Structure & Function of Fascia Flashcards
What is fascia
1 type of connective tissue which envelopes, separates or binds anatomical structures
What 2 sub-divisions does fascia have
Superficial fascia
Deep fascia (investing)
What is superficial fascia
‘Loose’ Connective tissue
-Varies in thickness + distribution
-Provides most of fat storage
Collagen & elastic fibres
-Form 3D meshwork of dense irregular connective tissue
What is deep fascia
Dense organised connective tissue
-Varies in thickness
Devoid (free from) adipose tissue
Where is fascia found
Throughout the body,
even though its described as discontinuous the distinct layers are connected
Where is superficial fascia found
Is a subcutaneous tissue- under the skin varying in thickness and distribution
Where is deep fascia found
Deep to superficial fascia (Just not in face)
Extends from internal surfaces to wrap around skeletal muscles or neurovascular bundles = INVESTING FASCIA
In limbs forms thick sheets separating muscles into 2 compartments= INTERMUSCULAR FASCIA
What are general fascia functions
Packaging, wrapping + insulation of material
What is fascia active in
Thermoregulation
Protective padding
Support for tissues / organs
Reduces friction between tendons
Transmits mechanical force
Proprioceptive feedback
- Body mechanics to CN
Myofascial system
- Muscle tissue & connective tissue
working together
What can intramuscular septa (thick sheets) play a part in
Contain & direct the spread of infections and tumours
What is compartment syndrome
Deep fascia creates enclosed compartments so with swelling and fluid build up
-Pressure increases in compartment
-Affects muscles + nerve function
What is needed to relieve the pressure from compartment syndrome
fasciotomy
Where does infection spread in fascia
Within fascial compartments, or in between fascial compartments
although deep fascia can prevent this spread as thick facial planes
What do cervical fascial planes connect
Base of skull to superior mediastinum (heart)
What musculoskeletal conditions arise due to fascia
Plantar Fasciitis of foot
Fascial Fibrosis of hand
-Fascial thickening & deposition
Myofascial pain syndrome
-Chronic or acute
-Pain originates from muscle & surrounding fascia, has trigger points of radiating pain
