QuestionAnswer
What does the cerebrum control? concious though processes, intellectual functions, memory storage and processing
what are the deep grooves in the cerebellum called? fissures
what are the elevated ridges called? gyri
what are the shallow depressions called? sulci
what does the cerebellum control? coordinates repetetive body movements
what are the hemispheres of the cerebellum separated by? vermis
what are the divisions of the diencephalon? the left thalamus, the right thalamus, and the hypothalamus. links the cerebrum with the brain stem.
what is the function of the thalamus? relays and processes sensory information.
what is the function of the hypothalmus? controls emotions, hormone production, homeostasis, and autonomic functions.
what is the pituitary gland connected to? the hypothalamus by the infundibulum
what are the pituitary gland and the hypothalamus responsible for? integration of the nervous and endocrine systems.
what is the function of the brain stem and what structures does the brain stem include? processes information between the spinal cord, the cerebrum, and the cerebellum. Includes the mesencephalon, the pons, and the medulla oblogata
what structure processes vision, hearing and associated reflexes and maintains conciousness? the mesencephalon
what structure connects the cerebellum and the brain stem and is involved in somatic and visceral motor control? the pons
what structure connects the brain to the spinal cord and helps to relay information and regulate autonomic functions? the medulla oblogata
what are the first two ventricles in the brain separated by? the septum pellucidum
how do the lateral ventricles communicate with the third ventricle? the intraventricular foramen
how is the fourth ventricle connected with the third ventricle? the mesencephalic aqueduct
what are the layers of brain protection? 1. layers of skin, 2. periosteum, 3. bone, 4. dura mater, 5. arachnoid mater, 6. pia mater, 7. cerebrum
what are the layers of the cranial meninges? the dura mater, the arachnoid mater, and the pia mater.
what does the cranial meningies protect the brain from? cranial trauma.
what is the function of the dural folds? extend into the cranial cavity, stabalize and support the brain, and contain collecting veins:dural sinuses.
what does cerebrospinal fluid do? surrounds all exposed surfaces of the CNS and interchanges with intersitial fluid of the brain.
what is the function of CSF? cushions delicate neural structures, supports the brain, and transports nutrients, chemical messengers, and waste products.
what is the choroid plexus? consists of ependymal cells that secrete CSF into ventricles. also adjusts composition of the CSF.
what is the circulation of CSF? from choroid plexus to ventricles to central canal then into subarachnoid space of brain and spinal cord. it is removed via arachnoid granulations into venous sinus.
what is the vermis? a narrow band of cortex that connects hemispheres
what is the folia? surface of the cerebellum, highly folded neural cortex
What structures do the penduncles link nerve fibers with? the brain stem,the cerebrum and the spinal cord
what is the arbor vitae? a network of axons extending from the cerebral nuclues
what are the two pairs of sensory nuclei? superior colliculus and inferior colliculus
Where are the cerebral penduncles? on the ventrolateral surface of the diencephalon
