Final answer:
Pressure points in the head and neck areas refer to regions critical for the support and functioning of the head, including cerebrospinal fluid pressure, muscular tension for posture and movement, and vascular pressure for brain blood supply.
Step-by-step explanation:
The pressure points on the head and neck areas are not only crucial for supporting the structure and movement of the head but also for the circulation of cerebrospinal fluid and blood, which are vital for brain function. The musculature of these regions is responsible for holding the head erect and allowing for movement, while the vascular system transports oxygen-rich blood to the brain.
Pressure points on the head and neck include areas linked to the cerebrospinal fluid pressure and muscular tension, as well as vascular pressure critical for brain function. Cerebrospinal fluid (CSF) pressure is typically between 5 to 12 mm Hg, providing flotation to the brain. This buoyancy effect helps to offset the brain's weight, protecting it from resting against the skull which can lead to headaches and damage.
