Frontal sinus. The frontal sinuses are pockets of space located above the orbit of each eye in the frontal bone. They are lined with mucus membrane, which secretes fluid that moistens and protects the areas it covers. The size and shape of the frontal sinus can vary from person to person.These spaces fill up with mucus, which then drain into the nose. The draining process can be hindered by blockages. If mucus accumulates, this can cause infections.hey are lined with mucus membrane, which secretes fluid that moistens and protects the areas it covers.

The frontal lobes play a major role in the planning and execution of movements. In the frontal lobe, there are four important gyri. Roughly parallel and anterior to the central sulcus is the Precentral Gyrus (also called the motor strip).The precentral gyrus represents the primary motor cortex. This motor cortical area contains motor neurons whose axons extend to the spinal cord and brain stem and synapse on motor neurons in the spinal cord.he precentral gyrus represents the primary motor cortex.
