Gross Anatomy

cerebrum, cerebellum, brainstem

2 hemispheres connected by corpus callosum. Organized into 4 lobes

balance, coordination, movement, motor skills, processing some types of memory

relay system for sensory info and controls life-sustaining function

connects brain and thalamus, 3 parts: substantia nigra, red nucleus, subthalamic nucleus

supplies dopamine to basal ganglia

oval mass of cells that acts as a relay station for sensorimotor info

supports motor movements

where some cranial nerves originate (parts of reticular formation)

contains some cranial nerve nuclei

telencephalon and diencephalon

cerebral cortex, basal ganglia, limbic system, lateral ventricles

thalamus, hypothalamus, 3rd ventricle

contributes to personality and mood, regulates cognitive functions, frontal lobe

primary motor strip, premotor cortex, supplemental motor area, frontal lobe

verbal expression and programming movements for speech production, frontal lobe

where motor activity and muscle control is initiated

helps acquire new motor sequences

plans and sequences motor actions

transverse temporal gyrus
