Lecture 9 - Connective Tissue, Cartilage Structure And Composition Flashcards
What are the 5 major types of connective tissue?
Bone, tendon, cartilage, derma and fascia
What are two types of specialised connective tissue?
Umbilical cord and kidney Cortex
Derma = and fascia =
Skin and membrane in the muscle (it is a thin casing of connective tissues that surrounds and holds every organ, blood vessel, bone, nerve fibre and muscle in place
What do all connective tissues have in common?
Few cells, and lots of the Extracellular matrix (fibres and ground substance)
What are some types of fibres?
Collagen and elastin
How are fibres arranged?
They are arranged in parallel or crisscrossed meshwork
What does elastin do?
It makes the tissues stretchy
Is elastin a protein?
Yes
What is found in the extracellular matrix?
Collagen and proteoglycans
What are the types of cartilage?
Hyaline, fibrous and elastic
Where do you find hyaline cartilage?
In your joints (articulating surfaces) has a white/blue colour
Where do you find fibrous cartilage?
In nearly all fibres, it is used for if you damage cartilage in your knee for example the body will repair with fibrous cartilage.
What is a problem with fibrous cartilage?
It is not reversible compressible whereas hyaline is
What happens if you put pressure on fibrous cartilage?
It will stay compressed - find this in the annulus fibrous (an invertebral disc)
Where do you find elastic cartilage?
In your ear lobes and epiglottis, it makes tissues stretchy
What does hyaline cartilage form?
Forms the distal end of ribs
Where is hyaline cartilaginous plates found?
Nasal septum, larynx, trachea and bronchi
What are hyaline cartilage both?
They are both firm and flexible
