Transcript text: All of the following joints are syndesmosis type joints, EXCEPT:
left forearm
left lower limb
right lower limb
sutures of the skull
right forearm
Solution
The answer is: sutures of the skull.
Explanation for each option:
Left forearm: The forearm contains the interosseous membrane between the radius and ulna, which is a syndesmosis joint. Therefore, this is a syndesmosis joint.
Left lower limb: The lower limb contains the interosseous membrane between the tibia and fibula, which is a syndesmosis joint. Therefore, this is a syndesmosis joint.
Right lower limb: Similar to the left lower limb, the right lower limb also contains the interosseous membrane between the tibia and fibula, which is a syndesmosis joint. Therefore, this is a syndesmosis joint.
Sutures of the skull: Sutures are fibrous joints found in the skull, but they are not syndesmosis joints. They are a different type of fibrous joint known as sutural joints. Therefore, this is not a syndesmosis joint.
Right forearm: Like the left forearm, the right forearm contains the interosseous membrane between the radius and ulna, which is a syndesmosis joint. Therefore, this is a syndesmosis joint.
In summary, the sutures of the skull are not syndesmosis joints, making them the exception in this list.
