Central Nervous System (Cerebrum (Lobes (Frontal (Responsible for planning…

- - - - Responsible for planning, thinking, decision making, memory, producing voluntary movement
    - - Responsible for sensory awareness of stimuli, somatic sensation, sounds, objects, and body location
    - - Primary auditory/olfactory cortices. Recognize objects, words, faces. Responsible for language comprehension, emotional response, and memory.
    - - Visual cortex for visual stimuli
    - - Visceral sensory cortex for gustation and general visceral sensation (especially pain)
  - - - Primary somatosensory cortex (for skin, muscles, joints, etc.)
    - - Location of primary motor cortex. Neurons called pyramidal neurons that synapse to motor neurons for voluntary movement.
  - - - Connect parts of same hemisphere in cortex
    - - Run vertically with ascending or sensory/afferent and descending or motor/efferent axons/fibers
    - - Transfer information from one hemisphere to other mostly through the corpus callosum
- - - - Connect cerebrum to cerebellum through the pons
    - - Connect medulla oblongata to cerebellum (this is an afferent connection originating in the spinal cord)
    - - Connect midbrain to cerebellum
- - - - Tough, fibrous connective tissue (with periosteal layer, meningeal layer, subdural space in brain)
    - - Subarachnoid space and blood vessels beneath it with cerebrospinal fluid
    - - Very thin, vascular layer on surfaces of cerebrum/cerebellum (with capillaries)
