Study Notes
Brain Terminology
- "Caudal" refers to the direction "toward the tail."
- "Rostral" indicates a position "toward the nose" or "higher" in a vertical orientation.
- "Meninges" are the connective tissue membranes that envelop the brain and spinal cord.
Brain Structure
- The cerebral cortex is the outer gray matter layer of the cerebrum.
- The brain contains four ventricles, which are fluid-filled internal chambers.
- The blood-brain barrier is formed by tight junctions between capillary endothelial cells.
Brain Development
- The medulla oblongata arises from the myelencephalon.
- The pons develops from the metencephalon.
Midbrain and Visual Reflexes
- Structures in the midbrain that mediate visual reflexes include the superior colliculi.
Cerebral Anatomy
- The thalamus is known as the "gateway to the cerebral cortex."
- The corpus callosum is a large, C-shaped structure that contains most commissural tracts of the brain.
- The cerebellum has a structure called the vermis connecting its left and right hemispheres.
Cerebral Lobes and Functions
- Five cerebral lobes exist: frontal, parietal, occipital, temporal, and insula.
- The frontal lobe is crucial for voluntary motor function, motivation, memory, mood, and aggression.
- The parietal lobe processes input from general senses, taste, and some visual signals.
- The occipital lobe is the primary visual center of the brain, while the temporal lobe handles auditory signals.
Cognition and Special Senses
- Cognition encompasses various mental processes such as reasoning, memory, and judgment.
- Special senses include equilibrium, smell, taste, hearing, and vision.
Cranial Nerves Overview
- There are twelve pairs of cranial nerves that emerge from the base of the brain and innervate head and neck muscles.
- Cranial nerves are classified into sensory, motor, or mixed based on their function.
- Purely sensory cranial nerves include CN I (olfactory) and CN II (optic).
Classification of Cranial Nerves
- Some cranial nerves, such as VI (abducens), XII (hypoglossal), XI (accessory), III (oculomotor), and IV (trochlear), are primarily motor.
- The facial nerve (VII) and vagus nerve (X) are classified as mixed nerves.
- The vestibulocochlear nerve (VIII) is predominantly sensory, responsible for hearing and equilibrium.
Role of Specific Cranial Nerves
- The glossopharyngeal nerve (IX) transmits both sensory and motor impulses.
- The vagus nerve is vital for regulating cardiac, pulmonary, digestive, and urinary functions.
- The accessory nerve (XI) sends motor signals for neck and shoulder movements.
Important Brain Regions
- The prefrontal cortex is involved in decision-making regarding emotional expressions.
- The Wernicke area, found in the left hemisphere, interprets written and spoken language.
Connections Between Cerebral Hemispheres
- Hemispheric lateralization describes functional differences between the left and right cerebral hemispheres.
- Retrograde amnesia affects a person's ability to remember past events after a head injury.
