Midbrain Pons Medulla
28
What makes up the midbrain?
Cranial nerves 1-4 | Relay station for vision, motor control (substantia nigra)
29
What is another name for midbrain?
Mesencephalon
30
What are the first four cranial nerves?
Olfactory-smell Optic-sight Occulomotor-movement of eyes Trochlear- movement of eyes
31
What makes up the pons?
Cranial nerves 5-8 | Relay station for vision, motor control
32
What are cranial nerves 5-8?
Trigeminal-chewing Abducens-abducts eyes/moves the eyes out Facial-provides movement and sensation to the face Acoustic- hearing
33
What makes up the medulla?
Cranial nerves 9-12 | Heart rate, breathing, blood pressure
34
What are cranial nerves 9-12?
Glossopharyngeal-swallowing and tongue epiglottis Vagus-autonomic nervous system Accessory- sternocleidomastoid Hypoglossal-helps with swallowing
35
What is the Latin definition of cerebellum?
Little brain
36
What makes up the cerebellum?
Spinocerebellum Cerebrocerebellum Vestibulocerebellum
37
What does the spinocerebellum do?
Coordinates muscle movement
38
What does the cerebrocerebellum do?
Coordinates motor planning
39
What does the vestibulocerebellum do?
Coordinates head and eye movement
40
If a stroke occurs in the cerebellum what is expected of the patient?
Ataxic movements
41
What makes up the spinal cord?
Dorsal column Spinothalamic tract Spinocerebellar tract Corticospinal tract
42
What does the dorsal column-medial lemniscal system do?
Fine touch, conscious proprioception and light touch
43
What does the spinothalamic tract do?
Pain and temperature
44
What does the spinocerebellar tract do?
Unconscious proprioception
45
What does the corticospinal tract do?
Motor movements
46
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.
47
What does the diencephalon do?
Coordinates how things move back and forth from conscious to unconscious thought.
48
What does the thalamus do?
Consciousness, alertness, sleep
49
What does the hypothalamus do?
Temperature, hunger, thirst, circadian rhythm (ability to know night and day and when to become sleepy)
50
What makes up the forebrain?
Cerebrum Thalamus Hypothalamus
51
What makes up the hindbrain?
Pons Medulla oblongata Cerebellum
52
What does the basal ganglia do?
Surrounds thalamus and initiates movement
53
What makes up the motor planning and programming of the basal ganglia?
Caudate nucleus and putamen (striatum) Globes pallidus Subthalamic Substantia nigra
54
What does the somatic nervous system do?
Afferent and efferent volitional activities (sensation in and motor output)
55
Is the autonomic nervous system conscious or subconscious?
Subconscious
56
What is the sympathetic system?
Fight or flight response
57
What is the parasympathetic system?
Body homeostasis or feed and breed Temperature regulation Adjusting to the environment
