Central Nervous System
| Question | Answer |
|---|---|
| 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 |
