - dense network of delicately branched fibres, individual fibres are difficult observe
- Examples - epiglottic cartilage, larynx (corniculate and cuneiform cartilage), external ear and auditory tube
Elastic cartilage (elastin stain)
- Transitional between dense connective tissue and hyaline cartilage
- merges into neighbouring tissues (tendons or articular hyaline cartilage)
- difficult identify the perichondrium
- Examples - joints (intra-articular lips, discs and menisci) and intervertebral discs.
- form short rows between dense bundles of collagen fibres
- lie singly or in pairs
- collagen type I
Electron Microscopy - Collagen
|Collagen Synthesis||Collagen is the major extracellular matrix protein found in connective tissues.
