Which bone (yellow) is centrally located and joins with most of the other bones of the skull?
-
The yellow bone shown in the video is called the sphenoid bone. This lies at the center of the base of the skull and it holds all the other cranial bones together.
What are the two mechanisms by which the bones of the body are formed and which bones are formed by each mechanism?
-
There are two types of bone ossification that occur in the body, intramembranous and endochondral. Intramembranous ossification occurs on or within fibrous connective tissue membranes. This occurs in many bones of the skull and clavicles. On the other hand, endochondral ossification is the replacement of cartilage by bone. This process occurs in most of the rest of the skeleton.
What are the synovial joints being described in the video?
-
The synovial joints that were described in the video were:
-
ball-and-socket joint (hips and shoulders)
-
hinge joint (knees and elbows)
-
pivot joint (neck)
-
condyloid joint (found in the wrist)
-
saddle joint (fingers)
-
gliding joint (vertebrae)
-
Which type of synovial joint allows for the widest ranges of motion?
-
Because of the hemispherical head that fits within a cuplike depression, the ball and socket joint allows for the widest range of motion.
