Tibia

Question 1

What is the difference between the ligaments and the meniscus?

Answer 1

The meniscus is a cartilage

Question 2

True or false?

The tibia also has a medial and lateral condyle that is connected, and is located at its distal end

Answer 2

False, it is separated by an intercondylar region at its proximal aspect

Question 3

What attaches to the intracondylar region?

Answer 3

The ACL, PCL, lateral, and medial menisci.

Question 4

What is located on the inferior of the condyles?

Answer 4

Roughening for muscles and ligaments and a tibial tuberosity.

Question 5

How many lateral menisci attachments are there?

Answer 5

Two.

Question 6

How many medial menisci attachment are there?

Answer 6

Two.

Question 7

How many ACL and PCL attachment sites are at the intracondylar region.

Answer 7

One each.

Question 8

True or false?

The lateral and medial condyle of tibia overhang the shaft!

Answer 8

True

Question 9

What are the two outgrowths of the medial and lateral tibial condyle?

Answer 9

Tubercle of intercondylar eminence.

Question 10

True or false?

The medial tibial condyle is larger than its lateral counterpart.

Answer 10

True, to accomodate the larger medial condyle of the femur.

Question 11

True or false?

The articular surface of both condyles are concave!

Answer 11

True

Question 12

What is the tibial plateau?

Answer 12

The superior surface of the tibia, the name “plateau” originates from its fluctuative nature.

Question 13

What does the nonarticular posterior medial surface of the tibia contain?

Answer 13

A horizontal groove that contains the semimembranous muscle.

Question 14

What structure does the underside of the lateral condyle contain?

Answer 14

An articular circular facet for articulation with the fibula.

Question 15

What is a big surface used for articulation of ligaments right below the condyle?

Answer 15

The tibial tuberosity.

Question 16

Is the tibial tuberosity anterior or posterior?

Answer 16

Anterior

To think about it, the palpability of the tibial tuberosity kinda gives it away that it is anterior.

Question 17

True or false?

The intercondylar eminence tubercle is the attachement of the patellar ligament!

Answer 17

False, it is the tibial tuberosity.

Question 18

What are the 3 surfaces of the tibia?

Answer 18

The posterior, medial, and lateral.

PML

Question 19

What are the 3 borders of tibia?

Answer 19

The anterior, interosseus, and medial border.

AIOM

Question 20

What are the characteristics of the medial surface of tibia?

Answer 20

It is large, smooth, and palpable with a ridge for the combined attachment of sartorius, gracilis, and and semintendinosus muscles

It is located between the anterior and median border

Question 21

What are the characteristics of the posterior surface?

Answer 21

Widest, contains the soleus line.

It is located between the medial and interosseus border.

Question 22

What is the characteristic of the lateral surface?

Answer 22

That it doesn’t have any characteristic besides being smooth.

The lateral surface is located between the interosseus border and the anterior border.

Question 23

Where does the anterior border descend from?

Look for anterior region structures!

Answer 23

The tibial tuberosity.

Question 24

Where does the medial border descend from?

Answer 24

The anterior end of the posterior groove of the medial tibial condyle.

Question 25

Where does the interosseus border descend from?

Answer 25

Anteroinferior of the circular facet of fibula

Interosseus means between bone, look for a border between the fibula and tibia.
