INFERIOR OLIVARY COMPLEX This is the largest nuclear group in the brain stem. It consists of a convoluted band of cells that lie dorsal to the pyramid. This nucleus is by far the most characteristic and striking feature of the medulla. Sadly, we know little about inferior olivary function(s), but its very intimate association with the cerebellum suggests it is involved in motor coordination and most likely motor “learning”.

More on the Circle of Willis. Been studying it today.

The falx cerebri, also known as the cerebral falx, so named from its sickle-like form, is a strong, arched fold of dura mater that descends vertically in the longitudinal fissure between the cerebral hemispheres.

It is narrow in front, where it is attached to the crista galli of the ethmoid; and broad behind, where it is connected with the upper surface of the tentorium cerebelli.

Its upper margin is convex, and attached to the inner surface of the skull in the middle line, as far back as the internal occipital protuberance; it contains the superior sagittal sinus. Its lower margin is free and concave, and contains the inferior sagittal sinus.

The falx cerebri is known to calcify with age.

Cervical Subarachnoid Catheter Placement for Continuous Cerebrospinal Fluid Drainage: A Safe and Efficacious Alternative to the Classic Lumbar Cistern Drain

Cerebrospinal fluid (CSF) drainage serves an important role in the management of patients with established or potential CSF fistulae. Classically, a lumbar CSF drain has been used for this purpose and has been shown to be safe and effective. In certain cases, such as extensive previous lumbar surgery, a lumbar drain cannot be used. In such instances, a cervical CSF drain can be inserted via a lateral C1-2 puncture and provides an excellent and safe alternative.
