The document provides an overview of the divisions and structures of the brain, including the forebrain (telencephalon and diencephalon), midbrain, and hindbrain (metencephalon and myelencephalon). Key structures discussed include the cerebral hemispheres, thalamus, hypothalamus, pons, cerebellum, and medulla oblongata. Common neurological conditions like headaches, stroke, and Horner's syndrome are also briefly mentioned.

19. TELENCEPHALON Cerebral Hemispheres Function : Determines Intelligence Personality Interpretation of Sensory Impulses Motor Function Planning and Organization Touch Sensation Location : The cerebrum is located in the anterior portion of the forebrain. It is divided into two hemispheres that are connected by the corpus callosum.

24. Thalamus

29. METENCEPHALON Pons Function: Arousal Assists in Controlling Autonomic Functions Relays Sensory Information Between the Cerebrum and Cerebellum Sleep Location: The pons is the portion of the brainstem that is between the midbrain and the medulla oblongata.

31. METENCEPHALON Cerebellum Function : Controls Fine Movement Coordination Balance and Equilibrium Muscle Tone Location : The cerebellum is located just above the brainstem, beneath the occipital lobes at the base of the skull.

33. MYELENCEPHALON Medulla Oblongata Function: Controls Autonomic Functions Relays Nerve Signals Between the Brain and Spinal Cord Location: The medulla oblongata is the lower portion of the brainstem. It is inferior to the pons and anterior to the cerebellum.

84. Epidural hematoma . Usually s/p head trauma . Brief +LOC, followed by lucid period. Then drowsy/coma/death . A well-defined biconvex collection of blood (arrows) compresses the left cerebral hemisphere. There is inward displacement of the grey-white junction (arrowheads) and slight rightward displacement of the left lateral ventricle.

87. Large acute subdural hemorrhage (arrows) revealed by CT scan at the level of the lateral ventricles. The hemorrhage has resulted in midline shift, with marked compression and displacement of the right ventricle (arrowheads). Because of the brain distortion and obstruction of CSF outflow, the left lateral ventricle is dilated (wavy arrows).

88. Right subdural hemorrhage revealed by MRI . The high intensity (white) hemorrhage has dissected under the temporal lobe, and the midline has been displaced to the left. Note the skull fracture overlying the hematoma.

89. Chronic bilateral subdural hematoma . This skull X-ray shows areas of calcification adjacent to the inner table of both parietal bones (arrows). The diagnosis was confirmed by CT.
