Q

What is the orientation of the fibrous bands of the anterior ligament of the head of the fibula?

A

Obliquely upwards and medially from the front of the head of the fibula.

17
Q

What type of movement occurs at the superior/proximal tibiofibular joint?

A

A small amount of gliding movement.

18
Q

What is the nerve supply for the superior/proximal tibiofibular joint?

A

Common peroneal nerve.

19
Q

What is the role of the synovial membrane in the superior/proximal tibiofibular joint?

A

It lines the capsule and is attached to the margins of the articular surfaces.

20
Q

Fill in the blank: The superior/proximal tibiofibular joint is classified as a ______ joint.

A

[synovial plane/gliding]

21
Q

What ligaments are associated with the superior/proximal tibiofibular joint?

A

Anterior ligament, posterior ligament, and interosseous membrane.

22
Q

What type of joint is the inferior/distal tibiofibular joint?

A

A fibrous joint (syndesmosis)

It connects the fibula and tibia at their lower ends.

23
Q

What surfaces are involved in the inferior/distal tibiofibular joint?

A

Rough, triangular surface on the medial aspect of the fibula and the fibular notch on the tibia

These surfaces facilitate the connection between the two bones.

24
Q

What is the primary ligament uniting the fibula and tibia in the inferior/distal tibiofibular joint?

A

Interosseous ligament

This ligament is continuous with the interosseous membrane above.

25
Q

What are the additional ligaments supplementing the inferior/distal tibiofibular joint?

A

Anterior and posterior tibiofibular ligaments

These ligaments provide further stability to the joint.

26
Q

Which tibiofibular ligament is thicker and broader?

A

Posterior tibiofibular ligament

This ligament is located beneath the anterior tibiofibular ligament.

27
Q

Where do the anterior and posterior tibiofibular ligaments extend from and to?

A

From the borders of the fibular notch of the tibia to the anterior and posterior surfaces of the lateral malleolus of the fibula

These ligaments help maintain the stability of the joint.

28
Q

What is the function of the transverse tibiofibular ligament?

A

Attaches along the inferior border of the posterior surface of the tibia and upper part of the malleolar fossa of the fibula

This ligament is strong and thick, contributing to the joint’s stability.

29
Q

Fill in the blank: The inferior/distal tibiofibular joint is primarily connected by the _______.

A

interosseous ligament

This ligament is crucial for the integrity of the joint.

30
Q

True or False: The anterior tibiofibular ligament is thicker than the posterior tibiofibular ligament.

A

False

The posterior tibiofibular ligament is actually thicker and broader.
