Question

Name two cranial sutures and their locations.

Answer 1

Hint: The cranial sutures are fibrous bands of tissues that connect the various bones present in the skull. There are fourteen individual bones present in our skull that fuse to house the orbits of the eyes, nasal and oral cavities.

Complete answer:
Cranial sutures are bands of tissue that are fibrous in nature and their main function is to connect the bones of the skull. The name of two cranial sutures and their locations are as follows:
1)The squamous suture connects the temporal bone and the Parietal bone.
2)The sphenofrontal suture links the sphenoid bone and the frontal bone.

Additional Information:
-Sutures are present in our skull because it allows the bones to move during the birth process.
-They are an expandable joint so that the bone enlarges evenly as the brain grows and the skull expands. This results in the symmetrical development of the shape of the head.
-Some sutures extend to the four heads while others to the sides and back of the skull.
-One of the sutures in the middle of the skull extends from the front to the back.
-The four main sutures of the skull are the coronal, sagittal, lambdoid, and squamosal sutures.
-The sutures connect the frontal, parietal, temporal, and occipital bones.
-The coronal suture joins the frontal bone to the parietal bones, whereas the sagittal suture joins the two parietal bones to each other.
-The lambdoid suture marks the borders between the parietal bone and occipital bones.
-The sagittal and lambdoid sutures converge to form a lambda.
-The sphenoparietal suture articulates the sphenoid bone and the parietal bone, whereas the sphenofrontal suture links the sphenoid bone and the frontal bone.
-Nearby two years of age the skull bone of a child begins to join together because by the time the sutures become bone. When this occurs the suture is said to be closed.
-If any suture close to early use permanently this will hamper the growth of the brain in that area. This ultimately results in abnormal head shape.
