Study Notes
Cerebellum
- Consists of a cortex of grey matter, with an internal core of branching central medulla, also known as white matter.
Brain Stem and Spinal Cord
- Characterized externally by white matter.
- Grey matter forms one or more masses within the white matter.
Mid-brain
- The substantial nigra is a large mass of grey matter extending throughout the mid-brain.
- The neurons of nigra contain numerous melanin pigments in their cytoplasm.
Pons
- Consists of two parts: a small dorsal region and a bulky ventral region.
- The bulky ventral region is also known as basal pons, within which the neuron cell bodies are known as pontine region.
Medulla Oblongata
- In the upper part of the medulla oblongata, the 4th ventricle narrows.
- It forms a central canal which continues down the spinal cord.
- The central canal is surrounded by central grey matter.
- The inferior olivery complex is the most obvious feature of the upper half of the medulla oblongata.
- Neurons relay central and spinal efferent stimuli to the cerebral cortex.
Ventricles of the Brain
- The interior of the brain consists of cavities known as ventricles.
- The choroid plexus is a mass of capillaries invested by epidermal cells.
- The choroid plexus arises from the wall of each ventricle and projects into the ventricular cavity.
- Ventricular epidermal cells are responsible for the production of about 50%-70% of cerebrospinal fluid.
- The rest of the cerebrospinal fluid is produced by the ultrafiltration of blood plasma by the choroidal capillaries.
