Axial (plan)
How is the CNS divided?
Cerebral hemispheres
Structure beneath the hemispheres
Brainstem
Cerebellum
Spinal cord
How is the brain protected?
Cranial cavity lined with dura mater
What are the 4 lobes of each hemisphere?
Frontal, temporal, parietal and occipital
The frontal lobe
Completes higher mental functions (planning and language) and is the site of the primary motor complex
The parietal lobe
Site for incoming sensations from the body
The temporal lobe
Processes sound and is involved in memory and vision
The occipital lobe
Principle area for vision and processes emotions
What is in the core structure?
Basal ganglia, thalamus, hypothalamus
Basal ganglia
Controls movement
Thalamus
Initial processing of sensory information
Hypothalamus
Important for homeostasis and endocrine regulation
The brainstem
Important for movement, posture and autonomic function
Cerebellum
Controls posture and movement
Spinal cord
Controls and processes sensory inputs and motor outputs
