Answer: Outermost layer, tough and inelastic. โ Meninges: Arachnoid Mater (F) External View. Answer: Middle layer, just beneath the Dura Mater. โ Meninges: Pia Mater (F) External View. Answer: Innermost layer/separated from Arachnoid layer by CSF-filled subarachnoid space. โ Cerebrospinal Fluid (F) External View. Answer: Bathes and cushions CNS/ nourishes and removes waste from CNS. โ Cerebellum (S+F) External View. Answer: involved in fine motor control & coordination. โ Cerebellum: Cerebellar Vermis (S+F) External View. Answer: Important for movement and coordination.
โ Medial Longitudinal Fissure (S) External View. Answer: โ Gyri and Sulci (S) External View. Answer: โ Grey matter (S) External View.

Answer: โ Sylvian Fissure (S) External View. Answer: โ Pyriform Lobe (S+F) External View. Answer: Continuous with the olfactory bulbs and functions in smelling. (Labeled K in picture)
โ Optic Chiasm (S) External View. Answer: โ Pyramidal Tract (S) External View. Answer: โ I. Olfactory bulbs (Sensory) (S+F) Cranial Nerves. Answer: Sensation of smell Processing information about odor. โ II. Optic Nerve (Sensory) (S+F) Cranial Nerves. Answer: Sensation of vision โ III. Oculomotor Nerve (Motor) (S+F) Cranial Nerves. Answer: Movements of the eye and eyelid Parasympathetic control of pupil size โ IV. Trochlear Nerve (Motor) (S+F) Cranial Nerves. Answer: Controlling the extraocular muscles. (Same as the oculomotor and abducens) โ V. Trigeminal Nerve (Mixed) (S+F) Cranial Nerves. Answer: Sensation of touch to the face
- Sensation of pain associated with viscera

Medial View. Answer: Auditory and visual processing. โ Pons (S+F) Medial VIew. Answer: control of breathing movements/regulates states of attentiveness and arousal. โ Medulla (S+F) Medial View. Answer: decussation of fibers/regulation of autonomic functions (adjusts heart rate, blood pressure, respiration). (Located under the cerebellum between the pons and spinal cord) โ Brain Ventricles (F) Medial View. Answer: a series of cavities in the CNS that contain the cerebral spinal fluid. *Know where CSF is produced (Choroid Plexus) and the flow from one ventricle to the next (lateral->third->cerebral aquaduct->fourth). โ Brain Ventricles: Lateral (S) Medial View. Answer: โ Brain Ventricles: Third (S) Medial View. Answer: โ Brain Ventricles: Cerebral Aquaduct (S+F)
