44
Q

Describe the normal anatomy of the TMJ.

A

The TMJ is a synovial modified hinge joint found between the head of the mandible and mandibular fossa of the temporal bone. Between these two articular surfaces is a fibrocartilaginous joint.

45
Q

What muscles are involved in the TMJ? Indicate what movement they produce.

A
  1. Lateral pterygoid - protrusion and opening of the mouth
  2. Temporalis - close the mouth and retraction of the jaw
  3. Masseter - close the mouth
  4. Medial pterygoid - close the mouth
46
Q

How does the clicking sound and pain stem from in the TMJ?

A

The clicking sound often arises from the displacement of the disc anteriorly. Often caused by a lateral pterygoid strain. The disc has no vascularization or innervation so when it is in the right place, no pain would arise.

47
Q

What are the roots of the ulnar nerve and which trunk is this a part of in the brachial plexus

A

The ulnar nerve arises from C8 and T1 which makes up the inferior trunk of the brachial plexus.

48
Q

Where does the ulnar nerve travel?

A

After leaving the brachial plexus, the ulnar nerve travels down the posterior compartment of the arm and through the cubital fossa. After passing through the cubital fossa, it travels anteriorly down the ulnar (medial) side of the forearm to pass under the flexor retinaculum and enter the hand.

49
Q

Describe the surfaces of the hand supplied by cutaneous branches of the ulnar nerve.

A

palmar and dorsal aspects
of the medial 1 ½ digits (digits 4 and 5) and adjacent palm

50
Q

Describe the normal anatomy of the ACL and PCL

A

These are deep ligaments of the knee and prevent the posterior (PCL) or anterior (ACL) dislocation of the tibia on the fixed femur.

51
Q

Describe the normal anatomy of the LCL and MCL

A

These ligaments stabilize the hinge motion of the knee and prevent excessive medial and lateral movement. The MCL joins the distal femur to the proximal tibia. The LCL joins the distal femur to the proximal fibula.

52
Q

Describe the normal anatomy of the medial meniscus and lateral meniscus

A

The menisci help to cushion the knee, acting as shock absorbers. They are c-shaped fibrocartilaginous pads on the condyles of the tibia.

53
Q

What mechanism is most likely to have caused the ‘unhappy triad’

A

The hard hit of the lateral side of the knee is the mechanism that has most likely caused this. This leads to a force pushing the knee medially, putting significant strain on the MCL, ACL, and medial meniscus.

54
Q

Which branch of the aorta supply the head.

A
  1. common carotid arteries
55
Q

Where do the left and right common carotid arteries arise from?

A

Left = arise directly from the aorta
Right = arise from the brachiocephalic trunk

56
Q

What do the common carotid arteries birfucate into to supply the head?

A

the internal and external carotid arteries.

57
Q

Which branch of the aorta supplies the upper limb

A

the subclavian arteries

58
Q

Describe the pathway of the subclavian arteries into the arm

A

they continue into the axilla where they become the axillary arteries and then into the arm as the brachial artery then into the forearm as the radial and ulnar arteries.

59
Q

describe the pathway of the abdominal aorta down to supply the lower limb

A

the abdominal aorta bifurcates into the left and right common iliac arteries and then further divide into the external and internal iliac arteries. The external iliac arteries continue to the lower limb where they become the femoral artery after passing through the femoral triangle. It then passes through the popliteal fossa and becomes the popliteal artery to supply the rest of the lower limb

60
Q

describe the pathway of the abdominal aorta down to supply the pelvis

A

the abdominal aorta bifurcates into the left and right common iliac arteries and then further divide into the external and internal iliac arteries. The internal iliac arteries then supply the pelvic and gluteal region, including the pelvic organs and muscles.
