Neuroanatomy Flashcards
Splits brain into right and left halves
Migsaggital
Divides brain into dorsal and ventral parts
Horizontal
Divides brain into anterior and posterior parts
Coronal
Parts of the brain
Cerebrum, Cerebellum, and Brain Stem
Cerebellum
Motor coordination
Brain Stem
Midbrain, pons, and medulla oblongatta
Brain Stem function
breathing, body temperature, heart rate, and blood pressure, etc
Frontal lobe
Planning, memory, and emotions
Parietal lobe
Integrate sensory information
Occipital lobe
Vision
Temporal lobe
Hearing
Frontal lobe has this cortex…
Primary motor cortex
Parietal lobe has this cortex…
Primary somatosensory cortex
Motor map
Topographic representation of the body found on the precentral gyrus of the frontal lobe
Senesory map
Topographic representation of the body found on the postcentral gyrus of the parietal lobe
Gray matter
Contains the cell bodies and dendrites of neurons, recieves information and regulates outgoing information
White matter
Contains the axons of neurons, transmits signals to other regions of the brain, spinal cord, and body
Thalamus
“Grand Central Station” of the brain. Most sensory information passes through the thalamus en route to the brain.
The Basal Ganglia
Striatum, Globus Pallidus, Substantia Nigra, and Subthalamic Nucleus
Basal Ganglia role
Regulates voluntary movement, cognition, and emotions
Striatum
Caudete Nucleus and Putamen
Globus Pallidus
Internal and external
Meninges
Dura, Subdural space, Arachnoid, Subarachnoid space, Pia
What fills the Subarachnoid space
Cerebrospinal fluid
Cerebrospinal fluid
Salty clear liquid
Ventricles
Interconnected cavities that are filled with CSF within the brain
Choroid Plexus
Specialized tissue within the ventricles that secretes CSF
