thick, outermost layer of the meninges surrounding and protecting the brain and spinal cord
which resembles a spider web, is the second layer of the meninges and is located between the dura mater and the pia mater
soft membrane, moderately tough that is the innermost meningal layer
a small protrusion or bump formed by the folding of the cerebral cortex
a groove in the brain matter, usually a groove found in the neocortex of the cerebellum
Central structures of the brain, including the midbrain, hindbrain, thalamus, and hypothalamus, responsible for most unconscious behavior
deep sulci i.e. longitudinal or lateral fissures, central sulcus
areas of the nervous system composed predominantly of cell bodies and blood vessels that function either to collect and modify information or to support that activity
CSF, Cerebrospinal Fluid
clear sodium chloride and other salts that fills the ventricles inside the brain and circulates around the brain and the spinal cord beneath the arachnoid later in the subarachnoid space.
Four cavities in the brain containing CSF and may help maintain metablism. Right lateral/left lateral; Third/Fourth;
nerve fibers with a fatty covering/ neural sheath.
carry out the brain's major functions
support cells aiding neuron function
group of cells forming a cluster ID'd with special stains to form a functional group
large collection of axons running together OUTSIDE the CNS
large collection of neurons running together INSIDE the CNS
Neocortex, basal ganglia, limbic system, olfactory bulb, lateral ventricles
Diencephalon, Mesencephalon, Metencephalon. (Midbrain, Hindbrain)
Myelencephalon, spinal cord
Fist Model of Brainstem
Fist - diencephalon
Wrist - midbrain
Evolutionarily oldest part of the brain: Pons, Medulla, reticular formation, cerebellum.
structures that coordinate and control most voluntary and involuntary movements, motor functions.
Midbrain/hindbrain area in which nuclei and fiber pathways are mixed, producing a netlike appearance; associated with sleep-wake behavior and behavioral arousal
central part of the brain that contains neural circuits for hearing and seeing as well as orienting movements
"roof", C for Chimney, area above the ventricle of the midbrain. Functions: sensory processing in visual and auditory stimuli, and production of orienting movements.
Floor, G for ground, area below the ventricle. a collection of nuclei with movement-related, species specific, and pain-perception functions.
Collis=hills, 4 little hills on the dorsal surface of the midbrain. superior: optic, inferior: auditory
"between brain" that integrates sensory and motor information on its way to the cerebral cortex
diencephalon structure containing many nuclei associated with temp reg, eating, drinking, and sexual behavior. Regulation of hormones. 3 F's fight, feed, fornicate.
Diencephalon structure that serves as the central switchboard, through which
largest region. neocortex, limbic system, basal ganglia. Newest part, coordinates advanced cognitive functioning
