In the cerebrum, what is the grey matter?
In the cerebrum, what is the white matter?
Axons that send signals thought the body.

Dents of brain or bumps
What is sulcus?
The depth of the grooves
What is the main part of the brain?

What does the frontal lobe control
The frontal lobe is made up of what four areas?
Primary motor cortex
Pre-frontal association cortex
What does the pre-motor cortex do?
What does the primary motor cortex do?
Volitional movement (through middle of the brain)
What does the pre-frontal association cortex do?
Thought, cognition, emotion, decision making, problem solving
What does Broca's area do?
What makes up the parietal lobe?
The primary somatosensory cortex
What does the primary somatosensory cortex do?
Visual spatial awareness
What makes up the occipital lobe?
The primary visual cortex
Visual association cortex
What does the primary visual cortex do?
What does the visual association cortex do?
Higher order visual processing
What makes up the temporal lobe?
Primary auditory cortex
What does the primary auditory cortex do?
What does the Wernicke's area do?
What does the hippocampus do?
What makes up the brain stem?
What makes up the midbrain?
Cranial nerves 1-4
Relay station for vision, motor control (substantia nigra)
What is another name for midbrain?
What are the first four cranial nerves?
Occulomotor-movement of eyes
Trochlear- movement of eyes
What makes up the pons?
Cranial nerves 5-8
Relay station for vision, motor control
What are cranial nerves 5-8?
Abducens-abducts eyes/moves the eyes out
Facial-provides movement and sensation to the face
What makes up the medulla?
Cranial nerves 9-12
Heart rate, breathing, blood pressure
What are cranial nerves 9-12?
Glossopharyngeal-swallowing and tongue epiglottis
Vagus-autonomic nervous system
Hypoglossal-helps with swallowing
What is the Latin definition of cerebellum?
What makes up the cerebellum?
What does the spinocerebellum do?
Coordinates muscle movement
What does the cerebrocerebellum do?
Coordinates motor planning
What does the vestibulocerebellum do?
Coordinates head and eye movement
If a stroke occurs in the cerebellum what is expected of the patient?
What makes up the spinal cord?
What does the dorsal column-medial lemniscal system do?
Fine touch, conscious proprioception and light touch
What does the spinothalamic tract do?
Pain and temperature
What does the spinocerebellar tract do?
What does the corticospinal tract do?
What is the monosynaptic stretch reflex?
When the muscle is stretched the body reacts by firing the muscles to protect itself. It also deals with removing your hand from a hot surface.
What does the diencephalon do?
Coordinates how things move back and forth from conscious to unconscious thought.
What does the thalamus do?
Consciousness, alertness, sleep
What does the hypothalamus do?
Temperature, hunger, thirst, circadian rhythm (ability to know night and day and when to become sleepy)
What makes up the forebrain?
What makes up the hindbrain?
What does the basal ganglia do?
Surrounds thalamus and initiates movement
What makes up the motor planning and programming of the basal ganglia?
Caudate nucleus and putamen (striatum)
What does the somatic nervous system do?
Afferent and efferent volitional activities (sensation in and motor output)
Is the autonomic nervous system conscious or subconscious?
What is the sympathetic system?
Fight or flight response
