Final answer:
When the SBS deviates cephalic and decreases extension, it can lead to increased pressure on the pituitary gland and affect the flow of cerebrospinal fluid and blood to the brain, causing various symptoms.
Step-by-step explanation:
When the entire SBS (Sphenobasilar Synchondrosis) deviates cephalic (up) and decreases extension, it can lead to various consequences. One possible consequence is increased pressure on the pituitary gland, which can affect the release of hormones and disrupt the body's endocrine system. Additionally, this deviation can also affect the flow of cerebrospinal fluid and blood to the brain, potentially causing symptoms such as headaches, dizziness, and visual disturbances.
