-
sesamoid bones
C
Correct answer
Explanation
These bones ossify partly from cartilage and partly from mesenchymal concentrations. The most prominent examples are clavicle, mandible, occipital, temporal and sphenoid, etc.

Correct answer
Explanation
An adult human body has 206 bones. An infant may have from 300-350 bones at birth. Many of these fuse together as the infant grows. When some bones fuse and become one bone (most obvious examples are in the skull, sacrum and hip bones) the number of overall bones drops to the 206 bones that most adults have.

-
Fibrous joint : Between phalanges
-
Cartilaginous joint : Skull bones
-
Gliding joint : Between zyga pophyses of the successive vertebrae
-
Hinge joint : Between vertebrae
C
Correct answer
Explanation
Gliding joint is a type of joint allows for gliding movements between flat surfaces as the surfaces slide over one another. Only a limited amount of movement is allowed such as those between the articular processes (zygapophyses) of successive vertebrae.
Fibrous joint is present between skull bones. Cartilaginous joint is present between vertebrae. Hinge joint is present between knee and elbow.
