CNS: Anatomy Physiology
Allows the brain to adapt and share duties
neuroplasticity
Gyrus houses Auditory Cortex and Wernickes (temporal)
Superior Temporal Gyrus
3 nerves that control eye movement
III Oculomotor
IV Trochlear
VI Abudcens
These neurons run from primary motor cortex
Upper Motor Neurons (UMNs)
4 CSF fluid filled cavities in brain
Ventricles
This sits at the base of the longitudinal fissure and how 2 hemispheres share sensory/motor info
Gyrus houses primary motor cortex
Precentral gyrus
2 nerves that originate in brainstem
I Olfactory
II Optic
These neurons sit in cranial nerve nuclei waiting to be activated
Lower Motor Neurons (LMNs)
3 Arteries that make up Internal Carotid system
Anterior, Middle, Posterior Artery
Parkinsons patients have involvement with this area of the brain
Basal Ganglia
Damage here could lead to executive dysfunction
Prefrontal Cortex/Frontal Lobe
Controls motor movement of tongue
XII Hypoglossal
Indirect pathway that sits in basal ganglia to help "fine tune" motor movement
Extrapyramidal system
Supplies blood to our face
External Carotid Artery
Damage here could bring "drunk" speech and wobbling uncoordinated gait
Cerebellum
Emotional center; fight or flight
Amygdala
Name 4 nerves that are both sensory and motor
V Trigeminal VII Facial
IX Glossopharyngeal X Vagus
This tract passes through pyramids of medulla down to the spinal cord to activiate LMNs in spinal nuclei
Corticospinal Tract
Loop of Arteries at the base of brain is the _______, which acts as a ________ for continuous blood flow
Circle of Willis; fail-safe
______ support and protect neurons
______ cells insulate axons with myelin
Glial cells; Schwann cells
Area helps me see in the dark to feel environment
Primary sensory cortex/Parietal Lobe
Nerves carry sensory info to _______ and carry motor info to _______
CNS (brain), PNS (muscles)
Motor neurons run on _______ pathways
Sensory neurons run on _______ pathways
Efferent; Afferent
__Stroke happens from occlusion blood vessel
__Stroke happens from burst of blood vessel
Ischemic; Hemorrhagic
