PH 6C 76    Abducens Nucleus    
Nuclei in pons providing motor impulses that control eyeball movement via the abducens (VI cranial) nerves.

PH 6C 77    Arachnoid Villi / Granulations     
Small protrusions of the arachnoid (the thin second layer covering the brain) through the dura mater (the thick outer layer); allow cerebrospinal fluid to exit the sub-arachnoid space and enter the blood stream; act as one-way valves.

PH 6C 78    Calcarine Fissure / Calcarine Sulcus    
Located on the medial surface of the occipital lobe and divides the visual cortex into two. 

PH 6C 79    Central Sulcus    
A prominent landmark of the brain, separating the parietal lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex.

PH 6C 80    Cerebral Aqueduct    
Contains cerebrospinal fluid, and connects the third ventricle in the diencephalon to the fourth ventricle within the region of the mesencephalon and metencephalon.

PH 6C 81    Choroid Plexus    
A structure in the ventricles of the brain where cerebrospinal fluid is produced.

PH 6C 82    Diencephalon    
Located on top of the brain stem; consists of the thalamus, the subthalamus, the hypothalamus, and the epithalamus.

PH 6C 83    Facial Motor Nucleus / Facial Nucleus    
A collection of neurons in the brainstem that belong to the facial nerve (cranial nerve VII); they innervate the muscles of facial expression and the stapedius.

PH 6C 84    Fourth Ventricle    
Extends from the cerebral aqueduct to the obex, and is filled with cerebrospinal fluid.

PH 6C 85    Grey Matter / Gray Matter    
A major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrite, myelinated and unmyelinated axons), glial cells (astroglia and oligodendrocytes) and capillaries; includes regions of the brain involved in muscle control, and sensory perception such as seeing and hearing, memory, emotions, speech, decision making, and self-control.

PH 6C 86    Hypoglossal Nucleus    
In the medulla oblongata; the nucleus of origin of the hypoglossal nerve (the twelfth cranial nerve that innervates muscles of the tongue).

PH 6C 87    Lateral Sulcus / Sylvian Fissure / Lateral Fissure    
Divides both the frontal lobe and parietal lobe above from the temporal lobe below.
 
PH 6C 88    Lateral Ventricle    
The right and left lateral ventricles are structures within the brain that contain cerebrospinal fluid; part of the body's ventricular system, which acts as a continuation of the central canal of the spinal cord; contains cerebrospinal fluid.

PH 6C 89    Medial Lemniscus / Reil's Band / Reil's Ribbon    
An ascending spinal tract, carrying sensory information to the thalamus.

PH 6C 90    Medial Longitudinal Fasciculus    
A longitudinal bundle of fibres extending from the mesencephalon into the cervical segments of the spinal cord; involved in inervating the external eye muscles, and inervating the musculature of the neck.

PH 6C 91    Nucleus Ambiguus    
Contains the cells bodies of nerves that innervate the muscles of the soft palate, pharynx, and larnyx which are strongly associated with speech and swallowing.

PH 6C 92    Oculomotor Nucleus    
In the midbrain; the nerve controls most of the eye muscles.

PH 6C 93    Pia Mater    
The delicate innermost layer of the meninges, which encloses the cerebrospinal fluid and so helps to protect and cushion the brain; allows blood vessels to pass through and nourish the brain. The space created between blood vessels and pia mater functions as a lymphatic system for the brain. 

PH 6C 94    Pontine Tegmentum    
A part of the pons of the brain involved in the initiation of REM sleep.

PH 6C 95    Pretectal Nucleus    
Part of the subcortical visual system; involved primarily in mediating behavioural responses to acute changes in ambient light such as the pupillary light reflex, the optokinetic reflex, and temporary changes to the circadian rhythm.

PH 6C 96    Pyramidal Neuron, Hippocampus    
The primary excitation units of the prefrontal cortex and the corticospinal tract; also found in the cerebral cortex and the amygdala.

PH 6C 97    Subarachnoid Cavity / Subarachnoid Space    
The space between the arachnoid membrane and pia mater that is occupied by spongy tissue consisting of trabeculae (delicate connective tissue filaments) and intercommunicating channels in which the cerebrospinal fluid is contained.

PH 6C 98    Superior And Inferior Parietal Lobules    
The superior parietal lobule is involved with spatial orientation, receiving visual input as well as sensory input from the hands; also involved with other functions of the parietal lobe in general. Inferior parietal lobe involved in the perception of emotions in facial stimuli, and interpretation of sensory information.

PH 6C 99    Third Ventricle    
One of four connected cavities comprising the ventricular system within the human brain, containing cerebrospinal fluid.

PH 6C 100    Trochlear Nucleus    
Nuclei in midbrain provide motor impulses that control eyeball movement, via the trochlear nerves (IV cranial nerves).

PH 6C 101    White Matter / Arbor Vitae     
In the brain and superficial spinal cord, consisting mostly of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another and between the cerebrum and lower brain centres.
