Increased head circumference. Increased head circumference is when the measured distance around the widest part of the skull is larger than expected for the child's age and background. A newborn's head is usually about 2 cm (centimeters) larger than the chest size. Between 6 months and 2 years, both measurements are about equal. After 2 years, the chest size becomes larger than the head.
Joints allow motion (articulation). The joints in the spine are commonly called Facet Joints. Other names for these joints are Zygapophyseal or Apophyseal Joints. Each vertebra has two sets of facet joints. One pair faces upward (superior articular facet) and one downward (inferior articular facet).There is one joint on each side (right and left).he joints in the spine are commonly called Facet Joints. Other names for these joints are Zygapophyseal or Apophyseal Joints. Each vertebra has two sets of facet joints. One pair faces upward (superior articular facet) and one downward (inferior articular facet).
Back pain diagnosis often includes the name of the part of the spine that is involved in causing the pain. Learn about the parts of the spine. The spine is made of 24 individual vertebrae, that go from the skull to the sacrum. The sacrum bone - which is really 5 bones that begin to fuse at about age one, with the fusion complete approximately by age 30 - plus the coccyx complete the spine at the bottom. (The coccyx is your tailbone, and is the very last bone of the spine.) The spine connects to the ribs and pelvis to make the trunk or core.
