Match the brain areas with their primary functions:
Auditory area = Temporal lobe Primary sensory cortex = Parietal lobe Somatic motor cortex = Frontal lobe Motor speech area = Frontal lobe Premotor area = Frontal lobe Visual area = Occipital lobe Language/speech = Temporal lobe Taste (gustatory) area = Insula Seat of intelligence, abstract reasoning = Frontal lobe Major relay station for sensory information = Thalamus Associates experiences for abstract ideas, judgment, and conscience = Prefrontal area Axons form the major pyramidal tracts = Primary motor cortex Main visceral control center of the body = Hypothalamus Stage when vital signs reach their lowest normal levels = Stage 4 Indicated by movement of the eyes under the lids; dreaming occurs = REM Theta and delta waves begin to appear = Stage 3 Very easy to awaken; EEG shows alpha waves; may even deny being asleep = Stage 1 Typified by sleep spindles = Stage 2 Begins about 90 minutes after the onset of sleep = REM Necessary for emotional health; may be neural 'debugging' = REM Gateway to the cerebrum = Thalamus Motor command center = Cerebellum Survival center = Brain stem Executive suite = Cerebrum Visceral command center = Hypothalamus Where nerves serving the upper limbs = Cervical enlargement Anchors the spinal cord in place = Filum terminale Collection of nerve roots at the inferior end of the vertebral canal = Cauda equina Point of termination of the spinal cord in an adult = Conus medullaris

Study Notes
Nervous System Structures and Functions
- Auditory Area: Located in the temporal lobe, responsible for processing sound information.
- Primary Sensory Cortex: Found in the parietal lobe, it processes sensory inputs from the body.
- Somatic Motor Cortex: Located in the frontal lobe, it controls voluntary muscle movements.
- Motor Speech Area: Also situated in the frontal lobe, crucial for speech production.
- Premotor Area: Located in the frontal lobe, it is involved in planning and coordinating movements.
- Visual Area: Resides in the occipital lobe, specialized for processing visual stimuli.
- Language/Speech Processing: Occurs in the temporal lobe, important for understanding and producing language.
Specialized Regions of the Brain
- Taste (Gustatory) Area: Located in the insula, responsible for the sensation of taste.
- Thalamus: Functions as a major relay station for sensory information, containing specialized nuclei.
- Prefrontal Area: Involved in abstract reasoning, judgment, and conscience, helps associate experiences.
Motor Control and Coordination
- Primary Motor Cortex: Axons from this area form major pyramidal tracts, essential for motor function.
- Hypothalamus: Acts as the main visceral control center, regulating homeostasis.
- Cerebellum: Serves as the motor command center, coordinating balance and fine motor skills.
- Brain Stem: Functions as the survival center, controlling basic life functions.
Sleep Stages and Patterns
- Stage 1: Characterized by alpha waves, easily awakenable, may deny being asleep.
- Stage 2: Features sleep spindles, indicating a deeper sleep state.
- Stage 3: Theta and delta waves emerge, marking a significant phase of deep sleep.
- Stage 4: Vital signs reach their lowest normal levels, deep restorative sleep is achieved.
- REM Sleep: Eye movement occurs under the eyelids; associated with dreams and essential for emotional health.
Anatomy of the Spinal Cord
- Cervical Enlargement: Where nerves serving the upper limbs emerge.
- Filum Terminale: Anchors the spinal cord in place, providing support.
- Cauda Equina: A collection of nerve roots at the inferior end of the vertebral canal, responsible for lower limb innervation.
- Conus Medullaris: The termination point of the spinal cord in adults, ending at the lumbar region.
