cerebral cortex areas - Primary Motor Cortex
- function
- location
Function: Initiates VOLUNTARY SKELETAL muscle movements
Location: Frontal Lobe (precentral gyrus)
cerebral cortex areas - Premotor cortex
- function
- location
Function: controls COMPLEX MOTOR activities
Location: Frontal Lobe
cerebral cortex areas - Frontal Eye Field
- function
- location
Function: controls VOLUNTARY EYE movements
Location: Frontal Lobe
cerebral cortex areas - Broca’s area
- function
- location
Function: controls muscles involved in PRODUCTION of SPEECH
Location: Frontal Lobe (dominant hemisphere)
cerebral cortex areas - Wernicke’s Area
- function
- location
Function: COMPREHENDS WRITTEN + SPOKEN language
Location: Temporal Lobe (dominant hemisphere)
Cerebral Cortex Areas - Prefrontal Cortex
- function
- location
Function: intelligence, personality, behavior
Location: frontal lobe
Cerebellum - Function
- smooth coordinated movements
- maintains posture + balance
Thalamus - Function
- relay station for incoming SENSORY input
and
- MOTOR info from CEREBELLUM + BASAL NUCLEI
Hypothalamus - Function
- regulates: body temp, food intake, thirst intake, sleep/wake cycle, emotional responses
- controls AUTONOMIC responses
- produces hormones
Limbic System - Function
- establishes emotional states
- controls emotional responses
- formation of long term memories
Midbrain (mesencephalon) - Function
- mediates visual + auditory reflexes
- produces DOPAMINE
- relays MOTOR + SENSORY info b/w different parts of CNS
Pons - Function
- controls RESPIRATION
- relays MOTOR + SENSORY info b/w different parts of CNS
Medulla Oblongata - Function
Controls:
- HEART RATE + force of contraction
- RESPIRATION
- BLOOD vessel diameter
- relays MOTOR + SENSORY info b/w different parts of CNS
Reticular Formation - Function
- filters REPETITIVE SENSORY input
- maintains CORTICAL ALERTNESS + CONSCIOS (RAS)
