Chapter 7 Flashcards
The skeleton consists of… (4)
bones, cartilage, joints (or articulations) and ligaments
Which suture occurs where each parietal bone meets a temporal bone inferiorly, on each lateral aspect of the skull?
Squamous suture
This suture, running in the coronal plane, occurs anteriorly where the parietal bones meet the frontal bone
coronal suture
Number 2,
This suture occurs where the right and left parietal bones meet superiorly in the midline of the cranium
Sagittal suture
This suture occurs where the parietal bones meet the occipital bone posteriorly. This suture is so named because it resembles the Greek letter lambda
lambdoid suture
