Study Notes
Cranial Nerves
- Twelve pairs of cranial nerves
- Sensory functions: Olfactory (I), Optic (II), Vestibulocochlear (VIII)
- Motor functions: Oculomotor (III), Trochlear (IV), Abducens (VI), Accessory (XI), Hypoglossal (XII)
- Mixed functions: Trigeminal (V), Facial (VII), Glossopharyngeal (IX), Vagus (X)
Limbic System
- Involved in emotional regulation, memory formation, and motivation
- Integrates emotional responses with physiological functions
Reticular Formation
- Network of neurons in the brainstem
- Regulates arousal, sleep-wake cycles, and attention
Reticular Activating System (RAS)
- Part of the reticular formation
- Maintains alertness and consciousness; filters sensory information and prioritizes stimuli
Primary Somatosensory Cortex
- Processes tactile information (postcentral gyrus)
Somatosensory Association Area
- Integrates sensory information for perception
Primary Visual Cortex
- Processes visual stimuli
Visual Association Area
- Interprets and integrates visual information
Cranial Nerve Functions & Locations
- Olfactory (I): Smell; located in the olfactory bulb
- Optic (II): Vision; originates in the retina
- Oculomotor (III): Eye movement; arises from the midbrain
- Trochlear (IV): Eye movement; arises from the midbrain
- Trigeminal (V): Facial sensation and mastication; located in the pons
- Abducens (VI): Eye movement; arises from the pons
- Facial (VII): Facial movement and taste; located in the pons
- Vestibulocochlear (VIII): Hearing and balance; located in the pons/medulla
- Glossopharyngeal (IX): Taste and swallowing; arises from the medulla
- Vagus (X): Autonomic functions; arises from the medulla
- Accessory (XI): Neck and shoulder movement; arises from the spinal cord
- Hypoglossal (XII): Tongue movement; arises from the medulla
