Q

What is the purpose of connective tissue ?

A
  1. supports and binds structures together
  2. protects against compressive, shearing and tensile forces
  3. helps with distribution of nutrients
  4. removes broken down cells and foreign bodies
  5. stores iron to be used in hematopoiesis
  6. insulates and acts as a cushion (fat)
  7. provides a pathway for nerves
  8. prevents the spread of infection
  9. allows for movement
  10. allows for growth
  11. supports posture

Q

what is the innervation of connective tissue proper

A

propriocepters (position)
nocioceptors ( pain)
pacinian corpuscles (pressure) reduce function to protect the joint
golgi corpuscles (stretch sensation

16
Q

pacinian

A

pressure ( reduce function to protect the joint)

17
Q

proprioceptors

A

monitor position and function
when ligament proprioceptors are stimulated they produce an inhibitory response in muscle activity and protect the muscle

18
Q

nocioceptors

A

monitor pain

19
Q

pacinian corpuscles

A

pressure receptors

20
Q

golgi corpuscles

A

stretch sensation

21
Q

composition of ligaments

A

dense regularly arranged fibrous connective tissue

22
Q

action of ligaments

A

passive restraints that limit extreme joint movement with the aid of muscles

23
Q

what DONT ligaments do

A

they dont keep articular surfaces together or maintain joint postion on muscles can do that

24
Q

how can a ligament be damaged

A

-strain
-laceration
-detachment

25
Q

continued microtrauma induces what in ligaments

A

-elongation
-looseness
-other degenerative changes

26
Q

articular ligaments do not have what?

A

articular ligaments do not have any elastic fibers

27
Q

what happens when ligaments are overstretched?

A

they do not return to their original length and this causes laxity of the joint

28
Q

two accessory ligaments of the mandible

A

sphenomandibular
stylomandibular

29
Q

what are the functional ligaments of the tmj

A

capsular ligament
discal ligaments (medial and lateral)
temporomandibular ligament

30
Q

capsular ligament

A

-vascularized and innervated
-surround the joint and allows containment of fluid , the TM ligament and the discal ligaments

31
Q

The capsular ligament acts to do what ?

A

resist any medial,lateral and inferior forces that tend to seperate or dislocate the articular surfaces
