1
Q

What type of joint is TMJ

A

atypical synovial

2
Q

Classification of the TMJ

A

compound hinge and gliding

3
Q

What are the articular surfaces covered by in the TMJ

A

fibrocartilage instead of hyaline.

Fibrocartilage is more resistant to damage and can regenerate

4
Q

What bones formed the TMJ

A

condyle of the mandible, mandibular fossa and arituclar eminence of the temporal bone

5
Q

What is the innervation for the TMJ

A

Auriculotemporal, deep temporal, and masseteric branches of CN V3

6
Q

Shoulder (glenohumeral) joint type, classification, and bones involved

A

Type: synovial
Classification: Ball and Socket
Bones involved: Glenoid fossa head of humerus

7
Q

Innervation of the shoulder joint

A

axillary and suprascapular nerves

8
Q

Sternoclavicular joint type, classification, and bones involved

A

Type:synovial with an intra-articular disc

Classification: Saddle (sellar) but behaves like a ball and socket and is covered with fibrocartilage

Bones involved: Manubrium of sternum and medial head of the clavicle

9
Q

Innervation of the sternoclavicular joint

A

medial branch of the supraclavicular nerve (C3) and nerve to subclavius

10
Q

Elbow joint type, classification, and bones involved

A

Type: synovial

Classification: Hinge (ginglymus)

Bones involved: Lower end of humerus and head of the radius and trochlea of the ulna

11
Q

Innervation of the elbow joint

A

radial and musculocutaneus nerves

12
Q

Proximal and distal radiu-ulnar joints type, classification, and bones involved

A

Type: synovial

Classification: Pivot (trochoid)

Bones Involved: Head of radius and radial notch of the ulna (proximal) and head of ulna and distal end of radius (distal)

13
Q

Innervation of radio-ulnar joints

A

median, ulnar, and radial nerves

14
Q

Wrist joint type, classification, and bones involved

A

Type: synovial

Classification: Condyloid (ellipsoid)

Bones Involved: distal end of radius, scaphoid, and lunate bones

15
Q

Innervation of wrist joint

A

radial, median, and ulnar nerves

16
Q

1st carpometacarpal joint type, classification, and bones involved

A

Type: synovial

Classification: Saddle (sellar)

Bones involved: Trapezium and 1st metacarpal

17
Q

Innervation of 1st metcarpal joint

A

radial and median nerves

18
Q

Metacarpophalangeal joint type, classification, and bones involved

A

Type: synovial

Classification: condyloid (ellipsoid)

Bones involved: head of metacarpal and base of proximal phalanx

19
Q

Innervation of metacarpophalangeal joint

A

median, ulnar, and radial nerves

20
Q

Hip joint type, classification, and bone involvement

A

type: synovial
classification: ball and socket

Bone involvement: head of femur and acetabulum of os coxae

21
Q

innervation of the hip joint

A

femoral, obturator and nerve to the quadratus femoris

22
Q

What is the intra-articular ligament of the hip joint called and what it contains in children

A

round ligament of the head of the femur: contains the central foveolar artery in children (absent in adults)

23
Q

What are the three extra-articular ligaments of the hip joint called and their functions

A

iliofemoral: prevents hyperextension
pubofemoral: prevents hyper-abduction

Ischiofemoral: prevents hyperextesion

24
Q

Knee joint type, classification, and bones involved

A

type: synovial
classification: modified hing (ginglymus)

Bones involved: lower end of the femur and upper end of tibia

25
Q

Innervation of the knee joint

A

femoral, tibial, and common peroneal nerves

26
Q

What are the two intra-articular ligaments of the knee and their function

A

Anterior cruciate ligament: Origin - anterior part of the intercondylar ridge, insertion - posterior side of the medial aspect of the lateral condyl of the femur, it prevents anterior movement of the tibia on the femur

Posterior cruciate ligament: origin - posterior part of the intercondylar ridge, inserts - anterior part of the lateral aspect of the medial condyle of the femur, prevents posterior movement of the tibia on femur

27
Q

What are the two extra-articular ligaments and their function

A

medial collateral: thick, attaches to medial meniscus, prevents abduction

lateral collateral: thin, prevents adduction

28
Q

What are the two intra-articular discs and their function

A

medial meniscus: semilunar fibrocartilaginous disc, attached to MCL and the intercondylar ridge

Lateral meniscus: nearly circular, NOT attached to the lateral collateral ligament (unlike medial with MCL)

29
