Central Nervous System

The central nervous system consists of the ___ and ___ brain, spinal cord
5 Lobes of the Cerebral Hemispheres 1) Frontal 2) Parietal 3) Temporal 4) Occipital 5) Insula
The 4 Motor Areas 1) Precentral Gyrus 2) Premotor Cortex 3) Frontal Eye Field 4) Broca's Area
Three Parts of Diencephalon Thalamus, Hypothalamus, Epithalamus
3 Parts of Brain Stem, superior to inferior 1) Midbrain, Pons, Medulla Oblongata
8 Sensory Areas of the Cerebral Cortex 1) Primary somatosensory cortex 2) Somatosensory Association cortex 3) Visual cortex 4) Auditory cortex 5) Olfactory cortex 6) Vestibular cortex 7) Gustatory cortex 8) Visceral sensory cortex
Primary Visual Cortex - extreme posterior tip of occipital lobe; receives visual information from retinas
Olfactory Cortex Region of conscious awareness of odors
Primary Somatosensory cortex In the post central gyrus; receives sensory informatin from the skin, skeletal muscles, and joints
Vestibular Cortex Resposible for conscious awareness of balance (position of the head in space)
Gustatory Cortex In the insula; involved in the perception of taste
Auditory Complex Stores memories of sounds and permits perception of sounds; interprets information from inner ear as pitch, loudness, and location.
Visceral Sensory cortex Conscious perception of visceral sensations, e.g upset stomach or full bladder
The ___ matter of the spinal cord is made of ____ fibers responsible for communication between cells white, myelinated
_____ connect ____ matter of the two hemispheres. The fibers cross in the _____ from one side to another. Commisures, gray, corpus callosum
_____ fibers connect different parts of the ___ hemisphere. Association, same
____ fibers connect the cortex (upper part) with lower parts of the ____ or the ____ Projection, brain, spinal cord
The ____ system is our emotional or _____ brain. Limbic, affective
The _____ is the part of the central nervous system below the _____ of the skull. It has two enlargements created by neuron and axons that serve upper (_____ enlargement) and lower limbs (_____ enlargement). spinal cord, foramen magnum, cervical, lumbar
Its lower end is called ____ _____. The _____ is fibrous extension that anchors the spinal cord to the ____. It is also secured by the _____, extensions of the pia mater to the dura mater. conus medullaris, filum terminale, coccyx, denticulate ligaments
The ____ are membranes that cover and protect the brain and blood vessels, enclose venous sinuses, and form partitions in the skull. They have 3 layers: meninges
The _____ is the strongest meninx. It has two layers, one that is attached to the bone (___ layer) and a deeper _____ layer that continues below the foramen magnum as the dura mater of the spinal cord. dura mater, periosteal, meningeal
The middle layer is separated from the dura by the _____ space. It has web like extensions that lead to it being named ______. ?, arachnoid matter
The innerpost ______ is a delicate membrane that clings tightly to the brain pia matter
2 Dural folds: falx cerebri, tentorium cellubi
The _____ runs from the _____ in front along the ________ between the two cerebral hemispheres. The much smaller ______ runs along the ____ of the cerebellum and the ______ is a tent-like structure that separates cerebrum and cerebellum. falx cerebri, crista galli, longitudinal fissure, falx cerebelli, vermis, tentorium cerebelli
