Q

Name the 2 Types of Dense connective tissue

A

Dense regular
Dense irregular

17
Q

What is the role of Dense Regular Connective Tissue

A

Provides strong attachments between structures
Provides great tensile strength in 1 direction

18
Q

What is the structure of dense regular connective tissues

A

Collagen fibres in parallel bundles
A few elastin fibres

19
Q

Give examples of Dense regular connective tissue

A

Ligaments - bone to bone - stabilise joints
Tendons - muscles to bone - transmits tensile load form muscle to bone

20
Q

What is the role of Dense irregular connective Tissue

A

Provides strength in multiple directions, holds muscle together and separates muscles into functional groups

21
Q

What is the structure of Dense irregular connective tissue

A

Collagen fibres randomly arranged, a few elastin fibres

22
Q

Name 2 examples of dense irregular Connective Tissue

A

deep fascia - sheet of connective tissue surrounding and protecting muscles
Joint Capsule - envelope surrounding synovial joint
