Neuroanatomy Flashcards
Spinal Cord
Carries nerve impulses to (afferent) and from (efferent) the brain
Reticular Formation
Regulates level of consciousness
Medulla
Responsible for vital life functions (heart rate, breathing, etc)
Pons
Bridge between cerebral hemispheres and cerebellum
Midbrain
Important nuclei for movement, vision and hearing
Cerebellum
Motor modulation; learning of motor sequences
Hindbrain
Brainstem and Cerebellum
Brainstem
Reticular activating system
Diencephalon
Thalamus and hypothalamus
Thalamus
Group of numerous nuclei (e.g. visual, auditory, somatosensory); a major relay station for sensory info before projected to cortex
Hypothalamus
Responsible for internal milieu (temperature); fight, flight, food, and reproductive drives
Longitudinal Fissure
Separate hemipheres
Sylvian Fissure
Separates temporal from frontal and parietal; insular cortex is buried inside
Central Sulcus
Separates frontal form parietal
Parieto-Occipital Sulcus
Separates parietal from occipital
Basal Ganglia Function
Contributes to motor control and executive function
Basal Ganglia Parts
Caudate, Putamen, Globus Pallidus
Grey Matter Disruptions
Focal deficits
White Matter Disruptions
Disconnection sydromes
Association Pathway
Connect same side of brain
Projection Pathway
Connect cortical and subcortical areas of same side of brain
Commissural Pathway
Connect right and left hemispheres (corpus collosum)
Ventricles
Provide cushion during impact; drain waste products from brain
Meninges
Three membranes surrounding and protecting the brain and spinal cord; Dura-Arachnoid-Pia
