Where is gomphosis joint located?

a gomphosis is an example of a fibrous joint


What are the different joints in the body and what are their anatomical name and what movement do they allow and what are their functions?

list the various types of joints depending on their movement? There are 1. Gomphosis joints which are peg-in-socket fibrous joints. little movement. Example: attachment of tooth to bony socket. 2. Syndesmoses joints: two bones are bound by ligament only. Most moveable of fibrous joints. 3. Synchondroses joints: When bones are held together by hyaline cartilage. Example is rib being attached to sternum. 4. Ball and socket joints: Example would be head inside a cuplick depression. Head of femur into acetabulum of hip bone. 5. Hinge Joint: One bone that fits into a depression. Example: Finger and toe joints. 6. Saddle Joints: Each articular surface is shaped like a saddle. Example is trapeziometacarpal joint at the base of the thumb. 7. Symphyses: 2 bones joined by fibrocartilage. Pubic symphysis on pubic bone is an example. 8. Bony joints (Synostoses): 2 bones fused by osseous tissue: left and right mandible present at birth. 9. Synovial joints: Joint where two bones are separated by fluid filled space called a joint cavity. 10. Pivot joints: One bone has a projection that fits into a ringlike ligament of another. Examples are dens and axis. 11. Condyloid (ellipsoid) joints: oval convex surface on one bone fits into a similarly shaped depression on the next bone. 12. Gliding joints: Flat articular surface in which bones slide over each other.


Where is your pivot joint in your face located?

There is only one pivot joint in the body and it is located in the neck. It is the joint between the first and second cervical vertebrae also known as atlas and axis respectively. Axis has a the "peg" part of the pivot projecting upwards and atlas has the hole around it. This is the joint that allows the heart to rotate left to right.There are two pivot joints. One between C1 and C2 of the vertebrae. The second in the forearm between the ulna and radius.


What is the fullform of PEG?

The full form of PEG is "Polyethylene Glycol." It is a polymer compound commonly used in pharmaceuticals, cosmetics, and food products.


What vertebral column bears a peg-shaped dens that acts as a pivot?

The cervical vertebrae, specifically the second cervical vertebra (C2) known as the axis, bear a peg-shaped dens (odontoid process) that acts as a pivot for rotation of the atlas (C1) and allows for the turning of the head from side to side.
