Structure of the Nervous System: Functional Anatomy (Cerebral Cortex) 1
, The functions happen within 100 billion neurons and 10 trillion neuroglia
We have the biggest brain and supposedly correlates to intelligence. Both
the cerebral cortex and the frontal lobes experience expansion which
carries out functions including self control, planning and thoughts
Cerebral Cortex
Receives sensory info
Messages are sent for skeletal muscle movement
Integration of incoming and outgoing nerve impulses
Performs activities like thinking, learning and remembering
Basal Ganglia
Assists co-ordination of slow, sustained movements
Suppresses useless patterns of movement
Thalamus
Relays most sensory info from spinal cord and parts of the brain to
cerebral cortex
Interprets some sensory messages including pain, temp and pressure
Hypothalamus
Controls different homeostatic functions like body temp and respiration
Directs hormone secretion of pituitary
Cerebellum
Coordination of subconscious movements
