It is also referred to as “Ginglymus”.

Question 9

What type of Axis does a Hinge joint follow?

Answer 9

because of this hinge joints only allow for Flexion and Extension.

Question 10

What are some examples of Hinge joints?

Answer 10

Ex: Elbow, ankle and knee.

Question 11

What is a Pivot Joint?

Answer 11

The rounded or pointed portion of one bone articulates with a ring formed partly by another bone and partly by another ligament.

Question 12

What are some examples of Pivot joints?

Answer 12

Ex: Atlanto-axial joint and the Radioulnar joint.

Question 13

What are some examples of Pivot joints?

Answer 13

Ex: Atlanto-axial joint and the Radioulnar joint.

Question 14

What is a Condyloid Joint?

Answer 14

The Convex oval shaped projection of one bone fits into the oval shaped depression of another bone.

Question 15

What is another name for a Condyloid joint?

Answer 15

They are also referred to as “Ellipsoidal Joints”.

Question 16

What is another name for a Condyloid joint?

Answer 16

They are also referred to as “Ellipsoidal Joints”.

Question 17

What are some examples of a Condyloid Joint?

Answer 17

Ex: Radoiocarpal joint (Wrist Joint), Metacarpal phalagioal joints.

Question 18

What type of Axis does a Condyloid joint follow?

Answer 18

This type of joint is a “biaxial” joint so it permits movement around two axes.
The types of movements permitted are Flexion-extension and Aduction-Abduction. And limited Circumduction.

Question 19

What is a Saddle Joint?

Answer 19

The articular surface of one bone is saddle shaped and the articular surface of another bone fits into the saddle.

Question 20

Consist of the Ball-like surface of one bone fitting into a cuplike depression of another bone.

Question 23

What is another name for Ball and Socket Joints?

Answer 23

They are also referred to as “Spheroid Joint”.

Question 24

What axis does ball and socket joint follow?

Answer 24

It is a Triaxial joint and the movements are “Flexion-extension, Adduction-Abduction, Rotation.
