Brain and cranial nerves and Spinal cord and Spinal Nerves
- 1. Brain and Cranial Nerves
- 2. Cerebral Hemisphere • Gyri – a ridge on the cerebral cortex, generally surrounded by two sulci • Sulci – depressions or furrows • Longitudinal Fissure • Central Sulcus • Precentral gyrus, Postcentral Gyrus • Cerebral cortex – Lobes • Fontal, Parietal, Temporal and Occipital
- 8. • Cerebral Hemispheres • Corpus Callosum • Diencephalon • Brainstem • Cerebellum
- 13. Diencephalon and Cerebellum • Thalmus – Olfactory bulbs and tracts – Optic chiasma (optic nerves and tract) – Mammillary bodies • Hypothalamus – Pituitary gland – Infundibulum • Epithalamus – pineal gland (body) • Cerebellum – arbor vitae
- 26. Brainstem • Midbrain – Cerebral peduncles – Cerebral aquaduct – Corpora quadrigemina • Superior colliculi • Inferior colliculi • Pons • Medulla oblongata
- 33. Meninges • Dura mater – Periosteal layer – Meningeal layer • Dural sinuses – Subdural space • Arachnoid mater – Arachnoid villi – Subarachnoid space • Pia mater
- 35. CSF and Ventricles • Cerebral Spinal Fluid • Lateral Ventricles – Choroid plexuses • Third Ventricle – Cerebral aqueduct • Fourth Ventricle – Central canal of spinal cord – Subarachnoid space
- 40. Choroid Plexus
- 41. Choroid Plexus
- 42. Cranial Nerves • Olfactory (I) • Optic Nerve (II) • Vestibulocochlear Nerve (VII) • Vagus Nerve (X)
- 50. Spinal Cord and Spinal Meninges • Spinal Cord – Conus medullaries – Cauda equine – Filum terminale – Denticulate ligaments • Spinal Meninges – Epidural Space – Dura Mater – Arachnoid mater • Subarachnoid Space – Pia Mater
- 55. Spinal Cord (cross-section) • White Matter – Anterior median fissure – Posterior median fissure • Gray Matter – Dorsal horn – Ventral horn – Lateral horn – Gray commissure • Central canal • Dorsal Root (sensory) – Dorsal root ganglion • Ventral Root (motor)
- 60. Spinal Nerves • Dorsal rami • Ventral Rami
- 63. Nerve Plexuses • Cervical plexus ( C1 – C5) • Brachial plexus (C5 – T1) • Lumbar plexus (L1 – L4) • Sacral plexus (L4 – S4)
- 64. Nerve Plexuses • Cervical plexus ( C1 – C5) • Brachial plexus (C5 – T1) • Lumbar plexus (L1 – L4) • Sacral plexus (L4 – S4)
