Term

Gyrus 

 

Sulcus

Definition
Hills and valleys create surface area necessary for the massive amount of cerebral cortex tissue within the cranial cavity
Term
White matter
Definition
Connect regions within the nervous system gets its color from myelin in the myelinated axons.

bundles of whatever matter called tracts
Term
Cerebral hemispheres
Definition
Each hemisphere receives and sends information to the opposite side of the body
Term
Gray matter
Definition
Location of neuron's cell bodies dendrites and unmyelinated axons houses motor neurons
Term
Longitudinal Fissure
Definition
Separates cerebral hemisphere
Term
Corpus collosum
Definition
Provides primary white matter communication link between cerebral hemispheres
Term
Frontal lobe
Definition
Anterior portion of the cerebral cortex. Primarily concerned with voluntary motor functions concentration verbal communication decision making planning and personality
Term
Precentral gyrus
Definition
Portion of the frontal lobe that houses the primary motor cortex where neurons control voluntary skeletal muscle activity
Term
Central sulcus
Definition
Boundary between frontal and pariatal lobes
Term
Pariatal lobe
Definition
Portion of the cerebral cortex involved with general sensory functions
Term
Postcentral gyrus
Definition
Portion of the pariah tolo that houses the primary somatosensory cortex,where neurons receives somatic sensory information from touch, pressure,pain,and temperature receptors
Term
parieto-occipital sulcus
Definition
Boundary between paridal lobes and occipital lobe
Term
Occipital lobe
Definition
Post your proportion of the cerebral cortex responsible for processing incoming visual information and storing visual memories
Term
Lateral sulcus
Definition
Boundary between frontal and parietal lobes and temporal lobes
Term
insula
Definition
Portion of the cerebral cortex deep to the lateral sulcus allows us to taste food
Term
Temporal lobe
Definition
Lateral portion of the cerebral cortex involved with hearing and smell
Term
fornix
Definition
Thin tract of white matter involved in limbic system functions
Term
septum pellucidum
Definition
Thin portion that separates the lateral ventricles
Term
cerebral nuclei
Definition
Deep bodies of Gray matter within the cerebral often paired. Helps with coordinated muscle movement
Term
Lateral ventricles
Definition
Spaces within the cerebral hemispheres that produce and circulate cerebrospinal fluid
