TCDHA Anatomy & Physiology Test 3

TCDHA Anatomy & Physiology Test 3 four main divisions of the brain? - Cerebrum, diencelphalon,cerebellum,brain stem What is the largest part of the brain? - Cerebrum The cerebrum is divided into _____&_____ hemispheres? - right & left Which side of the body does the right hemisphere control? - Left What two structures protect the brain and spinal cord? - mennings, CSF what are the channels formed where the dura mater divides into two layers? - dural sinuses How many layers of menings are there? - 3 what are the names of the three layers of the menings from the outermost to the innermost? - dura mater, arachnoid, pia mater which division of the brain is physically connected to the spinal cord - Brain stem Which pard of the brain stem contains relay centers for eye and ear reflexes? - midbrain where is CSF produced? - choroid plexus within all four ventricles What does the corpus callosum do? - bridges right and left hemispheres of the cerebrum permitting impulses to cross from one side to the other what are the two main portion of the diencephalon? - thalamus, hypothalamus which structure controls autonomic nervous system and the pituitary gland? - hypothalamus 3 parts of the cerebellum? - cermis, left and right hemispheres functions of cerebellum? - coordinate voluntary muscles, balance, muscle tone. which is not a function of the cerebellum? - initiating movement What two structures is the limbic system located between? - Diencephalon and cerebrum what are the names of the three coordinating neurons networks that involve multiple regions of the brain - limbic system, basal nuclei, reticular formation function of limbic system? - initiates hunger, aggression, emotional feelings and sexual arousal. function of the basal ganglia network? - controls complex patters of body movement (writing ABC's) what two degenerative diseases can result from damage to the basal nuclei network? - parkingson and huntington disease functions of the reticular formation network? - awareness and screens out unnecessary sensory stimuli such as traffic noise allowing a cars horn to be heard what type of hematoma forms outside the dura master?
