Study Notes
White Matter Tracts
- Projection fibers are composed primarily of axons that travel vertically or anterior-posterior in the brain.
- The interconnected deep brain structures form neural networks that are termed basal ganglia.
- Axons in the internal capsule travel laterally.
Brain Structures and Internal Anatomy
- Limbic System: Responsible for emotions, memories, and motivation.
- Lentiform nucleus: The globus pallidus is the outermost structure.
- White matter tracts: They are prominent examples of white matter tracts, acting as pathways for communication within the brain.
- Spinal cord: The sagittal view is used to visualize the body of the spinal cord.
- White matter tracts functions: They facilitate communication between different parts of the brain.
- Hypothalamus: Located in the diencephalon, below the thalamus.
- Brainstem: It connects the forebrain to the spinal cord.
- Brainstem nuclei: They control crucial functions like breathing, heart rate, and blood pressure.
- Cerebellum: Coordinates movement, balance, and posture.
- Brainstem damage: Can result in life-threatening issues due to its control of vital functions.
Meninges and Cerebrospinal Fluid
- Dura mater: The outermost layer of the meninges, providing protection and structural support.
- Mammillary bodies: They resemble breasts in the brain.
- Dura mater: Protects the brain and anchors it within the skull.
- Pia mater: The innermost layer of the meninges, tightly adhering to the brain's surface.
- Vomiting centre: Located in the medulla oblongata and triggers vomiting in response to various stimuli.
- Brainstem: Composed of the midbrain, pons, and medulla oblongata.
- Arachnoid mater: It is vascularized and separated from the pia mater by the subarachnoid space.
- Meninges and bone: Meninges are membranes that surround and protect the brain and spinal cord, located beneath the bone.
- Optic nerves: They converge to form optic tracts, carrying visual information to the brain.
- Cerebrospinal fluid: It cushions the brain and spinal cord, providing protection and nutrients.
- Pia mater: This layer closely adheres to the brain, following its contours.
Venous Sinuses and Ventricles
- Falx: Its name originates from its sickle shape in Latin.
- Superior sagittal sinus: Drains venous blood from the brain.
- Tentorium cerebelli: Separates the cerebellum from the cerebrum.
- Cavernous and petrosal sinuses: Located near the base of the skull.
- Valveless veins: Their absence allows for blood reflux into the cavernous sinus, potentially causing serious complications.
- Inferior sagittal sinus: Drains venous blood from the brain.
- Venous sinuses: They act as drainage routes for venous blood from the brain.
- Falx cerebelli: Separates the two hemispheres of the cerebellum.
- Ventricles: They produce and circulate cerebrospinal fluid, protecting the brain and transporting nutrients.
- Subdural hematoma: A medical term for a ruptured vein in the subdural space.
- Arachnoid granulations: The site where cerebrospinal fluid is reabsorbed into the systemic veins.
- Cerebral aqueduct: The narrow passage that connects the third and fourth ventricles.
- Ventricles: Cavities within the brain that produce cerebrospinal fluid.
- Skull trauma: Can result in different types of injuries, including fractures, hematomas, and brain damage.
- Choroid plexus: Located within the ventricles and produces cerebrospinal fluid.
- Subdural veins: Venous structures located in the subdural space.
- Arachnoid granulations: Projections of the arachnoid mater that facilitate cerebrospinal fluid absorption into the venous system.
- Fourth ventricle: Located in the brainstem, filled with cerebrospinal fluid.
