Brain Anatomy and Functional Regions

Anatomy Ch. 13 Question The cavities within the brain are called: The __ aqueduct connects the third ventricle with the fourth ventricle. Which brain system is considered to be the "emotional" brain? The left and right sides of the thalamus are connected by which of the following structures? Cranial nerves are part of the __ nervous system. The medulla oblongata is continuous with __ __ inferiorly. gray matter shallow grooves deep grooves Regions of gray matter in deeper white matter. elevated fold The primary auditory cortex is located in the __ lobe. The primary olfactory cortex is located in the __ lobe. The primary visual area is located in the __ lobe. The __ is the location of conscious thought processes and the origin of all complex intellectual functions. There are __ pairs of cranial nerves. The cerebrum is composed of two halves, called the left and right __ __. The gnostic area is composed of regions of which of the following cerebral lobes? The mesencephalon is also called the __ and forms the superior portion of the brainstem. The two functional brain systems which are composed of structures that are scattered throughout the brain are the __ formation and the __ system. The __ provides rigid support that protects the brain. In the cerebrum, the outer layer is made of __ matter and the inner layer is made of mostly __ matter. Which of the meninges is the strongest? The __ connects the cerebrum and the cerebellum to the spinal cord. The areas of the cerebral cortex that are responsible for the integration of new information with stored information are the __ areas. The __ is responsible for "fine tuning" skeletal muscle movements. The blood-brain barrier is not absolute. What are some items that can pass through this barrier? The hemisphere that controls language in most people is the __. The __ is the principal and final relay point for sensory information. __ bathes the exposed surfaces of the central nervous system. From deep to superficial, the cranial meninges are the __ mater, __ mater and __ mater. The __ refers to the paired oval masses that lie on each side of the third ventricle between the anterior commissure and the pineal gland. The components of diencephalon includes what? The cerebellum is responsible for what function? Wernicke's area is located in the right hemisphere. T or F? The posterior portion of the epithalamus is the location for what? Answer ventricles cerebral limbic intermediate mass and interthalamic adhesion peripheral spinal cord cerebral cortex sulcus fissures cerebral nuclei gyrus temporal temporal occipital cerebrum 12 cerebral hemispheres parietal, occipital, temporal midbrain reticular and limbic cranium gray, white dura brainstem association cerebellum nicotine, some anesthetics, alcohol left thalamus CSF pia, arachnoid, dura thalamus hypothalamus, thalamus, epithalamus coordination of skeletal muscle movement false pineal gland and habenular nuclei somatosensory cortex The thalamus will process incoming information and project it to the __. The __ __ are used to be called Broca's area and located in most individuals in the left motor speech front lobe. The limbic system is responsible for what functions? The cerebellum is the second largest part of the brain? A sensory area known as the __ association area allows us to identify objects with our eyes closed. Cranial nerves are numbered according to their positions, beginning with the: Most of the central white matter is grouped into bundles called __. The __ cerebelli forms a dural "tent" over the cerebellum. Cranial nerve II has what functions? The __ mater's literal translation is delicate mother. The __ extends inferiorly from the hypothalamus to attach to the pituitary gland. The arachnoid mater is partially composed of __ and __ fibers. The __ formation processes visual, auditory, and touch stimuli and sends inputs to the cerebrum to maintain alertness of the organism. The falx cerebri is a fold of: All of the ventricles contain a liquid material called __ __. CSF is produced by secretion of a fluid from the __ cells. What cranial nerves are found in the mesencephalon (midbrain)? CN I (Oh) CN II (once) CN III (one) CN IV (takes) CN V (the) CN VI (anatomy) CN VII (final) CN VIII (very) CN IX (good) CN X (vacations) CN XI (are) CN XII (heavenly) Four main regions of the brain: Biggest part of the brain. Right and left hemispheres. Contains thalamus, epithalamus, and hypothalamus. Contains midbrain, pons, and medulla oblongata. Depressions of the brain. Shallow groove. Deep groove (sulcus). Folds of the brain. The __ __ is an external, tough, dense irregular c.t. layer composed of two fibrous layers. The __ __ is immediately superficial to the arachnoid. The _ _ is more superficial layer; forms periosteum on the internal surface of cranial bones; (venus sinus). Between dura mater and cranium: "potential" __ space. Between dura mater and arachnoid: "potential" __ space. __ mater resembles spider web (trabeculae-collagen and elastic fibers). Immediately deep to arachnoid mater is __ space. Filled with trabeculae and vessels. CSF. "Tough mother." Outer meninge. Middle meninge. "Delicate mother." Inner meninge. The __ mater is the innermost of the cranial meninges. It is a thin layer of delicate areolar connective tissue that tightly adheres to the brain and follows every contour of the brain surface. motivation, emotional memory, emotion true somatosensory nerve that is most anterior tracts tentorium vision pia infundibulum collagen, elastic reticular dura mater cerebrospinal fluid ependymal oculomotor nerver (CN III) and trochlear nerve (CN IV) olfactory optic oculomotor trochlear trigeminal abducens facial vestibulocochlear glossopharyngeal vagus accessory hypoglossal cerebrum, diencephalon, brainstem, cerebellum cerebrum diencephalon brainstem sulcus fissures gyrus dura mater, meningeal layer, periosteal layer epidural subdural arachnoid subarachnoid dura mater arachnoid mater pia mater pia
